Honda-SOHC

Hi everyone,

I recently noted the my oil pressure light is coming on. As soon as I start the engine from cold, the light goes off, but then it goes back on as the engine warms up. When I rev the engine, the light goes off as well? Doesn't make sense in as the oil would be easier to pump at high temps as it becomes less viscous and if there's blockages I'd assume the light would just stay on?

I think it's the original pressure switch and seemed to work OK, and I've checked the wiring and this also seems to be OK.

If I crank the engine with the switch removed I can see oil coming out from the port the switch is installed. I've not removed the tappet covers but have taken the cylinder head side covers - there are signs of oil on the o-rings, but it's not spilling out the holes when the engine is running.

I'll probably buy a new switch, change the oil and filter, clean the mesh at the same time as a starting point. But any advice on what else to consider?

Thanks Bryan.

Mirsubishi on the L200 stated you could use up to 25% petrol in the diesel

Could be worse.... one of the drivers at work put unleaded in his truck. 50 litres of the stuff mixed with 50 litres of diesel.  The bill to drain, clean and flush.....£3000.

Had he run the thing any distance, then the fuel pump and injector seals suffer, and that would push the bill north of £10k. Luckily he realised what he had done and didn;t just sert off on his delivery run.

I did it with the VFR. I didn't even know until I pulled out from the forecourt onto the main road and it died. I pushed it the two miles home and drained 15ltrs of diesel into three jerry cans and gave them to my neighbour for his van. I had to replace the fuel filter in order to be able to start the bike.
