What is your oil pressure @ 4-5000rpm! When Warm (UPDATE 6/4/07!)

I really need to find out if im looking into a problem that doesn't exist...as the title says...what does yours read once your car is at its normal operating temp?

I'm getting distressed!

Thanks for your help in advance!

 

If worried about oil pressure, you shouldn't be running at 6k, surely?

VAG spec on most engines is 2bar @ 2000rpm hot

4+ bar you should be seeing at higher revs I would say.

 

To add to what GVK said
This what I observed when I added the turbo to the oil circuit.
G60 pump housing and ABF oil gears
First start up cold at 1800revs 5bar
900r/min 1-1.1bar@100degC
2000r/min 2.5bar @90degC
3500r/min 3.7bar@90degC
4000r/min 4.5bar@80degC
Stays pegged at 4.5bar 4500+

 

just a guess...no rev counter!

 

Christ knows whats cauing this high figure then...ive so far changed, oil pump, filter, removed pressure relief valve from oil filter housing.. (checked to see if moves freely) still sky high.

 

What's it reading Mike? What car too?

 

my mk1 18T agu....goes off the scale...had it checked again at gms and was reading 175psi

Above...some of the things I have checked/changed!

 

have you compared the gauge reading from the other car? that is a huge amount of presure for a stock pump to be producing. have you changed anything that could affect the pump, pump drive etc?. sorry im not that familiar with the 1.8t engines.

you could try the pump from the leon in the golf

 

I have replaced the pump on the golf for a working on and checked the pressure relief valve to make sure it moved freely which it did...on both pumps old and new. Good idea to check the pressure on the leon tho aswell as a comparison, thanks for your ideas! This is driving me insane!

 

Have you checked the sensor matches the gauge?

 

mine is a capillary guage and the ones at the garage i use are also a professional set....

 

Strange thing is I’ve see oil filter blow apart at a lesser pressure than that when the pressure relief valve has stuck

Does the oil filter look swollen at all?? And what’s the pressure when cold at rpm??

 

shows around 100-120 psi when cold at idle

 

Yikes!

It's a wonder the rear main stays in!

 

have you actually taken the front filter housing off of the block? perhaps the gallery to the valve is blocked inside? if you`ve got a small compressor handy just try blowing through the galleries.

saying that, why don`t you just stick an ITB 2.0 in it, you know it`ll be less hassle

 

i'm coming up tomorrow....i've gotta get it sorted!

 

There’s got to be something wrong with either one of the pressure gauges or the way it’s been tested, the pressure/rpm cold will always be more than pressure/rpm when hot because of the change in viscosity of the oil.

strange one

 

I checked the oil pressure on a 16v polo today and that went right of the scale,its got a rattly top end even after fitting 16 new tappets

 

Found the problem (well gms did) ! Actually no problem with oil pressure...measuring it in the wrong place...this is before the pressure relief valve in the filter housing. I have now tapped it in after...this is where the stock oil pressure switch sits....silly putting it anywhere else really, just assumed that all tappings on the filter housing where the same....



Thinking this is the place to measure the crank shaft oil pressure...

Anyway, i'm happier now! Doesnt explain the smoke tho sadly...possible turbo seals

Thanks for your help guys....

 

i was gonna mention you might have it in the wrong'un, oh well, its done now, you best get it out on track init,
