Hey guys let me start off by saying this forum has been a huge help with my new pony. Anyway I have a huge problem. Being a total novice when it comes to internals I was hoping someone could get me pointed in the right direction.

Last week I was getting a pair of Stage 2 Thumprs in and I decided to keep my stock springs. Bamachips had them posted as not required so I thought everything would go smoothly. Later that day I receive a call from the shop saying that the engine dropped a valve. They said it could have damaged a piston and cylinder wall. That i may have to replace the block and that going with a built engine might be a cheaper option. What should I do? I'm not going to know the exact damage until tomorrow when they pull the engine, but I was wondering if someone could give me some ideas.

Thanks in advance for the help.

 

They dropped a valve during installation? That wouldn't cause any damage unless they did something stupid like rotating the engine while the valve was in the cylinder.

 

What does that mean, "Dropping a valve"?

 

They said it dropped after 3 minutes of iddling.

 

There is a retainer that holds the valve to the spring so when the valve needs to close the spring will pull it into position. When you compress the spring manually using a spring compressor (during camshaft installation) you have to make sure the valve moves down with the spring otherwise the retainer can come out and there will be nothing from stopping the valve from dropping into the cylinder.

It sounds like they messed up the install. Unless the spring failed (which it shouldn't have) they damaged the retainer during the cam install.

Did they give you any more information about the failure?

 

I'd get a lawyer if they aren't willing to fix it on their own dime. Sounds like they F'd up and are hoping you don't know it.

 

i agree. it sounds like the install was botched,imo. take pics and post! the only issue i had with the same cams, was iddle...but the tune cleared that up
good luck

 

They got real technical and honestly all I can recall was that my stock springs couldn't support the aggressiveness of the cam.

 

(SIGH)

 

Aggressivness of the cam my ***!
There isn't a cam on the market that will fugged your stock springs.
Unless it's a total custom grind made by some local shop, but it's not even sure that would stress the springs.
If you had a full build mill with FI, that might be a different story.

Like it's been said, those guys are trying to take advantage of you.
Don't let them do that. Good luck man.
