Hard to start

Asked by Harold Sinclair

I HAVE a 1982 VH Commodore with the 4.2-litre V8. I bought it new and it has done only 68,000km. It has always been hard to start, even though it has been regularly serviced and everything has been checked. It runs smoothly, has lots of power and is a dream to drive. I'm told there may be a problem with the inlet manifold leaking. Can you help?

LEAKING inlet manifolds were a constant problem with the post-exhaust emission V8 engines, but the manifold on your car was a new and much-improved one as part of the XT5 engine package. Though it's worth checking, it would normally result in a rough idle and possible oil leakage along the faces that mate to the heads. If your engine is running smoothly with no sign of roughness I'd look inside the carburettor and check the float height is correctly set. If your problem is cold-starting, adjust the choke two notches richer. That might be enough to fix it.
