What is the correct way too adjust the valves on a 85 300zx turbo? I bought the car with a blowed head gasket and have pulled the heads and fixing the problem....I was going to put new valve guides and seals in while I had it tore down...My question is do you just torgue them down too a certain ft pounds of torque..? Or do u adjust them like u do on a ford and chevy..Intake and exhaust one cylinder at a time with little lash... How someone know's I'm new too the Z scene... Thanks Guys..

So I just install the cam and lifters and tighten the rocker arm plate back down and i'm good too go...?
Thanks,
Keith

 

Zen Archer is right. You can take the lifters apart and clean them though. Then reassemble and submerge in oil while pumping them till they get firm. This is the best thing IF you aren't going to replace them.

 

Thanks... Another Question....Does anyone know where i can get som cam bearings and a pair of cams....Cheap ?..like aftermarket.... Without breaking the bank for them... All the cylinders are in good shape and good compression...Or I will do it all....But i hate too put the old cams and bearings back in...Since they get the most wear than any other part in the engine by dry starts.

 

You can get some good cams from Isky (search the web, you'll find them) for about $200. I think they do regrinds, so you may have to send yours. I have a spare set I'd sell for the right amount of money if you need some.

As for the wear of cams... You will likely see more difference in replacing lifters than you would the cam. That's because as lifters get old, they leak more an more, begin to tick, and actually don't open the valves as far as they did before.

oh, and there are no cam bearings, the cam rides directly on the machined aluminum surface of the head. Usually wear here is not a problem.

 

How much do u want for them?

 

I dunno...make me a fair offer..
