I'm Awesome
Well I have had it back at the mechanic since I had a friend tell me that it sounded like it was a valve issue (either sticking or damaged).
Two weeks later the mechanic is telling me it would be a waste of money to rebuild the upper end since the motor has 200k on it. He was telling me that they looked at the lower crank bearings and they are iffy and really should drop money on a long block.
They said the BBC 454 is known issue on this and they rarely make it over 250k without needing a rebuild. He was quoting something close to 4k to swap the motor.
Thoughts? It feels like this is a snowball that keeps growing when I sign off on the repair to be told it really needs more.
Do you trust your mechanic? Yes, 200k is getting up there, but plenty of these engines make it way past that mark. It's all in the maintenance.
So what was the diagnosis? Is that not what you went there for? That's the first question that needs answered.
Did you have low oil pressure? No mention of that on your symptoms...I'd be weary of their "iffy" observations of the bearings, unless they document that.
I'd get another mechanic to look at it...
