| Subject: | Long term engine storage feedback |
Andy,
We have had a lot of engines come through our shop that have been in
longterm storage and here is what I have seen:
1. Richard is correct. The cylinder walls are going to be the problem
area. If you rotate the prop shaft and look inside of the cylinder, you may
see a patch of rust in the barrel. Sometimes, it is surface rust but we
have pulled suspect cylinders and found the corrosion to be deeper than what
could be removed with a hone. This has been more the case with factory
overhauled engines than new manufacture. (Caution: If you rotate the prop
shaft, you will disrupt the preservation process in the carb, air
compressor, mags and cylinders.)
2. I advise my customers to replace the prop shaft seal on new, old stock
engines that have been sitting for 7-8+ years. This is recommended for
convenience. The last thing a new engine owner wants is a leaking prop
shaft seal, so I automatically change this on the engines we sell. (The
Russian rubber does not hold up well.) It is also inexpensive.
3. When we have the nosecase off, it is not uncommon to see some light
corrosion on the cast magnesium case parts.
Closely follow the depreservation process in the maintenance manual when you
are ready to use the engine. Your first oil change should be pretty quick
after the first runs, as the preservative oil thickens with time.
The dessicant in the spark plug holes is very good. Years ago, an outfit in
Kankakee advertised the 14mm plugs but I have never been able to get my
hands on them.
Pappy's oil consumption numbers are consistent with what we are seeing with
our high compression pistons/rings. (We also provide stock compression.)

Jill how should I preserve my engine that will be sitting for a few years. I've
sprayed inside the cylinders with LPS 3 but that's it so far. Sounds like I
should pour oil in them. What else can I do to preserve it?
Thanks
Kendal

Jill,
Skygeek has them in stock.
http://www.skygeek.com/dehydrator-plug-14mm-thread-ms3396-12.html
Also, what is your opinion on fogging oil for preservation in lieu of
pickling oil? Or in combination with pickling oil where the oil doesn't
contact the upper cavities of cylinders or the case?
