Oil Pressure issues

[A80Avant]

i cleaned the contacts and cannot say i saw any difference

in my case, my oil pressure @ 75C coolant temperature is 2.5bar on idle and at 81C is 1.5 to 1.8bar. Then if the car stays at 83-85C when the coolant fans kick in, it will go to 1.3bar and later on to even 1.1bar.

all lifters are new on my engine, so i still believe its normal. I have >2bar from 1500rpm anyway

i will be changing the sender once the break in of the engine is complete and put in a new filter and just wont worry about it.

IMHO you should also change cranks main bearings not only rod bearings. And I don't think that lifters could cause oil pressure dropdowns.

Just to make you all feel a bit better, went on a trip 2 weeks ago with amongst the cars a new 997.2 GT3.... oilpressure at warm idle = 1 bar

In relation to gauge accuracy i watched my 7A slowly drop from 2bar down to 1.5bar over a few years, then the sensor went faulty and wouldn't register anything below 1.5bar. Fitted a second hand sensor and it went back to 2bar. Basically take the pressure reading with a pinch of salt. Idle speed also effects your reading, a hundred rpms will make all the difference.

If anyone is interested i opened one up to see how they work --> http://www.s2forum.com/forum/showthr...t=oil+pressure

How is the sender best accessible? Do you have to remove the radiator, or his the fan? Best from the top, or bottom?

Had a look today and its not the easiest thing from the top

You need to have a really flexible hand.

I changed the lower sensor recently and pulled the radiator to do it. To get the fan off you need to lift the radiator to get at the bolts, so at that point i just dumped the coolant into a bucket and removed the radiator, made life much easier. It might be possible to change the upper sensor by lifting the PAS pump up and reaching in, a double joined arm would be needed.

From memory the only angle you can get a spanner on it is from the rear, would defo help with the rad out the way. I'm sure its possible without though, on an ABY / ADU with the slimline rad shroud.

I made a "special" tool for it..
my English are not so well , so I can't discribe you ..
tomorrow i will post a picture

what i am afraid of is the possibility of removing this one and then not being able to properly bolt the other one in to tighten it.

Looks like the aux water pump is in the way when trying to reach it from the back.

Today messured my ABY's oil pressure and it seems that I've everything tiptop with gauge readings.

how many kms do you have?

[Thuppu]

Max, quite high idle rpm's on warm engine..?

[terrybullwon]

So what's the spanner size on the oil gauge sender?

[A80Avant]

that indeed. at 1100rpm i bet mine is near 1.8bar

my idle on the dash sits just below the 1000mark and vems reads it at between 910-940rpm when the engine is really hot.
