gav_113 0 Posted July 3, 2007 Report Share Posted July 3, 2007 hey peeps, right ive had a prob with my car pressurising the header tank for ages now, well since ive had the car!ive never got to the bottom of it, well today i took the thermostat out and had a look.....and found that some one has drilled two holes in it?? well i put a new one in and now it boils up straight away, all the pipes are rock solid.. so i got pissed off and took the head off.i think the head gasket has gone on one cylinder, also i noticed that bits of my old water pump were wedged in the water ways in the gasket!!so i thought well ill just change the gasket and skim the head , until i seen the chain guides. the front one is snapped in two, and the back one is wafer thin!! i can replace the front one, but cant see how to change the back one??what i need to know is....Do i have to remove the gearbox to remove the bottom chain cover???and to top it off i snapped the back engine mount on the way home!!!!all in all not a gd day...

matth76 1 Posted July 3, 2007 Report Share Posted July 3, 2007 No. Although rare, chains can and will snap... meaning end of engine. Just replacing the tensioners is definitely no good. A member on here had their chains snap recently...not good! Gearbox out job unfortunately mate. Link to post Share on other sites
gav_113 0 Posted July 3, 2007 Author Report Share Posted July 3, 2007 what kind of money we talking for chains and guides etc.......?? Link to post Share on other sites
crish72 0 Posted July 4, 2007 Report Share Posted July 4, 2007 Have a search around for "timing chains" - it's been covered thousands of times!But as a guide, mine are getting done right now, all the parts needed cost £198 from VW and my mechanic reckons around £250 labour, probably having a new clutch also whilst the box is off..Chris Link to post Share on other sites
budgie 0 Posted July 5, 2007 Report Share Posted July 5, 2007 dude i just priced up these bits from vw and chains x2 were £80 and tensioners x2 were £55. for genuine parts, you could buy cheaper but gsf said they can only get tensioners and not the chains. Link to post Share on other sites
gav_113 0 Posted July 5, 2007 Author Report Share Posted July 5, 2007 has anyone ever done just the guides and tensioners and not the chains......im skint..or is it not worth the risk....advice pls.. Link to post Share on other sites
matth76 1 Posted July 5, 2007 Report Share Posted July 5, 2007 Not worth the risk mate - Anyway not sure if you can do the bottom tensioner without taking the gearbox out anyway (someone will confirm this) so the chains may as well be done too, and clutch. Mainly for peace of mind but if the chains do need doing in the future you don't want the hassle of having to take the gearbox out all over again. Link to post Share on other sites
philbatesvr6 0 Posted July 6, 2007 Report Share Posted July 6, 2007 yea you have to remove the box to do the lower guide thats why its common practice to replace the clutch as well, i got quoted £400 ish to do the chains guides and clutch from PSI in stoke Link to post Share on other sites
