... ever since my engine bay was awash with oil and I tried to clean it with gunk I have had a few electrical gremlins.

What is the best way to clean the engine bay and get rid of all these?

Can you get the big barrels of brake cleaner to put into a hoselock pressured can and spray it on to clean it all up?

What about getting it steam cleaned?

Duncan, I recommend MucOff bike cleaner for the engine bay.

Slosh a load undiluted into a hand spray container, spray it everywhere you need, leave it to soak in for a few mins then start your engine. Connect a hose onto the hot water tap, then onto the pressure washer and do the business!!

Where the engine bay isn't hot the hot water will evaporate quickly and where it's greasy the hot water will melt away any grease and grime with MuckOff having already been there a few mins to lossen all the crap.

Should come up sparkling!!

For really good degreasing i use an orange degreaser which i buy from my spcialist bike shop. It not not only smells beautifully orange but i have never ever seen a degreaser do such a good job as this. It takes the p1ss out of Gunk which i think stinks to high heaven and isn't that good compared to this stuff. You don;t even have to brush it in. It melts and breaks down grease before your eyes. Fantastic stuff!!

Then wash down with hot water as it is water soluble and bingo!! Super sparkling and grease free. I find some of the bike products i use for my own mountain bikes are much better than some of the automotive products on offer for a lot more money.

Hope this helps :thumb:

Yes Gunk is horrid smelly slimey stuff and i have heard Muc-off is good.
I hope you have good liability insurance for suggesting Duncan does this to his engine/wiring lol.
Sure it will do the job though.

Be careful if you are going to use a pressure washer. Apparently the alternator doesn't like getting wet on a Subaru, and they are big bucks to replace.

Thats why you spray WD40 into the alternator just before you start the pressure washer ( sorry Duncan i forgot to mention that bit :oops: ). I have done it many times on mine and it's never ever caused a problem :P

Ok - one solved. The knock sensor is now working thanks to liberal helpings of brake cleaner

But other issues prevail grrrr

Will have to go through each and every plug in that area...

Cam position sensor, ABS sensor plug, OCV solenoid. What a right royal pain in the arse.

That and it has decided to idle very lean too now up at 17:1 AFR hmmm
