Other UTV SxS Forum

They are hitting every day. I’m cleaning up as I catch it. I’ve gone back to requiring the first post from new members to be approved. Seems to be catching these created topics around Temu coupons/spammers.

Thanks, Alien10, I need all the luck and confidence I can get. I'll get it one way or another. Well a bit more confused now. I'll list what happened in order. 1. Opened the bleed screw on goose neck on top of cylinder. No antifreeze came out. Couldn't see antifreeze in hole. Screwed bleeder back on. 2. Opened radiator cap. Coolant was a little low. Topped it off. Left cap off. 3. Opened the bleed screw and left off until antifreeze came out. 4. Topped off radiator with coolant and put cap back on. 5. Made sure both of the ball valves were on. So coolant had a least resistance path through the engine. 6. Started engine and let it run for about 10 minutes. No smoke came out of muffler. Did have some "air" come out the hose that broke off the air oil separator.  7. Removed spark plug, disconnected the coil and fuel pump. Installed the compression tester. Held gas pedal to the floor cranked the engine. Got 130psi. (Didn't do the pedal thing during the 1st testing). Lite a cigarette and started the stop watch on the phone. Listened and felt for air at muffler and air oil separator hose. Nothing. Raised the front of UTV about 6 inches. Removed radiator cap. There was a little pressure. But didn't see any bubbles. I drained the overflow jug back down to full mark.  8. So 12 minutes has passed. Compression gauge is reading 125psi. 9. After 16 minutes, compression gauge is still 125psi. I bumped the engine in case the piston is in some way sealing the gasket that I think is compromised. 10. Watching the radiator, still no bubbles, after 20 minutes. Compression gauge is still at 125psi. Can't hear of feel any air at muffler or crank case hose. I release pressure on gauge. Hold gas WOT and crank engine. Compression gauge goes up to 125psi. Battery is weak. Drops to 10.5 while cranking and only 12.1 after. 11. After 30 minutes the compression gauge still at 125psi. Couldn't hear or feel or see air escaping anywhere. Radiator still topped off. No bubbles. Opened the bleed screw. Had coolant weeping around threads. 12. So now 40 minutes has passed from cranking the compression tester the 1st time today. Gauge still at 125psi. No bubbles, or anything.  13. I release pressure from gauge. Removed gauge. Install spark plug. Reconnect coil and fuel pump. Left machine in air. Started machine.  14. Let it run to get operating temp up. Variating the RPM from idle to 5k. Did get some blue smoke, but not a lot. Did have steady blow-by out the crank case hose, even with high RPM. Didn't see any bubbles in radiator. Put cap back on cause coolant started rising when engine temp started to rise. Didn't see any bubbles rising in the overflow jug. Loosen the bleed screw and no air came out. It just weeping coolant. Raised temp to about 150°. Still no bubbles in overflow tank. 15. Turned machine off. Left front end up in air. Will check everything again tomorrow, Sunday or Monday.    At this point looks like there was/still some air in the coolant system. As motojoe, Alien10, and Joe Breaux has said all along. But I'm not 100% sure if head gasket is blown or just had air bubble. I'm going to raise the front some more. Then do the same testing and see what happens. As the great Sweat-Hog, Vinnie Barbarino, once said, "I'm so confused." I feel better now. 😂

Merry Christmas to you too.  Be confident, you can get this thing back in service.  Best of luck. 

I've been checking on shops that would work on this beast in the near future. So far I haven't had any luck. I checked and there is one of those storage unit places that will allow me to rent a unit and work on the UTV there. Price isn't bad. 10x10 unit for $40 a month. As soon as he gets a spot open. LOL No electric, so I'll have to use my generator. Parts, cylinder, piston, rings, wrist pen, gaskets etc will be about $300-$350 from Amazon or eBay. They have the parts for about $80-$100 for the older engine. But seems those only fit the 2015 and older. Mine is a 2021. Still waiting on the right time and place to tackle this beast. With that said. There isn't an auto parts store with the loan-a-tool around that has a combustion leak down tester to loan. Only 2 close by. Nor do they have the combustion gas detector either. I checked on Amazon and can get the leak down tester for about $35. It has good reviews. Can get the combustion gas detector fluid for $11 at harbor freight. Maybe parts store has the detector fluid. I haven't checked. But parts store doesn't have the bottle/tool to put the fluid in. But from what I've read. All that needs to be done is have the gasses pass through the liquid. So maybe I can rig something. Cause there are bubbles going into the overflow jug. Just remove that hose and place in an empty clear water bottle. And let it bubble up through some detector fluid. Alien10, I don't have an air compressor or any way to apply pressure to the cylinder except with the compressor tool. The only air compressor I have is one of those 12v that you plug into a car cigarette lighter socket. My brother borrowed my 110 pancake air compressor 5 years ago. LOL I use battery impacts when I need a little extra ump on something. As you suggested, I could put the compressor tester on. And use it to see if I have bubbles. That probably what I'll do today to get out of the house for a minute or two.  Maybe run to parts store also to see if I can get the gas tester fluid also. Also just a FYI, on the driver's side of engine. Where the hose connects to the engine case. There is a hose that goes up to a type of air lock, a black plastic piece. That acts as a PCV valve. On the bottom of that piece are 2 nipples and 1 on top. The top has a hose that goes to the air filter box. So blow-by gasses don't enter the cab. One hose on bottom goes no where is is closed off at bottom. It's used to collect oil to keep it from dripping of machine/ground. The other connect to hose going to the case. That nipple is broken. Called an air oil separator, $15 on Amazon. So that is going to get ordered and installed soon.    I'll keep everyone posted on the progress of this beast/issue.  Wishing every one a Merry Christmas and a Happy Hangover.   Kilgore
