Car had been going well, but approaching red line it stuttered and big cloud of oil smoke. Hoped it was burping out a bit of overfilled oil, but it never got better. Compression test (regular tester with valve core removed) showed rear rotor at 110psi on all three faces, but front rotor was sorry looking at 40, 60 and 80psi. It still starts fine and drives at low revs (if a bit lumpy), but smokes like hell at high revs.

Main question is is it even worth trying to clean with water/Seafoam/BG44K or should I just face facts and pull the motor?

Looking through the plug hole, all 3 apex seals look intact and springy. What would cause such bad numbers on all three faces? I'm fearing for my end plate(s).

(I posted in DIY section by mistake - I'm not making multiple identical posts to be a dick, just due to not reading what the diy forum was for!)

 

40, 60, 80 is low. That rotor may have eaten something to cause all faces to be down. At this point you could always try Seafoam, likely won't make it worse. Likely the motor is gonna come out either way.
