As seen in the Pictures Thread in chit chat, my oil lamp is on, brightly, at 1,200rpm... This probably isn't good. So, to prevent clogging up that thread, here's a new one!

I'm mid-way through swapping the valve and switch, so on the left is the old engine's valve, and on the right is the current engine's valve. The current engine's has a twisted and stretched spring, the old doesn't - but the old one's plunger is dirty, and the shaft is scored by the spring. Is that a problem? Could I swap plungers and pop the old spring and plug with the new plunger in?


The switches:

Left is new engine, right is old engine. The new engine's one is clearly older - or at least more bashed about!

Use the better spring and the better plunger.....

The stretched spring suggests a previous owner was looking for more oil pressure.......  not a good sign!  But try anyway!

Have you tried the switch yet?

The switch is the likely culprit.  When they fail they tend to start to indicate lack of oil pressure at progressively higher revs.  If you really had no oil pressure at 1200 RPM the engine would clatter and rattle like crazy and seize pretty quickly.

Right, I'll pop the oil pressure gauge in the glove box and fit it properly in the future

How tight should I do that up?
Face of plunger is lovely, so that's all fitted now:

So are you saying you still have no oil pressure?? Or is it just a picture of the gauge in the glovebox??

Well, that's my oil pressure back! Ignition on, oil lamp comes on. Crank it and it flickers, and as the engine catches it goes out. Pressure gauge showing a steady 20-30psi. (Picture below to prove this ). Driving about it springs up to 50psi, above 2krpm it's 60, above 3.5krpm about 70. I believe it was, therefore, the pressure switch!

Still, however, no power from 1000rpm to 1,500rpm, foot to the floor and there's just nothing! (Better than the 1000rpm flat spot it had before though!).

Local garage had some lovely motors in, on the right is a MASSIVE Chevy

Yeah..... but the second photo shows pressure - so both the gauge and the engine must work

When i did mine i found the low pressure valve had notches in it, i just filed then smooth, put decent oil in for once and all was ok, but within a week i had fitted an oil pressure gauge just to make sure, it maybe another worry gauge but cant have too much info.

glad yours is back working.
