The age of the engine is not so important as is its condition with respect to clearances. If you get a new engine with in-spec clearances, using thicker oil might actually be detrimental during cold starts, since the thicker oil is much more difficult to pump around the engine. In your case, it is difficult to say what caused the big clearances, but as per your above post, it makes sense the engine would have died while driving slowly- when it was on the verge of failing anyway. When you were dune bashing, the engine was running at high speeds, which helped to keep the oil pressure up. When you were driving at lower engine speeds, the lower engine speed could not keep up the oil pressure, causing the loss of lubrication. This engine was on the point of blowing up anyway, and it could have happened on your way to the office, or shops, or anywhere- it is just coincidence that it blew up after a dune bashing session.

Not that it matters because Gaurav's engine is already scrap, but I don't think oil viscosity was the primary reason the engine failed. Think about it- there are hundreds of thousands of vehicles all over the Middle East running on oil formulations similar to Mobil1, and yet their engines don't just blow up without warning. I'm inclined to think that this engine had been running with bigger than normal clearances on the crank, and/or cams, and/or oil pump for a long time, and the engine failed when the combination of large clearances and thin oil reached a critical point, i.e., when the pump could no longer maintain oil pressure with the thin oil escaping from overly large clearances. However, as @desertdudesaid, changing over to a heavier oil viscosity might prevent a repeat of the problem in the replacement engine, but also as he said, make sure the oil is a pure synthetic- no blends or semi-synthetic formulations.

So now I understand why both of my fancy exhaust gas analyzers always read a bit rich- I could never quite match the published emissions figures with my machines. And there I was thinking that my equipment was on the blink; how very stupid I was for so many years!

Kolmanskop, an abandoned diamond mining town in the Namib Desert in Namibia. Most houses in the town are now filled with sand. I mention this only because I was once bitten by a cobra in one such house during one of my expeditions.

Some really weird and wonderful stuff here- http://www.douglas-self.com/MUSEUM/POWER/unusualICeng/unusualICeng.htm The best part is that some of these unconventional engines actually work...

There may be a few unofficial imports still floating about, but I have never seen one.

Toyota imported a few of the 1.6 Tazzes, but for some reason they were not all that popular here, but the AE86 was another matter. They were hugely popular, and some mod boys tuned them into fire-breathing monsters that ate almost anything else for breakfast. I was never into that sort of thing though- for me it was always enough just to build a performance engine on the bench, and what the customer did with it was none of my concern. But who knows, for a suitable cash consideration I might be tempted to come out of retirement for a bit to build a couple of crated LS 1 engines I still have lying about, but until then, I'll continue enjoying puttering around in my bog standard Tazz.

My hatchback is a blue 2004 Toyota Tazz (Starlet, elsewhere), with a carburetted 1.3 2E engine, and therefore nothing as glamorous as anything else posted in this thread. Although some members might find my Tazz a bit boring and pedestrian, I have never had any sort of trouble with it, and it gives me better mileage than my Audi A6, which is why the Audi has only done about 8 000 km in the past four years.

Missing engines... and a few other problems here and there makes for a lot of money for a pile of scrap metal

It's both actually. Compounded by the fact that cars are not built to last.

Grumpy? Me? Never! I am practically a ray of sunshine, especially now that I'm retired from the repair industry. The only reason I stayed in the industry for as long as I did was because I needed lots of money to finance my overland expeditions

I really wish I could take part in this in a meaningful way. I suppose I could write reviews but they will all be negative, since I hate all cars equally, and therefore have nothing good to say about any car.

Yeah, and some of them probably cost the price of a gold mine, too.

Probably the most eloquent response to a forum comment that I have seen for a long, long time...

Also be sure to take proper measurements of the oil pump's internal clearances.

...and you even get the fitment for free

Crankshafts generally do not cause cars not to start. Going by the price of the part you mention, I'd say that they replaced the crankshaft sensor, which is the thingamajig that creates the ignition spark. If so, the problem was clearly not related to the crankshaft sensor, and you should find a proper mechanic next time.

Well, he should be able to save the day when t comes to Pajeros. At one time, he even bred them- he posted about it at the time.☺️

True, but with the exception of the 2.4L engines whose timing chains chewed through a water conduit in the timing cover when the chain started to lose just a tiny bit of tension.

It was never about which is better- it was always about whether it's possible to produce millions of electric vehicles. It's possible, but not feasible.

There is no way of telling for sure unless you have the car scanned for trouble codes. I have a lot of experience with alternative fuel control modules, but that means nothing if I don't have one or more trouble codes to confirm, or eliminate the possibility of a fuel control problem being the root cause. HAVE THE CAR SCANNED- PLEASE. ETA- Sorry about yelling, but have the car scanned- please. Otherwise we can't help you.

I would not put too much store by these so-called "predictions". Given the fact that the electricity generating capacity of most western countries is already under severe pressure, and that it takes about seven years (on average) and about a billion dollars to build a single power station, it seems extremely unlikely that any of these predictions will become reality.

Don't get me started on CVT transmissions. I can't understand why Nissan does not just follow Ford's example and abandon CVT "technology" altogether, which incidentally, is the crappiest idea in the history of the motor car. CVT transmissions that is, not Fords' idea to abandon their use.

I was working in the BMW factory in SA at that time. It was actually a fire fighting appliance based on the very last M3 that was built in that factory before the release of the E36, which I had the privilege to build jigs and some major assembly tools for. Anyway, the joke at that time had it that this particular fire truck was probably the quickest fire truck in the whole world.
