I have changed a few cylinder heads under warranty for this type of problem. The exhaust valve guides wear, this causes the exhaust valve to seat badly, giving low compression. if one cylinder compresion reading is more than about 50 psi below the others, then this warrants head removal. It is quite a job, due to the fact that the camshft id chain driven. If you are up for it then once the head is removed, poor liquid into the exhaust ports and see if it leaks out through any of the exhaust valves.

this is a turn in caliper, meaning that as you try to compress the piston, you also need to rotate it clockwise. you can buy tool for this at nearly any parts store, and is fairly inexpensive.

Testimonial: "Thank you for your assistance. I found out the turning piston part by mistake, a day after I posted the question, when I tried to use a G-Clamp."
