I TOOK OFF ON THE FREEWAY for about 5 k's and when i got off my right side head was making a really load tappety noise (louder than usual) quite loud actually. its a 1800 bay kombi.
why do they always break down just before dubs by the pub.

tappets???

i take it , it has solids not hydraulics???

Start with setting the valves

there is also smoke coming from the breather hose from the case, is that normal?

depends - a light mist is ok.

Smoke machine impersinations is not good

THE NOISE TURNED out to be a gasket from my new exhaust blowing out. it is 2 months old and desitegrated in my hands when i removed it.
