After a c oouple of issues with water flow around engine and spiking temp guage I am starting to think I may have a head gasket issue .

Anyway this may or may not be related or in fact nothing at all ..

I pulled the Crank case breather from the bottom of the air pipe it goes into just after the MAF .

and it is chuffing away , nowe I didnt think this was normal??
could someone enlighten me
