Has anyone got one of the T connector thingies that go on the rocker cover beather pipe to connect the carb and airbox hoses. Volvo don't make them any more and the bit is completely missing from my car, so it's hard to find something from another car that would work.

It's a 1986 1.4 Auto (B14E engine I think?)

'T' piece - B14 breather Renault part no. R77 05 030 062 currently available "next day" @ £4.12 (inc. vat)

Your local Renault dealer will be able to get one.

Brilliant thank you! I've just ordered one from Renault and it'll be in tomorrow
