Engine assembly

Did you replace the chain and gears or are they the old ones?

Hi,

That's good to hear. I'm glad you got it figured out. If possible, let me know how things progress for you.

Take care,

Joe

Good find.

We are always here if you have any further questions.

When you set the initial set up for the chain, it or they will go on the timing marks. After you rotate the motor, they will not line up at any other time.

Hi,

To the best of my knowledge, there was an issue with the 4.0L pre-2003 where oil would drain too fast and much from the cylinder heads. The parts in your hand were used to restrict how quickly they drained.

The threaded plug was used to stop oil flow in one of the oil galleries, and the thing that looks like a candle was used to restrict the drain in the cylinder head.

If you look below, that is the only thing we could find related to these parts. Also, note that they appear to come in all timing chain kits for the 4.0L, but they all don't require their use.

If nothing was found when you took things apart, chances are it isn't required on this vehicle.

Let me know if this helps.

Take care,

Joe

See attached pic.

Are you able to use a clean-out tap? If the threads are damaged, it will repair them. However, I don't know how bad they are. As far as the size, that is going to be based on the side you drill it to. What to do is this. Take the bolt with you and ask what size drill you should use to clean out the old threads so you can use a Helicoil. Also, when you install the Helicoil, use Loctite so it doesn't come loose. It would be a good idea to use it on the bolt as well.

Make sure to get a size that is closest to the original size.

Let me know if I can do anything to help.

Take care,

Hi,

I don't have actual pics of the bolts. However, there are 12 of them that hold the water pump on. I attached a pic below showing what I have. Also, if I recall, there will be a few longer than the others.

The timing chain cover bolts will be smaller in diameter and shorter in length.

I hope this helps.

Hi,

I found a pic on eBay showing the bolts for the timing cover. Take a look at the picture and let me know if that helps.

Joe

Hi,

They have to be installed before you install the camshafts. They are under it and can't be installed after the timing chain has been attached and set.

Let me know if I can help.
