I think its called plumbers spray, its a red aerosol that you can spray into a pipe (or inlet) and when it leaks you will see where from since its red - It doesnt stick to the internals either and causes No engine probs

Guy I knew had a Esc Cos and he used it, iv lost his addy now tho I think

Its just like a dye, used it afew time when installing me mums new sink!! its apig to wash off tho bud!

Oh right. Dont need it now anyway - Found the airleak before and my inlets on and running

Thanx anyway

which inlet? u fitted the foci one?

Yes - Check my other thread titled 'FAO Ford Owners'

another way to check for leeks on a inlet manifold is to spray the likes of wd40 etc around the area and listen to the engine note
