Yes, I checked the oil level and the oil is very clean. I'm going to run it, with a wait and see. Can any one suggest a good lifter additive? Thanks

Thanks for replying. I have never changed it myself, as it is too hard for me to get to the oil filter. I have used the Atlanta Lexus dealer, then the local Toyota dealer and now the local GoodYear dealer. They are using NAPA Gold 10W30 motor oil. And they use a NAPA oil filter number 21348.

Right after having my oil and oil filter changed, the lifter/s became noisy upon startup. The noise goes away after about 3 – 4 minutes. Since the problem showed up right after an oil & filter change, could the oil filter have a defective oil valve which is allowing the oil to drain back into the oil pan and is the cause of the problem? Background: I bought my 1999 RX300 new and it has 57,000 miles on it. Yes, 57,000 miles. I drive it every two or three days and am now averaging 3,000 annually. I have always changed the oil every 2,000 to 3,000 miles due to the known sludge problem with this engine. In other words, I keep the engine oil very clean. Any insight on my problem? Thanks
