Oil line plug/ low oil pressure on cold starts
Got some better snap ring pliers and took that extra lifter I had already replaced apart. Definitely had some dirt in it - no chunks, though. I think I'm going to take them all apart and clean them. I assume that dirt gets in between the bore and the inner piston and that gets them stuck?! I hope it's the last time the intake came off...
I've been looking for an oil with at least 800 ppm of ZDDP. It appears it's not listed as ZDDP, but rather as Zinc and Phosphorus separately. One oil I can get locally for about 37 bucks is the Valvoline Advanced Full Synthetic 5W-30. It's got 830 ppm Zinc and 730 ppm Phosphorus. By the way, the Brad Penn oil has been renamed PennGrade1, but it's not available nearby and also quite pricey.
