Hi all,

Just replaced my head (cracked) and gaskets, fluids, filters, etc. on my 2002 non-S and now the oil pressure light is on. It was flickering for a couple of days on acceleration (off when idle) but now it seems to stay on once the engine is warm. I've got a whole list of what it *could* be, so I'm starting at the cheapest and working up to the worst case scenario.

I disconnected the oil pressure switch, and the connector and switch has quite a bit of oil/fluid in it. I'll be picking up a new oil pressure switch on Monday, and was wondering if I need to drain the oil before I remove the old one?

Thanks

 

Let me answer my own question - you don't need to. After letting the engine cool, I removed the oil filter canister (letting it drain first), and then the oil pressure switch. Only lost a few drops of oil.

Turned out my low oil pressure light was due to a leaking oil pressure sensor. When diagnosing the light I disconnected the sensor to make sure the light would actually turn off (it did). I noticed quite a bit of oil in the connector itself, and there was no oil leaking on or around the sensor. Unscrewed the sensor and sure enough, it was leaking inside, which explains why the pressure was low to begin with.

Now on to diagnosing my lack of low-speed rad fan and power steering pump fan movement. Both have been replaced, but still no joy. The fuse is fine, but I'll replace it and the relay to see what happens.
