For the past year or so my 90 has decided to pop the oil warning light on when its really warm, ie off roading and had some hammer.
I thought that this was due to the engine that was in it having either a slipped cam bearing or worn piston rings (used to blow a lot through the cyclone breather which is routed to atmosphere)
I changed the oil pressure gauge and it carried on so I rebuilt a total different known working engine. The only thing I used off my existing engine was the head.
And so it happened again however engine runs sweet fires up straight away ect. I used a real thin oil to start with I think it was 5 30 fully synthetic. It happened again however I had now fitted an oil pressure gauge which shows around 15-20psi when the light comes on. So I've changed the pressure switch again and also put some 20 50 oil in to see if that helps but that's the same. Could it be faulty wiring or am I missing something simple
