Ok, I've got an 87 Turbo Coupe with an Automatic. Knowing that, you would assume that I would be getting about 10psi of boost. I'm not.
For the past 6 months that I've owned this car, I've gotten at Most 6psi.
I've checked all the hoses, and none appear cracked. The IC hoses are not split, and all the Clamps are tight.
Two days ago I had a new Catalytic converter installed, but that did not change anything.
Today, I spliced together the two hoses that go the the BCS and the net gain of boost was a whopping 1psi!
I am left thinking that either:
A)The car has 200+k miles on it, and the turbo needs to be replaced
B)The Wastegate has some sort of problem which I don't know how to diagnose
or
C) I've been getting 10psi this whole time, but the stock gauge isn't reading correctly for some reason.
I'm leaning towards (B) simply because everyone seems to point to that as being the leading cause of boost lossage. Problem is, I have no idea how to check it and It's in a very awkward area to get to, and I really don't enjoy those 2nd degree burns from the exhaust.
Any other ideas? Suggestions on how to check the Wastegate? Pictures?
Thanks
