Cleaning inlet manifolds

[L28 rat]

Hey lads

I scored a set of twin carbs of galderdi (Greg,again thanks bud)

Im in the process of cleaning it all up

Ive scrubbed em down with degreaser and a toothbrush

But the dirty oily marks in the alloy , AARRGH

 

Ive heard molasses is good paint stripper ,cleaner,but on alloy

Mate mentioned bicarb of soda

What do you guys use

 

Also what about polishing them

 

 

[benny]

I blast all my manifolds/alloy bits with bicarb or if its really stuck i use Garnet!! If you have a compressor You can grab a cheap $50 dollar gun from Supercheap otherwise pay someone else to do it!!

mag wheel cleaner works a treat 

[zzzzed]

this stuff works very well.

I used the $50 supercheap gun like benny suggested and the bicarb works a treat on alloy, sand is just to harsh on soft metal.

I thought the wet n dry trick with autosol mite do

But the ruff cast finish is harder to clean than the machined edge of a wheel

[peter mc]

the stuff i have sprays on and you leave it on for 5 minutes and you wash it off with water, its very strong i use it on heads and sumps and front covers and they come out like new ,if its really bad i soda blast it .

Just throw this in here perhaps for future reference

Dont use molasses

There wont be any manifold left

 

 

No i didnt do that,phew

Sweet!

 

I wonder if you push some molasses through the ports if it would be a good way to open them up a bit. (I am thinking more about an EFI manifold)

Greg, there is some goop that is designed to do just that, Jason has done it for his inlet manifold to even up the flow between runners and also open  it up a little.

Thanks for the info. I probably will never get around to it. I have way too many experiments already. Plus I am now going down the ITB path so the injection plenums aren't a priority for me any more....although I guess I'll still have one on my 280zx

It doesnt do nice things to alloy

 

Im doin a wee tank of molasses,ill throw an old crappy manifold in , see what shape it comes out as
