Has anyone ever heard of wristpins going bad on a Lt1 with 131,000 miles? I've had a couple of places tell me that's what's wrong with the car. I just replaced the lifters about 3,000 miles ago and the my roller rockers aren't loose. Just wanted some opinions before I buy an extra block and build it on the side.

 

Doubtful. Mine had 267,000 on it and they were tight as can be.

 

Is it just a tick or is it a TAP?

When I have seen wrist pins wore out you get like a double TAP.

 

It's a TAP.

 

I'll bet it's a spun bearing then if its a nice TAP. Can you feel it from the drivers seat?

 

I can't feel it from the drivers seat, but I can hear it. My oil pressure is also fine.

 

Get you a mechanics telecsope and locate the noise, it could be just a lifter.

If it keeps getting worse and louder and the oil pressure starts acting funny it's definatly a spun bearing.

I would locate it before I drove it more than a block or two away.

 

I had a wrist pin go bad at 129k it was a tap too..
