project Z24 SS *slowly but surely...*

Could be from high rpm's, heat, and a slight bending of the stem allowing it to seat improperly.

im going to blame valve float thats all I can think of

my teacher said the way that builds upon the pistons is babying the car to much he said u can clean it (if it wasnt apart) by taking it out on a back road and opening it up i dont know about the valve tho

theres a tiny mark on the piston. its not a deep scratch at all... nothing more than the engraved numbers you see on pistons sometimes

so im not going to worry about that. it looks like an arrow actually

dont worry about a little scratch like that. You should see what kind of mark my pistons had when my cam went. Just smoothed them all down and Ive put 7k on it with no problems

Valve float could have caused that but its hard to say

3400 pistons have arrows pointing to the front side of the motor

good luck with the project man. i keep thinking turbo, but i've got some work to do N/A before i can even begin to think about that

The engine can..... The fuel system cannot.

the arrow should be there so they knew how to install them from the factory

ok I got the new rack installed, and the ls6 springs installed

looks like I need ls1 shims to keep the spring centered, but thats going on the backburner for now

I found 2 injectors that were covered in some sticky oil crap

I think thats why that one valve went now. luckily I had 2 spares since I bought a V8 injector set

looks like I definately need a oil catch can or something was wrong with the PCV system.

it fired right up the first time. ran it for about 5mins then tried giving it a rev. sounded like it was just taking in more air but not revving up at all

so I turned it off and tried restarting - wouldnt restart!

gotta look into that some more not sure whats going on..

heres pics

I have a feeling you'll be back for some boost. You can lie all you want, but deep down you want the FI back.
