wastegate flap seal?
 

hey all, does anyone know how well the wastegate flap/penny should seal/seat on the turbo housing?? does it need to seat 100% perfect or would you expect to be able to see a hairline amount of light with a torch shone on it?

I would expect that a small gap could be considered normal.

Ideally it would be a perfect fit, but should work o.k. IMHO

dunx

thats what i would think but not sure, it came off a car that was working fine

bump

I fitted a new one recently and ground it in like you would a valve. Fussy bugger though

how easy was that to do?

Drill with forward and reverse and some grinding paste.
