My 205GTI seems to be low on oil pressure although the oil level is good. It is in between the first and second oil indicator markings on the gauge (on the LHS of the gauge). I presume this indicates low pressure and the RHS red end is high (and not detonation level!)
My car has had an english 1.9 engine transplant and the engine appears healthy. I run castrol magnatec, it doesn't burn any oil and there is only a slight bearing rattle when it's cold for a couple of seconds. Do these cars have a reputation for bad oil pumps? Any ideas re gauge / oil switch / pump??
