Technical GP T-Jet Oil Consumption

After a weeks usage the oils dropped down to about 3/4 on the dipstick. Not as much as before, but still more than I'd like. Will actually have time to do the oil change tomorrow.

Can anyone recommend how I take out the current oil filter? Its in a really awkward position underneath the air intake/turbo. I'm thinking of taking the intake off.
I have the same issue as you i cleand the pcv and i found finally that the cold side of the turbo is leaking oil

Thanks for the reply,

I feel like if the oil was leaking, I would have seen it by now. At the rate its been going through it, and over the period of time, I would have noticed a leak, surely?
 
Well, I found a leak. Disregard previous reply of me looking like a spoon.

During the process of changing the oil, I noticed a few small drips of oil around the backside of the the unit where the Oil Filter is housed. I just presumed that it was residual oil from where the old one had been taken out and originally thought nothing of it.

I let the oil settle, take her for a spin up the shops, come back home and see that there are a few drops under the car, tiny, drops. Again, I think its just from where the filter was off, but I think, let me check, just incase. So I wipe it down, run the engine for a bit and what do you know? More drops.

Keep wiping it down, and drops keep coming. Although they were getting fewer and further in between, but still drops. I then take a look at the underside plate thing that screws in, and on the side under this unit, the foam thing is darker than the other side, and has a layer of what looks to be oil, sort of dried. It is not 100% definite oil as I stunk of the stuff, but it seemed like it.

I can't see where the leak is originating from, but I presume that this is my issue. Can't believe I hadn't noticed it before.

Images attached if anyone can make sense of it. Ive for the 75k service coming up/MOT so will get them to have a look at it, in the mean time, I'm stumped. On the second image its more noticeable, you can see the small build up of oil in the center-left, that drips down.

Can't quite tell from the picture but it looks as though the oil may be leaking from the oil cooler... perhaps where it mounts to the engine block... I've never had one off before, but maybe there's a worn seal in between the block and oil cooler. I can't imagine it being a huge job to take off and replace the seal, but it might be worth looking into and researching. The oil cooler and the oil filter housing are all one component I think. Let us know how you get on
 
Will do, and thanks.

I was working on it with my dad, and his immediate thought was exactly that. Will look into seeing if this is a job that I can do myself.
 
Is it easy to open the oil separator? And how can this be done without damaging it?

I think I have a problem with it. Oil usage is still very low but I had issues with a remap. After the remap (have 120 hp t-jet equipped with a Abarth 595 VL38) the ignition timing jumped from negative to positive all the time, till I restart the engine.

The tuner remapped the car again, suspecting the oil separator was different from the 155 hp versions. The 155 hp was used as a base map. Now the jumping in the timing is gone but I have continues negative spark advance in lower rpm till let's say 4000 rpm (with no detected knock). Above that spark advance is positive.

After the second fine-tuning I'm also missing torque and hp, a log with a pull in 3th gear from 1600-5800 confirms this. First with the jumping advance it was about 10,3 second, now around 11,7.

Could a bad oil separator cause this? The part number is exactly the same for all T-Jet engines I think, so that shouldn't influence the remap.
I'm now thinking of cleaning it, but don't how how to open it and/or the problems could be caused by this?

Can assume that it creates a sort of vacuum, which could cause a fault in the mixture and that the timing is correcting.

Haven't tried it myself, but the engine gets more guides in the 500 Abarth shell.

This might help out if it's the AOS.
