95 runner consuming a lot of oil.

Need some advice. I have a 95 4runner 3.0 that is going through a lot of oil. On a 4 hr drive covering roughly 300 miles at 60-70 mph, I consumed close to two qts of oil! No leaking. I would notice that much oil. Also absolutely no black exhaust at all?? Or any discolored exhaust at all. Last year I replaced the timing belt, front main, cam seals, valve cover gaskets. My rear main is leaking a tiny bit. No oil under truck after drive or sitting all night after drive. Is it possible this much oil is being consumed without a trace?? If it’s getting past the rings this bad is it a time bomb? My fam and I drive it for three months out of the year down in Arizona. Everything else runs great and still feels like plenty of power.

 

Although they'll start using oil after awhile that sounds like a lot. I put an easy quart in between changes in my Honda (every 5,000 miles.) Mechanic told me their known for using oil if I'm not noticing leaks and have no smoke at startup just keep adding it. They will use more on the highway but again your putting a lot for 300 miles. I've got 148,000 miles on the Honda, also a 6 cylinder.

 

Just drove it another 300 miles. Added two more quarts. Changed oil to 10-40. Drove an hr to store and hr back and was down a full quart! Haven’t had a chance to check compression but everything runs so well. Plenty of power. Absolutely no smoke. Change valve covers last year and probably have 1000 miles on a new pcv valve. I did notice the pcv hose was a little linked so I ordered an oem one that is molded to the sharp angle. Hopefully that is it. This thing is eating oil.
