Hi, My name is Jhon & I'm a new member at TBN. I am a 37 yr. old T-4,5 paraplegic wheelchair user & I own a Ford 1100-diesel that my Grandma bought new back in the early '80s. It has been (and still is) a great tractor & has given me NO trouble until a recent issue I had with it. My issue is this & I was hoping that someone might be able to help me with it: Recently, after I changed the oil in the tractor and shut it down to double check the oil level when I pulled the dip stick out, it blew oil in my face (my buddy that was there got a good kick out of that). I didn't think a whole lot about it b/c it seemed to be fine afterwards - pressure seemed alright. The next time that I pulled the tractor out, it only ran for about 3 or 4 min.s & it then blew the dip stick across the yard. I was thinking that maybe there is a PCV valve somewhere that needed to be replaced or maybe some sort of vent tube was blocked. I checked with my local tractor retailer & was told that there is no PCV valve & that maybe it was time for a ring-job?.?. The tractor does not have many hours on it (less than 600) & it has been pretty well maintained do you have any suggestions as to what my problem might be?
My dipstick is blowing out-Please help !!!

your thinking right. first check the pcv valve. and other crankcase openings. check oil pan gasket, valve cover gaskets ect. ring blow by, holes in piston tops. turbo charger gaskets.

check to see if with dipstick out it is getting excessive crankcase pressure then post back.
is it missing or running rough? if no, then I don't suspect stuck valve or holed piston.
if rings were real bad it would be a hard starter.

It could be a PCV valve or other clogged venting apparatus, but a classic diesel issue is crankcase pressure (a lot!) caused by bad rings-- the "blowby" mentioned earlier.
Eliminate the easy stuff first, then try to determine if you're losing compression into the crankcase through worn or broken rings. Has it ever sat idle for an extended time at some point before using it again?

Gotta laugh at all the 'experts' advising to check the PCV. As if it actually has one. Check the crankcase vent tube for blockage or kinks. If that is clear, get ready for piston ring replacement or more significant overhaul.

i'm guessing the 2 guys mentioning pcv aren't old ford guys..

Put streamers on the dipstick. 2 functions. You can find it when it flies across the yard, and kids will think its pretty and chase it.

Crank case vent may be plugged by mud daubers, should point at the ground on one side of the engine. They normally puff a little. Puff a lot and slobber oil out when they get old. No PCV valve on them.

Don't know what the weather is like wherever you are but my BIL's Massey dealer said that his vent tube was plugged with frost, causing a frost plug in his crankcase to blow out of his new-to-him tractor...and blowing oil out the resulting hole

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.
