2008 diesel Engine oil leak

Recommended Posts

I’m trying to narrow down a leak.  It may be the oil pan.  
how difficult to repair this?   Is there a gasket or?

Howdy. i've been through boerne once, made a stop at the 'Cave without a name'. pretty neat.


a service manual will also be  very very helpful once you diagnose the problem and go to fix it, https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313&_nkw=2008+diesel+3010+mule+service+manual&_sacat=0

does it  leak more when running? or only leak when sitting?

looking at the parts diagrams,  it appears there isn't a gasket for the oil pan, 2007 and prior models have it, but not 2008, they probably used a RTV/silicone compound. but there is a  timing cover gasket , and another gasket for the timing gear case, as well as crank oil seals, so those are all possibilities.

 it's easiest to diagnose oil leaks with a clean engine, so i suggest cleaning the block as best as possible with parts  cleaner and some rags. there are also kits you can buy with a UV light and a bottle of dye you put in the oil and the UV light makes the dye glow. that makes the process easier.

Thank you!  I’ll get it cleaned up and look into that leak detector.  
next is a new water pump.  Good time to do that.

      I did a fairly major overhaul on my HS 700.
      Had some issues with bending valves...I believe found the root of the problem. Replaced the timing chain (old one was  stretched 3/4" longer) 
      Got everything back together....but had a fairly steady oil leak from the stator cover.  I tightened the bolts as much as I dared, they were all torqued to spec at assembly but  when I noticed the leak I gave the bolts on either side of the leak an extra bit of tightening to try and get the leak to stop but no luck.  
      Had a bit of a brain wave and did some googling, seems like a few other folks had  a similar idea. I cleaned the area with brake clean and ran a bead of crazy glue down the crack. Let it soak in and dry and did a second round. Let it dry and fired it up, voila...no more leak.
      Will see how this holds up but it saved me having to rip it all apart again , hopefully this helps someone else.

      I just bought a 2019 Odes Ravager 1000.  I took it in for a check up at my local offroad shop.  They changed oil and oil filter.  There's a leak around the end cap.  Has anyone had this same problem?

      First off the Massimo has been running great. Hasn’t missed a beat since I worked on it last.
           I’m pretty sure this has been an ongoing issue even before I got it. Towards the front of the crankcase, right of driveshaft coming out I noted a lot of oil buildup. I cleaned it up really to see if I could identify where it was coming from. It looks like there’s a seam where the two sides meet and that’s where leak is originating from. 
           From what I find in the service manual it doesn’t look like there’s a gasket here. So would anyone know how this seam prevents oil leakage? The next question is how would you correct this leak? I’ve read where you don’t want to use oil leak stopper as that will most likely cause slippage on your wet clutch. Any thoughts? 
      Thanks, Harrison

      I recently bought a used Kubota RTV900 with a plow attachment to take care of a long, steep driveway this winter. I think it’s a 2006 and it has about 460 hours on it. The previous owner told me when I bought it that it needed an oil change but I know nothing else about how well it was maintained over the years. While going through the items in the maintenance schedule I discovered a problem with the coolant system. The coolant reserve tank was completely empty so I filled it and soon after noticed a spot of antifreeze on my garage floor. I had never noticed a leak before. I took the protective panel under the radiator off the bottom of the RTV and could see that the radiator itself, the drain valve, and all hoses and connections were dry and tight as far as the hose going into the engine block. I then took off the next protective panel that is right under the forward part of the engine. The engine-facing side of this plate was covered with a mess of oily debris that had to be scraped off and the engine itself was pretty dirty also. I cleaned things up with some paper towels and ran the engine to see if I could spot any leaks. After running the engine for only a few minutes, I saw a drop of coolant on the side of the crankcase right behind the starter motor. I wiped it dry, started the engine again, and the drop re-appeared after a few minutes. I was expecting to find that maybe the water pump was leaking, but I don’t see how that would cause the coolant to appear so far back on the side of the engine block. I can’t see anything else that might spray coolant onto this area. If the cylinder block actually has a hole in it I would expect I would see a lot more problems than just a slow leak of coolant.  I am fairly handy but as I’m sure you can tell I’m new to engine work so I thought I’d see if anyone could help me diagnose this problem. Thanks.
