Getting X3 from the father-in-law. Has the standard ticking from a lifter or more than one. Couple questions. Some of people said that not driving a BMW, letting it sit, will eventually either foul a lifter or need to be driven hard to settle them down. Also, there is a "bleeding" procedure to remove "air" in the system. Never heard of that and will try that too. Also, some of mentioned they have used a couple types of additives during oil changes that has helped. The TSB for cars under warranty even swapped the cylinder head to fix the issue. If I can't fix it with bleeding or additives I might just swap the lifters. eBay/Amazon has sets for $125 or something. One additive they mentioned in BMW forums... https://www.amazon.com/Liqui-Moly-H...t=&hvlocphy=9021427&hvtargid=pla-569142978691 Saw this too... https://shop.advanceautoparts.com/p/liqui-moly-longtime-motor-oil-5w30-5l-2039/11566220-p Anyway, wanted to know if anyone dealt with BMW X3 or other models with the 3.0L "ticker" engine.
