View Full Version : cambelt again?
This is my first post so apologies if it's in the wrong place but I wasn't sure where to put it!
Having just seen this and I quote "1.8 20v engines are snapping their timing belts at 70,000 - 80,000 miles and the extensive damage this causes is not repairable. The car will need a replacement engine." from http://www.honestjohn.co.uk in the car-by-car breakdown I wonder what the advice is for not only mileage but time (3yrs?) for a cambelt change? Scary as I hear a new engine is around 2,500 sheets
:mad:
This sounds like the Vauxhalls that snapped belts at 65,000 the warrantee ended at 60,000 & the cambelt change was at 80,000
Can't change a cambelt often enough I think now they're pushing it out to the extremes now.
Isn't all cambelt changes for SEAT (and VW / Audi) 60K ?
Wouldn't be wise to run it to 70/80 K if that is the case !
Chain driven V5.....nice :)
Even Better Mark - I agreee with you. Can't change em' enough.
My old Audi used to be 60K and I changed it every 40K along with
the tensioner.
mines on for its 4th change on tuesday,the results scare me, so i do it often,20-30 k's doing tensioners for the first time though as it is whining alot.
why they don't use chains is beyond me,id put up with a bit more engine niose for the peice of mind personally :cheers:

Chains break too Jase.
Quite a few VR6 engines have had this with expensive damage as a result.

VR6 needs changing at 80K, you can normally here than chain rattling before it goes snap..

As Bill has already stated chains can snap too. The single biggest problem with chains though is that they tend to stretch. This limits the service life as a stretched chain tends to do one of two things: snap or get thrown off. Either has the same effect - loss of cam drive while the crank continues to operate the pistons. Not pretty...

alright then ,something that don't bloody stretch,snap,or jump off.
the 21st century and we rely on a plastic belt or a bike chain to keep the most expensive part of our car from going tits up.
get thinking this time next year we could be millionaires:D

I'd rather not thanks - i've spent i've spent more than enough time over the years dicking about with dodgy old Ford OHV motors in my brothers cars. Nasty things. Still could be worse - at least they were OHV and not side valve...

Oh I don't know G...
My old Renault 11 Turbo was pushrod OHV...1397cc. Apart from having to adjust the tappets every now nd then... it put of my ragging and 18psi of boost (amazingly) :p
