Bottom-end life??

569 Views 5 Replies 4 Participants Last post by  97GT4.6
On an engine with regular oil-changes, essentially stock and indicating high oi-pressure it's entire life, what kind of life-span can one expect?

I ask b/c my car has high (165,000) miles on it and I bent a valve. Planning to get away with just new heads as the bottom-end seems tight.

Thoughts?

I know from reading there are quite a few members who know these motors well and would appreciate some input.

The engines will last a while but if you bent a valve you might as well redo the bottom end with your situation anyway. It would be much better for the long run.
I assume it's bent, only b/c it no longer moves! I was doing intake swap and apparently something scraped off and into the intake port on the #1 cylinder as I was removing the intake. I have a mechanic friend with an increadibly expensive camera system that we snaked into the combustion chamber. You can see some debris keeping the valve from seating, and as I said it doesn't move. The piston shows no damage, so I'm not to concerned about the bottom end (piston and valve didn't collide).
As long as it maintains good compression and oil pressure the motor is fine. Theres no reason you cant go 200+.

I agree. These motors seem really really durable. Mine has 153k, and runs really well, doesn't leak, or knock, or burn any oil. I think the bottom end is pretty strong, and will last a while. Although if you have the money, and you want to rebuild it, it might not be a bad idea.
