Oil from Exhaust Manifold

[Ukjay]

Hi

Whilst tipping some muck yesterday, I noticed some oil seeping from the exhaust manifold nearest the cab on our JD 2140 / 2040 as I was getting back into the cab, so would this indicate the start of worn valve stem oil seals?

Doesn't smoke for something this age, so not burning oil at a rate, just looking so that I can plan in if this is the possible cause - along with manifold gasket, as don't like oil leaks if I can stop them.

Is it from the exhaust manifold or is that just where it's apparent? Usually it's weeping from the rocker cover above and you don't see it until the manifold.

Are you working this tractor, not running doing small jobs but WORKING it?

I used to have 2040 which needed engine oil change every 100 hours but if it went 120 hours then oil would start leaking from rocker cover,, change oil and no more leaks also it did not like toodling about for too long

It looked to be coming from the exhast manifold from what I can see - but I will have a closer look as I was in more of that Welsh Sunshine

Unfortunately it will never really get worked here in terms of ploughing etc. All I use it for is flail mowing, rolling, harrowing, plus spent a few hours knocking in a load of posts with the PN and towing muck trailer to empty it.

If the tractor is idle( not under pressure or not moving and being used) it just needs a good days work to get it out. There is a seal somewhere on the exhaust that will leak if the tractor isnt under much pressure for long.

I never had that issue on my 2140 but the naturally aspirated six cylinder 3050 pished oil out of the exhaust from near new if only doing very light work or idling. This was due to the valve seals leaking down. It did pull like a train and never visibly consumed oil on the dipstick and since it seldom did such light work, it was no bother. I remember that if it was put on the bale wrapper it was guaranteed to leak.

Is it a 2140 or 2040 ? change engine oil first, once oil loses its lubericity the gaskets start to leak.Different issues on turbo and non turbo engines.

If changin oil get some lucas oil stabiliser and put some of it in with the oil. Its thick stuf but helps with oil consumption,leaks and dry starts. Wev used it and its defo a good job

The sump on these HD engines is tiny and hold little oil, which combined with the performance quality of oil at the time of manufacture dictated a very short [100 hours in the case of the 2140] oil change interval with a filter change every other. However, with the advent of long drain oil, which nearly all currently used quality oils are, 200 hours are fine. Indeed my own very hard worked 2140 was run with long drain oil from around 1990 to this day on 200 hour services. It mowed with 8ft Kidd Clippers, carted with eight ton trailers, ran a mixer wagon for years and its engine is still perfect at something over 12,000 hours and the contractor that now owns it has only this year taken it off raking duties, it being replaced by a 150hp tractor.

This is with E5/MB228.3 spec oil or better. It started off when I first started using so-called SHPD [super high performance diesel] oils in 1988. However I found with the Same Titan in 1993 that with constant full power full throttle use on the forage harvester using 228.1 oil, that even with that quality the oil suddenly and permanently lost viscosity, resulting in a dramatic increase in oil consumption at around 150 hours use every time. Using 228.3 allowed some leeway of 20 to 30 hours to finish a contracting job away from home with the oil still good.

Having said that, my little skid steer loaders work quite hard and even with long drain oil the oil loses its shear strength and viscosity soon after 200 hours, again resulting in increased consumption. These are little 2.0 indirect injection engines which seem to be particularly hard on the oil considering no turbo and only 44hp, even though the oil stays relatively clean looking for the duration and the sump hold at least as much oil as a 2140's. They do work most of the time at 2000rpm or above, but still I would not have expected such engines to be so hard on the oil. Both have nearer 7000 hours than 6000 on their clocks and as long as the oils and filters are changed at 200 hours they don't use any oil. Anything over 220 and they do and always have done. Funny things engines and their oil.

Weirdly it hasn't done this until now, hence my thinking it may be linked to VS oil seals due to its age.
The tractor will never get a serious thrashing here, as we do not plough etc, only work is as I have highlighted above, which potentially the flail mower will probably be the hardest long term use.

So in that light, what would be considered a good job to help settle it if that is required?

In what way - what kind of work?

Good question, the chassis plate states 2140, the decals state 2040s and was sold as a 2040s.
Haven’t been to the JD dealer to check out serial numbers yet, so assuming it is a 2140 with replacement decals.

No turbo visible on the tractor, which again is causing confusion.

2040s so no turbo, either had previous turbo problem and has been converted, or front tombstone has been replaced with one off a 2140 breaker. What's the numbers on the engine serial number plate. What does the log book say.?

Log Book doesn't say model type, only engine number / John Deere, Agric Tractor.

The chassis plate: Typ 2140 / Code 214BU + SG2 Cab is 2140, bonnet is 2040s, selling info was 2040s.

It would appear from what The Duck has said previously it is probably a 2140 with Turbo removed iirc.

Is radiator core clear?
Is fanblade clean ?
When was the last time you changed air filter ?

Everything appears clean. It is down to get all oils and filters changed, lubed up and everything checked over to see what is required in terms of wear and tear items etc.
All our kit gets maintained well, as I don't like reliability issues on kit whihc is avoidable - so we try to mitigate things with routine maint etc.
