Bet its the Alcon clutch. I had a six paddle on my fiesta and it fucked up . Was shagged from the start as it was noisey but i didnt know it was the clutch as i thought its new so couldnt be . It started to get crunchy one day then all of a sudden i was stuck at the lights on the fucking a406 at rush hour

XFactor replaced it though so credit to him cause i dunno whther he has been able to get the money back from Alcon yet.

Cars off the road at the mo with suspected clutch problem again so i will be getting something different next time as i had the flywheel refaced and it was fitted correctly just like the first time and its fucked. I dont no for sure its the clutch yet though cause i cant be fucked to sort it at the mo but im pretty sure its going to be.

Heres a pic of it

Thats your problem i reckon, as Quaife sell Silkolene Syn5, they recommend it, it's not what you should use in your gearbox, trust me, been there done that with that oil in an MT75! Don't get me wrong, it's good oil, just not suited to the MT75 with syncros.

The crunching will be because the oil is too slippery, the syncros can't slow down fast enough, syncros go CRUNCH!

Goto Ford and buy 2 litres of their MT75 oil, job done, if you haven't mullered the syncros already.

I use the same oil in gearboxes and diffs................

Silly question time - clutch cable? Not touching the heatshield or melted through in any way is it? I had similar clutch clearing issues albeit 2wd when the cable was mullered.

Should have hydrailced the clutch when it was out anyway

Yep, except mine crunched from 1-2 + 2-3. If your clutch was dragging, surley it would crunch when you put it into 1st from Neutral.

I had an R+D bigtooth gearkit, after getting the gearbox rebuilt twice by R+D using the oil they recommended (Syn5, and everytime the syncros were changed because they were kaput), i went to another gearbox builder (around the corner from Quaife), his exact words were "don't use that shite in an MT75, use the Ford MT75 oil", which i did, hey presto no more crunching

You haven't got a Hydraulic clutch conversion???

I'm surprised, your attention to detail and prep on the car is normally superb....
