Monday Boy: there's a knocking when I driva Me: knocking or ticking? Boy: Ticking, kinda metallic Me: OK, need to adjust the valves. Boy: it's also backfiring Me: sounds like an exhaust leak. Let's do it Saturday morning. Wednesday night, I had a chance to take a look. #1 and #3 exhaust pipes loose, and #4 exhaust valve adjuster was making a break for it. @caden_cec #aircooled #vwsforlife #aircooledlifestyle #wrenchtime #maintenance #valveadjustment #whatswrongwiththispicture (at Lake Forest, California)
