engine and drivetrain Orange "O" light comes on at idle after driving a

[Guest Anonymous]

since I installed my rebuilt head and 5 spd tranny, I have noticed that my Dash's orange "O" - assume it means OIL - comes on when I let go of the gas when the RPMs drop. The engine still runs solid and seems okay but the light is worrying me. Is it an oil pressure issue?

Any help would be appreciated.

Thanks in advance

just the sender! They commonly fail. I keep one in my trunk just in case :-)

Since the oil pressure light is coming on - that means you could be DAMAGING your ENGINE...so treat it with immediate respect!!!

The oil pressure switch is on the back of the cylinder head, and may have gotten damaged, or have a loose wire causing the flickering light...check it first before panicking.

If it's bad - they're under $9.00 or so...and well worth it for peace of mind!!!

Worst case scenario - you need an oil pump and should NOT drive the car until it's replaced!!!

or see exactly what is going on. The oil pressure light sender is very low pressure (5psi?) so, getting the gauge installed may tell you alittle more.

I usually buy and run a gauge each time I rebuild a motor and, then I wind up leaving it installed for the life of the car- doh!

Sako,

Now that you have a new head gasket, etc. and everything is all sealed up nice and tight, the weak link which is now the bottom end will show its angry face

Now would be a good time to pull the oil pan and pump, clean it, shim the chain, replace the pump if it the old style pump (with 3 M6 bolts holding the sprocket), and check and possibly replace the rod bearings. Not difficult of a job, just takes time and patience. If not your engine is gonna go

And NO, you do not need to raise the engine to remove the pan!

Email if you want step-by-step instructions regarding removal.

Parts list too?? I have a similar problem and my guage has verified low oil pressure after driving a while (over 20 minutes) and letting car idle. even tried the "old engine" oil. Same result.

She's parked in the garage until I can narrow the problem down! I really appreciate all your insights!

Back to work on her this weekend...

I read in one of the old roundels that you need a

minimum 10psi of oil pressure per 1000 rpms.

for the stock warning light switch...extra safety margin.
