Just because the marks line up doesn't mean the keyways havent sheared or bend from either phaser or crank bolt not being tightened properly.Pulled the heads today. Every valve, intake and exhaust on both heads have a mark on them from touching the pistons. I took heads to machine shop to be redone. He said if they touched they will probably be bent.
I turned the engine over until timing chain and gears were matched up again. They are still in time. Top gear at 12 o’clock with double mark in chain on both sides of phaser mark and lower gear with mark on chain on tooth with mark. I knew that’s what I would find.
so that means the only possible problem is either the phaser or VVT solenoid.
is there any relearn procedure for the pcm when the phaser is replaced?
I called summit because I bought everything from them except the VVT solenoid. That came from federated. They are telling me I need to call Melling since it’s their phaser and get an RMA to return parts to them. So tomorrow I’ll be on the phone with melling.
im interested in figuring out what went wrong so I dont have this issue again.
‘please give me any knowledge you may have. These heads will be expensive to repair and I don’t want to do them again.
