How to dissolve polymerized SVO?

[lifeflower]

Does anyone know what chemical will dissolve polymerized SVO?
I believe my inline Benz 603 IP is gunked up with it after I was unable to purge. 4 out of 6 delivery valves are not squirting. I tried circulating lacquer thinner through the IP, and cranking the engine to get the thinner into the plungers and valves, but they still don't all squirt. I put some polymerized SVO in cups of lacquer thinner, alcohol and carb cleaner. The lacquer thinner seems to dissolve the gelatinous oil somewhat but not completely. The alcohol did nothing and the carb cleaner turned it into a hard black paste that is really nasty.

Benz 603 ... you mean the areo engine as fitted to the Messerschmitt Me 410 and others in the 1940s?

Nothing that I would like to put through an IP.
Can you go into a little more detail?
The way I read it, you have no fuel coming out of some of the injectors.

What about the IP, is that working as expected, or is that the source of the issue?

If it's the IP, then I'm not too sure what i would do.

If it's the injectors, or injector lines, then heat is going to help. Boiling water to start with, poured over them, or dipped in it.

I would have thought it would take an almighty tight blockage to actually block an injector line mind. There is some serious pressure there.

I had exactly the same problem with my Messerschmitt Me 410 and I found the best way was to run it for a few flights on hot Glyc.

Mine's been good as gold ever since.

I've often wondered about storing IPs (as I have a spare for my vehicle in a box).  One I did store with bio in left a residue, perhaps should have been flushed with diesel first.

What a toss pot.

There is actually a chemical used for marine diesels when they're left for a long period. Dissolves all the HFO goop and keeps everything good for when it's started again.

I'll try to find out what it is.

Gun cleaner - cellulose thinners worked for me  to remove polymised oil, horrible stuff.  Be aware that it's not kind to most painted surfaces.

Steve, do you realise this thread is 6 1/2 years old!
