First engine build.

Now for the timing chain oiling system.

I have seen three different configurations from the factory from 67 to the mid 70's.

First, I would recommend cleaning up your parts a little better with a wire wheel on a drill and some brake parts cleaner. I like brake parts cleaner (the red chlorinated can - not the green non-chlorinated) as the brake parts cleaner dries faster and removes the color. Also Barryman's B-12 cleaner works well on some real black carbon stains like you typically see in the carburetor. I would recommend having a can of each handy. You can get both cleaners at Auto Zone.

Ok, now you have to put the thrust plate on. You will need the proper bolts. Here are what they look like:

Here's a picture of the two different styles of bolt for the thrust plate:

Here is a close up of the "unique one" with a hole in the center of it:

Here is a picture of the front face of the block:

Here's the same picture showing the location that the bolt with the hole drilled in the center (this allows the oil to drip from the valley of the block). I've seen some engines without this bolt and the hole just left open. This hole needs to be open, or with a bolt with the hole drilled through it, as it is the source for the oil for the timing chain:

Here is a picture with the three holes for the other bolt circled. The two lower holes are for the "oiling tab", the thin metal bracket from your picture with the point. I've seen some engines with out this, but I like to use it as it directs the oil to drip down directly on the timing chain crank gear. I feel that this is the best way to make sure that it is lubricated. To mount the "oiling tab", you put the non hole bolt in the hole in the tab and that goes to the bottom passenger hole that is circled above in red. Then the anti rotataion tab goes into the bottom driver's side hole for the camshaft thrust plate. I would recommend using the upper bolt with the hole in it if you use the tab, as I would not want to use only two bolts to hold the trust plate in. If you don't use the bolt with the hole, I would recommend opening up the hole where the locator tab goes into and modifying the anti rotation tab so you can fit a bolt through the hole and still have the anti rotation feature (hopefully you can follow what I just meant here - if not ask questions).

Stay tuned for part 2. I need some time to process the pictures. Tune back in 30 minutes....
