I am trying to replace the pipe highlighted on the pic below, (off redtop engine) as it has a hole in it. It is a reducer with an ID of 31mm at the top, 25mm at the bottom, and a length of 65mm.

I can find silicone reducers on the net, but I dont think they are good with oil. Can anyone point me in the right direction please? Or even does someone have one that I could steel / buy?

Cheers

Matt

They're a bugger of a pipe - always had them crease, split or fail in my old Vauxhalls (Mk2 Astra GTE, Calibra 16V etc.).

I never actually found a direct replacement other than main dealer, so replaced with 2nd hand parts. Have you tried the local Vauxhall garage to see what's available?

I bought mine from GM for £8, was about 6 years ago now though

i just used a silicone one. should be find with oil as long as its not in constant contact with oil, as in an oil line.
mine is just a silicone elbow. cheap as chips
