Smoking #1 cylinder on My Ford 3000 Diesel

That it is. There's always an editorial in the paper about the battle to stop the noise. Both side have a point i think. Always like to stop and watch the touch and goes along the highway. Matt

There's nothing quiet about 100,000HP.
I've been just a bit closer than the highway, like next to the runway! 9 shock rings at night is pretty impressive.

Magna Flux (SP): They sprinkle magic pixie dust on the head an put a monster magnet on it. Cracks show up bigger than Dallas. Cool to watch. They've never even charged me to do it at the machine shop. But I have a friendly face

I think you have a ring issue. I know I had a friend who rebuilt an engine and though it was appropriate to line all the rings gaps up. It smoked like a chimney and used oil almost faster then he could add it.

Hi Dave.
I looked what fluxing was after you asked. Sure finds the cracks. I talked to the machine shop that did my head this morning and they magna fluxed the head so I 'm sure I don't have a crack. As far as the ring, I did rotate the rings correctly I believe. I know I didn't line up the gaps.

I went threw the valve seals today and the put a new Oring seal on the exhaust valve. there was no O ring on it, but it had a seal over the guide. the other two had O ring seals and the umbrella seals as they are in the manual. I don't know how much of a difference it will make, but it can't hurt at this point. I'm waiting for the bore gauge on Saturday. Matt

It sound like you've narrowed the suspect list down to a Square cylinder head.

I wonder if these tractors have calendar sleeves or if they have to be bored out.

Hi Dave. The 3000 did not come with sleeves. Would have been simpler to get it back to factory tolerances. I think they can be sleeved though. What do you guys say if I do split the tractor to bore the holes, would it make sense to bore it for sleeves or just over bore? Just asking. I'm still hoping for bad or wrong sized rings instead of a bad cylinder. We'll see this weekend, thanks. Matt

I rebuilt a Jeep CJ3 flathead about 45 years ago. Thought I'd be clever and used chromed rings. That motor used a quart every hundred miles for 3000 miles then stopped burning and behaved decent. Rings seated finally I guess.
Not saying that's your trouble - yours is worse. We'll be interested in the bore specs.

Ok, Here's the numbers for the #1 cylinder. This was with a dial gauge and I think I'm doing this correctly. The dial length is 4.25 inches. I subtract the reading from the gauge from the total length of the 4.25 inches. Example i had a reading of 14 thousands so 4.25- .014 =4.2360. Anyway, I have a wide range of numbers. 4.2320 to 4.2340. So my inexperience is saying that's not too bad. But my gut is saying other things. I'm thinking I'll pull the other pistons and measure those as those weren't smoking so the rings were seated and it would be nice to compare the numbers Thanks for any opinions you all have on these numbers. Matt

Update:
I pulled the other pistons and took measurements.

 

[mtodd101]

Looking at the #2 and #3 pistons, they are blackened on opposite sides. I 'm guessing that is from passing oil before they seated.



One other thing, If the standard bore is 4.2 and I have a reading of .040 over that on #2 and #3 cylinders, how can they be not passing oil and the #1 cylinder is passing oil? Thanks Matt

The taper in #2 &#3 bores scares me even if it doesn't explain why #1 is the oiliest. Could much more blowby from 2 & 3 be what keeps 'em dryer & the 'oily' #1 just be a red herring or receiving the brunt? :confused3:

Hate to think the whole case (eng block) would have to come out to clean up the bores but, at much more that a few thou taper I don't know if I'd even think about the rings for a while. (?)
