For very thick old oil/goo/crud mixture I find the best method is to paint (or spray) a coat of Diesel on it every day for at least a week - it only takes a minute. This will soften it, then pressure wash (from the hot tap is better) and all the **** should come come off fairly easily.
Blow the oil ways out and dry the bores with a rag after the pressure washer to stop the rust starting off!
looks good! i first used a pressure washer to get the big chunks off the outside, then i used varsol (mineral spirits) and a wire brush to clean the engine block, its a little slow, but it sure gets it clean. are you going to tear it all down? i found mine had a lot of gunky dried out oil in the passages.
i dont know if you have a spare head gasket, but i bought one of these, http://www.ebay.ca/itm/270623312715?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
really inexpensive, but good quality.
good luck!
Nick.
Jep will tear it all down, I think I have to replace some bearings...
Wat did you do to your engine?

Kind regards,
Jonathan
we (my dad and i) started by just pulling every thing out and getting an idea of what's going on with it. we decided to re-true the crank throws and scrape the bearing shells ( could have bought new ones i found out after). we cut the ridges off the top of the cylinder bores and honed them, i bought cords piston rings and fitted them. the head had a crack in it so that had to be welded up and ground, the valves had some issues as well as some of them had melted or something. dad welded them up with stainless rod and ground them to fit on the lathe. i bought a new diaphragm for the fuel pump, new rotor arm and points, and a head gasket. Dad had lots of fun poking around in the oil passages with a wire getting them clean.
we painted all the parts after they were fixed up with a nice green trem-clad
thats about all i can remember for now, here are some pics of some of the various steps. hope it helps some
I will just clean everything, but new bearing shells, and I think I'll go for an Lead free conversion becaus I want to use it often :p
Ow and I'm also thinking about a chemical wash for the enginge to free the oil and water passages.
I'm trying to find the bearing shells for the camshaft and the conrod bearings, can anyone help me?
Maybe there are the same like the Austin Sprite/heleays? or MG?
A company who cleans the tanks of trucks cleaned the engine for me yesterday! Today I've cleaned the last dirt of with a wire brush and painted the crankcase the first layer!
It went from this:
PS: I've found a very good trick to derust parts!
This is wat I do:
You should see small bubbles coming from the metal that is derusting
But never cover the bucket!
Never let the metal parts have contact in the water!
First put everything is place, then switch on the batterycharger!
And Don't put a flame in the water...
...The small bubbles are hydrogen...
... and we all know what happend to the "Hindenburg'' zeplin.

I've had great results using the electrolysis method for rust removal, though it can be a trifle slow on the larger items. Cheap as well, which is always a bonus... Like Nick S, I found it worked a treat softening the old paint too - was dreading a marathon session with the wire brush in the angle grinder, but it literally just wiped off! Is it the electrolysis that softens it, I wonder, or just soaking in the sodium carbonate solution for a while?

Jep, it does indeed soften old paint, it makes live easier!
All the rust, paint en tin oil comes off!
I've cleaned all the engine mountings like that!
I've cleaned some parts and this is how the engine will look wen finished
Just have to fill it again with some inportant parts like camshaft, and crankshaft etc..
