My 2006 9-7x has actually been down for 5 months as result of cylinder 1 AFM lifter collapsing. I tried flushing the engine and also squirting Berryman carbohydrate cleaner under the press rod, yet the lifter is dead. So, i am seriously considering law the job-related myself come replace every one of the AFM lifters. Has anyone on the forum excellent this prior to or do does anyone have actually links, videos, etc. That shows details tearing under a 5.3 engine while it is in the truck? I consider myself an average shade tree mechanic. I very own 6 vehicles and also have performed all my very own auto work for the last 25 years. I"ve rebuilt a pair of engines and automatic transmissions. So, I"m no an expert, but I haven"t run into any type of repair instance I couldn"t handle, knock wood.I"ve put together a "possible" parts list. I might not have to replace whatever below. For instance, the cam, pushrod and also rocker arm may be fine.

are you going to save AFM? taken into consideration ditching it? i don"t know anything about AFM. Carry out you think girlfriend really must replace the sink cover? deserve to you maybe just flush the passages?the gasket set should encompass valve seals.ARP head bolts room a tiny pricier, however you don"t have to torque to yield. So you don"t need the angle wrench. Not a big deal once you"ve gained it on an engine stand however when the in the engine bay gaining x degrees of rotation might be one issuepull the radiator, condenser, and also ac hoses and there is plenty of room. Also, examine out camaro, g8, fullsize truck and so on sites for deals, lot of of civilization who delete AFM have parts to obtain rid of, for example that sink cover is available on a g8 site been on there because that a while so you deserve to probably lowball them
