Alright, I've had some bad lifter tap. I've been running 10w-40 amsoil in my car. My engine is an m52 with ~170k miles now. Whenever I run my car hard I'll get lifter tap, and it's just been getting worse. From a few times running it hard, to just driving it on the highway at around 3k rpms. I decided to try a couple of things and try to solve this lifter tap situation without having to replace the lifters. I added an extra quart of oil to see if maybe I was just getting air bubbles in my lifters. It didn't solve the problem, so I put a bit of ATF in my engine, to help clean up some of that gunk. It helped a bit, but the lifter tap would still come back. People were telling me that I should run a thicker weight engine oil (15w-50). I just don't like the idea knowing that I would pretty much be running the same weight engine oil as desiel cars...
So today I ran an engine flush. I put Amsoil Engine Flush in my car. The directions say to drain some out, and fill whatever was drained out back with how much of the engine flush fluid you need. I didn't drain any out. The directions then state to run the car at high idle for about 20-30mins. I ran the car at 1500rpms for 20mins. Pulled the car back into the garage, jacked it up and drained my engine oil. The oil was VERY thin coming out since the flushing fluid was in it and because the engine oil was hot. I completely drained the oil, replaced the filter, and added 9 quarts of Amsoil 10w-40. Checked the dip stick, and went out for a drive.
I drove the car hard. Trying to drive it as hard as I could pretty much with the space that I had to work with. No lifter tick. :) yet. I'm going to be gone for the weekend so when I get back I will drive the car again and keep updating this post until I finally find a fix for my lifter tick without having to replace the lifters.
Thanks for letting me waste your time :)
