i dont remember the what th package said the just stuck my old rings in the package and stuck the new ones on the pistons for me.. but i still had to face them the right way. they should be standard size cause all they did was hone it to rough up the walls. all the plugs are the same when i pull them and i can see little bit of oil on the tops of the pistons whith a light when i pull the plugs out. as far as gaskets i dont think there are any and at least it doesnt leak oil. so far i only have 150 miles on the carsisnce the rebuild.
---- i live in bridge city texas south east really close wehre it meets louisiana think thats close enough to the spelling. also you might kno beaumont im about 15-25 minutes south of that depending how fast you drive lol
All I can say is I have been where you are now and I am sure its solvable.
Well since I wrote that last post I have a bad feeling you have a compression problem.
I think its time to do a compression test. Do you have a tester ?
If you can try really hard not to use hardly any throttle opening when you drive because if this is the compression rings the blow-by will overheat them and they lose the spring that keeps them against the cylinder wall.
OK if its standard size you cant have the wrong size.
They can be put in upside down, and you should have aligned the gaps around the piston.
When you assembled pistons to the block did the rings noticeably stick out from the bore ? and was the spring tension noticeable, usually they are tough to get back in the cylinder bore.
what was the estimated wear in the cylinder top to bottom? Who measured this and how ?
I was hoping you were closer to Dallas area, there are a lot of Nissan guys on the forum here from Dallas.
Ok I will look at the FSM for ideas.
