Update! Fixed that problem! The lifters on 1,4,and 6 were sticking in the guide trays. Runs good now. I bought new felpro head gaskets. And bought the metal felpro intake gaskets. Runs good but after driving around for a hour or so I got a p219a code. I did smoke test on the intake. No leaks. I pulled fuel rail and checked fuel injectors. They are working great. Bought new o-rings and installed the injectors back in. Still getting p219a code. Help!

Oh yeah. Getting po300 code only.

It ran good before. Just had the lifter noise. It was only one lifter on #1 cylinder that failed. I've done mechanic work for 25 years until my health failed. But haven't worked on this particular problem. Have worked mostly on 60's-90's cars and trucks.

#7 is working

Have pulled valve covers since.It runs good for a second at start up then starts running bad. With valve covers off. #1, 4, and 6 rockers aren't moving. They move when I'm turning over by hand. It's a new vlom.?????

Had dreaded lifter tick. Replaced all lifters. New head gaskets, intake gaskets , coils, wires, plugs. Adjusted rockers to 22 ft. Lbs. By the manual. Torqued heads by the book. Using torque angle gauge. Got it together. Runs rough. Any ideas?
