Oil Leak At Valve Cover

I still use them sometimes... I've got some here waiting to go on my vehicles!
PH16, PH6022 and PH8A!!! They were on sale and they have never failed me!!! I've seen the tests and I've heard that they suck and I still use them. Why? They were on sale and they have never failed me, lol,....

I change my oil every 3000-4500 miles and use synthetic in my daily drivers and conventional in my 69 Dodge and 07 Softail with ZDDP additive (STP oil treatment/store brand ok). Everyone with a flat tappet cam should be using the oil additive, IMO. I believe we would see less cam problems if we all used it. The bike needs it because it is air cooled and that means it's hot blooded.:snakeman:
