This isn't model specific the question although I know many here will have done it, like DJ Bucho for instance but PM'ing him would only let me find out the info so I'm posting the question.

I've got the stuff, read the instructions and it's seems pretty straightforward but I was wanting to find out some hints and tips about doing it please.

Anyone?

Hiya mate,

I'd recommend getting an small old paint brush (a 1 inch brush is perfect) so that you can work the Gunk into all the little caps that you can’t quite reach.
Also don’t do it on a warm day (not many of those this time of year I know), otherwise the gunk can dry in places before it has a chance to break down the oil.

I also recommend using it on an engine that has been driven fairly recently, as the heat from the engine softens any old oil on the outside of the engine, (but the heat can also dry out the gunk so its 6 and 2x3 really, but if you put a good bit of gunk on it shouldn’t dry out).

Don’t try and do the whole engine bay at once, Get the hose pipe out and blast the engine to get rid of the min bits of muck and rubbish, and then put the Gunk onto the engine. Work the Gunk in with the brush, the fluid will turn grey in colour as it breaks down the oil, (this is normal). Leave the Gunk on the engine for around 10 minutes (I think the contain says 5 but I always leave it on for a little bit longer), then simply wash off with the hose pipe, and admire the clean engine

Just be careful of any painted area’s, it says on the tin keep away from bodywork, but I’ve used it on my inner wings and its been fine, but it did start to take the high temp paint off my cam cover 

HTH

use CD2 Engine cleaner from halfords instead?

I've used Gunk and it's good stuff. You need patience to do the job properly though.

Click to expand...

Is that the spray stuff?...I found that a bit poor really! Was told Gunk is much better!

i used both, the cleaner from the CD2 stuff is very like gunk - but the clear coat laquer they give u to put on afterwards is good!

Clear coat laquer? That's a new one on me. Presumably it protects the engine from building up more dirt?

yup

My Granny was right, you do learn something every day.

I prefer that Autoglym motorcycle cleaner stuff myself,it does the job but is safe on Paint/rubber/plastic,etc.It doesn't stain either.

ive not used the laquer yet, as im not happy with how clean the bay is and i dont want to seal dirt into it!

No, that wouldn't do.

Gunk and Jizer are all good as long as you follow the instructions, I always spray the engine well with WD40 afterwards, give the same shiny look as laquer, drives a majority of the moisture out of any electrical connectors and lubricates any twiddly bits that stil need to twiddle (technical terminoligy)
