Ok.. finally got my fresh engine rebuild (new pistons liners etc done by cgb) into my car.
I got it fired up.. and ran it upto temp .. fan kicks in .. oil is good.. no missfires no white smoke.. mint!!!..
however
shock.. oil in the bottle , and a lot of it..
Engine oil seems minty fresh as does the underside of the rocker cover. Im thinking it may be rubbish in the lines or similar.. (at least im hoping that).
Ive cleaned the header tank oil and will refit and rerun tomorrow to see if it returns.. I didnt flush the cooling system etc so maybe i should have.
Any thoughts and opinions before tomorrow.
