i need some help with this one.

[redrocket90gst]

I have a 1990 eclipse gs turbo. it came with a 255 fuel pump, b&m fuel pressure regulator. other than that its pretty much all oem.
I installed a forced performance turbo manifold (uncoated). After having it on awhile it now leaks a black substance from around the gasket.
A week or so later i also installed a dejon intake pipe and the car didnt run right so i put the oem rubber pipe back on which is still on and it still hasnt been running right.
The idle is off and it boggs down and dies alot while driving.
It also leaks a dark substance from the turbo to manifold gasket and also on the top bolt in between both sides of the turbo. the bolt has the # 7 on it.
My final concern is the exhaust smokes when it idles for a while, but when i drive off all the smoke gets pushed out.
I need some advice on where to even start and what the problems may be. any info, tips, or suggestions would be greatly appreciated. I have big plans, but Im getting no where.

Regarding the idle/bogging/dying, I would say triple check the connections, hoses and clamps you touched when you originally attempted to install the Dejon pipe. I know the first few times I r&r'd my intake pipe, I either forgot to put the breather hoses back on the pipe (which caused a stumble at idle), forgot a vacuum hose or two, or forgot to clamp down the pipe to the turbo. This sounds about right, seeing as it ran good before you removed everything.

I don't know much about leak sources yet, but I do know there's a exhaust manifold bolt to the head that goes right near an oil passage. You may want to research this more, but I'd guess that since you r&r'd the manifold, there's a chance something didn't go back together right and that oil passage could be leaking through.

Hope that helps you diagnose your troubles
