I need my tractor to blow snow. This is admittedly the minimalist approach. I have zero experience, figuring stuff out as I go, kind of winging it I guess. I figured this might get someone out of a jam, so I posted. Unfortunately, I've got some bigger issues brought on by the overheating. I am getting smoke coming out the breather and am leaking a lot of oil. It always dripped a bit, but its leaking profusely now. Overheating may have damaged a gasket further. Not sure what to do now... I bought a repair manual and i'm contemplating whether or not I can tackle a rebuild on my own... The winter's almost over and I could basically spend my summer on it. If certainly need to draw on the experience of guys like you in the forum to have a chance. I wish I could just download your knowledge :). Jamie [Reply]   [No Email]

Hmmm a pity that you have more problems to contend with. Dieseltech has covered most of the potential damage that could have occurred. Have you removed the engine oil dipstick when the engine is running? A small air/oil spray is not uncommon but if there is a specific blow of air and oil drops coming out that would confirm that compression is passing the piston rings. Has the thermostat change cured the overheating problem? I assume that North American 165 radiator necks are the same as ours in the UK. It is not easy to look down them to see the end of the tubes and if there might be any blockage. This of course only allows a very small area to be seen. Have you used any radiator flushing product? Is there free passage of air through the rad fins. Is your water pump and fan belt OK?. The '203 engine is almost bombproof but like everything else has a limit. Cheers DavidP [Reply]  [No Email]

Sleeves will show damage too. Overheated my S90 puller on the dyno once, melted 2 pistons, stuck the rings and scored sleeves. After it cooled it started back up,lots of blow by though.
