I dont know how i missed it but the failed valve had the bottom of the spring broken.Now i can see why the valve hit the piston and destroyed my new baby!Where do i go from here.Are the spring manufactures going to pay for another motor.......I have been kickin myself in the ass for the last few days thinkin I caused it....Yes the valves had touched the pistons,but not enuff to kill it.So I say......
:sux2bu:Pay up SUCKAS!
PRCs? ? ? Dang I hope not those are the springs I have.
I wondered. I had more faith in your cam swapping ability's than that.
I thought all the pistons had marks on them.
The valve hitting the piston is what caused your problem. Don't expect the spring company to buy you a new motor...
if you had PTV the spring isnt going to do nothing but break. a spring is ment to hold the valve stable not cusion it from the impact of hitting a piston

Don't think spring failed first , like Quik said piston slapping valve broke spring .
Dang didn't knock sensors go off from all the metal to metal ?
Bore it out , slap some pistons in it , put some 317s on it and have 6.0 Liter the hard way .
I am torn here... From the looks of things, ALL of the intake valves were hitting the pistons. BUT if a spring DID in fact break, then that would have caused the engine failure.
LS1 aluminum 5.7L motors can be bored out to .010--nothing more. The block thickness cannot handle more than .010. But you can bore it out and re-sleeve it...back to a 5.7L displacement.
Ha Ha, Tyler, where'd you learn that? :laugh:
Get it sleeved and it will be fine but don't ever spray it, the sleeve will collapse and you'll be redoing it all over again. Don't ask me how I know. :sad:
YOU.
How do you know? :lol:
You could get a 5.3 core block and have it bored to 5.7 and then put all the LS1 parts in it.
Hmmmm... I think Dale has a 5.3L block just laying around. How convenient! :thumb:
I used to read a whole lot of manuals. Now its just worthless information consuming space in my small mind.
True that!
damm dale,that sux bro,hope you get all these problems worked out.
getting all 8 cylinders bored and honed to 5.7L dimensions is the cheapest mod you can do to build hp on a 5.3L engine. Added benefit is you only need one piston/rod assembly to finish the build. :thumb: Getting it balanced would be great, too. Maybe Xtreme can bore and balance it for you.
Man , aluminum blocks , .10 is all , not good for rebuilds then .Quote:
