Cleaning intake manifold

[katy81]

Got it off the cat, looks a bit oily.

Should I just take all the sensors off and pressure wash it out?

Or should I petrol clean it with old toothbrush or brake cleaner?


It's a petrol car not diesel so it's not too bad.

Pretty sure it's a big chunk of cast aluminium.

Definitely not plastic

You should most definitely place your intake manifold on the hob, whack the hob on full and go out, or stay in, for an hour.

But why?

I’d be extremely concerned if your intake manifold is connected to the catalyst.
Or has your pet cat got an engine fitted to it, and if so does it purr?

But why?

Because it's off whilst I do the pcv, rocker cover gaskets, spark plugs. So I might as well.

Maybe even dremel some casting marks smooth for that improved air flow.

Anyway hot water didn't work.
I don't have a big enough bucket to fit it in to leave it soaking in petrol.

Break cleaner just made a lot of black crap come out but it doesn't actually look much cleaner.

Thinking of pressure washing it.

I use LIDL kitchen degreaser for this sort of thing.
