Vacuum leak help please !

[Hopalong64]

2001 2.2

I have an eml on and think it is related to a vacuum leak on top of the engine.

In photos I am pretty sure I can hear a hiss on the red circled line. Also the longer pipe work matched red is pretty manky.

I would like to replace both and any others that may be likely to fail while I'm at it.

I can't for the life of me get the pipes to unclog despite pushing pulling and twisting so any advice gratefully received!

Also, where can I find part numbers / get the bits needed ?

Thanks in advance

Ideally you need a smoke tester (about 30-40 quid off eBay) to find the vac leak. Unless it's already been done it's worth biting the bullet, getting the inlet manifold off and replacing the whole breather system and changing any vac hoses. If you don't fancy that, you can do all the by removing the alternator and oil filter housing - chances are the oil filter housing gasket will be ready for replacement anyway.

Thanks Andy. Amazing how a little job grows !
