1998 Suzuki King Quad Oil leak


Recommended Posts


Hello! I'm hoping you can all point me in the right direction. Last fall my wife got our 1998 King Quad stuck in some mud. Before winching it out, I tried putting it in low and working it out myself. It was definitely under a load and then started smoking. As I winched it out I noticed a trail of oil coming from the skid plate area. I parked it for the winter and got it out yesterday to drive it to the garage. It immediately began pouring oil out again and smoking pretty bad. I have attached a picture of where it's leaking from. Any help would be greatly appreciated!

Welcome to Quadcrazy, it appears from the picture that your head gasket is blown and hopefully not a cracked head.  If you reved it as high as you said you did then it’s possable more damage was done like a valve seal but I don’t think so. You may get lucky and just need a new gasket.  I would spray a soapy water solution where the oil was coming out and slowly crank the engine with the spark plug wire off so it does not start. You  should see bubbles if its coming from the head where you see the oil leak.

Thanks, Frank!  I will try that trick this week and see.  I did some research and it looks like it's "fairly" simple to pull the head off, right?  (I'm a shade tree mechanic, so I'm fairly comfortable).  

Yes, the plug has a decent amount of oil on it.  Actually, now that you mention it, it was running a bit rough last fall and I changed plugs. It had some oil on it then too.  Is that a sign of a bad gasket too?

Yes most likely a head gasket but this happens some times bc you loose a valve seal and the head gets oil inside the cylinder and during the compression stroke the gasket blows out. Have you done a compression test? Hopefully not the case here and just a gasket swap. And yes generally easy. Download the manual and get fimillar with the engine as well as YouTube the work. Between that and Quadcrazy member support I think you will have it up and running in no time. 

Post some more pics when you tear into it if you can please.

      My king quad 700 runs rough when cold then won't start some times but not often when it's hot. And occasionally smoke's a lot when it's cold I'm guessing that's rings but I'm worried unless it's causing the other problems
      All help is appreciated thanks

      3500lb, synthetic rope lead and everything needed to install for........................................ $89 bucks!  I'm installing one on my '01 Bombardier Quest and it looks like a legit buy. If you have a RK nearby & you need a winch you might want to swing by before they disappear.

      If you had to choose one mod that you couldn't live without, or had to recommend one what would it be?

      2022 Sector 550, 414 miles on it and the gas gauge reads empty.  I topped off the gas and it didn't change.
      There is no fuse that I could find.  No access at the gauge cluster.
      Wiring on the top of the tank looks good, properly connected.
      Could the sending unit in the tank be stuck or broken?
      Has anybody removed the tank lid?  Any tricks?  
      Any other ideas?
      Thanks for any help,
