Originally Posted By: JennyHemi Hmm, I hadn't thought of the gas - I always use 92, and always get from the same station That could be an issue. Using to High of an octane gas leads to carbon build up. Higher octane gas burns slower than Lower octane gasoline. Does your car's engine...

So the consensus here would be gasoline engines can "usually" obtain around 200k miles and on borrowed time after that ?

Originally Posted By: MC5W20 Over the years I have heard several people claim mileage's of 600,000 to 800,000 without engine rebuilds. I have never seen the odometer on any of these claims. I've never heard of this either on gasoline car/pickup engines. However, that type mileage is not...

I've also read somewhere that the 4.3 rod bearing journal diameter is SMALLER than that of V8s. Also, here's an interesting article on the 4.3s rod bearing failure issue. http://www.hotrodders.com/forum/4-3l-v6-rod-bearings-124422.html Quote: As for 4.3 bearing damage. I was told by a bearing...

Originally Posted By: chevyboy14 What are common issues with the 4.3 that I should be aware of? Thanks guys. SPUN ROD BEARINGS are extremely common on 4.3s over 125k miles. SERIOUSLY! I've had (2)4.3s go bad after 125k. One spun a bearing and started knocking, the other simply froze up as I...

Originally Posted By: chevyboy14 Ive heard of that with the 4.3 but never seen it. Mine had 207,000 and is fine I've had (2) 4.3s that went South early. One spun a bearing at 129k. And another 4.3 that froze up (locked up rod/crank bearing(s)) at 125k. I was simply backing up out of my driveway...

Originally Posted By: chevyboy14 The engine itself can last over 1 million miles. On the otherside of the coin is engines that seem to self-destruct early. I know many 4.3 GM engines that tend to get spun connecting rod bearings after they reach around 125,000. Ford also had issues with their...

Nowadays we are routinely seeing cars go 150,000 - 200,000+ miles. Given proper routine maintainence (oil type, changes etc..), how far can car gasoline engines (bearings, rings, cylinder walls, valves etc...) go before giving up the ghost ?

Nowadays we are routinely seeing cars go 150,000 - 200,000+ miles. Given proper routine maintainence, how far can car gasoline engines (bearings, rings, cylinder walls, valves etc...) and trannys (clutch packs, synchros, gears) go before giving up the ghost ?

Originally Posted By: calvin1 It didn't tick after I changed the oil. I don't think it was the GC that was causing the lifter tick Cool. Thanks for the fast reply and info. BTW, what is "GC" ? Are you on www.bimmerforums.com ? Great website. The forums are broken down to specific models. Very...

Originally Posted By: calvin1 For reference the upper sprocket is on front end of the crankshaft. You can also see the front-most bearing and crank set. The varnish doesn't really seem to be hurting anything but as it sheds it does load up the oil quickly. I have a 94 530I with a M60B30 as...
