Hey 4runner friends. I need some expert advice on what might have happened. I bought a beauty 2000 4R 4wd SR5 with only 113k mi. on it.

The rig had been sitting for over 8 months after the owner died and the battery was dead. I checked the oil and it was clean and yellow even though it was almost due for an oil change. I jumped the battery and it started right up. After idling for a few minutes, I drove off to home about 45 mi. away. The rig ran great and everything worked perfectly.

The problem is this: After only one tank of gas, I noticed the oil level was down 1/2 qt. I put oil in it and drove it for another tank of gas and noticed it was down again 1/2 a qt of oil.

This 4R was taken very good care of and I had all the service records to show it. This 4R is in beautiful condition and it is obvious that it was never abused. It has the 3.4L engine with auto trans and is S.charged

My question is what could have happened that would cause it to burn so much oil all of a sudden? Did letting it sit for so long let the rings dry up, or maybe the seals? It doesn't smoke at all...even a little bit and there is no sign of leaks under the rig after sitting for 2 days.

I am very bummed out now. I thought I got a great deal on this 4R, but now it look like it has major engine damage from sitting so long and then starting it up. Why else would it burn so much oil? Any ideas?

What engine?

 

The engine is the V6 3.4L 34, 24 v with S.charger. There is no smoke at all coming from exaust pipe at start up, or running and no dripping on the clean cement below it where it is parked. The engine starts great and runs very smooth. Gas mileage is not that great btw. The oil is very clean and has always been serviced every 3k mi. along with everything else.

Is there a chance that the seals could revive after running it for awhile, or is this a major problem needing and over haul? Any thoughts on this would be very much appreciated. Thanks

I had a 2002 ford lightning that was supercharged, it was common for them to suck a little oil through the pcv valve into the intake, so if your getting on the throttle to hear the super charger more than likely you pulling some oil into the intake. what i did to stop the oil from going into the intake was install a small oil seperater to catch the oil.
