engine de-coking solution - SV650.org

I'm wanting to clean out the intakes on my van which have had 50k of egr cack chucked through them and was wondering if anyone had any suggestions on anything that could assist with stripping the crap off.

Any suggestions?

I have no experience de-coking anything that isn't already in bits.

I've seen services such as TerraClean touted on shows like Wheeler Dealers for this kind of thing, but whether it represents value for money I couldn't say having never used it.

I'm going to take all of the induction system off right back to the engine block so I can get in there with a wire brush and spray whatever all over it to help the crud come away a bit easier. I was thinking brake cleaner might do a good job?

Bicarbonate of soda.

Well, it works for two stroke exhausts anyway.

. . or, if not alloy, ( which they probably are

) caustic soda.

Carb cleaner spray.
Be cautious it don't end up getting sucked in the engine heater plugs out and turn it over by hand first before you get any chance of hydraulicing the piston

That could well be what I was thinking of.

It's been a while since I had a two stroke (ooh er).

I was going to mention this too. It's about £100 or it was when I enquired about it, they said they do cars, bikes, vans whatever.

Is it a diesel? If yes then Terraclean will not clean the intake or EGR, it is connected to the fuel system and as such the cleaner will pass through the pump, lines, injectors and cylinders. The intake of a diesel carries only air - and the cylinder blowby, oil mist etc that enters the intake from the crankcase vents, which is what makes up the majority of the crud you'll find clogging the EGR/intake manifold/intercooler/etc depending on where exactly the vent's plugged into the intake system.

GM diesels do recirculate exhaust gases and deposit soot in the intake, as do BMW.
The difference is when BMWs clog it is often the end f days for the vehicle. For GM engined cars is can be an expensive repair.

If poss clean it with carb cleaner but do let the cleaner to drain off and evaporate.

Keep the intake clean, if you don't you can be looking at repairs to the swirl flaps and if not treated also problems with the DPF.
