Not exactly the same engine, but my 650 compact (Yanmar 2 cyl) had blow by when I got it. I started constant (well, really frequent) oil changes and the problem cleared up. It only takes a couple quarts anyhow.
Are you seeing smoke or just steam? My 332 will mist out a small amount of steam until the engine is completely up to operating temp. At that point it has boiled off the condensation in the crankcase and stops misting steam.
I ran the 332 for close to two hours and it smoked the entire time and left black oil on the side of the engine and front of the mowing deck. It seems to have plenty of power, but I can't handle the smoke. I will change the oil and filter next to see if that helps. Thanks for all the help! I will keep you guys updated on what I find. Don
Well it looks like I have another project. I used seafoam in the fuel, changed the oil and filter. Ran the 332 for a good hour and there was a steady flow of smoke coming out the blowby. Does anyone have a CTM3 Yanmar manual they would be willing to sell for a reasonable price? I am thinking at the least I am looking at a set of rings. Advice on what test to do next? Thanks, Don
Not sure of the hours. The hour meter only showed 437 hours but was not connected!!! The tractor was over heating and I bet the rings are toast! Yes I plan a compression test this fall! Thanks everyone--- Don
Dave can look it up yourself at www.jdparts.com. It is a site supported by JD that you can join with no cost involved. It allows you to look up parts for all JD equipment, see if the part is still available and also the cost at a dealer of your choice. It also lets you know if the dealer has the part in stock or would need to ordered. Hours of reading if you are interested in JDs. Roger
I just did/had done my 345 for a cam change. I bet if you asked the service or parts department at the dealer what gaskets are needed to do what you want you could get a print out of what is needed. After all they are their to assist a customer in the service they are doing. My dealer will at least do that. Roger
Dave I don't use or have a smart phone and only use the desk top computer for these kind of searches. I will be 66 in a couple of days and it is just to hard on my eyes to use little screens for this kind of detail work. Roger
