Ridding an engine of Mayonnaise

[Wingedcat]

Hi,
I'm doing a head gasket job on a K-series. Now, I've done this before
on my own car, also a K-series, and the cross-contamination was such
that oil leaked into the coolant, with the oil itself being as clean
as a whistle. In this case I simply flushed out the coolant system
until clean (although having said this the contamination was never
that bad).

I have just lifted the dipstick on this other example, and judging by
the huge build-up of sludge, I reckon the whole engine is FULL of oil/
water emulsion. What's the best way of cleaning all this out? My ideas
so far are:

1. Engine flush using proprietary engine-flush (Forte or similar)
2. Taking off the sump and attempting to wipe out (?) the sludge, or
use a degreaser like Gunk or something.
3. Filling the engine with oil then draining, changing, repeat til oil
is clean.

Any help gratefully received.

Thanks

the sludge will largely disappear after the engine has got up to full
temperature for a while. Change the oil now when hot, then give it a good
run, thirty miles or so on a motorway should do, you will probably find most
sludge has gone. then regular changes as needed.

Sump off is dull but probably fastest, you'll still need to do 1 or 3
afterwards, but hopefully only once.

Sorry, radiator off. The oils not normally that bad to get clean, it gets
hot enough to boil most of the emulsion off, I'd imagine engine flush
would make life worse.

Yes but the coolant is not contaminated. The mayo is in the oilways.

How much do you think is in there? Fresh oil at the very least. I would be
cautious of running it alot if there is much water in it, as there have been
issues of seized cams from running the bearings on these from watery oil...

let the oil settle then drain. refill with fresh oil and a filter change.

Engine flush may cause the engine to state using oil.

Remainder of the water should evaporate off.

Only if build-ups of crap are all that's holding the oil in. In which
case, you've got bigger problems than whether you flush or not.
