Morning, been looking at doing the mrs 1.7 Puma cambelt as it's just turned 80 (000)

Went pricy first with a quote from local Ford garage, lol £590 inc water pump but they reckon crank pully may not come off & last two they did needed air-chiselling off & then replacing! Extra £200 they reckon if it's stuck = £790

To start with, not that I've worked on these but does the crank pulley even need to come off? On most other engines I thought you just undid the tensioner...been looking at forums on here today though & it looks like it's never easy, not a job for me

Would I be better off just carying on with it til 100-110K miles & then fit a silvertop? 1.6 or 1.8 Zetec E I guess it'll be bit lower at the front but otherwise will it go (more or less) straight in? Anyone else done this?

Other than that it's a nice car, no welding to do so far, touch wood

Cheers
