General Car Chat / Re: Pre facelift Omega MV6 back from bodywork

« on: 13 February 2021, 08:59:32 »

Thanks for those suggestions - I’ll investigate the “films”

Not sure how to put up pics on here. Other forums I’m on you can just add images off your photo library but I think I need photobucket for this forum 🤷🏼‍♂️

General Car Chat / Pre facelift Omega MV6 back from bodywork

« on: 12 February 2021, 20:44:29 »

Just got my MK1 Omega MV6 back from paint shop today.

Tidied arches, rear door shut panels and door bottoms.

20 yrs of colour Champagne hard to match but I’m pleased enough.

At 56k miles, leather, CRT700 head set and full paperwork it was worth doing 😊

Does anyone know where you can get the black arch transfers/stickers from?

Evening gents

Just an update.....

I’ve sold the car as a non runner so it’s gone to pastures new.

There’s some work to do on it but the guy is more than up for a challenge.

It’s a bit of closure and sad to see her go , but it’s got a good home.

I’ll concentrate on my other MV6 now and enjoy that 😊

Evening - certainly didn’t force it with the scaffold pole - just used it for leverage on the compression stroke.

Turned it by hand easy enough then hit the compression cycle so it became very stiff - hence the pole. It met solid resistance after a few degrees, so left it at that.

10mm was a perhaps a over-estimate - it is more or less a tooth and a bit.

I’ve got a client who’s a mechanic and agreed he’ll look at (and hopefully fix - subject to bottom end damage) it for me - in lieu of my fee.

Think once heads off all will be revealed.
 
I’ll report back. I can’t pics up easy on this site unfortunately

I’ve seen a couple of rebuilt heads on eBay - cheaper option perhaps, unless piston/bottom end damage. As you say hand it over to knowledgeable mechanic and see if it can be rescued. I’ve had a go and failed (I think) 

There’s only 1 tooth out on belt with what I’m looking at  - not enough to cause damage I wouldn’t have thought. However without the heads off we won’t know. So got to decide what to do, as guess another £600 for MOT work (welding front inner wings, jacking point(s), needs 4 tyres, discs/pads, brake pipes etc.) - probably £1100 to get it roadworthy assuming £300+ to get engine sorted. All engine parts I’ve bought will go again other than 1 head gasket..

I’ve got another MV6 to drive and the poorly one isn’t my daily driver - I can lay it up (again) and mothball it but would like to get it sorted as it’s a nice motor 😊

I was trying to get it to TDC before removing belt but hey ho.

I’ll give some thought what to do with engine now. Can readily remove both heads to see what is issue, but depends if any bent conrods or damaged pistons. Not one to admit defeat and car defo worth saving. Shame is I scrapped a 97k miler about 4 years ago with engine still in 😞

Probably best to rebuild this engine rather than swop engine for something unknown. That’s a job for someone else😄 - I can strip it but  hand it over to someone who knows what they are doing. As I say I had nothing to loose.

Well gentlemen - I think the engine has seized unfortunately.

Tried turning crank clockwise with belt still attached to get to TDC and went fine until it stopped dead. Thinking it was the compression stopping it, I used a length of scaffold pole on end of wrench to get a bit more leverage. Absolutely solid, although I certainly didn’t force it - it should have moved with slight pressure on the pole.  Even if I swung my full 14 stone on it, reckon it wouldn’t shift. I’m assuming the worst to be honest as can’t see what else could be issue. You can rotate back anti-clockwise a little but no clockwise beyond a certain point.

Easier to find a couple of built up s/h heads, but crank/conrods/pistons condition unknown 🤔
Perhaps full engine if I can find one.

I had nothing to loose as labour for stripping engine and replacing head gasket on labour alone would be £400 plus  VAT that I was quoted,  plus parts. Hindsight is  a wonderful thing.

Thanks Nick

The other thing I’ve noticed is watching the cam belt video is that whilst you ensure the idlers are pre-set at 12 & 3 o’clock. I’ve assumed that these are the final positions and turned the eccentric 30mm heads accordingly 🤔 - rather than letting them “move” adjust the timing.

Few school boys errors but it’s all part of learning & understanding 👍

From the pictures I’ve taken and studied, the advanced movement is equivalent to 1 tooth of the belt - so whether it’s jumped or “settled down” on running 🤷🏼‍♂️

Possibly where I have gone wrong in hindsight, is tightening the tensioners hex bolts to a point and then using a 30mm socket to nip up the adjuster in desired position before tightening & torquing  the hex bolt.

I don’t have a 30mm spanner in my collection so improvised. Maybe before I do anything I’ll get one of those today.

Will do - thanks.

wondered if it was pretty close to metal meeting metal.

Just can’t see how it’s happened but I’m a pretty much a novice so must have done something wrong 🤷🏼‍♂️

Got some time this afternoon to screw on the crank timing tool. I’ve rotated it clockwise to the water pump as one does and locked it in place.

Well the timing looks to be well advanced in that all 4 cam sprockets TDC Marks are equally to the right of the backplate cut outs by about 10mm. 

Not sure how mind - but that’s obviously the issue with crap running. I liked to know how it’s happened as I checked and re-checked ??!.

Any pointers to put right greatfully received. Suspect I’ll have to remove belt and start again with the timing as too far to adjust on the belt tensioners.

Ran out of time as had to ferry kids about 

Will be doing this early this week. I was more initially interested in checking the belt, condition and location of sprockets in relation to the backing plate.

See what I come up with

Well mystery continues.🤔

Stripped front of engine and removed cam belt cover.

All present and correct, no issues with belt/rubbing. Turned engine clockwise off crank bolt with socket and all 4 sprockets lined up with cut outs on backing plate. Checked sprockets are correct for each cam which they are.

I ought to take cam covers off next and see what camshafts are doing ?

What I haven’t done yet is dig the crank tool out and see what the does with regards TDC.

Thanks “raywilb” - very kind offer, but we’re nearer south side of York so perhaps a bit too far.

I’ll strip it down this morning and report back.

As for the belt kit it was a Gates set (belt, backing plate, tensioner). I checked & double checked every setting/timing marks and torque before rebuilding and engine was turning over fine on crank with socket bar.

If belt has snapped I should be in line for parts warranty/engine damage claim but as I as I’m not a professional garage,  they’d say I’d fitted it wrong 🤷🏼‍♂️ - if it’s snapped - why??

Well I’ve run car up again and g having changed HT leads, it actually ran ok. It just seemed to need a run up and down and get up to temperature.

However it stalled and now when I try and start it, it just sounds like the starter is spinning - possibly starter motor just spinning the crank ?

Thinking the worst that new belt I’ve put on with tensioner/followers has either come off or jumped. Or something new has failed.

Either way it’s seems I’ve run out of ideas and fizz now 

Options:

To start again,
Have it rebuilt by my local garage (£££)
Replace  engine (anyone got a good s/h engine)?
Sell as is
Break it

It’s done 113k miles and I’m only the second owner and very few PFL MV6s left. It’s fully loaded spec wise so seems a shame to bin it

Oh what to do
