If the solution really is just the PCV valve, it is only ~ $10 item. PCV (positive crankcase ventilation) system siphons the vapors from the crankcase and routes them into the intake manifold so they can be reburned in the engine. It's just a little black valve that attaches to the valve cover. Some have claimed this has worked for them (this valve needs to open up at high speeds). I'm not convinced but I think it would be worth the $10 to try it. If that doesn't work, then yes it appears that your repair will involve either the new valve covers that they have made for the older highlanders or the actual heads with new valves. Best of luck. If you do choose to replace the PCV valve and it works, I'd be interested your results.

We also own a 2001 Toyota Highlander that has the same problem of using a lot of oil. I was very interested in your solution regarding leaving the oil cap off and replacing it with an Edlebrock air breather. May I ask what the part # is for the air breather? I would like to try this solution, thank you.

Did you ever have any luck finding out how to get hold of the Edelbrock air breather for your Highlander? I have an 02 with the same problem. I bought it new and have been meticulous about oil changes and such. Very frustrating! I have also noticed much higher oil use on longer, highway speed drives.

My 2001 Highlander is tha same as yours. I am the second owner of this suv.
Current milage is about 166,000km. I found when I drive the speed over 120km/hr, need around 2 quarts engine oil for every 300 km. If the speed is less than 80 km/hr, the engine oil consumption is not apparent.
I did talk to TOYOTA CANADA. Toyota asked me to send my viehicle to delership to get test. After communicating with dealership, they said I need to get the engine oil changed at their ficilate at first. And they will monitor the engine oil consumption. I was confuded for if I need to make a trip to approve my evidence. I gave up. I prepare some engine oil on my suv for a long trip.
If I can get a conveninence and economic way to fix it, I defenetly go with it. I hope I can still drive this viehcle at least 5 more years.

I have an 02 higlander, 151,000 miles. it started using oil last fall. the oil light has never come on and i only found out when getting ready to go on a road trip, i checked the oil and there was none on the dip stick. I finally took it to the dealership who changed the pcv? valve, did a consumption test after 500 miles, and all checked out fine. I thought we solved it..
I just went on a road trip this past weekend and checked the oil before i left. It was good. I drove to billings montana from denver and parked it. when i went to leave and started the car, the engine banged around and a puff of black smoke came out. i turned it off right away! that had never happened before..checked and again, no oil on the dip stick. put about 2 1/2 quarts in, and all was well. I put the other half in at wheatland, and now the oil level still looks good but i called the dealership and told them the pcv valve wasn't the answer obviously. I took it in and after looking at it, they told me they'd have to remove the top of the engine (or something like that) to check on a sludge issue that had been happening with these cars awhile back, and that would cost ME $450 alone. but... that if i kept up with the oil, the car will probably be fine for a long time.
Other than the indications on the dip stick, there are no other "symptoms". Never any leaks on the ground, never any smoke coming out except what happened the other evening...they are not offering to pay for it AND i don't recall ever getting a letter re: a sludge issue. I am now and always have been on top of all the maintenance required....

I never did find out what Edelbrock air filter to use but it doesn't matter now because we are to the point of either replacing the vehicle or repairing the oil problem. I think we'll repair the engine, it's a better option for us than buying a newer vehicle right now. We did start using a synthetic blend oil (Trop Artic) which works a lot better than straight motor oil and very reasonably priced compared to other synthetic blends. We can definitely relate to your frustration of the oil problem and, unfortunately, AFTER buying our Highlander and finding out about the oil problem with it, we then did some homework on it and found out this is a common problem with the 2001, 2002 and then got better starting with the 2003 models. The funny thing is, after doing a lot of vehicle shopping the last few weeks I still like our '01 Highlander the best, still looks very good inside and outside for it's age and you can't beat the price tag even with the repair of the oil problem
#38 of 52 short trips or a lot of idling

I just picked up a 2001 highlander v6 70k miles, 3rd owner last year in summer of 2011. Now in 2012 around June, I started noticing the oil sludge problem. So I took it to a shop and the auto guy said I had carbon build-up because I take short trips or a lot of idling too much (what a liar never heard that one b4) cause of only 5k miles into it for a year and it needed motorvac, etc ..cost $450 for treatment. A month goes by and still the same thing oil consumption. 4 more months go by with the sludge and one cylinder misfires. So now my car is in a shop and an auto guy tears the engine block down to tell me that a piston valve broke, oil ring broke, needs new piston ring all due to oil sludge . I mean come on Im at only 80k. But anyways I want to know if I can still get the toyota sludge settlement even if the car is a 2001 and now its 2012 and the settlement only covers up to 8 years? Cause all these repairs is causing me a lot of money. http://www.oilgelsettlement.com/
