Have cleaned down engine case and got rid of all the grease and oil. any suggestions how to detail it further other than painting it so it looks smart.It is a dull grey colour at he moment and want it to be more presentable.

A nifty way to really clean up grotty aluminium is Mr Muscle oven cleaner.

This stuff seems to rip all the baked in grime and is far less streaky in its finish than using mag wheel cleaner.
The cases look like they have just bee sand blasted.

We used to get spectacular results on grubby go-kart engines with it. Vegetable oil would bake into the cases leaving it crappy brown, never to be remove until this stuff was used.

Was concerned about blasting as I thought that the media would get in the oil galleries. have other people blasted cases before? Would Mr muscle work on outside of fuel pump as well?

Probably a custom look but not too wild

Oven cleaner is pretty caustic and can react with aluminium. What type of case are you talking about? Type 1 Magnesium or Type 4 alloy?

Absolutely, it is, that why is cleans up alloy so well. I imagine it removes a couple of microns!!

However, it is not drastic enough to do anything else apart from leaving the alloy looking just about the same as it left the foundry in the first place.
However it will rip the finish off anything polished and leave an "anodised" look so beware on polished ally parts.

The cleaner will work on any surface as far as cleaning off the scunge but the result is the best on alloy.

Try it on a section of the case you cannot see or any other cruddy bit of junk you may have. You may have to experiment with the time you leave it on for and how heavy you apply it.
Make sure you thoroughly degrease and scrub the parts first tho.
As a simple degreaser its not very good and will leave a very blotchy and shitty appearance.

As far as sand cast surfaces go, I think you might like it. looks better than new!

Hi,
This case was bead blasted while apart and came up a treat. I like the look of bare clean metal, but it took a lot of air and washing before I was satisfied that all the grit was gone. If I do another engine I'd probably use the VHT alloy paint for a long lasting good look. I've used VHT paints on other engines (non VW) and it is really good stuff. Works best if baked for a while.
Cheers!
Toby

I don't claim to know by personal experience, but a trusted VW mechanic said that painting your case will keep heat in the motor, thereby increasing your oil temperature.
Best to leave it unpainted according to him. Especially the cylinders and heads, but apparently the case as well.

You bake it in an industrial oven at 200 degrees C for 30 minutes I think. From memory I think it was even recommended on the VHT tin but I may be wrong. Would pay to check this. I had my barrels done this way.
Cheers!

cleaned it all up with mr muscle but i think i will paint it as well for the desired result. need a bit more information on what vassy wrote regarding paint holding the heat in, i think i need to ask around. if it is a problem i will just be happy with the finish i have.

Cheers

M8, forstly, did they come up alright with the oven cleaner?

Secondly, i would not get bent out of shape about painted cases retaining heat.

guya any form of coating effects heat retention..steve knott from comp engines is also a ceramic coater...his view leave the case paint free and i agree...otherwise a factory exchanged engine [aircooled] would of been painted which vw didnot...sounds like there is something there??remember the case also acts as a cooler! cheers dsk steve

I think Brad did proper testing on this and found the paint made stuff all difference.

Now i,m getting confused. The mr muscle did come up alright but not as good as i would like. the picture of the painted case and barrels look trick.I talked to another bloke and he said a light coat of paint SHOULD be fine
