First I’m going to start off by telling you how the problem started.
I have a XY Ground Pounder with the 1100cc Chery Engine; I sunk it in a mud hole and had water up middle ways of the muffler; about 10 seconds of being stuck and hitting the gas all of a sudden the motor started making a tapping noise that sounded like it was coming from the head (the buggy never died while I was stuck on the mud hole). I finally got pulled out and had to proceed to drive the buggy out the rest of the trail back to my truck (buggy still making the tapping sound and I lost about half of my power and had to keep the buggy going at around 4,500RPMS).
I got the buggy home and first thing I drained the oil and dropped the pan to find water, dirt and metal shaving in the oil. I proceeded to check the rod bearings and mains; they had very little play but had a lot of wear; I also took the head off and inspected everything and took the pistons out everything looked fine up top. So I ordered a new crank, main bearings, rod bearings, head gasket and bolts; after waiting for a month for the parts to come in I finally got the block and everything clean and put the new parts in and torqued to spec. I got it all put back together and new fluids, plugs and filter put back in and everything aligned and put back in time while TDC. I started the buggy and instantly it’s still doing the same thing; so I took the head off and inspected the springs and valves but everything seems to be good. I also did a compression test on each cylinder with great readings.
Has anyone ever had the same problem or know anything?
Thanks for taking your time to read.
