Hi all, I have recently got my hatchback back on the road after several years of storage. It runs a black 308 out of a VK, L34 style heads etc. I have noticed that when its sitting in my driveway which has a very slight incline the oil pressure gauge ( factory ss cluster) indicates good pressure but on the flat road it reads no pressure. Oil level all good. Any ideas? Thanks in advance Jayson

Thanks Steve, will try your suggestions. I don't think it is anything serious as all seems good, it may even be a cluster issue? Just concerning when gauge does weird things. Car in driveway( slight incline) and idling has good pressure on gauge, but drops away to nothing when on the flat road.
Jayson.

Would also be worth getting a 10 ohm resistor, this will let you check full scale on the gauge, Oil, Water and Fuel all use the same resistance for low and full on the gauge.
If you put a 10 ohm resistor in place of the sender your oil pressure gauge should show full.

Thanks Mick I will add that check to the list. Jayson.

also a thicker grade of oil , may make a difference as well, as i had low psi on idle , using a thicker oil sorted the problem , i just make extra sure i am at operating temp before i put the boot in ,
just a thought, wazza
