has anybody lowered the sub-frame on a 2.2dti for any reason. I have an oil leak  from rear of sump & I found it hard to fit a gasket. I needed another couple of inches, so I guess I need to remove ( or somehow ) lower the piece that have the wishbones attached to & probably the steering link bar. the Vectra workshop manual is no help. so seeking advice please.

Is it possible to undo engine mounts and then jack engine up and then put a block each side between the top of the mount brackets and the underneath of the rubber mounts and that may give you an extra inch or so..

  tried that but I got the engine up at the front but I could not get it enough at the back. somewhere in the bell-housing area it was hitting the bulkhead

Be careful to mark the subframe/chassis rails very carefully to aid refitting... There's about 3mm give at each bolt, which although doesn't sound like alot, it will cause chaos with the geometry.

Need to do similar to the BMW at some point for the sump gasket on that, should be easier on the Omega as you can leave all the steering gear attached

  now you have got me worried. I did think of that & I also thought of using a can of spray paint to mark its position before undoing then on refitting theoretically when paint marks line up I should be ok. the actual sump gasket has a tab on the n/s rear which protrudes from the side & the rear. the rear protruding bit must fit into a slot on the bell- housing. & because of how it is I'm surmising it has to fit to the engine first & sump up to meet it. I also this time will remove the balance pump ( but I need to find out the correct fitting procedure for that )  so the timing will have to be locked at tdc. some ruddy work for a gasket.

That will be a job you will wish you had never started.

Just need to make it shiny and oil tight ready to chop it in for a 540

It's a job that's only worth considering if you're going to keep it for a long time. I did mine on the two-post lift at work and it was still the worst job I've done. That includes the Capri rolling off the ramps on top of me at the end of a clutch change.

Could preempt a bush change while it's in bits

It's using/losing a bit of oil still, about a half litre every fortnight or so... And all from underneath, so sump area...

  I think I could manage with just lowering that stabilising bar that runs along the back of the engine with the wishbones on an inch or so.

If the 540(and I do see the appeal; by the time I'd found the money, the manual 540 E34 estate had sold) is imminent, top up with cheap oil when necessary, and jetwash the bottom of the engine the week you get rid of it.

Sounds like a plan

540i purchase would be job dependent, not imminent, but fingers crossed, before Easter

Six bolts undone until they almost come out might just do it believe the front two bolts are shorter...
