Brutal cleaning method or just right?

Post  rsv1cox on Mon Aug 17, 2015 11:32 pm

A recent ebay purchase described in "My first K&B - Ever" thread arrived "sorta clean" free and with good compression.

Not wanting to disassemble it completely I removed the needle valve, back plate, and glow plug then filled all of the cavities with Simple Green and flipped it over with the prop for a minute or two, dunked it in warm water propping it several more times. Then blew it out with compressed air.

Then filled it up with denatured alcohol, propped it some more, blew it dry and set it in the hot sun to dry. Then saturated it with RemOil spray, propped it some more and blew it out. Reassembled it's smooth as silk but with less compression, seems it loosened the Dykes rings and/or cleaned the varnish off the cylinder wall..

I have used this method many times and it seems to work well with no ill effects if done properly. RemOil is a great cleaner/lubricant but not a good preservative so I usually follow-up with after run oil in the venturi, thrust washer/case interface and exhaust port.

By cleaning this way I maintain the integrity of the gaskets and some degree of originality. Just wondering if you agree?

Not sure Bob, personally I would never immerse an engine in water that I wasn't going to completely dissassemble.

There is a chance that not all of it came out. However, it seems your method is pretty thorough so perhaps all is well.
