i used hammerite metal paint on my block, recommended by the god of the fiat/lancia twin-cam, guy croft :thumbs:

no issues with flaking or anything, and seems to be quite tough.

as guy himself says, it with-stands the temperature on his race engines so i'm happy it will be fine on my block ;) didn't use it on the heads though, for that i did use the high temperature paint :thumbs:

I used the Halfords hi-temp paint on my engine. The instructions say remove all rust before applying. Well unfortunately I just couldn't - I went around as much as I could with a drill-mounted wire brush, and applied several coats and it baked out nicely with engine heat, but after just over 12 months the rust is coming through again. At least Hammerite can be applied over rust, although I've no idea what heat cycling might do to it.

I think I might try silver smoothrite on the gearbox as well - all the nice silver paint from the rebuild is flaking off... :cry:

i used some good quality high temp paint, i spent hours cleaning the block off with a wire wheel on a drill, iv not even run the engine and its flaking off already :mad: my guess is cleaning the block off to a high finish doesn't give the paint anything to stick to, i should have keyed it before painting... i just thought this paint would stick to anything... thing is i can get to the block easily with the manifold set up on mine, ill just touch it up as i go.

i went for the high temp paint as iv heard hammerite isn't the paint it used to be with restrictions on toxic additives. iv used it on the brake calipers tho and its covered really well and withstood some brake fluid during bleeding :)

I took my heads/camhousings and inlets back to decent finish with wire brush/wet'n'dry and general cleaning.

Cleaned the block with some industrial de-greaser (killed a patch of my lawn - poisoned local water supply - maybe?)
Was left with a coarse oxidised block, so cleaned the metal with brake cleaner prior to painting with Hammerite Black.

I've painted a few engines in the past with hammerite and the paint doesn't tend to flake or bubble.
Hammerite goes down like Tar and as long as you give it a good 48hrs - week to dry and harden (speeds up if you are painting somewhere warm) it will remain with the metal for some time.

See pic attached: Just before i removed the dodgey red paintjob on the cam covers:thumbs:

did anybody spray the camshaft housing or the trumpets may i ask?
Paint results. Unfortunately I did a quick final spray of carb cleaner to clean out the oil passages of the cam supports carefully and a few drops got onto the side of the back paint. Acted like paint stripper:cry::cry::cry:

Touched it back up though. So when I clean my carbs, they will need to be removed!
