My dipstick is blowing out-Please help !!!

Hello BigJhon. In your post I understand, that you just changed the oil, and if I understand, you, this never hapened before. I would double check the oil you put in your tractor. If it's the wrong oil, [for a car-gas engine] the oil will not seat the rings. Your tractor oil must have a C, in the api. [CC CD CF ect] S, in the api is for gas engines. I don't know about your neck of the woods, but were I'm from the api is a small circle, the size of your thum nail, some were on the lable. In that circle you will see the CC CD CF CE ect. If it has some SF SG SH letters that's all right, But it must have the C letters. CE is minimn for turbo charged engines.

Don't know where you are from (how cold it is) but the only time I had this happen was a Fiat (I learned a lot from that experience) and it was condensation freezing in the crankcase vent. If the crankcase vent is not blocked, I don't think blowby or any other effects could generate enough pressure to blow the dipstick out.

The solution is to find that vent and make sure it isn't kinked, blocked by something, or has a low point. (The solution for my Fiat was to junk it, but that's another story.):laughing:

KennyG, Im on Vancouver Island. If it gets down to 23 Feairinhight, [-17 C] that's extreamly cold, for out here. I spun a con rod bearing, because of water in the crank case. The wet sleaves were leaking, I guess the water frose, and pluged the oil intake. If BigJohn has a vent tube, and it's really cold, the wire mesh could freeze up with ice, and block the vent. What I'm under stand is BigJohn just changed the oil, and any water in the crank case. He didn't have the problem before he changed the oil. Thus his problem is most likely some thing he did while changing the oil. As you said the vent could be pluged, but, then it was pluged before he changed the oil I've seen several 6.2 chevy engines hurt from butting 10-30 oil in them. The blow by is extreme.

There is no such thing as the wrong engine oil causing the rings not to seal, *maybe* on a newly rebuilt engine, but certainly not on a used or new one.

My guess is that the draft tube has become blocked due to a nest of some type, the proof would be - leave the oil fill cap on but loose. If the dipstick stays in and there is not a chimney like amount of vapor comming from the fill cap hole, the engine is fine and the vent (draft) tube is plugged.

Hello ModMech. I worked with a guy that stold I-a-lub 40, from our employer, Lorenx Mineing Corp. His truck lasted about three hours, then died. It had no compression at all. I rebuilt a 6.2 engine for a guy that put SF 10-30 oil in his truck that he had just bought, [used] It lasted about a week. The blow buy was so bad that when you took the oil filler tube cap off, you couldn't see for the white smoke. The rings were shot, and the cylinders, were scored. If you look on your dipstick, it will say [use ** oil only] ** been CC, CD, CE, CF, ect. for diesel, and SF, SG, SH ect for gas engines. Turbo charged engines must use SE, for gas, and CE for diesel.
