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.)

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?

Or in combination with pickling oil where the oil doesn't contact the upper cavities of cylinders or the case?
