My engine wasn't smoking and the plug was clean as well. My feelings are this one is worn out. 1 Share this post Link to post Share on other sites

Fj40z 231 #30 Posted Monday at 08:51 PM Well she’s gone. I suspected that the general consensus here was correct in that I was needing an overhaul. Had even talked with a guy about bringing it in for motor work next week. Tried to get home and mow again before a storm hit and she let go. Running fine as usual until it wasn’t. Loud rattle followed by the side of the block getting blown out. Really bummed about this. 7 Share this post Link to post Share on other sites
rjg854 13,330 #31 Posted Monday at 09:04 PM That's tough to lose that block, 16's are getting hard to find. Hopefully you will be able to replace it. Share this post Link to post Share on other sites

I obviously hate it just from the point of having to spend money and deal with it but what stings the most is knowing there’s a dang good motor gone from the pool. Of course it has to happen after literally talking to a guy about rebuilding it this past Friday. 1 Share this post Link to post Share on other sites

Fj40z 231 #38 Posted Monday at 10:55 PM She grenaded alright. Storm finally passed so I was able to get back over and check. Big hole blown out right by the starter. Not only is the motor gutted but so am I. 2 Share this post Link to post Share on other sites

I'm still a little curious how it was going through so much oil without smoking. 1 Share this post Link to post Share on other sites
Fj40z 231 #42 Posted yesterday at 01:00 AM @ineedanother it wasn’t losing oil profusely but I would definitely have to add a little before every time I mowed. With that being said I never saw or smelled one puff of burning air. Share this post Link to post Share on other sites

I have an oil pan gasket on the shelf and think I'll order a couple more. It's a bit of work but the last ones I removed weren't that big of a deal and worth it considering the alternative.

I have been keeping my eye out for one of the BS vanguards and have just missed a couple good deals. they seem to be more plentiful than the Big Block Kohlers around here anyhow. Just a thought.... @kpinnc Has done a few Vangaurd swaps if I remember correctly may be able to help u out some.
