Well, even if I used a solvent, I would still put oil in it and
pressurize the oil system before starting. Bearings and valve
guides will be lubricated with oil, with perhaps a slight trace of
solvent. Then the quick oil change should take care of that.
I agree that kerosene would be a particularly low risk choice.

has some lubricating properties. Anything more volatile than that
and you risk scoring bearings and valve guides on startup.<br><br>

<dd>I have a 4 cylinder MG engine that was removed from a car in good
<br>
<dd>working order. I know the previous owner and I trust

<dd>engine has been stored without valve cover, oil pan, manifolds, etc
<br>
<dd>in a working garage. It basically just sat in the corner for a
year <br>
<dd>or so. I would like to use this engine as is, without
disassembling <br>
<dd>further. My question is, how would you clean this before
use? I <br>
<dd>could use a hose, but I am concerned that water will get trapped in
<br>
<dd>inaccessible places. I also considered spraying it down with
<br>
<dd>WD-40. They make a "big blast" version with a wide
area <br>
<dd>spray. There isn't any major dirt I'm trying to deal with, but
I <br>
<dd>figure a couple of grains of sand could have landed in it <br>
<dd>somewhere. It seems like a rinse would be a good idea.Â
