L4330 engine problems

Re: engine problems

Have you torn it down to figure out what happened? It could be a cracked head or blown gasket!

Re: engine problems

Might want to go up above your first post where it says "SEARCH" and experiment with a few different words to see if you find some existing links to similar problems.

Often times beats reinventing the wheel, and saves time waiting for someone to respond.

Re: engine problems

It would have been nice to know that you have dug deeper than indicated on the O.P.!

Yes, if you order a new engine from a Kubota dealer it will fit. Now I should a turkey here, but I won't be.

If you order a new engine, you will have to drill holes in the block at where Kubota prescribes. This will have to have pictures e-mailed by the dealer before they even order the new engine.

Thank the EPA for this!

Oil was getting into the water and making the water into a sludge. I replaced the head with new head & head gasket., still getting oil in water. After it sat for awhile I checked the oil & water is now getting into the oil.

Very often people having tractor problems post here before they've gone very far into diagnosis, and replacement of major parts. There is a lot of experience and knowledge here you can likely tap into - but it would help to post more details of the original symptoms, how they developed and changed, (noise, loss of power, smoke, etc). Now that there's water in the oil too, has the engine run long enough to be damaged by it?

Re: engine problems

I don't know if that engine has a water pump or not, but in another recent thread I recommended a product called Block Seal, by CRC. I have found it to be a very effective repair for a cracked block, provided the directions are followed religiously. Someone else mentioned that it may not work without a water pump. And they might be right. But if the alternative is replacing the engine, I think I would try it first!

Not all kubota engines are "the same". There's a few different variants, even of the exact same displacement engine. Lot of times the governors and injection pumps can vary from engine to engine depending on what application it's for. Compression ratios can vary. Exhaust an intake manifolding can vary. Turbo vs naturally aspirated blocks-they're different too (turbo blocks are drilled for the oil return). Water pumps can be different depending on what it's going into or coming out of (if someone was to buy a donor engine). Crankshaft pulley. Etc.

If you end up having to replace it, keep those things in mind. Kubota has a model number on each engine, for instance V2403-DI-E2MA, and each number/letter has a meaning that designates it's application among other things.

I'm one of those who, when I went into the business, I thought many of the Kubota engines were interchangeable. Had a guy with I think an L2900 that needed an engine (broken crankshaft). He found the same displacement engine that came out of a reefer unit. I go to install it, bellhousing different. Flywheel different. BUNCH of stuff was different. I had to swap the stuff from his old engine, got it bolted to the tractor, started it and find out that it runs 1800 RPM continually, no idle. Thats how I found out that the governor is different, and the linkages. And the injection pump as well. By time it was all said & done, the guy put nearly $3000 into a used engine to make it "work" on his tractor. At that time, brand new engine from Kubota was $3400.

Let us know how the sealer works...I'm curious.
