Hdi engine clean
#1
Anybody recommend a good degreaser/cleaner?
I still cant find where the diesel is leaking from so plan on cleaning the engine down so i can trace its source

Gunk degreaser was recommended to me but a friends dad, its what he uses when restoring his motorbikes. Available from halfords and online. That and a steam clean should clean it up. Never been brave enough to steam clean mine but i would like to.

Same here, but i have no choice as its covered in diesel at the moment and have no other way of finding the leak. I'll try and clean it with as much degreaser as possible then take it to a local jetwash and pressure wash it

Pools of diesel by the injectors? Think they left the factory like that. Tongue

I've just used the Halfords degreaser foam in a green can (cant remember the actual brand), brushes around and jetwashed off, seemed to work well.

How did you guess? Rofl

What are the main things to cover up, battery/ecu/relay box area, anywhere else?

Cover up?? lol I don't cover anything, just run the engine so its warm, do the jetwashing and then drive it after so water doesn't get a chance to soak in anywhere.

Obviously don't blast directly at the ECU and plugs in close proximity, and if you've got a cone filter, don't shoot at that. Also, cleaning the battery is a good idea rather than covering it, crap on it can allow a short between the terminals and drain it slowly, some spray grease on the terminals after is useful though.

Edit - Disclaimer....I've done it hundreds of times without issues, if yours breaks I don't take responsibility. Tongue

Gunk is complete rubbish and for the price well, Best stuff I have found and leaves everything grease free but of course it needs rubbing in

Big fan of Jizer myself, for the name if nothing else. It's nowhere near as cheap as that astonish stuff mind!

I paid around £3 including delivery from ebay, still cheaper than other degreasers out there

Finally got round to cleaning the engine, worked brilliantly and only used less than a 1/3 of the bottle! Not the greatest pics as it was way too sunny and created too many shadows
