Title: had compression..........now don't
Post by: Brad B on October 12, 2008, 05:02:12 PM

I dug out an old enya engine that I got someplace...  It was full of old dried castor but it had GREAT compression.  I took it apart, cleaned it. probably made a mistake, but I took off the rings and cleaned the piston.  Made certain I put the rings back on in the same grove and the same side up.  I lost about 1/2 the compression that I had.  Will it come back after I run it and the rings seat again?  Or should I just get a new set of rings for it and start over?  Thanks, B

Should be fine... nature of the beast. Put a few drops of castor in it and flip it. Should see improvement.

Hi all.
You have leave it without the castor old varnish coat it had......really is a worn engine, but you can try running it on tne bench with all castor (up to 30%) for some high revs runs to let it restore the compression..... tell what happens please.

Good luck, I´ve seen really only few Enya´s worn out.

Regards from Spain.
