DEW 3600 08-21-2012 12:08:08 184.20.58.206 Report to Moderator	I was out leveling my bush hog today and noticed that I am getting a lot of blow bye on my 1977 3600 gaser. Is this something that I should be concerned about? Any help would be greatly appreciated. [Reply]   [No Email]

Did you use a different oil this time when you changed it? Blow by indicates a worn top end but it's not That big of a deal. Oil is cheap. If it annoys you a lot you could do an inframe on it with new rings, rod bearings and a valve job. Probably cost you around $400 or so if you do the work yourself and just bring the head in. Oreilly's Auto will 'rent' you a ring ridge remover for free. Some guys here will pooh pooh an inframe and suggest you go the full monte on a rebuild. Generally though they are talking about diesels where the engine will go 10K hours before it needs opened up and then yes do the whole deal. On a gasser though the top end is only good for 5-6K hours(if that) while the bottom end is good for twice that. $400 would buy you 2-3000 hours which for most of us here is many years worth of mowing and puttering around.

It starts very easy hot or cold I put a new Zenith Carb on it. Seems to have plenty of power I have only used it about 8 hours. I replaced the insterment cluster because the RPM needle was broken but the hour meter was working fine. [Reply]  [No Email]

It will be a while before I can do anything to her. My wife just had surgery on her foot and will be laid up up 6 - 8 weeks so I guess I get to be the house keeper and cook for the next month and a half. Thanks again for all the info.

Go work the snot out of it for half a day or a day. Really work it. Then post back. With 1500 hours it's probably been laying around in a shed it's whole life and never worked. I'll bet it will clear up a lot. I would run a little heavier oil in it. I usually buy a generic diesel rated 15W40 from Fleet Farm and run that in my tractors. [Reply]  [No Email]

I think the she hasn't been well mantained and has set out in the weather paint is really faded I belive the hours to be correct because the old cluster that I took out was made in England. She seems to be a good tractor got her for 3250 with a 6ft Ford 951 Special bush hog. I thought it was a pretty good buy. [Reply]  [No Email]

I'd change to a quality 15W-40 and run the snot out of it before tearing it down. [Reply]  [No Email]
