Depends if any journal damage

I'd start by getting the sump off and seeing what is what.

Minimum new big end shells and oil pump, maximum new engine

as quoted. start with the cheap option first.

the big ed shells are designed to take the abuse first before the crank and con rods.

if the shells are still in the caps, whack some new ones in.

[Marks DTM Calib]

Why are 2.6s so prone to this?

Think about the recommended oil change intervals

[omegod]

Anyone know how much a set of big end shells are?

John is my cousin and I would like to help get him sorted out in any way poss, does the crank need to come out to replace the shells?

[Marks DTM Calib]

I think if anything, the oiling system on the V6 is its weakest feature.

I currently have 6 V6 Omegas and I'd sav that only one of them isn't in the early stages of big-end trouble. this is probably due to the high "normal" coolant temperature.

The oil pump was changed in 97.5 for a more chunky job with greater flow.

All bottom ends I have seen have been in superb nick, even at 200k + miles.

I suspect its more down to the oil change intervals and the fact that most Vx owners dont service their cars as well as they should or skimp on the oil.

And I dont agree with the coolant temp

how far did they extend it??

[CaptainZok]

It does make you wonder if we're now seeing the results of extended service intervals followed by poor servicing.
Makes you wonder if it's worth pulling the sump off and cleaning the pick up pipe on the next oil change.
The Gnome will be pleased when I tell him.

I'd certainly recommend this, going by my recent experience.  Apart from the slight possibility of causing an oil leak where there wasn't one before, I really can't see any downside.
In fact I'm planning to do this to my Golf on Saturday, as it's done even more miles than the Omega (178K approx).  Peace of mind requires it. 

Edit: And to John_R: big sympathy, hope it doesn't turn out to be terminal for the engine

This little spate of oil pressure related episodes makes me wonder if an oil pressure gauge would be a wise addition?

By the time the oil light is on it's too late - pressure is down to a few PSI, whereas if we're up against gradual blocking of the oil pickup strainer the tell tale signs would be there earlier on an oil pressure gauge. :-/

Prophylactic cleaning of the sump and strainer is probably an excellent idea, though, and probably negates the need for a gauge if the car is subsequently looked after.

I think these are the consequences of a 20k service interval starting to bite. It's also worth bearing in mind that with the introduction of that service interval came a requirement for higher spec. oil, and for annual changes if the 20K isn't reached.

20k service interval being applied, but with whatever cheap oil the garage has in their bulk container?

.. and another reminder that if the oil light comes on, the engine needs to stop immediately. A few seconds longer can kill it in this state, let alone a mile.

the top of a 2.6 has been succesfully mated to the bottom half of a 3.0

I wonder what compression ratio that engine ended up with?

Certainly lower!

Prophylactic: A preventive measure. The word comes from the Greek for "an advance guard,"

Also how the military refer to anti-malarials .. for some weird reason !!!

[aaronjb]

Wouldn't want to get the two mixed up.. I'd not like to try swallowing a condom.

Don't think it'd do much for malaria, either!

[John-R]

Thanks all.
I think the best way to go is to find a replacement and have it fitted.
I've been quoted anything from £1000 - £1800 for a local garage to source a 2.6 lump and fit it. Tempted as they also give a warranty.
Alternative is that I found a 2.6 from an insurance right-off rear end shunt - 56,000 and serviced with a 3 month warranty for £300 delivered.
Tempted to use this and get local garage to fit.

Darth Loo-Knee - my cousin spoke to you earlier today about this.
I'll call you tomorrow and discuss other options.
Thanks
