Having taken my new 2.6CDX I bought from Simon to Penfolds for its annual service and plug change, the  helpful guys on the service desk gave me a list as long as my arm on "things that need doing" which amounted to more than the car cost!!  I knew that the disks at the front were pitted as it was an advisory on the MOT and I had ordered new disks and pads at £72 to be delivered Monday so I can fit them when we have a nice sunny day. I was not quite sure how the brake quote for the front got to £425 but it should take me 45 minutes per side, or at least that was how long it took me the last time!!

They said my oil pressure sensor had a "slight" leak (£180) and Kevin Wood says he thinks it is down by the crank pulley. Has anybody replaced theirs on a 2.6 V6 petrol and can advise me how to do it??

Before folks get agitated about my taking the car to a Main Dealer for a service, the car had a full Main Dealer service history when I bought it from Simon and I wanted the plugs done and a stamp in the book to keep the service history current.  I do not have the time at present to learn how to service a V6 which is a somewhat different box of tricks from my other 2.2CD "four pot"

trade club price for discs and pads you have there i think?

apart from that, you've answered your own questions i think? dont use a dealer. More than enough support on here, and discs and pads will be the same as your 2.2 anyway, and apart from grief with the cable tray changing plugs isnt far off either.

Any pics of the oil leak ? crank pulley seal is bit of a pig i gather...?

Slight leak from the oil pressure sensor is totally expected and just probably wants re-tightening. Look directly below the alternator and a bit to the right but still to the left of the large bottom crank pulley and you will see it and the sensor wiring in a sheathed cable protruding from it. Sounds like they have quoted for a new sensor. Fitting  is only a 5 minute job.

ah now thats differant, and i have that t shirt, suggest get your hand in behind the aux belt tensioner, big lump it is so youll need to contort a bit, feel for the back of the cam belt cover, if its got oil on it the problem is almost certainly cam cover gaskit leaking behind cam baring 1 by pot 1. It runs down to the exact spot your talikng about, probably got a trickle off the bottom of the alternater?    edit, alternator bracket.

My dad was a motor mechanic before the war  and taught me the bits I needed to know on my first car which was a 948cc Triumph Herald.  Swing the bonnet forward and sit on the front wheel whilst doing the tappets!  Them wos the days!! and beer was 1 shilling and 4 pence a pint.  Oh Happy Bloody Days.  We all used to carry a pair of ladies tights in the glove locker in case the fan belt went. That was our story anyway, and I am sticking to it!!!

Now the engine bay is full of pipe work and far too many electronic processors for comfort. Watching Kevin Wood play the Tech2 was a revelation, but one had the sneaking thought in the back of ones mind " how many garages actually have one at £2k a pop"

Anyway looks like one problem sorted either switch weeping a bit or camcover leak manifesting itself at that point and worst case scenario £130 ish for breathers and camcover gaskets done properly and by someone else.
Whats next on the list?

[feeutfo]

only 1 i know of thats not a dealer. Plus the guys on here of course. I'd stick with Kevin personally. Most independents have to spread thier experience over far too many makes and models to be of use with Omega quirks.

Well, the list got a lot shorter when I went to pick up the car from the garage. I pointed out that a 9 year old car was not exactly brand new, and the Penfolds wish list was really designed to return the car to "as new" condition.

When I bought the car from Simon, I got the old servicing bills and it was interesting to match up the stored codes in Tech2 to items in the invoices.

The "probably needs a cam belt change" seemed to fade away when I said I had the main dealer invoice for one last year and 10k miles ago.  Think I might pass on the £600 cam belt change quote.

I had a new Parrot hands free kit fitted to keep me the right side of the law, so now I am good to go.

The autobox gear changes are a lot smoother since Kevin upgraded the software last week, so, touch wood, all is well with the world.

AFAIK the oil pressure switch has a fine tapered thread and it screws into the aluminium oil pump casting on the front of the engine.

Overtightening the oil pressure switch can split the casting or strip the thread and changing the oil pump requires removing the front pulley (which is held on be a super tight bolt, 250 lbft ))

Almost all oil leaks on the Omega are related to weeping cam cover gaskets caused by blocked breathers.

I wonder how many oil pressure switch threads have been stripped/split in an attempt to stop a leak caused by blocked breathers :-/

You and me both I have a slight oil leak under oil pressure switch and have used various washers to cure this to no avail incidently the switch is 4.50 on tc and takes about 2 min to change im still having trouble with this leak and yes i have had to have the pump helicolied as the threads stripped i have also had crank seal done by darth when he did my cambelt and a good job he did too so thats discounted and my local as changed cam cover gaskets it can only be cam shaft seal now im sure
hope you have better luck than me and would be obliged if you due cure it to post up the cure
