Not 3K ....5-6K on a petrol is fine......the diesel needs doing more often mainly due to the soot that gets into the oil past the bores.

[tunnie]

also oil in a diesel, its first job is to clean, so its not engine ware that uses oil so fast, its the soot in the oil  

[motmann]

bmw engine ok , timing chain bit of a nightmare to do, sump off etc, vauxhall did a recall on m&n reg diesel omegas (on the chain).....oh try and get something like an exhaust system for a later 2.2 facelift!!!quite a rare beast by vauxhall standards ask any dealer parts dept!

The BMW M51 2.5TDS is the motor fitted in most diesel Omegas up to 2001 (there was a rare 2.0DTi unit as well).

Its a fairly smooth unit, but underpowered due to detuning to stop it wrecking autoboxes. Easy to rechip to BMW spec (see Omegatoy), but if you have an auto, it will destroy it.

Oddly, I have done an awful lot of research into this engine, and have to agree with Marks_DTM about its ruggedness.  Yes, there are examples of high mileage ones, but there are lots of examples of scrapped ones.

Cooling seems to be a huge issue with this power plant.  And cooling issues on BMW engines warp and crack heads easily.  My own tractor seems like it had an issue with the oil jets to the pistons (cured by some of Omegatoy's magic potions - I ask no questions!), but the overheating that this lack of piston cooling caused wrecked the head.  I suspect similar piston cooling may be the cause of the ones throwing rods etc.

I think the lack of oil cooling to pistons is related to the utterly ridiculous service interval of 4,500 miles!  Now, you buy a diesel because you want to cover a lot of miles (else it is not cost effective), yet you have to get it serviced every 3 months MAX.  I suspect most get done much less regular, hence the expensive damage.  Using longer life oil won't help either, as its the particulates in the oil, rather than the oil breaking down (as in petrols) that are the reason for short service inteval.

Tend to agree with most of this, all I know is I used to drive, and still have it, a BMW 325 TDSE, goes like ... well all I can say its on Par with my MV6 up to 80 Mph, and still returns 36 to 50 Mpg!

I got involved with Megy's in 2005 coz I needed a Estate, It really was a tos up between an Meg 2.5td and a BM 525 Estate (based on my 325 TD experience), the Omega won on price, but what a difference on performance.... Ok there heavy Buses, but they really just dont perform either on performance or MPG.

Once I get the Bank Balance sorted after Xmas, Im going for Omegatoys 2.5 TD Chips and see what that doe's, If it come's anything close to BMW 325 performance but more inportant MPG I'll be happy, otherwise I'll stick stick to my 3.0 MV6 Estate untill such time I can afford BM or (hate to say this) Audi Estate Diesel Estate for work.

(Still keep the MV6 Estate though, love it!)

2.2 chain drive lomng service intervals exhaust parts no problem they are all the same on the diesels fuel and oil filters a bit fiddly but bags of power (i tow my holiday box and it does not know its there ) hope this helps

[Marks DTM Calib]

I was going to say.....2.2 diesel exhausts are no problem to gt hold of....and they are on trade club.

[eomega]

thanks for all the input lads,  would i be better comming up in the years and going for the 2.2d?   would it be better mpg?

I have a question though!
Is there something that can be done to lessen the risk of engine failure as a result of a lack of oil to the pistons?
If so Mr Omegatoy, what do you have brewing in your cauldron?

Without question better MPG. Obviously it depends on how you drive it but honestly never seen it drop below 40 solo minimum 42 and as much as 48.

With the newer engine you will also be getting a much newer facelifted, revised, hopefully unrusty car and given their superb value for money anyway, I think it makes sense. Now the problem is trying to find a low mileage diesel!

Good luck

very regular oilchanges and if you are late with one or two then a super strong flush, (unfortunately its trade only the stuff i use) thats all it takes
i look after 2 others and a range rover with the same engine that have all done well over 2hundred k and are absolutely fine
as to the other question about 2.2 or 2.5 the 2.5 is smoother longer lasting and i regularly get 48 to the gallon and have a lot more performance than the 2.2, but its horses for courses i guess
Omegatoy,

[JamesV6CDX]

I recommend 3k oil changes on anything...

Regular (ie, 3k) oil changes.

Omegatoy,

Thanks
As I have my servicing done by someone in the trade, could you say what the product is (PM if necessary) & I'll get him to use it?
