Is my compression ok?

Here is a video I just took of me compression testing my car. The car wasn't completely warmed up, but wasn't all the way cold. I guess it looks like I have a blown apex seal??? What do you all think? The car ran fine, then it didn't run for a year while I worked on the turbo project, now that I've gotten it started, this is the compression results. The front of the car is jacked up, I don't know if that makes any difference...

The first 10 secs are of the rear rotor, the second part is of the front rotor....

thanks in advance,

Tom

the first rotor u did looked fine,

but the last one however appears as if you have 1 blown apex seal, as you notice it is skipping pulses...

its prolly just blown, and not a stuck seal... but if u wanna be 100% sure, take off the ehxuast manifold, get under car , use a mirror and shine a flash light into the ehxuast ports, then turn the motor over by hand, and inspect each seal individually

if ones cracked or real stuck or missing, then yeah its bad

sorry!

Definitely a stuck seal, because I felt it when we took the manifold off.
