Remember the stuck Pontiac 400 I freed up last year? (https://gbodyforum.com/threads/doing-the-unstuck.69747/) I finally opened it up for a look-see. First off I was right about the valley pan leaking. It was horrible. But it didn't have to be so. The morons I am following decided not to replace it. Just schmear orange RTV all over it and call it done. YIKES!!! Had they used something decent like Marine Tex it might have worked. But no- just use whatever is the cheapest at Auto Zoned Out. Then when some gas or oil hit it it failed and let water fill the engine. But after I got the engine unstuck it shook and rattled for quite some time. The lifters banged like crazy until they loosened up and smoothed out. One kept clacking on and off even until now. Sometimes really badly. See the pic for the reason. Damn lucky the push rod held the lifter top piece from falling into the engine. I put it back together and it seems OK. Then I noticed the rocker nuts were some cheap-*ss Chinesium attempt at poly locks. (Just $9.99 on Flea Bay. Hurry! Almost sold out!!! ) When I put the rocker arm back on I no matter how tight I made the set screw I could still turn the nut easily with a 5/8" wrench. What junk. Maybe I can scrounge some real Pontiac jam nuts. It also looks like not one gasket was actually replaced. Just schmeared with the orange goo. Stay tuned for more surprises.
