@marks152 Thanks I tried it this morning when the engine was hot and like you I think there is an air leak but it wasn’t possible for me to narrow down its location. That being said, when I moved the pipe highlighted in red it seemed to cause it to rev a little bit so I’m wondering if this may be connected:It doesnt matter. Probably better doing it when its hot do any water will evaporate. Ive seen a 1.2 with a hole in the bottom of the plastic intake manifold.
@marks152 Thanks and no worries mate I know the feeling!That pipes the brake servo pipe. Ive not had chance to look at the data yet. Been mad bust with work.
@marks152 Thanks so if I disconnect the pipe by unclipping from the right hand side where the yellow clip is and put my thumb over the hole it was plugged into and the hissing stops then it would point to either the pipe or servo itself is that right?Disconnect it from the manifold and block the hole in the manifold up. Remember the brakes will be poor so be careful.
@marks152 Thanks again I’ll give it a go this morning and I also noticed earlier that when I had stopped if I press my brake when it’s idling a second or 2 after taking my foot off it caused the revs to increase to over 1k so I’m starting to think it may be the servo itself but I’ll check the pipe more thoroughly as well once it’s disconnected and report back.Yes.
