Hey guys, have a bit of a problem with my '04 3.8L engine. Had a gentle tick before an oil change which grew markedly worse after an engine flush. I ran some seafoam and marvel mystery oil through the engine, changed oil again, no dice. Pulled the lifters out and dismantled several. Found a tremendous amount of metal in the driver side lifters, looked like glitter. Replaced lifters, ticking still going strong. Starts out quiet when the engine is cold but grows steadily worse as it warms up. Added a can of BG motor oil additive (sold to me be a local mechanic... never heard of this crap, but he was insistent that it would help.) At this point, I'm just worried that its gonna lead to engine failure. Anyone have any ideas? Need some guidance. Going kinda nuts.
