Hi guys, I've got a 1985 3.5 LPG 90 and I took my 90 to the garage recently and since then this yellow gungey stuff has been coming up into the air filter - offenhauser head- and was just wondering what this generally indicates?? Cheers

problems!! it sounds like a mix of water and oil usually from a busted head gasket .having said that it is more commonly found under the rocker/valve cover. have you checked yer oil since you got it back?
