Pajero Owners Club of South Africa

Hi Guys
My pajero has an amazing superpower!
It makes oil in the engine! How cool is that?!
Dipstick level continues to rise... have drained at least 6 litres already in 2000km and its still at full mark...
Here is what is confusing me... So if anyone can share some light...

At first I thought it was diesel leaking from pressure return system, but I smell no diesel in oil nor is it thinning or gritty.
Getting 13-14l per 100km with mods: lifted, 265 tires, roof rack, roof tent, heavy drawer system, rock sliders etc etc so doubting more and more that its diesel leaking.
Thought it could be head gasket leak, but coolant looks normal and oil is nice dark black with no muddy brown bubbles even when checked just after a drive...
The time it seems to rise is when I have the aircon on?! Just did a 1400km trip with no noticible rise in oil level but made sure to never run the aircon...(considering 3 times increase in previous 2000km, this is quite significant)
But since the aircon is in no way sharing any fluids with sump...?!?!!????

I do see quite a lot of condensation coming through the vents and actually wetting the dashboard when I have the aircon on...
Could it be possible that its causing condensation on the engine block and its water filling the sump?
I tested the oil I pulled by adding more clean water and it kept the same smell and consistency... But am still at a loss...?
Every time I check is first thing in the morning, on the same flat surface... And the rising of oil goes from full to above the twist in dipstick, which is over 3 times higher, so not a misread by myself...

HI I don't have an answer I would drain and change the filter. Is the oil dirty? Regard's Johan

Hi don't have an answer I would change oil and filter. Perhaps the oil is dirty and fin and somehow stays higher up on the dipstick. When did you notice for the 1st time. Perhaps somebody changed/swop your dipstick. Regards Johan

It's diesel - that is where my money is.

And if it is, then you are busy destroying your engine.

Car had new oil and new filter installed, so oil is new, Dipstick might of been changed, but still have the issue that I have drained it 4 times now, and each time it climbs to well above the full mark, even when drained to half way between low and full...
So something is certainly adding liquid to sump...

Roelf, that's what I thought as well, but if its diesel and has had over 6l added and had 6l drained, surely i'd smell the diesel and see a viscosity change by now?
Damage because of lack of viscosity or overfilling?

Next test is to take clean oil and add diesel and see if the smell and consistency is the same...
Strange how it is majorly noticable when aircon is used?

Does the fuel rail pressure increase under load or when aircon is on? Or is it always at a constant pressure when working?

Thanks

1) diesel from injectors will "wash" the oil off the cylinder walls, leading to wear.
2 ) rail pressure increases with load.

I am also saying diesel. Possibly from diesel pump itself.

I would not continue to drive it. Take oil that you drained for analysis. Bet you it has high diesel content. Then find the culprit and fix.

Thanks guys

Anyone know where I can get it analysed?

Being a 2004 3.2 DID that would be a Gen3. I am pretty certain we will find it is the seal on the pump that has failed. It does sometimes happen on Gen3 3.2's.

To do a check for the presence of a large amount of raw diesel in the engine oil, take a small drop of oil from the dipstick and put it on a clean piece of paper. Leave it for at least half a day a full day is preferable. If there is raw diesel present it makes a halo effect around the spot of oil. It works best when the oil is dirty. You will see it and understand immediately if there is raw diesel present. Take a picture and post it for everyone to see. it should be interesting.

You say the engine oil has been changed. It does not show quite as well with new / clean oil. Put a drop of new engine oil next to the used oil drop to be able to compare the two.
