Rattling. Not likr a lifter...more like a rough noisey engine
Expert:  FIXITMAN replied 8 months ago.

Thank you. From what you are explaining it sounds like you have a failing timing chain. This is very common on this engine. The timing chain either wears and becomes stretched, or the tensioner fails. This causes the compression to be off and will cause the engine to run like this. In some cases it can be caused by engine misfires from worn out spark plugs so I would check and replace those first, but you should expect that it may be a much more extensive repair. Please let me know if you need more help.
