I just got a supra turbo i need help please!!!

[bradenman1]

I just got a 1990 supra turbo. It has a few problems that I need help with

1. The valve cover gasket is leaking oil I saw that all the valve cover bolts are philips head?? I would think that this would cause alot of leaks due to the fact that you can't torque them like a hex head. I would like to know if there is any replacement bolts I could get to fix this leaking problem.

2. Ok the turbo boosts still to about 5 or 6 psi (is that normal boost or should it be higher?) but it seems to only be within 3000 and 4500 rpms or so, once it pases this point it doesn't seem to pull verry hard. It does have 237k miles on the car and the turbo was never rebuilt. And theirs also an exhaust manifold gasket that is blown and I'm almost positive that the cats and exhaust system is cloged. Would this cause the slugishness to happen?


I'm sure there's more I just can't think right now. Please help. Thanks : )
