tick-tick noise from engine bay - 06' mercedes

Don't shoot me guys for saying this as I don't know whether WD40 is an approved belt dressing or not.

I have tried WD40 to identify which one out of 3 belts is squeaking in my Pajero multiple times. It just that it creates a dalmatian spots mess in the engine bay, so now I put a big towel around and secure it properly before I spray WD40.

TBH it seems this noise is because engine oil is low or what Saleem pointed that there may be some metal shaving, and some internal engine component is not happy.

Using WD40 on drive belts is not a good idea. The stuff contains petroleum distillates that will attack and destroy any belt that contains rubber in very short order.  If you can't get proper belt dressing, non-stick cooking spray also works well to identify noisy belts.

Sad truth

@desertdude makes a very good point. 99% of parts shops in uae have no clue. The parts guys aren’t interested in cars. They just punch chassis numbers into their system to get their 2000 dhs per month salary and they don’t care beyond that. 

I remember rebuilding a supercharger on a MINI a few months ago. MINI dealer said the parts weren’t available from any source. It was a standard Eaton supercharger and I ended up ordering the parts from europe no problem.

Then I needed the oil to fill it. Everyone was like, what’s a supercharger, no oil is not available you have to buy a new supercharger. I went and looked up the GM part number. Simple thing, available all over the world but even the GM dealers said either no such thing or not available. I ended up ordering it from America with no problems. 

Parts shops here suck. They just want to sell fast moving parts from corollas, Kali wali anyone who drives something different. Fast cash is all they care about.

There is a big gap in the market for a garage who is actually into cars and actually wants to source parts. 

 

Btw guys.. i will update yall next week.. i cant see any oil marks in the area i parked so i doubt if it leaked.. i will show it to a garage near me and see what they have to say...

 

I dont think its the manifold if so i might be the first one to get it cracked on a w211... i think its the lifter.. i will check the oil again and take it to fasttrack cuz thats where i got it changed less than 2k kms ago

Just because there’s no external leaks doesn’t mean there are no internal leaks. 

Weak head gasket, valve stem oil seals, piston rings, cracks in the block or head can leak oil into the combustion chamber and see it burnt off. 

Any blue smoke from the exhaust? Weak head gasket, cracked block or head will smoke all the time. Valve stem oil seals will cause smoke on startup and overrun. Faulty piston rings will smoke on acceleration. 

In saying all this, some of the modern engines from VW and Toyota can burn oil at an alarming rate with no visible smoke. 

But, if you see smoke and recognise when it’s happening, it helps in the diagnostic process.

hi guys..

Its been really long since I logged into the forums. Was busy with uni stuff.

Update on the car: Did an engine flush with the liquimoly stuff and changed the oil with 20w50 and added hydraulic lifter additive. Yesterday morning when I start up the car (about 300kms done after the oil change), I noticed the sound is absent... Since it has been always there with me through my ups and downs (lol), I miss it. Having kind of a feeling that it will come back.

I know for sure it wasn't the exhaust manifold... Anyway.. the mystery sound is gone. I have been hearing that sound on a daily basis for about a month and a half. Sometimes it was too loud and sounded like someones beating the engine with a hammer, and sometimes it sounded like the sound which the chain of a bicycle makes when running freely. lol i know this is weird

here's the link to the video which made the chose this route

20w50 is too heavy for that engine. If there is a knocking or tapping noise the heavy oil is just masking it but the wear is still taking place.

the garage I give it to never told me anything about the oil. I thought they would have replaced it the same oil as mentioned in the service sticker.

Anyway, I will get it corrected next time. It's a 5k km oil

any bad effects on this? it used to be 5w40 and i was kinda shocked too when i saw 20w50 on the new sticker.

If i was you i would remove 20w50 oil from that mercedes right now. It is too thick and old tech oil for that car. And as i know if you make the car get used to the thick oil you may have problem later.

Go with whatever vehicle manufacturer says in term of the specification and get from reputable oil change service station and not just drum dealers - you know what I mean.

Go to Mobil 1 (my first choice) or Castrol service center in Dubai and Sharjah they can change in less than 30 minutes.

      The Lotus Cars return to Dubai with a brand-new 5,000 square foot showroom located on the Sheikh Zayed Road and just a few minutes drive away from the McLaren Showroom. Lotus previously had a showroom in Dubai Festival City which was opened in collaboration with Al-Futtaim group back in 2013 but unfortunately, it was closed now.
      This time, the automaker teamed up with Adamas Motors to open the new showroom in Dubai and it is the only Lotus showroom in the UAE. The establishment can accommodate and display up to 10 cars at a time. Moreover, it includes a configuration room where buyers can modify their car by selecting the different trim option as well as a customer lounge for important meetings.
      Adamas has also opened a car service facility nearby with the aim of offering excellent after-sales service and encourage clients to see how their vehicle will be serviced by trained professionals.
      Considering the fact that the some of the rare Lotus vehicles such as the Exige Cup 430 Type 25 and the 3-Eleven 430 are now present in the GCC region, the Middle East seems to be an important market for Lotus Cars to enter.
      Are you a Lotus fan as well? Do share with us your opinion about how the entry of Lotus in the Middle East market will affect other automakers.

      UAE is planning a new road project called ‘Maliha-Khor Fakkan’ which is expected to complete in the second quarter of 2019 and will significantly reduce the trip time when traveling both inner cities and going out of the city.

The project is worth Dh150 million and includes four lanes, two in each direction along with a 360-meter tunnel as well. With the completion of this project, the traveling time is expected to reduce by more than 40 percent.
      We believe this is an excellent step to improve the traffic condition of the country and would like to hear your opinion as well.

      Road accidents are increasing every day in Dubai and this leads to traffic congestion in the whole city. To tackle this problem, RTA and the Dubai Police have collaborated to introduce a new Traffic Incidents Management (TIM) system.
      The Traffic Incident Management system was launched officially on 16th September 2018 and was inaugurated by key figures of both Roads and Transport Authority (RTA) and Dubai Police. Special breakdown vehicles were also seen to be deployed at different locations on the Mohammad Bin Zayed Road. 
      Special breakdown response vehicles will be positioned every 30 kilometers on the national expressway road which is approximately 70 kilometers long and connects Dubai with Abu Dhabi as well as Sharjah. These vehicles will be well equipped with latest technologies and communication devices to clear up the accident site quickly and assist the drivers to a safe place. 
      The TIM system is expected to reduce traffic delays by up to 35 percent by removing the vehicles involved in an accident and restoring the traffic flow ASAP.
      This effort by RTA and Dubai Police deserves an applaud as it will definitely improve the traffic situation in the city and ensure the safety of every driver. Do share your opinion about this new initiative and tell us how beneficial it will be for UAE drivers.
