I was driving Jeep Cherokee.

Ok, guys, first and foremost feel free to challenge anyone technically but don't use foul language please, it spoils the whole decorum. We all are grown up and should stick to better language and communication while dealing with technicalities. Coming back to Asif bhai truck issue, I suspect the same and I have been involved so far with so many self-tests during that drive and seen the symptoms too. Coolant doesn't seem to have any traces of oil and looks crystal clear (visually). Engine oil seems crisp golden without any presence of coolant or water and has no foul smell. Exhaust has no fuel smell while placing the hand for a few seconds. The car has no loss of power yet. The only thing fishy in the whole diagnostic seems is cylinder 4 throwing the water droplets out, that point to minor head gasket leak. I suspect that HG leak is directly near the exhaust valve and that's why water is resulting in the white smoke at the exhaust and exhaust gas is pushing in the radiator to make air pocket to push coolant to the reservoir. While driving after sometime cylinder temperature is so hot that leaking water droplets cannot produce steam and hence white smoke is disappearing. This is my educated guess. What desertdude mention to inspect cylinder 4 internal with a flashlight to see the color seems good point as if you can differentiate that appearance with neighboring cylinder then that can confirm the leak. Wait until Saleem can confirm the factory spec for compression results. @Barry @desertdude @shadow79 @treks is it normal to have faulty (leaking HG) cylinder to have higher compression?

Fantastic, what is his car? Really nice drive, see you there

Might just be a faulty water pump but sounds like it has overheated and the head gasket is damaged. Next step is to perform a sniff test and check for the presence of hydrocarbons in the coolant reservoir. Can be done by sticking the probe from an exhaust gas analyser into the air space in the tank as long as it doesn’t touch the coolant. If this confirms it, head/heads will need to be removed and inspected for flatness along with the block deck. If you’re lucky, it might just be a split gasket which will be visible upon inspection. Get a sniff test done and post the results and I can offer better advice after that.

Did you actually remove the fuel pump relay when the compression test was done...? Let me check those numbers with the factory service manual specs will post them here tomorrow when I am at shop There is a coolent analysis kit which changes color if there is combustion chemistry escaping into the cooling system...it's available at sedana Sharjah but is quite expensive somewhere in the north of 300. I once bought it for diagnosis of a Lc which had a very weird heating issue which was making me confused between radiator , clutch fan,water pump and the head but after using the kit had to pop the head.

Ford Explorer Sport Trac, 2010 Model. V6, 4.0Ltr Problem started with the coolant going to the reservoir and not returning back to the radiator when the vehicle is cooled. First, it started on my trip to salalah in Aug 2018. After driving around 900kms continuously (with enough breaks every 200 kms) with 45 to 50deg outside temperature the engine light came on and felt some hard jerk. We stopped and noted that the coolant reservoir was full and was overflowing with the boiling coolant. We waited till the vehicle cooled down and we shifted the coolant from reservoir to the radiator manually and continued our journey to the nearest town where we found a mechanic. He said, it is because of faulty radiator cap and he replaced it with a 88kpa while the original ford radiator cap is 140kpa as we had no option left. Then, we continued our journey without any issue and drove around 1000 kms in salalah for the next 5days with (18 to 22deg outside temperature). I tried to find the original radiator cap in salalah but I did not find there because ford parts store was closed for Eid holidays. On our way back to UAE the same problem happened again after driving for almost same distance around 950kms continuously (with enough breaks every 200 kms). We repeated the same procedure of coolant swap what we did earlier and reached home without any issue. Next day i replaced with original radiator cap and the problem was solved for next few months. And engine light error was due to the fuel rail pressure sensor which i replaced and everything was normal. Now the problem occurred again 15days back. Last week during our desert drive the heat gauge raised for first time and at one point it touched to the max. Now it is something serious and require our expert advice and figure out the exact problem and the cause. Problems: 1) Coolant is going to reservoir (almost full sometimes and over flows) and not returning to radiator back once vehicle is cooled. 2) White smoke is coming out from exhaust when idle. While moving it disappears. 3) Water dripping from exhaust in idle 4) Coolant level is going down (may be over flowing from reservoir) 5) Misfires in idle, While moving can’t feel anything. Aslo sometimes misfire stops in idle for some time and starts again. I have a Chinese OBDII scan tool which connects to smartphone via bluetooth and it read a faulty code P0304 cylinder 4 misfire. Note: Checked the coolant no traces of oil found. Checked Engine oil no traces of coolant found. Steps taken : With my little knowledge i tried all these steps: First thing i did was i swapped the spark plug from cylinder 5 to 4 and 4 to 5 (No luck it misfired) and the OBDII read the same cylinder error. Then i went to used part shop and borrowed 2 sets of plug wires and 2 coils, swapped and checked (No luck it misfired). Finally i did dry compression test and here are the result Results Cylinder PSI Cylinder PSI 3 165 6 170 2 158 5 160 1 165 4 168 I repeated the test for the 4th cylinder twice again and the PSI shooted up to 205 and 210. And at that point i noted water/coolant coming out from spark plug hole. Need some expert advice to figure out the exact problem and cause.

