Omega General Help / Re: Misfire under load 2.5 petrol manual estate

« on: 07 December 2014, 21:45:17 »

I have reassembled, with crank sensor screw tight. I shall find out next Friday if fault is cured or not. Will report back.
Thanks. My feeling was if I change the crank sensor for good spare and fault has gone, it could have been either sensor or loose screw. Either way I would have discarded original sensor, which might be OK.

I've had two auxiliary belt tensioner pulley bearings go, causing the belt to shred or break. I imagine the cam belt pulley bearings are similar, which is why we change them.

Sensor locating screw was loose. Am having difficullty disconnecting the connector, may have to remove either plenum or scuttle. I wouldn't like to do it at the roadside.

Could the loose screw cause my problem?

What you want is someone nearby with a healthy 3.0 V6 Omega, so that you can swap MAF sensors - they are esy to fit.

Thanks to all for advice. Three clawed tool arived today, but it did not shift the filter. So I resorted to the screwdriver. I had to put it through three times, turning it 20 degrees each time, before it would turn by hand. It is now tightened hand tight so next time it should be easy. Thanks. Al.

Thanks! That's easy to change. I assume it will be a Siemens, in which case I have a spare. I will change that first.

Omega General Help / Misfire under load 2.5 petrol manual estate

My favourite Omega, the 2.5 petrol CDX, X reg, mileage 153162, bought from OOF member ajsphead in March 2014, has developed a misfire under extreme load, i.e. full throttle 20mph in 4th gear. No EML on.

Service records show plug change Feb 2013 140000 miles.crank sensor at 144K. e-bay advert stated 'the breathers and plenum have been cleaned at 140K and all the belts etc. done at 133K. the cam cover gaskets are fine too. I've never had a problem with the coil packs'.

Last week I posted my suspicion of leaking scuttle. I have since sealed it, anyway it was dry last night.

Oil/water in plug holes? Plug leads? Coil pack? My money is on coil pack, but I would welcome expert advice.

I have returned car to sister until the tool arrives. I failed today to shift the filter with a tool with a loop of strong fabric.
I was tempted to attack the filter by attempting to shift it with a chisel on the engine end of the filter. seemed worth a try. Is this a good idea?

With a fine tooth ratchet/spanner these will undo most things.

Thanks Tidia. I shall seek one of those locally, or by post. I will report the  result.

Since I bought a chain wrench, I've not needed to use a screwdriver through a filter.

I have removed filters with a bit of sandpaper and an old leather belt, when that was all I could find.

Thanks Nick. I've got a chain wrench, I've got a fabric loop attached to a half inch socket shaft I can wind up till it's tight, and I have got a filter holder ring that's supposed to grip the end of a filter, which it does, but not strongly enough. There is not enough room to swing the chain wrench until it grips. The leather belt sounds quite like the wind-up fabric loop, again it's hard to swing. I shall sleep on it. If you have any more ideas, please advise me.

Used a gloved hand, but watch yourself on the Cat

Tap a long screwdriver in to it  from the two o'clock position and drive it home, the simply pull the screwdriver up and over anticlockwise...

Then unscrew by hand

Thanks Al. I have not done this trick for years. Last time I hit two nails into the base, but on this car I have no access to do that. I fear damaging the filter base or thread. Access is bad. Would putting a long drill through be more prudent?

don't think so...

Looking down the front of the engine the filter sticks straight out at 90°
 Draw a line straight along the body of the filter at tdc. Then an inch towards the blockfrom the head, and about 30° clockwise draw a cross. This is your target. Whack the screwdriver in here and keep going until it stops against the opposite side.
Rotate the filter anticlockwise with the screw driver.

When you fit the new filter, tighten by hand and iut should still undo by hand in 10k miles time

I'm working from below of course. So I draw a vertical line, then go 30 degrees clockwise, or as far as space allows and hammer through a long screwdriver. I push it through until it hits the other side, then do I hammer it through the other side? The heave anticlockwise and pray it budges.

This car is harder to work on than an Omega.

Blooming garages! It was difficult undoing the drain plug. I expect the wheel nuts are jolly tight and the wheels rusted on. Haynes instructs 'only screw the filter on hand tight' but garage mechanics ignore that.
