The official "I'm screwed" thread
#17
Well I had the same happen to me...front cam bearing was bad. Decided to pull it apart to check the other cam bearings as well, and main and rod, might as well replace those while I had it apart so I did, cylinders were slightly oval so I bored it, new pistons, rings and whatnot
Mine's also a 55-60k car.
Started up with as a head and camchange only. Ended with just the crank, rods and pushrods still stock.
One of those "I'm just going to" that went like many things before...a "tad" bit more than expected. So take the cost you predict...and then at least double it, and there you have a ballpark.

your not supposed to put synthetic oil in a motor with fresh bearings...aka a new car.
wait until you have about 30,000 on the clock before starting with synthetic.
synthetic oil will not let bearings break in like they are supposed to do. it works that well.. you must let your cam/crank and their bearings wear in and create room for the synthetic oil.
i use synthetic as well, pulled mine apart and it looks fine... go figure..

You are not gonna believe this...
Last night I emailed GM off of their website telling them of my ordeal. Within 15 or so minutes I received a response back. Typical stuff like "we do not recommend modifying your GM vehicle" and the usual fluff.
I emailed them back with the picture of the bearing and told them to show it to anyone and ask the question of how many miles they think are on it.
I received a call from the very same person tonight.
Completely stunned me. She wanted more info and asked if I have taken it to a dealership yet to get it analyzed. I told her I would have to check to see if the shop has buttoned it up yet.
If they have buttoned it up, anyone work at a Chevy dealership in Dallas who wants to vouch for me? Maybe they are finally listening to a customer????

As another reference point, when I had the cam changed in my 95 LT1 at 45K miles, the bearings were perfect. That car had synthetic from the first oil change, and was run very hard. I would be wondering what else was going on in the engine at this point to have caused that kind of wear.