I can fix cars but nobody ever said I was stable or well adjusted.

And losing your shit on an internet forum is also a sign of blowing your head gasket! LOOOL

Just to put some stuff to bed, Oil in the coolant is a sign of head gasket failure Coolant in the oil is a sign of head gasket failure Bubbles in the coolant is a sign of head gasket failure Disappearing coolant is a sign of head gasket failure Low compression across 2 cylinders is a sign of head gasket failure Water in the exhaust is a sign of head gasket failure Overheating is a sign of head gasket failure A failed head gasket can cause any combination of these. The symptoms can also be caused by unrelated problems. The head gasket separates the combustion chamber, oilways and waterways. But just because some symptoms are showing, it’s both wrong and unprofessional to jump to conclusions and pull an engine apart because you think you know better. Proper diagnosis should be made first. I’ve seen a guy with a X5 recently paying for a full rebuild when all he needed was a jubilee clip. But he knew better so I said ok, get a rebuild. He came back to me 6k later complaining his car was still overheating. A 10 minute pressure test would have told him that. E.g. Creamy mayo on the filler cap? Yeah, might be a gasket problem, might also be a faulty oil cooler, maybe even just condensation because of winter. Nah, let’s pull the engine apart and stick a new gasket in. Make proper diagnoses and fix things properly first time instead of guessing and getting lucky. I didn’t get to be working on expensive cars just by guessing things. If I was into the guessing game, I’d rent a parking space in rashidiya and survive on 100 dhs per day. There’s nothing UK about it, it’s called being professional.

And the same dealership would be the first one to refuse to carry out any repairs under warranty if something conked out due to offtoad use. I totally forgot the new Sheep has EAS but even in full height its not too great, better but not too great. but decent enough for newbie drives Im guessing People do this all the time with range rovers so see if its possible with the sheep too. They just reprogram the off road height to be a couple of inches higher than what came from factory pretty painless quick and cheap. I can reprogram the height of my Range Rover in any of the modes, access, normal or off road to be any height that I choose to be. Within reason ofcourse. Any place with a good diagnostic tool for a jeep should be able to do that in 10-15 minutes. But STILL I wouldn't take me new car off to the desert specially when I dont know what I doing. If you were a seasoned off roader I wouldn't be so skeptical.

Here are the readings

Gentlemen... First of all....i am really feeling good about the number of people actually providing me with a lot of suggestions and feedback....it really shows signs of good spirits....i would really want to appreciate everyone here.... Second....the pictures you had seen about my car.....front side.....well the car was on park mode....which is why it might seem to be lowered....so the vehicle has an auto suspension based on the different modes of drive....as per a very recent conversation with trading enterprises....they to safeguard their brand and model were justifying that the car has various suspension modes and power to make it offroad friendly.....i have attached pix in both park mode as well as offroad 2 mode which is the highest in the car. as well as the various stats that show in the display during offroad...for which I would still require your expertise if its still recommendable or not.... However the front tow hooks could be very tricky....as @Gaurav had suggested to check with trading enterprises to swap the bumpers with the trailhawk version......upon checking with trading enterprises...they mentioned that even though it falls under the grand cherokee family.....the body of summit is wider than the trailhawk, overland or laredo version...and indeed i could still upgrade to the SRT or trackhawk body kits as the body size is the same to that category.....Summit is more of the luxury range but with a 5.7liter and 407bhp power under the hood....I would still need to check with some pro garage guys if i could probably get the hooks in front installed custom made without doing much that could affect the warranty.... Thirdly....i might not be approaching the right guyz for insurance....but i have been getting refusals saying offroad insurance is not what they would add on to my policy....i need to do more R&D on it..... I am happy for the suggestions you guyz have given me to get the tools for offroading from Dragon mart and ACE hardware...but i guess sorting out the other technical aspects is on priority....

