My 2006 9-7x has been down for 5 months as result of cylinder 1 AFM lifter collapsing. I tried flushing the engine and also squirting Berryman carb cleaner under the push rod, however the lifter is dead. So, i am serious considering law the job-related myself come replace all of the AFM lifters. Has actually anyone ~ above the forum excellent this before or execute does anyone have links, videos, etc. That shows details tearing under a 5.3 engine while that is in the truck? I consider myself an average shade tree mechanic. I very own 6 vehicles and also have performed all my own auto job-related for the critical 25 years. I"ve rebuilt a couple of engines and also automatic transmissions.

are you going to store AFM? thought about ditching it? ns don"t know anything about AFM. Execute you think friend really have to replace the sink cover? deserve to you maybe just flush the passages?the gasket collection should include valve seals.ARP head bolts room a small pricier, however you don"t need to torque come yield. So you don"t require the edge wrench. No a huge deal once you"ve gained it on an engine stand however when the in the engine bay acquiring x levels of rotation may be an issuepull the radiator, condenser, and ac hoses and also there is plenty of room. Also, check out camaro, g8, fullsize truck and so on sites for deals, many of people who delete AFM have parts to obtain rid of, for example that sink cover is easily accessible on a g8 site to be on there for a while so you can probably lowball them
