Speed limits are set conservatively enough these days that anyone who doesn't end up feeling comfortable at within 10 MPH of the limit probaby needs to be on a bus, IMHO. If only for the potential to cause a lot more overtakes than is necessary.

Omega General Help / Re: Camshaft replacement

« on: Yesterday at 13:31:23 »

Doctor Gollum,  how can you tell if out 180?

By checking the positions of the cam lobes at the TDC position, as described in my post above.^

I should have said, regarding the Haynes advice regarding cam lobe position, it's best to ignore it.

The TDC markings are the correct reference, and these occur when no.1 cylinder is at TDC at the end of the compression stroke. This means that on No. 1 both cam lobes should be away from the followers (but neither will be straight up!), and, on No. 4, both lobes should be partially acting on the followers (inlet opening and exhaust closing).

Firstly, make sure the crank is turned back to 90 degrees before the TDC timing mark to ensure you don't damage anything while fitting the cams.

You will need to turn them to the TDC mark and then lock them in place. Do you have the locking tool used for cam belt replacement. If not, I would get one before proceeding further.

Often there are flats on the camshafts that you can place a spanner on in order to hold them in place. The valve spring tension will act on the lobes and cause them to try to move, so maybe get an assistant to slip the locking key in while you hold the two cams in place with a pair of spanners?

If you haven't removed the sprockets, it strikes me that you won't be able to correctly reinstall the camshaft seals?

Once you have the cams locked at the TDC position, then carefully turn the crankshaft up from the 90 degree before TDC position until the TDC mark lines up, then proceed to install the cam belt as you would when changing the belt.

Converted mine at about 70K, if memory serves. It's now on 230K and still sweet as a nut. I doubt it's done more than a couple of K on petrol (plus warmup time) in that period. So yes, go for it. Get a decent SGI system (many of us have used the AC Stag systems) and you can't go wrong.

I do hope they remember that a key part of the punish^h^h^h^h^h^h rehabilitation process revolves around Big Winston knowing exactly why he's in the slammer.

Range Rovers certainly feel like you only have to go round a corner at above walking pace to put them on their side. Are we sure there was a second vehicle involved?

General Car Chat / Re: Astra oil pressure warning light coming on

« on: 16 January 2019, 13:22:15 »

A 20% difference in hot viscosity isn't going to be the problem, especially in the middle of winter.

Agreed that a manual pressure gauge you can check it with would be ideal, but, if it's genuinely got no oil pressure, then it's probably already far enough gone that it doesn't matter.

Omega General Help / Re: 3.0V6 not starting on all cylinders, black smoke, strange errorcodes

« on: 16 January 2019, 11:42:45 »

Yep, and the starting enrchment on these engines will foul the plugs in short order if there are any hitches on a cold start, so the plugs need to come out and be dried off anyway. While you're there check they are all sparking.

There was a change in the wiring of the TPS sensor between a couple of variants of the non-DBW V6 which results in it being back to front with some combinations of parts. Might be worth getting some live data out of it to see what the TPS is reporting, as we suspect the loom has been changed.

I'm guessing that TPS is probably the main fuelling input until the engine is established at idle and the MAF has started to work. TPS will also result in "flood clear" mode if it's reporting 100% throttle on a closed throttle, so it will never start unless you've got the accelerator pressed, and then you only get one spot where there's neither massive overfuelling nor not enough!

Lambda sensor errors won't cause a starting problem. They have no input until they have warmed up and begin operating.

The crass ridicule meted out by micron and barnier on sky TV this morning was astounding.
" We know what the UK doesn't want ,but not what it does want..."

Well here's a clue , everything you said Nein or Non to.

Yes they're not looking so smug this morning are they? 

And I bet your mates down the local aint so cock a hoop either! 

I think that those MPs that voted against the deal and who represent constituencies that voted to leave shoud probably start updating their CVs before the next election.

Updating their CVs? I think they might need to be trying to convince the local councils to lower the streetlights to below neck height once the "yellow jacket" brigade get going.

Took a look at TBE's headlight washers - I thought I'd pulled the fuse, but that looks to be there, so lost interest.

I've just had to replace the pump on mine.

General Car Chat / Re: Million uninsured drivers Swintons

« on: 16 January 2019, 09:29:42 »

I went to a lecture by the ANPR manager for a local police force some years back. He said that they had to turn off reporting of untaxed / uninsured cars because the volume of "hits" risked bringing their system down.

They are more interested in solving serious crime and anti-terrorism.

Of course, the roadside ANPRs might pull you over if you're unlucky, but my understanding is that they can't prosecute by post after the fact (unlike for speeding).

General Car Chat / Re: Foot pump

« on: 12 January 2019, 19:41:16 »

The foot pumps available these days all have flimsy frames that bend the first time you step on them, IME. You then take them back and get them changed and next time the flimsy plastic T piece that connects the pressure gauge breaks off.

I have recently bought a reliable one, though. It was an old Dunlop Major from a vintage shop. Rescued it from being turned into a table lamp by some hipster, no doubt.