Been there done that, last year spent and entire day lying flat on an engine trying to undo one 10mm nut that was sandwhiched between the back side of the motor and the firewall , it was not visible so it had to be done by feel and could get only a quarter turn at a time, once spent an entire week trying to pull out an axel half shaft out from the front differential tube one side came out quitely without any issue but the other side was hung up on something, tried everything, heating, pullers, impact guns, jacks.Opened the diff cover so see if we could trying to massage it out from that side or a C clip we were not seeing Seemed like it was welded in their, we were even caught by the cops and taken to the police station because we were working so late at my buddys shop one day. Not a good sight with three greasy dudes looking very suspect at a police station. Eventually we all gave up and changed the entire front diff tube with a used one from the scrappies

The head gasket not only seals the cylinders but also seals the oil and coolent in between the head and block so there can be gasket failure yet you might find compression numbers up to company specs... compression test only indicates how well a displacement chamber is sealed if you have the factory numbers to compare them with....and just incase there is a leak in the chamber you can further diagnose it to pin point it to rings or valves by pouring some engine oil in it to seal the Piston sides and get new readings and compare those with dry readings If the misfire is continuous then you should check the flow pattern and spray quantity of injectors P.s if only driving on and off road and being a cloud nine machanic has made you loose your rocker then you really don't have the slightest idea of profanity,rage and inventions of swearing up and down goes through. when working for one too many days and yet sometimes being still on square 1 feels like . Or being in middle of something really delicate and that tool slides through in to the engine bay and you using up all the scheduled time only to find that instead of fixing it .or stripping of that bolt which is placed in that corner of the world where only your 2 finger goes only to feel it's head and a spanner only runs quarter of a inch This work has turned me swearing like a sailor but I try really hard to be as professional and all ears so I can be remembered with good words and good works

@Asif Hussain have you done the compression test when the engine was at idle temperature......? It shouldn't be cold readings.

Wowza somebody got up on the wrong side of bed today, eh! Too much grandads cough medicine over Xmas perhaps? Anyways when you are trying to do things on a shoe string budget 250dhs and 40-45 day wait for stuff to arrive only to tell you what you already knew can throw a spanner in someone's schedule, specially if that is someone's only ride. It's throwing water out the exhaust, misfiring and coolant is disappearing after being fully overheated 9.5 times out of 10 is a blown HG. If the hat fits, wear it. P.S : You're not the only one who knows a thing or two about cars in this place. So don't think you are only one here with "informed" advice. Yeah so it will be appreciated if you think twice before wearing your superiority suit and labeling everyone else as a no nothing grease monkey Cheers and Merry Xmas

I was in Al Quoz earlier and I spotted what looked like a L200 but it said RAM on the tailgate. I did a bit of research and it turns out it was a Dodge Ram 50 which is based on the Triton/L200. This is one of the things I love about UAE. No matter how much you think you know about cars, most days you’ll see something oddball and ask yourself WTF was that?

I have just marked the simplest track to new year site so that people driving 4x4 can directly reach within 3 minutes without getting lost in bushes or small dunes. This track doesn't need deflation, engage on 4x4 and keep gas little high to traverse through.

Totally agreed with you, same here, but I have to do something for car traction control, anytime I need power the engine stop down, Thanks alot brothers @Rahimdad @Gaurav @skumar83 @Asif Hussain for help and guidance

I totally agree @Mick, that everyone should enter desert with real men who understand this extreme adventure and behave in a responsible and civil manner than just being kiddish like immature boys.

No i did"nt... just removed the coil connection
