OK I had a hose burst at the back of the engine, it's the one near the steering column right at the heater matrix. It's fixed, anyway I took the car out 3days later and the clutch is slipping now, was holding perfectly the 3 days before with multiple pulls in the higher gears. First pull since fixing hose and it slipped in 4th as soon as the torque started coming in, at 4200 rpm. Seems a bit of a coincidence that's it slips after having been soaked in glycol. Clutch is an extreme twin plate the same actual clutch andy forest used in his flat 6, its ceramic metallic so I wouldn't think it'll absorb the glycol

Anyway before ripping it out can anyone suggest a cleaning regime, I was thinking have a hose run wateri over it for a couple of hours then let it dry then use carb cleaner. Anyone more up to speed with the characteristics of glycol got a better idea, idea?

 

an unusual failure , from google first option is a load of water wish may wash off the coolant , option 2 if that does not work is brake cleaner, look at it this way you have nothing to loose by trying it 👍

 

Antifreeze is like Brake fluid (both glycol) and wrecks friction plates; it can soak into the friction material and cause it to swell and shed fibres. It definitely does this on brake pads and shoes; makes a right mess of drums. But if you're quick enough to wash it off (water and/or brake cleaner, I wouldn't use carb cleaner) you may get away with it...

Another thought though is that water and degreasing agents could allow corrosion, so it can rust the fingers, fulcrums and may damage the release bearing or the splines. Which may cause a heavy pedal, iffy bite points, slip or judder.

Worst case need a new clutch, so whatever you do now can't make it much worse!
