Low oil presure on idling.

[vwpro]

Won't it affect the firing on the dizzy?
I thought of a nother possibillity.
There is a presure valve in the filter housing as well, could that also cause low presure?

If it will efect the timing on a 2.0l then a 1.8l timing will also be out
Its very seldom that the pressure valve fails but something to look at, only problem you can't test it, have to replace the housing to see if its the problem.

I changed the housing and still the same.

divs between two shafts 2.0l on the left and 1.8l on the right, to do the conversion you use both the gears from the 1.8l and then trim the gear 2mm to clear the conrod like on second photo, if you technical then you can count the teeth and see the difference in speed between the 2 shafts, cant harm your motor because you have 2 safety protection valves, one at the pump and one in the filter housing, also don`t worry the teeth won`t break, many race cars run them like this with no failure at all, if you wonder why the 1.8l shaft setup gives you better flow and pressure when hot is because the 2.0l oil pump gears are lager than the 1.8l oil pump and you turn it faster





trim gear to clear 2.0l conrod

Ok my chance to have read the thing wrong. Thought he OP had a 1.8 bored to 2L. But seeing it IS a 2l then yes vwpro's soltion works.

Plaese help me understand this, my way of calculating this is that to get the pump run faster the dizzy will also run faster.
Won't it throw the timing out on the dizzy?
Cause the dizzy connects with a keyway to the pump which means it runs the same speed. So if the whole setup speeds up it will not run the same speed as the crank, thus throwing out the firing on specific combustion times.
Im just trying to understand this clearly so please explain it to me?

ok no having thought about it it will gain you nothing. The end ratio still means for one rotation of the engine the dissy makes one half turn. The pump is driven by the dissy shaft. So whether you use the 2l shaft and gear or the 1.8 shaft and gear the distibutor runs at the same rpm which is exactly half engine rpm. Sorry wessel i cannot understand the advantage.
The only setup that turns the pump faster is 16v where the actual drive gear for that shaft is smaller on the cambelt side but you cannot use that when you run a distributor in the block as the dissy to engine rpm will be out of step. If you use a distributor for anything timing related then dissy rpm must be equal to half engine rpm. Cannot be sped up or slowed down.

Sorry was not think clearly, the ones I did was with crank pickup 60-2 aftermarket trigger

Thanks guys.

Reading through this from the start, I am wondering if a 1.8 oil pump was not supplied and installed in the 2e block as the volume from a 1.8 is smaller than the volume from a 2L oil pump due to the shorter casing and gears. 6mm difference in height between the pumps. Bottom casing plate with the pressure relief valve where the oil pick up connects to is the same.

Thanks for the heads up!
Can any one tell me what make would be best?
Options i have is as follows.
Febi
Bilstein
Kolbinschmidt

KS or Bilstein is the better make, but any of the 3 will do.

[panic-mechanic]

febi and bilstein comes from the same factory. It's the same pump.

[VAG Fan]

That's what I thought, too. febi is actually an acronym for Ferdinand Bilstein, to my knowledge.

[panic-mechanic]

exactly that

Installed a KS and a better guage, now sitting at 1.8 to 2 bar on idling at normal temp.
Looks like a winning trial for now.
Thanks for your support guys.

Any pictures of the removed oil pump and its gears.

[corney]

Didn't take any pics, but it was infact a 2l pump. Just a poor make. Gears did measure 36mm though. Definately a differance in presures at the end of the day.
