Today my 86 turbo started knocking really loud. So, I popped the hood to have a peek. It was really difficult to keep running. But, I think I somewhat pinpointed the area of it's origin. It's knocking from the distributor. I pulled the cap off and had a look. But I didn't see anything "biting" inside the cap. Any other ideas? Or am I looking at having to replace the complete unit?

Pull the dizzy & inspect it. :D

Dizzy is good. However, now the car won't start at all now. I have a funny feeling I've got to pull the valve cover off and do a decent inspection under it.

did you check your oil????? is it a rAPID KNOCK OR IS IT SLOWER????oops....is your oil the correct color for the length of time it has been since your last oil change??? has the car used less oil than usual???is the noise variable in loudness on occasion???just make sure it does not pull a piglet on you....how many miles on your oil pump????if it is over 200k, change it. i didnot. i wish now i had.....

Dunno about the variable in loudness. It just started knocking really bad one morning. It didn't seem to get any louder or quieter. Just faster with the rpms.

As far as I know, it's the stock oil pump. But I was getting a solid 30psi of oil pressure when it was warm. And as I was cranking the motor, the oil pressure did start to build.

I just need to find more time to be able to further investigate this issue. But, with the way my schedule is as of lately, I don't see that happening for a while.

good luck, sugah----i hope the car works ok for you....

Oh the carnage! :wasted:
