I have been pleasantly surprised by these budget tyres (£50 per corner for 235/45/17)

They do seem to have a quite grippy compound so I don't expect them to last for ever but at that price I don't really care

I bought one of these sets to allow me to cut largish holes.

As mentioned above a holesaw needs a good pilot hole otherwise it will snatch when it breaks through. If I was cutting a hole in flat sheet I would clamp it to a block of wood to give the pilot drill something to bite into. Not sure if that would work with a curved/painted body panel though :-/

The Superb's are superb, but I think to change the cambelt the whole front end has to come off on a V6 

I don't know how much DNA the Volkswagen Audi Group cars share but....

on SWMBOs Golf the front end isn't the nightmare to remove that I anticipated. It's a little like having to remove the inlet plenum or skuttle on an Omega V6. Once you get used to the idea  that it is necessary (and learn the easiest way to remove it) it's not so bad.

General Car Chat / Re: ABS a hindrance?

« on: 27 December 2010, 20:31:27 »

I've never understood how stopping the brake pads from touching the brake disc improves braking?

I'd rather stamp on the brakes and know that I was getting 100% of the available braking force.

A.B.S. is for people who can't drive properly!

Anyone who is of the opinion that "stamping on the brakes" will give "100% of the available braking force" needs to do a session on a skid pan.

I think I read somewhere that all the GM family II engines have the same bolt patterns  :-/

The diameter of the input shaft bush will probably change as the gearbox gets heavier and the clutch splines and release mechanisms are probably different too. Good luck

General Car Chat / Re: HowTo: Fitting Insignia Washer Jets.

« on: 11 September 2010, 15:58:41 »

Bought myself a pair of these last week.

SWMBO's Golf has fan washer jets and they do manage to wet the screen every time.

I will try and take 'before' and 'after' photos from the drivers seat (in my Omega) to show why it is worth doing.

Has it got his & hers temperature controls like the Omega?

If it has are they both set to the same temperature?

If yes and yes then has the linkage fallen off one of the temperature control flaps?

General Car Chat / Re: Bother - advice needed on VW Golf Autobox

« on: 06 June 2010, 11:32:23 »

Generally ATF should come out a darkish red. If its brown, its probably knackered.  Its not easy to see the true colour from a pic.

Probably worth changing the ATF completely anyway....

It was as black as old engine oil

Spent most of yesterday night and this morning searching the internet for information. Haven't found anything approaching the quality of the information on OOF :-/

I think I will get a sump gasket and filter and give it an oil change. 

What I find in the sump will tell me how quickly I need to source a replacement box :-/

« on: 06 June 2010, 10:44:18 »

My key question for any auto gearbox experts out there is:

does the colour of that ATF look terminal? or is it fairly normal for a 100,000 mile vehicle?

General Car Chat / Bother - advice needed on VW Golf Autobox

« on: 05 June 2010, 20:38:21 »

SWMBO's Golf has been slow to engage a gear when first put into R or D so I thought it was time check the autobox oil level.

It took about half a pint of fluid to get it up to the correct level. I put a little too much in to be sure and caught the excess in a bowl.

I'm guessing by the colour of the fluid that this gearbox is not long for this world

The ELM based readers won't give you any more than codes on the Omega.

Did a little test on last tank of LPG, set cruise bang on 65mph instead of the usual 80, over the course of 300 miles? Got almost exactly same mpg as i usually do, and pence per mile was 10.5 instead of 10.6.

Glad there is no saving as i was bored doing 65, and it was taking ages to get places 

Back to usual cruise speeds  8-)

Tunnie , honestly I dont think this calculation reflects correct values.. 

the force you must spend increases  proportional with your speed squared in a fluid , called drag..

check drag at high velocity..

http://en.wikipedia.org/wiki/Drag_(physics)


 I guess some extra factors that Kevin mentioned mislead you..

Drag is the major factor when cruising at motorway speed but I think the Omega is geared to hold the engine at the most efficient RPM when doing 80+ mph.

I do seem to get better MPG if I let the speed drift up in to that range....

Harder than new = could be better, not neccessarily failed 

That's some flawed thinking that is mate
A new seal is soft because soft seals will seal oil better than one that is hard. Once they have started to perish they lose their effectiveness to seal oil. Once they have started to lose the effectiveness to seal oil they have failed.

I am inclined to agree with Andy B if you are talking about a modern(ish) multivalve engine with tight tolerances and bucket cam followers that prevent sideways loading of the valve stems. A failed stem seal is one that has split or fallen off.

If you are refering to the 50 year old Viva engine that went into the Chevette (or any pushrod engine) then the valve stems get moved sideways by the rocking motion of the valve rockers so the seals do need to be flexible. Changing 8 stem seals isn't too painful (especially if you can do it without taking the head off). Changing 24 seals is a whole lot more work (and expense )
