  1. Changed the oil in my vitesse . Engine fired ok , no oil pressure . Light on and no reading on oil pressure gauge . Stopped engine after about 10 secs and looking what to do to be safe . Pressure gauge is on a T with the oily pressure switch . Normally get reading after say 5 secs with pressure reading at 70 going down to 45 to 50 when hot and cruising at 50mph ish . On tickover when hot about 20 to 25 . Any advice welcomed Paul
  2. Hopefully someone can advise. I have read up on this and the suggestions range from "don't worry about it" to "rebuild the engine"! Herald 13/60 When starting from cold the idle oil pressure is around 30 PSI, which seems to be about correct. As the engine gets hotter the idle oil pressure drops. Eventually reaching 0 PSI if stuck in traffic. At 3000 revs it's always 35+ PSI whether hot or cold, it's only the PSI at idle that changes. The car is not losing oil and runs fine. I have recently changed the oil which has made no difference. I am using "Comma CLA20505L 5L 20W/50 Classic Motor Oil" (this was recommended somewhere, but can't remember where). So my first thought is the oil itself, getting too thin when hot. Any recommendations? Second thought would be the oil pump, but I'd rather not change that if it doesn't need it. Are these symptoms a problem anyway? Thanks in advance.
