What is the year of your Toyota and how much oil is it useing per 1000 miles or per oil change??? The 22RE pre 1987 I think hat an overly agressive oil ring and with alot of down shifting you would use alot of oil. THey fixed this in 1987 0r 1988 I think with a heat treated stainless steel oil ring that had less tension. It is unusual for this engine to use much more then 1/2-1 quart of dino oil per 3000 miles unless it has been driven harder then heck with out proper maintence. They will usualy make it to 200,000 with no smokeing or excessive oil consumption feed a diet of 20W50 in warm months and 10W30 dureing winter. They will make it to 300,000 on this diet. If it has been driven hard and ran on thin oil the thrust bearing will start to knock at 200,000-240,000. The transmission if not properly servived will usualy start to jump out of gear at about 150,000-180,000 miles My family has owned about 7 22RE equiped Toyota and I used to race prep 22RE's in celica's and truck. I was a BWM and Toyota Tech. In spite of what is on the cap on the newer Toyota's they do not live as long or as happy with 5W30 dino oil. The 22RE is in my opion they most durable engine ever put into a gasoline powered car or truck it is even better then the slant six!!
