my friend picked up a 91 gst the other day, drove it home, he said it ran like shit, wasnt boosting much... so yesterday he goes to start it, it cranks but doesnt fire.
did a compression test and it isnt reading anything on all cylinders.
we did notice something that i thought was odd... the rockers on the exhaust side are all tight against the cam and dont move, but the intake side rockers we could just tap em with a finger and they would fall out..
what yall think?

Timing belt.

could be.

that was my first guess

I'm going with the timing belt too.

thanks guys..

you'd think i would know this by now considering how many times the timing belt has bitten me in the ass

anyway, now i gotta call him and pass along the good news
