Please help I have a Massimo 400 buck that has an oil leak. The oil is leaking on the front side of the motor. It leaks out of a u-shaped steel pipe that has two banjo style fittings on it. I have tried using RTV and different banjo washers and have had no luck. It drips about one drip per second while it's running. I can't find parts for it at this time.

I take it the leak is at the fitting? Is it both fittings? Did you maybe try some plumber's tape? Wrap that around the threads on both fittings and see if that helps.

I have tried two sets of rubberized o-ring crush washers off of Amazon and both of them have leaked. Not sure what to do next other than to keep adding oil and keeping the dust down around the property, lol! Very frustrating.

I was able to get a closer look with a camera snake and I found that my leak is coming from the cylinder gasket and not the oil lines that I have been screwing with. Any ideas besides taking the motor apart to fix this(considering trading it in because of the lack of parts out there)

By "cylinder gasket" do you mean the head gasket? Keep in mind that these engines are usually a clone of another manufacturer, such as Yamaha, Kawasaki, etc. If you do some research you may be able to find out what other manufacturers out there are using an identical engine. This can lead to parts that you originally thought were no longer available.

I'm sure other members here can chime in and offer some help with that.

      UT400 First Oil Change Overfull Milk Chocolate What to Check
      By Homeowner A
      Picked up an essentially new 2022 UT400 with 9 miles on it.  Decided to change the oil because it's probably never been done.  Pulled the dipstick and noticed it was overfull then went and pulled the drain plug and took off the filter and it was like brown water running out.  What should I start checking?

      We have a 2018 Cub Cadet Challenger 400 and I found this Internally Threaded Bolt with a 10mm head size laying in the floor of the shop bay here on our ranch where we park the Cub Cadet.

      Coleman UT 400 Garage?
      By Homeowner A
      I have a Coleman UTV 400 and looking for something to store it in.  Preferably something vinyl or plastic with its own base that can stand alone outside and house the UTV.  I think the dimensions of the UT400 are around 106" long 52" wide and 74" tall. 
      What should I consider that won't break the bank?

      2023 t-boss 550 belt slipping and found oil in belt housing
      By Cory J
      Belt started slipping when I used it in high gear. It works okay in low unless I'm trying to power it up a hill and then it slips.., Ordered a new belt and went to change it and found a good bit of oil in the belt housing. Has anyone experienced this? Belt looks fine. Only have 300 miles on this thing..

      2017 Cub Cadet Challenger 750 hisun junk motor
      By hisun junk
      As I tried to do a conversion with the Yamaha 660 motor, I realized the 660 was never fuel injected so it would not work for the fuel injected hisun motor swap. But the good thing is the hisun 750 motor is a clone of the 660 Yamaha but with the components for the fuel injection (cam/crank position sensor). So that left me with a new rebuilt Yamaha 660 and still a broke 750 hisun motor. I took apart 750 think the timing chain had broke from all that I've heard about these motors. The chain was not broke, but just off cam and crank gears! The chain tensioner was at fault!  I've ordered Yamaha 660 replacement parts, chain, two exhaust valves (which got bent when chain came off while motor was spinning) and seals. The piston has 2 little nicks where it had hit valves but no damage otherwise. The head is being redone at the machine shop and I'll be putting it back together in the next couple of weeks. Also I finally tracked down a Service Manual with all the info on the 550/750 Challenger.
