Howzit team, just after some advice if I can. I have slight oil leak coming from one of the small holes underneath the rear housings exhaust port, is this something I should be concerned about/is this normal? This engine is an S5 turbo block that has been recently rebuilt (yet to be fired) with all new soft and hard seals.

 

Oil doesn't make it there at all i believe, if its rebuilt and not fired yet, your just seeing assembly oil

 

Yep, just assembly lube.

 

That's what I was thinking, I sat there racking my brains for what seemed like an age looking at an old housing trying to figure out where it came from. On second thoughts it could and probably is the oil I put in the spark plug holes to aid with building compression?
So I should be safe to fire this mother up??

 

Cheers for the reply Aaron.

 

All depends on who's mother you want to fire up......

But in this case, yes, install and hope for a turn key start

 

Any mother will do
Engine is already in and has been for a month or so, only reason I haven't started it is I had a few electrical gremlins to deal with among other things. I only noticed as I was under the car running new fuel lines and saw oil seeping from the exhaust manifold, I originally thought it was my turbo oil return line.
