Who else washes their engine/s?

Part of my long standing engine maintenance routine is to wash the engine and entire engine room after an oil change. I always clean up any spilled oil first. Then after there is no danger of discharging oil I use a mild cleaner (Rolloff) and spray everything down. Then I rinse everything with water from a hose.
After disposing of the water with my wet vac, I run the engine for a few minutes. Finally I finish up with a can of WD-40 that I spray the engine with before wiping up any excess.
My engines on past boats have looked like new after 10 or 12 years of this treatment.
Of course, I have never had such a large engine room to detail before but it just takes a few hours and it always looks so pretty!

Looks really good, a credit to your maintenance schedule.
I do the same myself, mainly because you never know when yoy have to pop in and reset or change a fliter on passage etc. Not that I'd pop in a a dinner Jacket!
However having a clean full size engine room with standing room makes all the difference!

Anyway on anther note my port engine is out and the afternoons entertainment is painting the bilges under my port engine with bilgecote. ( Changing camshaft and tappets) This will occur in airconditioned comfort of course by opening the forward engine room access doors in my Cheoy Lee and letting the a/c from the owners cabin enter.

cleaning engine

isn't rolloff an acid cleaner? wonder if a auto degreaser cleaner would work along with a weak stream pressure cleaner. just worried about exposed wires.

Looks very nice.

I do something similar.

As you know you just have to be careful of the electrical and electronics on the engine.

I also like to run them after a wash to help evaporate off the water.

Realistically, if you are washing off oil and replacing it with WD40....nice but, think about it. Water getting into cracks and crevices isn't good, and only a guess that WD40 is replacing it.

I have run beautiful yachts and grungy commercial vessels...they both run forever, or not. Cleanliness Has it's place, but an engine room is an engine room, not an operating room.

It's what you do in real maintenance that counts, not necessarily over the top cleanliness. Pride is a wonderful thing and can count fo a lot, but it is not magic.

The bilge is a different topic all together, that being crystal clean is magic.

So far, I have just been spot cleaning my engine as needed and as convenient. I'm a lazy mechanic. Any spots of rust I have cleaned, wire brushed, painted or spray with Corrosion X. I then wipe it down with a shop towel.

My ER and engine are not nearly as pretty as Bruce's, and while I may have an excuse of mine being 7 years old and his being new, and I have only owned mine for a year, I think that Bruce's ER would look cleaner in 15 years than mine even if I had a brand new boat fresh off the factory floor.

No fan here of rinsing engines. Water sneaks into bolt holes and corrodes the threads of both bolt and hole. I can tell the engines that have been rinsed or sunk during teardown. More seized and corroded bolts.

Also, rinsing is a good way to kill a Delco alternator. Repaired scores of those, all had water damage.

If you want a clean engine, just wipe it down. These things are not furniture. More important that the machine is in good condition and less that it is spotless.

I always said I wanted to hose down my engines with degreaser and then rinse off, but I never could justify that amount of water/oil in the bilges. I use a spray degreaser and manually wipe down all surfaces. That works great for me and it keeps the engines nice and clean. If I keep up on the maint and give a little wipe down here and there the engines stay pretty clean.

Yup, full washdown on a regular basis and after every long trip, and quick rinses in between.

Bruce, you're cheating. That is a brand new boat's ER. Come back at us in 15 years when a few knots are under the keel. BTW, what does Cummins have as an on engine fuel filter micron rating?

I believe all the Cummins common rail use a 2 micron on-engine filter.

Here is my last boat engine at about 10 years and 2000 hours time.
You will please note that it looks like new and it has no rust in the exposed threads of unused bolt holes.
It is all in what happens after the rinse!
I spent a lot of years maintaining a lot of engines in my business. If I never have to work in a dirty, rusty engine again I will be very thankful. All of my engines are always clean and rust free in our boats and autos. I never paint engines either.

Now this is just me but when I look to buy a boat and it's 10 or more years old I view a spotless engine and engine room as a "what are they hiding" thing. A little oil spot here and there, a box of new filters, a collection of old and new zincs, a spare fan belt or two make me feel a lot better. But, as I said, that's just me.

Bruce am curious tho with WD-40 does that not rapidly deteriorate paint? I feel like any hydrocarbon left on paint on my engines causes peeling pretty rapidly.

Most of the WD-40 is wiped off immediately. It is really there to promote drying of the little seams and cracks that would otherwise rust.
It does leave the surface just a bit shiny so I am sure there is something left behind.
Not sure why your paint is coming off. I have done this for some 20 years now on lots of engines and I have never experienced paint peeling.

The funny thing is that I really do not look at WD-40 as a lubricant. It is a marginal lube at best. What I use it for is for cleaning and displacing water.
It is a great cleaner...and it cleans without destroying.

I like having a clean engine and engine room, but can't bring myself to turn a hose on it. When I clean, it's more of a sponge bath.
