Title: GASP!!!!
Post by: STMO123 on 21 August 2006, 21:31:59
The wifes MGZT is due cambelts soon, I thought I'd better prepare myself as I'd heard it was a teensy bit expensive.

JCT600--Full service inc. cambelts front and back--£824+VAT=£968....GASP!!

It's a swine to find anyome around here who'll do it. Apparently, not many have the T4(MG equivalent to Tech 2)

 :o :o :o :o

Damn thats expensive!!! - How much is the cambelt kit on its own?

For the size of car and engines, Omega's are very cheap to maintain yourself.

Even a dealer cambelt change and service from a Vx garage would be about half that price!

God knows....ask Rover....ow no, they dont exist any more......refer to the above for one of the many reasons why!

I know on my BMW V8 the chain driven from the crank only drives one camshaft per bank, and the other camshaft is driven by a secondary chain from the first. Makes sense because chains aren't as easily routed as belts, and when you use duplex chains that generally outlast the engine it's not an issue! But if they've done something similar with belts, that's just insanity :-[

Personally I think the Omega requirement of belt + tensioner change every 40k is a bit of a joke (and even at that it seems some of them don't last that long  ::) ). Every other belt-driven car I've had was at least 80k intervals and there were seldom reports of them breaking even when neglected. Off-topic but why are the GM belts (or tensioners) so comparatively crap? Couldn't they have improved the design when they realised the parts were utter crap and had no chance of lasting the original 80k interval?

Hi Paul,
it is very difficult to specify maintenance schedule based on milleage. Usually engineers tend to talk about hours and then translate it into milleage. Every new technology car cannot use a belt-drive arrangement for high miles as there are cylinder pressures are higher than they used to be on modern engines and this has an effect on the torsional characteristics and increased fatigue on the belt drive as well as other components. Belt drive is a complicated thing as there are many trade offs to consider such as noise, belt slap, axial loading on bearings, wrap angle, durability etc. You cannot have  everything. My dad has a mitsubishi l200 built in 1978 and it has done 400k km the belt has been changed 2 times and the tensioner only once.

Car Mechanics Magazine ran an article on buying second-hand Rover 75s a while ago, the message was stay away from the V6 if nearing 60k because the cambelt change is a 7 hour job.... in a garage! It's anyone's guess how long it would take as a first-time DIY job...

Apparently the V6 is very tight squeeze in the 75 (sideways Vectra-style - it's FWD) and lots of dismanteling is needed before you actually get to the belt. They also mention that the timing kit is essential, but this is a more common issue.

MG's(much like omegas) are worth virtually nothing anyway. Might just have a competition wiyh the wife. No more cambelt changes and we'll see whose goes bang first. (Even though I had mine done 3k ago) ;)
