Re: 402 stocker engine
Not having smoke from the headers simply means there's not a lot of oil getting into the combustion chamber, by the oil rings or the valve stem seals.
Smoke from the valve covers is a sign of blow by, or oil temperature problems. Blow by will actually blow the oil ring out against the cylinder walls, and stop oil from getting by. With good quality modern rings, odds are your problem is the hone, or what you're doing to assemble the engine. Call Keith or Kevin at Total Seal. The proper way to test cylinder seal is with a blow by meter on the dyno, with a Dwyer guage, there's no real substitute There's a video on youtube, by Lake Speed Jr.

Re: 402 stocker engine
Not sure if anyone else ask this. Do you know the tension on oil ring?
The other would be seating the rings. Either on a dyno if in car then maybe get brake pressure as high as you can and run motor in gear as high as you can. If unable to hold in 1st gear try second gear. I had trans brake on my super stocker and it worked well on rebuild. Don't forget to remove rpm chip. Hopefully carb is not leaking when sitting and washing out cylinders. Last edited by Jeff Stout; 04-18-2024 at 11:24 PM. Reason: More |

We have had good luck. However, to be very clear, we use flanged diesel sleeves. I won't use a non flanged sleeve anymore, for anything. Flanged sleeves are a royal pain, especially if your block is already "finished", and you don't want to deck it much, if any. But properly installed flanged sleeves do not move, and do not distort. Also, a good quality sleeve is better material than a production block. Combine a quality sleeve with the modern diamond hone process as prescribed by guys like Keith Jones and Lake Speed Jr., at Total Seal, and you have the best possible cylinder.

Re: 402 stocker engine
The part that doesn't sit right with me is that it sat for 3 years, and somehow became a smoker

Re: 402 stocker engine
I would consider changing the Oil to Maxima break in Oil and then put a load on the motor in the car a couple of times, letting it cool down in-between and see if this changes the breather oil smoke condition.

Re: 402 stocker engine
