Why is my LT1 eating pushrods??? help

[BLK_96Z28]

Ok sooo..my LT1 is eating pushrods..(chewing them up)..what could be the problem guys? One is eaten up on the drivers side and two on the passenger side..something to do with the guides right?

Those do not look like hardened push rods. If you are going to use guides, then you need to get harden rods. If they are, then you need to look other places like is the top of your valves flat? How are the bearings in your rockers (if you are running RR's).

[BLK_96Z28]

They are supposed to be comp hardened pushrods.either way i bought some new hardened ones today..was thinking about taking the guides off but i figured id ask first..heads are new so are rockers..brand new , 25 miles on them

[FANTA-Z]

Which guides are you running? Some of them will put the rod in a bind.

[BLK_96Z28]

To tell you the truth i dont know..they came with the heads..i know nothing about them.

[FANTA-Z]

You need to get the GM ones which are setup correctly. I did use some Comp ones I do believe and they worked ok as well.

[BLK_96Z28]

Yea , i need to do something..these dont say what brand they are (dont think any of them do) but its aggrovating me to death..

Check your plates. if there is any sharp edges, file them down so that it's smooth. Those are stamped and could have a sharp edges that are cutting the rods.

Ill check and see

Are the pushrods you are using the correct length, not asking if you assumed, asking if you actually checked them to see?

Second thing that worries me a bit is those shaving have to go somewhere, I just hope they found their way to the bottom of the pan before they found their way into the bearings

[Red Sleeper2]

Thats what I was thinkin Gator.

Is that the only one thats like that so far? None others?





Kinda off subject but being were talkin bout $hit in our oil pans, I found a couple a small things in mine when I took it off. Like a piece of foil paper like stuff, a small piece of plastic. Just hanging out down there. WIERD

Hey Sleeper, there is your answer.

[LT195Z28]

If it was after only 25 miles I'd have to think that the pushrods were just not hardened.

Take a file to some of the others and see if you scrape/flake off.
