Ok so my friend is finishing the rebuild on my S3/S4/S5 turbo hybrid motor for my first gen. Heres my question. On the TII rotor housings above the exhaust ports there is a hole that is open for oil flow in a turbo engine well I need thoses closed anyone know where I can get plugs to fit that?

I got a picture of the holes I'm talking about attached... where do I find these plugs or do I just devcon them in?

thats actaully for coolant im guessing your not using the turbo intake. well many people tap it and get plugs from your local hardware place. does anyone know if that just runs though the manifold? and back into the other housing. and does the center iron have an a waterjacket or must it run though the manifold? sorry for stealing that

yeah coolant... not oil... god what the hell was I thinking...

ok so I got super lucky and found some freeze out plugs at autozone. Whats better is that they were discontinued so I got them a .01 a piece. I just hope they fit. I got a few different sizes just incase.

Coolant goes thru that hole to the turbo and out the turbo thru a line that connects to the bottom of the water pump. The other rotor housing has no water hole. That is for Phantom

Hailers...you ok today???

Coolant actually comes out of the rear aluminum housing and goes into the LIM. From the LIM, it flows into the coolant inlet tube for the turbo.

The front housing actually does have the hole there too. But there is no passage into the LIM. There is still an o-ring on the front housing hole, but the LIM does not have the passage, so the coolant is blocked.
