Hello All,

I am embarking on swapping my inlet manifold for the alloy one, kindly supplied by talkingcars. I've read the relevant guides, clued myself up on the sensor differences (which I shouldn't have as my F is mems 3) the difference in the fuel pipe clip distances and all the other malarkey but as my IMG has been leaking I'd like to give the area where the manifold meets the block a good clean, what would you suggest for this?

I would guess brake fluid would work well enough so long as I'm sparing and give it time to evaporate off before putting the new manifold on? Please do tell me if this would be terribly bad! Or if you have a suggestion that would be better, although I already have some brake fluid so if that'll work I'm unlikely to go shell out for something else as I need to get the gaskets and stainless studs too

Thanks as always,

Ryan

Never heard of brake fluid being used, I'm not sure it evaporates, does it ?

I would use Acetone , ( the wife's nail varnish remover ) if you do not want to buy anything.

Brake fluid does not evaporate would have thought sand paper would be best?

Thanks for the answers!

and well I always assumed it does evaporate as I give all my new brake pads and discs a clean with the fluid to take the protective layer off and it always just seemed to evaporate off, unless I'm confusing it with the brake cleaner I had

Acetone seems like a good shout - I'm just wanting to remove the water staining from head from the IMG leak but with something that isn't going to hang around and get into the combustion chamber

Sandpaper is a good call yes, I'm tempted to see how well I can perhaps tidy up the alloy manifold before fitting with some, but I'm not sure how easy it is/if it's beyond my skills although I've read a guide or two on it

You are probably safer using an alcohol or even petrol rather than Acetone.
Just be careful where you use Acetone if you use it as Acetone & plastics do not mix and will make all your plastics sticky.

Hi Keith, thanks for the advice - one of the threads does mention to use petrol so I may well go down that route but I'll have to buy a jerrycan to put it in first!

You would not need a lot of petrol just suck some out of the tank

Brake fluid has one use, as a hydraulic fluid, it has no other use.
Sand paper is no for me as well, it will damage the face and make it harder for the gasket to seal.

I would use white spirit as a solvent, WD40 is quite good as well.

If you need to get heavy handed a very carefully used blade or decorating scrapper with a broad blade will work.

I was more thinking about the sandpaper to clean the welds in the manifold? But like I say I may leave it as it's a bit beyond my skill level! I doubt I'll need to sand the head to manifold join just clean up the water marks although I guess that'll only become evident once it's taken off

White spirit? Lovely I've got plenty of that around and it'll save me having to siphon from my tank as I don't really like getting petrochemicals in the old mouth, I even use the gloves at petrol stations! Maybe that's a bit OTT but I don't like ingesting fuel too much
