*very big problem! - sister driving my camper to rockingham from sheffield, rings me up to say im in 1st gear wont go any faster!!

when i got it back i took the head off it had melted the pistons to the side of the block

........ engine no.3 went in!!!

Was this a late one Luke, they don't like the heat. I had a hose go on an early DI on the way back from Paris (nearly to the point of siezure), got it fixed, pootled around a bit then had to have the head gasket done, engine is now in van no 3! Yet we are on newgen no 2, having the same thing happen on the way back from Oxford, put holes in 2 pistons!!!
As an emegency measure, you can get some hose repair tape from the motor factor's, or even plumber's mearchants. It's not sticky tape, it's for hoses and only sticks to itself and comes on a roll with a backing you remove before use. Also good for holding mirrors in the Mk2 heads!
