Last night my oil pressure started to go a bit loopy. If I was driving along normally the pressure would sometimes go down to 2.5 bar or something. Another example is that I was doing about 80mph at about 4krpm and the pressure dropped down to 2 bar! I was a bit like .
I suppose it does sound like the pressure valve thing sticking (so much for SBD's nylon one to not stick ) so would I just need to take it out and spray some carb cleaner up the hole that it comes out of to clear any muck away?!?
