Does anybody know how accurate DIY cylinder-compression gauges are?
Mine was showing around 200 psi on all my Metro cylinders a few weeks (about 500 miles) before the headgasket went.
I've just bought a Micra and it's also showing around 200 psi on all its cylinders as well.
Should I be worried?

Halfords are currently offering a £10 voucher on single transactions over £50 for purchases between 3 and 13 November, redeemable between 14 and 27 November. I reckon that will give me a 13% discount on four canisters of Magnatec 15W-40.

But presumably you have to spend £50 first and the voucher will only be valid for subsequent purchases?

Hello all,
I have a 2ltr petrol transit and have just got a 2.5 ltr diesel engine, gearbox and complete wiring loom but i'm having trouble finding anyone in sheffield thats willing to fit it.
has anyone done this sort of thing before and can give me some advice or know of anyone close to sheffield that could do the job?
Cheers in advance

Summary:
You have:
1. Knackered tranny with petrol engine installed.
2. Diesel engine of doubtful (ebay) provenance.
Previous posters have concluded that the Frankenstine style engine transplant will be difficult if not impossible.
Why not:
1. Sell Diesel engine. You might get more than you paid.
2. Buy new(er) or recon petrol engine - at least it should fit.
Option 3 (as suggested by Hugo) would be to get rid of current van and spare engine and buy a replacement. Wouldn't cost much more than the Frankenstine approach, IMHO
Hi guys
At the Classic Car Show in Birmingham, which was fantastic as usual, I saw a few Interceptors which I adore.
On the windscreen of one was a book open at a page with a picture which showed the last Series 3 (I think) leaving the production line. Two workers were standing beside the car holding a sign which said "Fly high silver bird, may you never want for petrol or oil.......".
It was incredibly poignant and sad. Now, do any of you have this pic or know where I can get it?
Cheers

"a more English spelling"
I had a feeling it was different, but I couldn't remember how!
Can someone recommend a car auction near Sutton for ex-fleet type vehicles? Read more
Blackbushe? Not near you really, but big, and in Surrey.

I recently upgraded from 16" steels to 17" alloys, i could run up to a 100mph ( german autobahn ) with no wobble at all, but the alloys slightly wobble between 65-70 and i've had them balanced twice at two different places. Read more
Have you tried getting the wheel alignment checked? A knock against a kerb around the time you swapped the wheels over could be the problem, with the new alloys providing a red herring.
My wives volvo 480 has an engine cooling fan which continues going well after the engine has stopped: in fact it has recently run the battery flat. Any ideas? Read more
Is it the Turbo model?
I remember back in the late 80s and early 90s things like Saab Turbos and Renault 5 Turbos used to have electric fans that stayed on for ages after the engine turned off. If was still on 20 minutes later I would be concerned.
Folks,
I thought that my Vauxhall Monterey (rebadged Trooper) had surface rust only on its huge chassis members.
Until I took the tank off...

Is this an MOT fail? What are the parameters for holes in box sections? From a mechchanical engineering theory perspective, I understand that box sections can have big holes in them and still have decent stress capabilities.

I'm pretty sure that will fail an MOT - many a Landrover has failed for rot in the rear crossmember. It shouldn'e be too bad to patch - as long as it doesn't extend to the top of the cross member, which will require body removal! I doubt you will be able to do that with a domestic MIG, it won't have enough power. You will be able to do it with a stick welder on a 13amp plug though. It will be a bit awkward with working upside down and with restricted access, so if you're not aufait with the welding, the best bet would be to drop the tank yourself, then get a mobile welder in to slap a patch on it, then underseal yourself and refit the tank. Shouldn't cost too much.

Is it illogical? It must be Citroen....
Folks,
They have just opened in Stockton on Tees, and are doing semi-synth diesel at £5.99 inc VAT.
I don't work for them, but they have a big, nice, shiny depot.

Do owners of cars with AC/CC find them a pain with regards to misting? On colder mornings like today, it mists up easily and I have to put the AC to clear it (And even that takes ages).
I set it to hot often to try and 'dry it out' as it were, but it makes no difference. >:-( Read more
Its almost entirely down to the use of pollen filters. They
severely restrict the amount of fresh air entering the car.
If blocked up, maybe. On my cars I can wind the blower up to full and the draught blows my hair about - no problem there. I change the pollen filter once a year and blow through the condenser outlet at the same time.

Pressure is compression ratio times atmospheric pressure, when done slowly, and ignoring valve leaks. Somewhat higher when done quickly because the gas (air) gets hot when compressed. Atmospheric pressure is about 14.7 lbs per square inch (though the value used for 1 bar is somewhat less at about 14 PSI).
Thus with 9:1 compression ratio (?) you would expect about 9 times 14.7, which is 132 psi, if the gas temperature did not rise (it will), known as iso-thermal. I am a bit rusty these days as to what to add for the temp rise -- known as adiabatic compression. Perhaps 50% is not too much.
