I have a 1991 toyota celica st with the 4afe engine. I recently did a swap of another 4afe engine. the only issue im having now is that after about 1400 miles of driving i have burned half a quart of oil. I did have the rpms up past 4500 on the highway on a beach trip so that may have contributed to the burning. The owners manual said that its normal to consume under high speeds etc. but is this a normal amount or should i be concerned? My old engine was burning half a quart a week. I checked pcv but im gonna replace that to be safe cause its a cheap part. Do you guys recommend a high mileage oil like maxlife? All cam seals, oil pump, rear main and valve cover seals are brand new also.
