TD5Inside advised me not to run thicker oil because it will put the oil pump under too much strain.

Oil consumption?
Low power?
High fuel consumption?
Oil dilution?

If all else is normal I would do nothing, but fit a Provent, run fully sythetic oil which evaporates less easily and drive it.

Don't waste your money trying to fix a problem if you don't really have one.

Oil consumption? 2 liters in 2 weeks approx 2000k'ms including a 100km low range 4WD weekend. I checked the oil when i got home from the trip and put 2 litres in it.

Low power? - Couldn't tell you I've got nothing to compare against. I recently blocked the EGR and it has made a significant difference to the throttle response.

High fuel consumption? - Difficult to be sure as my MAF failed about the same time so i'm using more fuel anyway.

Oil dilution? With what? No water in oil. But I put 8 litres of Magnatec 10W40 in it about 2 weeks ago along with 2 new oil filters. When I checked the oil after the trip it was black. **Interesting note my car was not blowing any smoke. Even when I pushed it flat out up a hill on the way home.**

Hmm..not normal of course!

I hope you get to the bottom of it and find a non expensive solution eg a good secondhand complete engine or a bargain complete disco.

Yes and no! You would be wise to use your 2000 injectors in the EU3 head and your cam then it would be fine and you wouldn't have to mess around with injector codes. Any problems doing that anyone?

Jazzman, you won't really know until you pop the head, it might be as simple as a broken piston ring or stuck oil rings.

Oil dilution with diesel.
The injectors have an oring seal & copper washer on each injector, if corrupt can pass diesel into the oil thinning it out...

This can happen with a crack in the head as the early engine/head has 2 internal fuel galleries, but would think your oil level would rise if this were the case.
I had raw diesel in the coolant from this.

check the dipstick & see if the oil looks watery/unusually thin, or a diesel smell to it

This is interesting. The oil did seem kind of thin and black on the dip stick. But can't be sure. The 20W50 didn't look thin after about 200kms. I'll check the injectors.

I removed everything from the motor today, intake, exhaust ect. The head has been loosened so has the timing chain and top gear.

The engine crane is setup so tomorrow i can take the head off straight away.

I decided to let the bloke who bought the head off the bottom end i was going to by also by the bottom end as well so he had a pair.

I'm just going to rebuild the motor I have, it will cost more or less the same. Thanks for your advice though, much appreciated.

So next phase. Cylinders 1 and 5 have a lip on the top, larger on the front than the rear. Not sure of the measurements exactly but enough to catch your finger nail on.

Is this common?

I can't work out why this motor appeared to be functioning fine for 280,000kms then at 295,000kms have bad blow by and use oil.
