Has anyone mentioned the anti-drain back valve above the rear main in the block? If this is lost or not replaced during removal of the crank, most typically during a total overhaul, the oil in the galleys will return to the crankcase more rapidly when not running. Here is a reply to a similar question from a few years back from George Riehl regarding this: What you need is a "oil gallery block off valve". This valve directs ALL oil to the filter on the 354 and 392 Hemi. It can be used with the stock oil filter and spin on filter. It is a perfect replacement with no machining required. Have used this valve since the early '60s on my race hemis. Can be used in "normal" hemis also, but NOT with a high pressure oil pump. You will find the your oil pressure will be slightly higher than normal when using this valve, but not excessively. Do not use more than a rated 30w oil. This valve also helps to prevent "drain back" when the engine is not running. It can be purchased from PAW, 21001 Nordhoff, Chatsworth, CA. 91311, phone 818-678-3000, FAX..818-678-3001 Part number HEMI-5340 George Riehl Wayne [Non-text portions of this message have been removed] ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/Yahoo!
