Just a little update, valve cover gasket was done on Wednesday and that was the problem. Because car stood for a year, the gasket got weak by the looks of it. But good news is seems all is ok at the moment, besides finding some shoddy workmanship from the previous guys that worked on car.
So over the weekend played a bit and sprayed rims and did some tyre lettering and smoked taillights and sprayed calipers.
Gonna give car a week and check that all ok and then gonna do exhaust and have you got experience with the boomba bov?
