Answer 1

This is likely the actual timing chain itself, but let me ask, how is it running? Does it run smooth or is it very rough?

Answer 2

Ok First thing you need to do is check the oil level. If it's low, that can cause knocking and will also cause the codes you are seeing. IF the oil level is fine, then you need to check the compression to see if the timing chain has jumped time.

Answer 3

You need a compression gauge and you remove all the spark plugs and test one cylinder at a time.

Answer 4

This really sounds like the timing chain is the problem I am sorry to say.

Answer 5

I checked, I didn't see any recalls for it.

Answer 6

I would not run it and if you have to have a shop look at it to at least confirm, but again, you need to start by checking the engine oil level.

Answer 7

If it's out of time the pistons could hit the valves, if the timing is off there won't be any spark on one of the banks.

Answer 8

if the timing is off there won't be any spark on one of the banks. In this case it's the rear bank, sometimes it's the front bank

Answer 9

check what with the car on? Compression? Here is a video [https://www.youtube.com/watch?v=X\_tbksFYhl4](https://www.youtube.com/watch?v=X_tbksFYhl4)

Answer 10

You check that with the engine off, pull the dipstick, wipe it off, then put it back in and check it.

Answer 11

yep, it will also cause the knocking sound

Answer 12

I would fill it with oil, but only if it will start on the front 3 cylinders, if it won't then the damage is done already. I have to sign out for the night. Please post here if you have any other questions and I will answer as soon as I am back on tomorrow

Answer 13

I would put some oil in it then and see if it helps. It sounds like the timing chain has jumped. If it has then that will have to be taken care of.

Answer 14

I see, well I think it's time to pull the timing chain cover and inspect it because unless you severely overfilled it with oil, that's going to prevent it from cranking.

Answer 15

Well, if it's not reading anything on the stick it's going to need more than a quart, but at this point it's time to get the cover off of it. Either tow it to a shop for inspection or remove the cover yourself.

Answer 16

Well, its' going to have issues on only 3 cylinders.

Answer 17

Check the timing chain, it's not going to start at this point you are likely just doing more damage.

Answer 18

You're welcome.

Answer 19

I think either that or check for a used engine to install.

Answer 20

Ok, well good luck to you.
