Hi,
My brother has a Golf 1.8 Driver 1991 model and just recently it has started making a loud ticking noise on startup which goes away after you give it a small rev and doesn't come back..
Oil pressure is fine, the light goes out straight away when starting..
I initially would have thought it was a big end knock but then I would have expected it to always be there and not to go away after the first rev..
Do these models have hydraulic lifters? Could one be sticking or maybe worn?
Would a thicker oil help?
Thanks
