I have a 78 140 johnnie (mod. 140tl78c ser. j4990278). At the end last year, I noticed my lower engine crank seals leaking. Winter project, change them out. Going to put in new pump kit and t-stats. Is there anything else I should do at this time. P.S. don't laugh, this engine may be old but it has treated me well. Compression 130 on all cyls. Thanks for any advice.
