Oil change is definitely easier than pulling intake to inspect lifters and cam.Dont think it is a wiped lobe as it goes away after a few minutes.Did start a few hundred miles after draining brad penn breakin oil. Thanks for the tips i'll try it tomorrow if I can get the kids to bed early enough, Heck I'll have my 6 year old do the oil change for me, he loves wrenchin on the dart and feelin chirpin of the gears from the back seat. How about the high zinc oil additive I've read about here?
