i think we got of the thread Ryan(gorto) was talking about K&N air filters no matter....
Gonedeaf are you reffering to the original holden oil pressure gauge..always thought they were a little hard to read thats why i put a VDO one in mine
Yep sure am.
My 308 reads the same as yours. I have the original gauges and use a Ryco oil filter. My old hatch with the 253 was the nearly the same but read slightly lower as the motor was getting tired and has not been rebuilt.
Thats good mate sounds like it is working normally then 
After a hard charge through the first three gears a long heavy brake stop would usually make the engine oil warning light flicker for a sec or so. Never came to any grief, spoke to Izzy at COME and he said the oil pressure used to drop to nothing for a few secs at the end of an 8 sec quarter with the 383 Holden in the little yellow COME1 Torana. He never found any oil wear related issues when it was pulled down after lots of runs.
Yeah thats exactly whats my oil pressure is doing rexy although I havent seen any warning lights come up.
Sorry, my mistake.
I said air filter, but i men't OIL filter.
I didnt read air filter as well lol.
Cheers guys for all your help.
