General Car Chat / Re: Keeping these Omegas on the road for a little bit longer

« on: 02 September 2020, 14:53:30 »

I'm pleased to say the W reg passed its test today - headlight aim not quite spot (but close) due to my improvised bits of tape on the garage door, but at least the tester managed to adjust it this time.

Just got to buy some road tax and enjoy being behind the wheel of this car again after 4 years of it standing on the driveway. She's a bit tatty around the edges but mechanically sound, so will now be the winter car and can change over to the tidy X reg next spring.

New headlight adjuster fitted at weekend, unit reassembled and fitted back into car. Booked re-test for tomorrow.

I had the dreaded rev counter flicker at zero, with no speedo occur yesterday (fuel & temp gauges ok)  - binacle out and cleaned contacts - all seems okay now.

Fingers crossed, it'll be good to get a few miles under its belt during the coming months

Omega General Help / Re: Engine noise @ 1 second frequency

Think I've answered my own question - new new belt on order

Does the squeak frequency vary with engine speed?

Yes  but becomes less of an issue as the engine noise drowns out the squeak / squeal.

Just been out there and ran the engine for 20 minutes with all lights on to provide the engine with some load. There's no noise at all when it's cold, only squeals when it is nearly up to temp. So in summary it does look like the aux belt is at fault, even at twice a lap. I'll avoid going out there today to change it around (or even put the old belt on), as it's due its re-test tomorrow, and at the moment it isn't exactly broken.

Incidentally, this belt has been mentioned a while back, as I struggled to get a standard size on there (James CDX will back me up here), hence fitting the 2025mm belt, which I'm beginning to think is the problem, especially when it gets warm.

2000 Model Year includes the dbw cars... 2.2/2.6/3.2
Hence the continuous confusion....

A 2001 2.5 is dealer principle registering a dusty hulk in the corner of the showroom just to get rid of it

Can't argue with that, but you'd still be hard pushed to find a 1999 2.6 - earliest reg would be a Y

New cam belt and rollers fitted, as well as replacement tensioner pulley and aux belt. Removed aux belt this afternoon and ran for 15 seconds, no noise. All pulleys feel free with no noticeable slop.

So noise is obviously something to do with aux belt or pulleys, but nothing I can think of has a 1 second frequency. All the pulleys (alternator, tensioner, water pump, PAS pump and air con comp) will be spinning faster than the crank shaft, so they're out of the equation.

Perhaps it is the aux belt, but 2 squeaks per cycle seems strange?

2.5 does indeed have a 160mph speedo.

The 2.5 engined Omegas were still being registered in Jan 2001, so even with an overlap, I doubt you would find a 1999 2.6

Omega General Help / Engine noise @ 1 second frequency

« on: 31 August 2020, 18:14:39 »

Omega 2.5 V6 engine up to temperature and making a squealing noise every second.

New aux belt (2025mm) 18 months ago, but car has been SORNed for last 3 years, started regularly but long periods of inactivity. By my calculations at 500rpm tickover, 160mm diameter crank pulley, the belt should lap at 2 seconds, so now I'm not so sure what the noise could be, unless the belt squeals twice per lap?

Anyone experienced anything similar, or know what frequency any part of the engine could be attributed to 1 second frequency? (timed at 61 times per minute).

General Car Chat / Keeping these Omegas on the road for a little bit longer

It's good to hear about recent MOT test passes, just like Tony's this week. These two have also been for their test this week, the X reg sailing through with just advisories for rear tyres. The W reg has been off the road for the last 3 years, requiring a lot of work to get it into good order. I very nearly dismantled it for spares, after it collided with a small brick wall and ended up on top of it, causing damage to the wishbones and steering, but after finding there wasn't any penetrative corrosion anywhere, reconsidered and decided to tidy it up. I've covered every inch of it with work to the engine, cambelt kit, rust removal and prevention inside sills, wheel arches and chassis rails, replacement handbrake cable, new wishbones and steering, so after around a spend of £1200 I've got something half decent to run through the winter.



It didn't get a ticket due to headlight aim, but sailed through on everything else bar a couple of tyres.



So this will look familiar no doubt - crumbled headlight adjuster.



After all that work I'm pleased as punch to have the car back up to scratch - there'll be a couple more years left in it yet.
