Seeing all you mechanical geniuses are practically throwing cars together in a fortnight on here, I thought I'd try to tap some of that knowledge to help me in my humble potterings. I'm currently building (in the weakest possible terms, I'm not touching the internals) an engine for my MX5 and currently have all the ancillaries stripped off so just have a head and block which is about to get a new head gasket, head studs and seals before everything gets bolted back up.

Now the question is, should I, or should I not paint it when it's in this state. Are there any reasons not to do this as I've not noticed many people doing it? My main concern would be that a dark colour would make it harder to spot oil leaks. That and if it starts to flake off it'll look awful.

when I have built cars to be used hard and have had the engine out I have always painted them.

The main reason I do it, is because it makes it much easier for spotting oil leaks (unless it is black).

Process I have used:

Degrease (gunk, diesel etc) soak
A good scrub with a hard brush
Rinse and scrub again
Rinse
Let dry
Plaster it in smooth hammerite using a brush.

However, I never pain any alloy and this is easy to spot oil on anyway and looks nicer if clean than paint imo

Thanks for that Chris. Sounds like we're thinking along the same lines.

Out of interest, does the Hammerite tend to survive the heat and solvent filled environment, or is it worth getting hold of a specialist engine enamel/paint?

Ive done a few now, ;)

Strip the engine
Disk brush and drill brushes
clean, degrease and dry in workshop
mask of all contact areas
Paint

I use P300 proper engine enamel. I get it from Frost.co.uk,. order it and it will be with you in a day or so,

Warning Frost will send you a cracking catelogue and you will end up buying loads of stuff from them.

MX5 engines look 'teh funkeh' when all suited and booted. :)

I have never had a problem with the hammerite coming off, and I give them plenty of stick :)

Al, you need help mate. All those engine shots - I bet they're pinned up on your bedroom wall, eh? :loser: ;)

Thanks everyone.

Although I'm going for a yellow cam cover, if my engine bay ends up looking anything like the first picture Al posted I will by seriously worried about my mental health. :)

Psycholgically, a clean and painted engine bay will make you go faster :ph43r:

Exactly, glitter bollox is a waste of money if you're after performance :D

Function over form every time.

I actually have a yellow cam cover sat in my garage for a 1.6 if you want?

Thanks for the kind offer Al, but it's going on a '99 1.8 head and I have another couple of bits I want doing too so will probably get them all powder coated at the same time.
