( warthog ) i see where your coming from.. it seems like there might two probs?
4cyl is not the greatest and the po301.. both the same? two differint probs? idk..
i think you should try this and see if it moves over... also the wet compression test and a cylinder leak down like warthog said..

Still wondering about the paper test at the tail pipe being sucked in.
i bought a 95 keep xj manual and looked at engine surrounding area for oil leaks. The guy assured me there were none. I drove it around the block and checked 4 wheel dr ect.. I popped the hood when I got back and looked again nothing bad seen. the jeep started leaking lots of oil out of dipstick tube after driving for about 45 minutes and higher speeds. I replaced the CCV and did a compression test.
My numbers were:
Cold-
#1. 97PSI
#2. 100PSI
#3. 99PSI
#4. 108PSI
#5. 105PSI
#6. 102PSI
Hot
#1. 103PSI
#2. 118PSI
#3. 111PSI
#4. 112PSI
#5. 120PSI
#6. 114PSI
I've read to multiply highest by .15 and deduct that number from your highest reading and if in that range your good. 103# is in the range but barely. In a 4 hour drive I'm losing 1 quart of oil and creates a fire hazard smoking awful. Any suggestions? I also pulled the oil cap off running and it had a vacuum at idle. Any suggestions are appreciated thanks
