Ok guys, here we go. I pulled the head - take a look what I found

I took a look at the injectors last night and couldn't see a difference between any of them. I'll get a better look in the daylight today if I don't get rained out.

Scrape it clean. i dont favor the scotch brite method as abrasives get into everything.

A ridge reamer is for removing metal off of a worn cyl wall so you can get the pistons out without the rings jamming. If it's that bad, you might as well go all the way and rebuild it. If it's only carbon, it will scrape off easily with the edge of a knife, razor blade, etc. Be careful not to scratch up the bore.

That would be silly, considering how much work it is, and that all rings have suffered the same heat. Since you will have the rod bearings off,(make sure they go back right) inspect them for any bad things, and pull out the center main too. Better to get bad news now than after re-assembling it with new parts.

Thanks for the reply Paul,

What is the center main?

Thanks,

Bill

Actually Bill, I was just planning to replace the rings on this cylinder since the others were not giving me a hard time. Is this bad?

Bill

Add one hour to replacing the rings on one piston, and sleep better.

LOL, cracking me up Bill

:-)

Could it be the Fram oil filter in the cylinder4.jpg pic?
