    Changing piston rings?

    The BPT is burning oil in 4th cylinder (spark plug soaked in oil)
    Is Changing ring set will completely solve problem , cause there must be dammage to sleeve to?
    Is that only patching the problem? .....because im still thinking about oversizing all cylinder and puttin brand new stuff in stronger(forget piston, moly ring)
    My bpt is aleredy modified and i dont want to do this again in 2 years

    If you change the rings, you have to at least hone and measure the cylinder walls.

      Have you done a leak down test on the motor?

        Have your cylinders mic'd to make sure they're dtill in spec. If they're still in spec and you can still see the cross-hatching then you don't have to have it honed. Honing it will make it take longer for the rings to seat, and you'll have extra metal shavings in your crankcase. I've built tons of engines that way with nothing but good results, even though everyone says it's ridiculous. The cross hatching will seat the rings almost instantly, as opposed to having to wear down the hone first. You still need to break them in, it just doesn't take near as long.

        The main things you need to pay attention to when putting everything back together are torque specs and tightening sequences. Having a manual with you through the rebuild will help you more than you know.

          So, mesuring spec and changing ring set does need to take motor out?
          What is leak down test?

              Yes, you'll have to take the motor out to have it rebuilt.

              A leak down test will tell you if your engine is holding compression like it should in each cylinder. Are you sure it's your piston rings making you burn oil? A worn out turbo can also leak oil into your intake that will caue smoke coming from your exhaust.

                if you havnt started on this yet try something for me. itll cost about 10 bucks


                get a 2 cans seafoam and a long funnel

                pull plug wires and plugs
                hand crank engine (or bump over) untill all cylinders are even.
                Pour even amounts of seamfoam in the cylinders

                Put plugs back in hand tight
                let sit 1-2 days

                plug plugs put towel over Valve cover.
                crank enging several times to get seafoam out

                once your sure its mostly blown out put plugs back in and run caruntill white smoke is gone.

                  Julee and i rebuilt her motor in her car we knew the oil rings were not working and the car smoked all the time when cold but had plenty of compression

                            You shouldn't be touching any internal part of the motor.
                            Get a used long block and have a shop rebuild it.
