Okay....first off..I'm not a believer in snake oil...but read a lot online about how this stuff REALLY works on sticking lifters...(MMO)
So I poured some Marvel Mystery Oil directly down the pushrod valleys which of course go straight to the lifters/hydraulic lash adjusters .....let it soak on them (although only one was making noise) for a few hours while I went to job....came back..started it up....TICKING GONE! ...well at least for a couple minutes...and then slowly came back BUT NOT NEARLY AS BAD...VERY MUTED.
(Before ticking was immediate at startup and continuous.) So now I'm going to drain a quart of oil and dump the rest (majority) of the MMO into the oil.
Will post back results in day or two...sooner if more dramatic!
