Replying to: wlblack (Feb 02, 2009 4:51 pm) after I changed the oil last week   That's a clue. Can you tell whether the amount of dripping is increasing, decreasing or remaining the same from day to day?   tidester, host SUVs and Smart Shopper Replies to this message: wlblack (Feb 03, 2009 4:24 am) tidester (Feb 03, 2009 8:34 am) wwest (Feb 04, 2009 9:15 am) and 2 more...

Replying to: tidester (Feb 02, 2009 10:22 pm) I've been watching the past 3-4 days and the amount "appears" to have decreased. It's gone from a small pool, 3-4" in diameter to about the size of a half-dollar and then last night there was maybe a quarter or nickel size pool. Last night I actually put an empty CoolWhip bowl under the area that's leaking and there's hardly anything in there at all.   We've owned the vehicle for about a year and have probably done 3-4 oil changes in that amount of time, every 3,000 miles or so, and it doesn't use any oil between changes. I always buy the big 5-quart jugs of Pennzoil full-synthetic and put in the whole thing along with changing the filter so maybe the "jug" had more than 5 quarts in it for some reason. The dipstick shows just a hair above the 2nd line which indicates a little more than full.   Is there an overflow type of tube like there are on some transmissions where the excess fluid drains out until the proper level is reached? Should I drain the oil and change the filter again or just keep an eye it for another week or so?   Thanks for your help.

Replying to: wlblack (Feb 03, 2009 4:24 am) I would just keep an eye on it but it would be nice if someone having hands on experience with the Highlander would jump in here.   tidester, host SUVs and Smart Shopper Replies to this message: wwest (Feb 04, 2009 9:15 am) tidester (Feb 04, 2009 12:35 pm) wlblack (Feb 05, 2009 3:18 pm)

Replying to: tidester (Feb 03, 2009 8:34 am) I don't have a HL but an '01 AWD RX300 which I strongly suspect has the same engine and configuration.   When I change the oil and filter I always run the engine up to operational temperature first to make the oil more free flowing and hopefully catch more of the particulates still in suspension.   I always use a funnel during refilling and am careful not to fill so fast that the oil overflows the valve cover intake opening. After I put 4 qts in I start the engine and let it run for a few minutes then wait (take this time for clean-up) for the oil to drain back down and check the level and then add the last quart and a tad. 5.3 qts, right..??
