a few of you on here are into your fords, does anyone know if the 1.25 is an interference engine? ive not got access to autodata at the mo and someone wants me to change the belt on a 1.25 where the belts slipped (tensioner failed)
 
unlucky. it was started up, sounded rough and driven about 20 miles home! for fun i might get the plugs out and see if you can see gouges on the pistons
 
saying that, cosmetically its not actually in bad nick, i dont think shes trashed it too badly on bollards and such. shame though because she "loved" it. it was dependable but goes to show you how important it is to keep it serviced right.

to be fair though, she has no real interest in cars (how many women do?) so it was hardly something she would have thought much about. no harm in reading the manual though!
 
but she said it sounded terrible. she described it and i got the impression of a dry top end so thought it woudl just need oil.

the belt is barely on. getting the plugs out and looking will be useful. would love an endoscope
 
apparently it ran "normal"

shes due to replace it with a new car anyway so itll prolly end up being scrapped, shed rather not spend money on it when she was planning to replace it so soon anyway

£13k going into a new fester
 
step away from the handbags ladies.

ill try and pop round there on monday, explaining that her car created an internet barney and im gonna try and get a pic of the pistons lol
 
im hedging my bets on "absolutely rogered"

it was just the weight of the belt keeping it on the cam pulleys. on the intake cam (the one nearer the front of the car) the teeth of the belt were resting on the teeth of the pulley. i think when the engine was running there was enough tension to keep it timed. she made one stop on the way home and after that it stalled a couple times in traffic the revs were hunting (classic lambda seeing all sorts of gasses that it shoudlnt)

since then it has been started and stopped a couple times.

wonder if shell wanna sell it for buttons. the mech work i do on the side has been a bit slow lately
 
well, just got back from a noon round there putting a new belt kit on there

cheapest i could find was £45 and it was a GATES! rocked up, stripped it down, got the crank to tdc, belt off and realigned the cams. intake cam had jumped two or three teeth, it was at last 30* out, maybe more.

old tension was proper fubar, might try and get some pics up. put the new belt on, tried to retime it without faffing with the cam pulleys but couldnt get the tension i liked.

did it all properly, put it back together far enough that it could be started. i knew it went round without making contact but who knows the state of the valves

fired it up and could hear all sorts (then remembered one wheel was off, one disc would be spinning) so put my foot on the brakes and all was silent and all was good in the world

friggin thing is good for another 96k.

old tensioner had failed badly, the plastic roller was off the bearing, god knows how it escaped because there didnt look like there was enough space for it to get past the belt and cover.

fixed
 
cam pulleys can unbolt, theyre on a taper and move independantly of the cams so you can get the tension perfect if you try.. so i did

fun fun fun
