from Old English White to green moss and rust

this washing up bowl looks like a prop from the young ones house, but it's just the thing for containing all this guck. this toothbrush has been used to clean the whole project.

gunk stands a better chance of cleaning the parts better if left to soak in for a while.

while that soaks in, the cylinder heads get a coat of it.

brush it into every corner.

no stranger to cleaning are we.

get in there! this area is rather crucial to the happy running of the motor, major clean up before that valve seat is inspected.

Sprocket, just seen this company on FB market,

machine 7.com Classic VW spares.

If it’s of any use.

chers Rob, I'll look them up, always room for another competitive car parts company. With more you scan for special offers the more you can stick to budget.

a bath for the jugs after 24hrs soaking in Gunk, good scrub to get that ground on grease off.

same thing for the cylinder heads, good scrub.

look what turned up, once the dirt and grease was washed out, the reason I couldn't seat the socket to unscrew the plug in cylinder three. A collar of some sort had got itself wedged in there. problem solved.

the heads were given another coat of Gunk, before being subjected to a very helpful jet spray.

the heads were a lot cleaner afterwards

also out were the exhaust and heat exchanger assembly.

the spraying exposed the state of the tinwork, the left one was solid.

the rust holes on the right side heat exchanger is too far gone for use.

the pipework was also sprayed, water shot out from the larger pipe, but the narrower one is absolutely chocker block with carbon, I may have found the main reason why the engine suffered an over heating, causing the blackness we've seen.

not a slight blockage, but a blockage from one end to the other.

the carbon is packed in there.

the curved opening area can be drilled out, but the centre of the pipe has to be accessed by cutting, drilling and clearing out from one end to the other.

the larger pipe isn't blocked, water shot through there coming out the other ends.

the valve tops were sprayed, but they need longer soaking in the gunk to soften the deposits.

Small pipe is a heater for the manifold, prevents it icing up, it works by routing hot exhaust gases under the manifold, using a long piece of wire in a drill breaks up the carbon,
or what I used to do with cement mixer exhausts was heat them up with oxyacetylene burners, this drys out the carbon and it just falls out with a tap
 
the jugs going on the right way around this time, "I wondered who'd be the first to spot that"

holding the rings down with a band of cardboard, tapping the jugs into place with the gaskets on the other side, this time.
