No experience with this but I would think a spun CR bearing would fry a crank journal pretty quickly. Anyway, I vote for dropping the pan and checking #6 CR journal ASAP. I recently did the in-car replacement of all the CR and Main bearings and it was much easier than I feared it would be. The only difficulty is fashioning a little tab that sits in the oiling hole that will gently roll the upper main bearing out the bottom when you rotate the crank by hand. It must not scratch the crank. |

Is this a V6? What was your engine mileage? Did you have symptoms or just preventative maintenance? Did you use aluminum or tri-metal bearings?
I'm a little shocked my engine did this so young. I don't drive it hard, use synthetic and haven't let the oil pressure drop low.
I got all the parts in Monday (rod and main bearings, oil pan gasket). Will be starting on the job on Thursday.

I had a worn crank bearing on my Fiero when it hit about 120k miles. For me, I had installed one of those Coltec Industries water pumps that had the plastic impeller. It was a great water pump while it worked... very efficient. Eventually though, the impeller broke free from the shaft and it overheated spectacularly. Damage was done... trashed my bearings.
But at the end of the day, these are 1980s GM engines, not the best time for quality control... and 120k is about the life expectancy. A lot of people get more miles, but the early to mid 80s was just a really bad time for GM quality control.
I got 150k out of my 305 V8 in my 82 TransAm before everything dumped out the bottom of the oil pan.
