Thread: 300tdi oil pressure?

IIRC the book says 23psi hot @ idle (1.5 bar) but I reckon that was in a Pommy winter after only 10km running.

I only ever got around 15psi (1.1 bar) with brand new and correct clearance big ends and a new pressure relief valve spring in the oil pump.

If the idiot light on the dash isn't flashing you are fine, just remember a lot of 300Tdi's seem to require big end shells changed at around the 300,000km mark.

Thanks, I'll relax for now then.

with just 5L in the sump and pistons that slap in the bores a tdi will run sub 5psi pressures and well still run ? AND the rollers / rocker gear et al will still be okay on strip down.

Im with Rick, oil pressure is a feel good measurement.

If the light is not on she will be right!

Having said that I have a VDO oil pressure gauge to fill in the hole where the clock was!

EMS pressure measures boost for moi!

Another vote for the oil pressure gauge to replace the clock. I must have put the gauge in at least 9 years ago now and have been scratching my head over oil pressure ever since. In '09 I gave it new oil pump rotors and relief valve spring and piston, last year in went some big end shells. Even running 20w60 the oil drops to a little over 10 psi at idle and relieves at a little over 30 after a vigourous highway run. Either the VDO gauge reads low or that's just how it is. Either way it's still going fine and certainly hasn't gotten any worse.

I pulled my mechanical oil pressure gauge out, I was sick of the paranoia !
