Question about 2000 Volvo S80
The engine knocks on start up and continues until turned off. Digital reader says cylinder 1 is misfiring. Been told by a few people that the lifter might be collapsed or stuck, could this be the problem, and is there a way to fix it with out having to rip it all apart to change the lifter?
Yes the lifter or one of the valves could be damaged. No the valve cover and maybe the cylinder head would need to be removed to repair depending on what the actual problem is.

SOURCE: Car is knocking
Sounds like a bad connecting rod bearing or a carbon knock, de-carbon the engine and retest for noise, if it is still there the engine will need to be torn down the crank refinished and new bearings installed.

The knocking noise of these engines is usually from vacuum pump. Just remove the 6 torx screws from vacuum pump cover with a hot engine and let the oil drain from it overnight. Be careful not to loose any part of vacuum pump - has 2 metal one way valves, one plastic valve and two rubber parts one big seal and a washer. Remember how it was installed and clean those parts with care before assembly. The hose on vacuum pump cover doesn't need to be removed - rub clean cover with cotton cloth. The tractor-like knocking sound was gone on my car!
