As she was telling me about it, I told her the exact same thing that she should have asked to see the defective parts. I figured the gasket might be reusable and yes, even at $400 it is now running good and they are just happy to get the daughters car back to work, I just cant imagine a cylinder having 150psi in a cylinder with a broken valve spring.
I just thought I would share the results with you guys who have given me suggestions.

These are interference engines. If a valve hangs open enough, it'll hit. It sure sounds odd what they said. While you can bolt a valve cover back down without changing the gasket, you can also cause a leak. These gaskets are well known to flatten with years and if this does cause a leak, replace the valve cover grommets at the same time. They apply the pressure from the sleeved bolts in order to seal the gasket.
I drink..so consider that when reading my posts.

Tes, it is running fine now, and they were satisfied with the $400 price. I told her if it ever happens again to request the old parts. Ive been teaching HS automechanics for 38 yrs and I am baffled how a broken valve spring can still make 150 psi but.....
Thank you for all your help guys. I appreciate it.
