So my car has started having a lifter tick about 2 months ago. At first it got so bad I couldn't drive the car without the lifters tapping. I peered into the crank case while the car was running and could see there were pressure issues (you can tell by the color of the oil and the slow movement). I changed the oil that day and took it for a highway run. Since then the tapping has quieted to only a few select times. The times it taps are : Rarely on startup. (Maybe 1/5 starts will have lifter tick which goes away as the car heats up). Otherwise as the car heats the tick stops. The only other time I get a tick is after driving for a long time. It's usually around 60-80 miles. The speed im driving makes no difference in when the car starts ticking (40 mph, idling, or 80. If its a long trip chances are itll tick regardless.). (If it is ticking the noise and rate will increase with the acceleration until the car shifts to a higher gear.) Otherwise short distance trips are completely quiet. Anything short of 60 miles or so is completely quiet, no hesitation or tapping, the car has amazing acceleration and no lash or noise. I'm lost! Help!
