oil filter 1610TS

[Rambo]

What is the correct oil filter for a iseki 1610TS? I heard that using the wrong oil filter could cause problems. In which I have oil coming from oil cap. I changed the oil and notice after running for about 5 min. it started coming out of oil cap. I don't know if this would cause it or not.
Thanks,

If oil is coming out the fill opening it could be due to excessive blowby due bad rings.

Oil is coming out the breather cap because the rockers and rocker shaft are worn. I have the same tractor, had same problem. Seems to be somewhat common with this Isuzu motor. I installed new rings first but that didn't help. The only way for oil to get back down to the pan in these Isuzu motors is down the pushrod tunnels. Not too much room there and and any excess oil on top will start to fill the valve cover. Fortunately it's an easy changeout. You just need four new rockers, a rocker shaft, and the two plugs that go into the ends of the shaft.

Yah, I guess you mean the rocker shaft tower bolts. I'lll have to look it up in the manual and get back to you.

Randy, the rocker shaft bolt torque value is 13 lb-ft. In my case I could see oil flowing copiously from the front rocker/shaft interface. I knew that wasn't right. I confirmed the problem when I took the rocker assembly off the motor and found the rockers did not have a good precision fit on the shaft (i.e., loose). Also the underside of the shaft had wear at the front rocker location.
