Getting code poo17, new...

Getting code poo17, new camshaft actuator solenoid, camshaft sensor, crankshaft sensor, plugs and #6 cylinder coil. engine is now missing on #5 and #6 cylinder. when the problems started it started to tick and than it started to knock bad, sounded like a piston was going to go through the block.

Mechanic's Assistant: Cars do make very odd noises -- They help the mechanics figure out what's wrong. They are terrific with my old Grand Cherokee. Are you hoping to fix this yourself?

Yes

Mechanic's Assistant: Great! What have you tried so far?

I believe I just told you in the first text

Hello, first have you checked the oil and made sure it is topped up and that the filter is in good shape? Secondly, assuming that the oil is ok, sounds like there is an issue with either the timing chains being stretched, or maybe just worn guides. Either way you'll have to tear down the engine somewhat and inspect. How many miles are on the vehicle?

If I installed a new camshaft actuator do I have to prime it where the check valve is?
GMC Mechanic: Andrew Martin,
 replied 2 years ago

No just start the vehicle up and it will fill with oil immediately. No priming required.

Has new oil, still knocking. Ready to shoot the truck.

Oil light on? And are you using a factory filter? Also, make sure the oil is at the proper level.
