Where is the PCV valve located on the 1990 Reatta?

It's probably staring me in the face, but I can't find it.

Not sure on a 90, but on a 88 it's buried on the top of the intake manifold behind the belt tensioner. For easier access you might consider taking off the belt, removing the bolt that connects the alternator and power steering pump, loosen or removing their remainng attachment bolts and then pivot them out of the way.

You might also consider replacing the pvc grommets as well, the one in the intake mainifold can break and drop into the manifold, so be careful

FWIW I'v had a couple of folks tell me of problems caused by new non acdelco pvc valves, when replaced with a acdelco valve the problems went away, not sure of the problem valves brands.

If you do move the alternator and power steering pump it would also be a good time to replace the small bypass cooling hose
