Rings for H

No matter how I cut it, it is sucking oil in the #4 cylinder and I am going to go in there and check it out. I have about 70 # compression on that cylinder...I think way too low..and it smokes a little. I take the plug wire off #4 and it quits smoking...so I am burning oil.

I dropped the pan tonight and removed the head. I am sending the head out tomorrow to get the valves ground while I am doing the other stuff.

I have no motor experience but I learn quick.

Here is what is going on inside my head. Tomorrow I intend to take just one Piston out, #4 so I can see just what ring set goes in there...best I can tell, there are 2 or 3 different types and widths depending on the piston.

Here is the question that I need some guidance on.

One hole at a time, I need to understand the inspection procedure to determine the sleeve wear to determine whether it is in tolerance for a new set of standard rings or whether I am a candidate for new pistons and sleeves.

If someone has experience with this and can give me the A,B,Cs, as I said, I can follow directions.

As a note, I have good oil pressure, and the engine does not knock or rattle...so, I will not be messing with the bearings on this go around. Just going to put APPROPRIATE new set of rings in it--if, keeping my fingers crossed, possible.

One VERY VERY VERY important thing to do is to check for sleeve/cylinder taper. I had a 4.3L chevy engine I tore down to replace the seals cause I though the head gasket was blown. I replaced all the seals, just did a wiggle test of the pistons cause i wasnt looking to mess with them, just wanted to make sure they werent really loose. Well I only checked them in one spot, turns out later right before putting the head on, i had moved the crank to time it so the pistons were nearly 180 from what they were, and turns out one of the cylinders was serverely tapered. I had it almost all done, so i just through the head on and put it back in the truck. It burns oil in that one cylinder now, almost 1 quart for every 100 miles. I recycle my car's old oil that way and its just a hauler truck, not a daily driver. Also gotta replace the sparkplug every 1000 or so miles, but I got a boxful of those plugs, so It's not a big deal, too bad its the hardest one to get to. If I had known at the onset of the regasketing, I would have returned the gasket kit and threw in anouther 100 and got a used engine to throw in it. Hindsight is 20/20 and I leearned a valuable lession that time. Be sure to check at the top, middle, and bottom of the sleeve. I know I'm making a long post, but it would suck for someone to have an experience like I did, Not a good day that day, I tell ya.

I would also make sure u prelube the new rings/piston with some oil or assembly lube.

They do sell individual one piston/sleeve kits if you just need to replace that #4 p/s. Hope I helped a little.
