So i most likely have a headgasket issue, but I am not sure if I have a piston issue (whether it be rings or the pistons themselves).

Smoke comes out of my breather all the time (idle or WOT, and in between) - PVC is open dump

Car overflow tank would also fill under boost.
Ok so I have sludge in my overflow tank but does not overheat. However my crankcase looks like oil, and I do not see any white substance in there. I'm assuming that when i boost, my head lifts and oil and carbon (which was also found) go into my coolant.

compression test (with seven cranks) CP 75.5mm 9:1 pistons in a d16y8 motor

1 - 190
2 - 200
3 - 200
4 - 200

My plugs
1 - sludge on threads
2 - normal
3 - normal
4 - normal

Im ready to take my car apart soon, but I am not sure if I need to take the bottom end apart.

Any advice?
