im gonna say rings.
best way to test...
do it cold since thats when you get odd numbers. make sure that while youre cranking it over, you have the gas at WOT. on the low cylinders (#4) add a little bit of oil down the sparkplug hole, crank over a couple times, then retest. if the numbers go up significantly, then its your rings. if they go up a little bit, but arent even close to the other numbers, then its your valves.
