[xk] XK high colonic

All:
For those fearing the worse, I haven’t done the classic tear down of the
newly acquired XK150 FHC auto, but have decided to bring it back to life and
leave it as is for now. The most difficult part of dealing with cars in the
‘survivor class’ is resisting the temptation to start tarting up one bit,
only to make it look out of place against the other things still in original
kip. This is why I have so many car disassembled…the ‘need’ to pull and
‘restore’ the piece next the piece that I just pulled and ‘restored’.
Logically it can’t end until it is all apart.
Attached is a picture of a flushing rig I made to clear the cooling
system of the inevitable build up of deposits resulting from long term
storage. This ‘still’, circulates a commercial cleaning and descaling
solution at 200 deg F. is a reverse direction. I flushed it over two days
and feel pretty good about the flush, though a bore scope would be needed to
verify. One good aspect is that it allow the engine to be brought up to
operating temp over a long period of time to aid it lube system flushing, as
well. By pre-heating the solution prior to pumping, it is possible to detect
‘cold spots’ on the head indicating blocked passages.
After the usual precautions and preparations, it fired immediately and
sounded great with 50-60 psi oil at idle. The transmission was checked to
the extend that, while on blocks, the wheels rotated counter clockwise in
‘D’ and clockwise in ‘R’…always a good sign.(:slight_smile:
Now onto the brakes in preparation for a test drive.
Has anyone done a re-seal on a water pump? I was not surprised to see it
weeping during the flush after setting for 15 years. Though it might re-seat
during running, I would rather not pull the radiator again if I can replace
or re-seal it now. This is the first 150 I have had the had the original rad
shrouds in place…fibreglass! whodathunkit?

Bruce,
Glad to hear you’re leaving er’ intact, and so happy to see you
found a use for the turkey fryer. :wink: :wink: What did you use as a
flushing solution and what did you use to pump and circulate the
solution. Did you find a lot of crud?
Have fun,

When I pulled the housing, the water rail was packed with the granular
white/grey crap so often seen. I circulated a cold mix of water and a
commercially available cooling system flush for about a day. When I opened
the thermo housing again, the loose material was gone, but the stuffed
packed into the passages was still there,but had softened considerably. I
then did the hot flush and it seemed to remove the now softened crud. I
would have been please to find a bunch of solid crap in the bucket, but did
not. I am assuming (hoping?) that it went into solution. I will be popping a
few freeze plugs and having a look soon.
I am sensitive to this issue as I once creamed a nice 120FHC with
original engine taken from long storage when I started it without flushing
the system. Ran great for 15 minutes, then did an Old Faithful Geyser trick
from the exhaust. Found a hole burned through the head @ #3. When taken
apart, I found jellied crud throughout the cooling system. The only ‘safe’
is to take it down and inspect it.
