My mk1 gti 1.8 had a recon head fitted about 7 months ago...its now started clicking when i put my foot down, its defo the head cos it does it when it in neutral also. I have a small oil leak from somewere but nothing major. I took the sump of and cleaned the oil pump gauze because i thought it might not be getting it to the head properly - its still doing it! Pls any ideas would be smashing PS - whats the best oil for a mk1 gti? Edited by: spider69er
