Default Blue smoke on start

95 accord dx 2.2 mt. It smokes a ton of blue smoke on a cold start. During the rest of the day theres no smoke. I've cleaned the pvc, change the plug tube seals, top and bottom, valve stem seals, valve cover seal, set the valves, run seafoam and she's still smokin. Not sure where to go from here?

That is usually a sign of worn valve stem seals.

Did you remove the valve springs and swap out the stem seals with the head installed or did you remove the head?

How did the valve stems look once you removed the springs and old seals?

When you stop the car and shut it off, check for oil in the PCV hose going into the intake.

Did the stem seals with the head on. The stems looked pretty good. a bit of shmoo but nothing to bad. The pvc line looks almost clean. Can't see how the pvc would contribute to that much smoke.
Looks like my thermostat needs replacing. It seems to be stuck open. Maybe its not getting hot enough to burn off the carbon?

If you can't figure out the problem after you already done all the work that could lead to blue smoke on morning start up. The only thing left for blue smoke could be the cylinder head valve guides. Worn valve guides also lead to blue smoke like worn valve stems.

I just bought this car on the cheap. It was smoking on startup and had the plug wells and plugs full of oil hence the cheapness. Thanks to the interweb world I fixed the known issues. Still smoking after all that but running so well, I had feeling the car just needed to be driven as it had sat for some time. Well low and behold I start it up this morn and NO SMOKE! Looks like it needed some time to burn off the residual oil that was in the cyclinders and im sure the seafoam treatment, it got, loosened up some stuck rings.
