I'm going to remove my injector pump and send it off to have it refurbished. Before I start, to minimise the risk of introducing any contaminants into the pipes leading off to the injectors, I'm wondering about steam cleaning the less than immaculate area of the engine around the pump.

Is that a good idea?

I figure a small handheld steam cleaner will allow me to easily clean the very hard to reach nooks and crannies.

Or should I not bother.

TY
 
I agree I think you will find that a little hh domestic steam cleaner will be useless.
Spray or paint on an emulsifying solvent such as Gunk allow it to soak in then wash off . Pressure wash if possible.

You might find cleaning down with paraffin adequate and simpler. What ever you do you'll end up with a lot of mess in the bilges to mop up.

jizer sprayed on by a domestic house plant sprayer, worked on with paint brush, washed off with a hose, works well

cover switches, sensors etc as a little water helps them fail.

Don't forget to seal up the open ends of pipes and pump couplings once disconnected as there may be flakes of loose paint looking for a new home.
 
Brush cleaner (the blue stuff) works quite well and can be washed off with water. Also aerosol brake parts cleaner is very handy for small areas.
 
I've always used a washing up brush (really cheap) and paraffin to clean engines. Once the job is finished, slop some patio cleaner into the bilges and drain the water tank into it. Let it slop around a while and pump out. Then treat the water tank with Miltons. Turns the job to advantage - clean bilges and tank too.

You are likely to get grief for pumping out that kind of mess.
Personally, I've managed to keep my yacht engines pretty clean in the first place.
You don't want the small of leaking oil and diesel 4ft from your pillow IMHO.
For cleaning around the nooks and crannies before this kind of job, foaming arse, sorry aerosol cleaner is very good.
 
I have some bilge cleaner, I am going to dilute it and stick the detergent intake on my jet washer into it. Spray, wait, spray, wait. Seemed to work on the mucky engine bay sides. I then might use a sparing amount of gunk for the bits of engine I am going to touch up with paint.
 
If you dont take the gear off , not at all difficult at all, otherwise , an old injection pipe on the pump outlet for 1 to determine the start of injection. I have the Sabre instructions on the boat I think, if nobody comes up with some on the net.
