this did fix the problem temporaily but..............
after some time after this post this motor blew out the rear seal due to super excessive blow by.
The story:
After another fun wheeling trip and high revving the crap out this motor it started to push oil out of the crank breather. it was holding a steady 80-100psi at cruise and I was not sure if I could make it home cause I was on my way home from portland. Well somewhere around Chehalis the oil pressure went passed my gauge limits and blew out the rear main and I called a tow truck since the motor was toast.
When i dissassembled it I found a deep cylinder ridge and all the top compression rings where shattered all the way across.
The cool thing I found out at the time of dissassemble is the motor was a 20r/22r hybrid the head was ported/polished/with OS valves
A little later I scored an good 84 22re running motor and took it apart it was ready for a rebuild but needed no extensive machine work.
A few weeks later I rebuilt the hybrid with the old suped up 20r head and did a re-ring and bearing job on the 84 bottom end and its the best R series motor I have ever had. It cleans the center lugs off my 36" TSL's.

well you'llbe able to see it at the yota show but as far as high revving this torque beast on the trail IDK maybe around thanksgiving. times are super tough right now for me and my bank balance is playing with the red too often.
