Hi guys i think i have a stuck lifter on my 1990 F150 4x4 351W i though i was doing the right thin and when i changed the oil ther other day i ran a bottle of engine cleaner threw befor i dropped the oil now my motor sounds great when it is sitting iddle in the shed but once its under load it sounds like there like a truck with the exhuast brake on (very loud and pooping noise coming from the end of the exhaust pipe) my mate has said they it sounds like a stuck liffter has anyone got any advise on how to change thease out
Based on what you stated it sounds more like a stuck exhaust valve, one stuck part or all the way open, more then say a stuck lifter. Not to say a lifter couldn't be holding one open, just its no where near as likely a condition to happen.
Thanks i will try have a look and see if all the rockers and valves are moving the same thanks to everyone for your help i am a first time f truck owner and i am way out of my depth but im determined to work all the issues out my self
