I'm fairly certain a coolant seal has blown in my turbo s5 13b engine that I just rebuilt. I just started the car the other day and as the engine is reved up and builds boost the engine begins to overheat and steams begins to shoot out of coolant hose connection. I'm almost certain it's a bad coolant seal, possibly in the intake chamber area but would like to know what you guys think? and also my main question is how should I repair this? The engine was rebuilt by me to begin with because of a coolant seal failure. I rebuilt the engine, broke it in and got a few 100 miles or so out of it before this began. I might have over looked a break in the coolant seal lip but if not could a warped housing keep causing this or just a bad coolant seal itself?
Thanks, Joe

 

Won't know until you pull it back apart

 

^True.

OP, are you placing the coolant seal seam (on the pink seal) between 9 and 12 o'clock? Guys, correct me if I'm remembering wrong.
