First proper trackday for 3(?) years at Loheac on Friday. I installed my spare engine for the day after I had skimmed the block to eliminate frequent head gasket problems. The only other work that I did on it was to replace one oil control ring which I managed to break during reassembly (oh, and all new bearings of course) The car ran very well and I genuinely surprised myself with my eventual speed after such a long layoff. A really enjoyable day.
However, the day ended when my oil pressure soared ( nearly 100 psi at one point). It flickered back to normal and was obviously the pressure relief valve sticking. I'm told that this occasionally happens with vx engines but I've never experienced it before. To add to that, my low pressure warning light flickered on occasion (there are some very tight corners). Pressure returned to normal and no nasty noises. I did have to top up the oil more than I expected although I could have underfilled it at home ....not sure ....
Taking the car off the trailer revealed a significant (engine) oil patch on the floor. Changing the oil pump is a no brainier which I can do with the engine in the car, but to check/replace rear crank seal is engine out.
Convince me that it's not necessary ..... (if you can)
