VW T5.1 excessive oil use

[hoddy]

Ok, I've got a plan.
2010 5.1 is leaking oil due to engine damage from EGR. Engine still runs well but comes up with fault codes / limp mode etc.
First step - prevent further damage
----> gut the DPF, blank the EGR, remap ECU and maybe a performance tune for a bit of power.
Second step - oil change maybe with a thicker oil to prevent excessive oil loss.
Third step - maybe can live with oil loss as long as engine still ok. If engine gets worse then I'd need a new engine but would not need DPF or EGR replaced as these would have already been dealt with.
Booked to have it done next Friday.

I spoke to a German mechanic the other day he specializes in VW AUdi BMW Mercs only , I broached him about EGR blanking DPF etc . He was very knowledgeable about possible problems that may occur down the track after around 20 to 30thou km after the mods are done . Apparently the EGR and its cooler is designed to keep the engine operating temp in a very defined range , without the EGR that will change and over time can lead to piston failure .

I would have thought it would run cooler, which is a good thing for Australian climate. And s free flowing exhaust can only be a good thing as well.
Given the engine I've got already has cylinder wear, and the DPF might not be in great shape neither, so I don't there's a lot to lose.

You can only work with that is in front of you, its worth a shot.

I had a older tractor and it needed new rings, but of course they were as rare as unicorn ****, and i wasn't able to source them anywhere

so i just used a heavier oil and it did the job.

Update:
Van has been getting worse last 2 weeks. DPF light coming on all the time, and going into limp mode quite a bit. Have been able to clear fault codes while driving using the VCDS, which is good for taking off from lights, going uphill etc.
But still bloody annoying.
Rather than a new engine have decided to gut DPF and blank EGR.
Just picked up the van from having this done. I also opted for a REMAP as well - why not - the engine needs replacing according to VW.

WOW - the van is punchy lively and has more power than when it was new! Am stoked.

Next step is to flush the oil out, along with the ferrous / silicon / crap from the corroded EGR.

Will change to a thicker oil - liquimoly 10W40 - which might reduce some of the oil consumption (was 1litre per 1000).

Will see how this existing motor goes - might still last some time.

How much approx. ?

[Bryn23]

awesome, hope you get more km out of the engine.

New oil will help, but interesting to see if does reduce the oil consumption.

would running a engine flush agent in the existing oil, help before new oil?

How much approx. ?

It was $1300 quoted. But negotiated a bit less.
Includes: Gutting of DPF, blanking EGR, software deleting, Remap/ tune.

Given VW quoted over 17 K for new engine / DPF / sundries I reckon it's a no- brainer.

Local mechanic is going to sell me 20Litres oil, filter, and stuff to put in old oil before change. Apparently u let it idle for 10 mins with this stuff in, and then drain.

Sounds like a great plan, that should help clear out the crap in the current oil.

All up, its a risk worth taking, considering the cost of a new engine... i still can't get my head around $17k
