More engine assembly progress...

It is now time to start putting everything back together. The second photograph shows us measuring the deck height in order to calculate your compression ratio. We are going with a custom (0.051") Cometic head gasket that will result in a compression ratio of 9.07:1.

The following photographs show Harold completing the align hone, machining out the old sleeves, then honing the new cylinders and decking the block. We plan on reassembling your engine over the next few days.

Let me know if you have any questions!

Align honing in progress
Removing the old sleeves
 The water jackets you see in the cylinders
lurk behind sleeves and are always gummed
up - which is why we always re-sleeve the
block in CJ engine rebuilds
Cleaning the block
Honing the new cylinders
Block is decked with timing 
chain cover in place
 Balancing the connecting rods

As you can see, we have now turned our attention to your engine block. The following photographs show the main caps being machined down as part of the align boring process. The purpose of this is to ensure proper and consistent load on the bearing and proper main bearing clearances.

The cap you see on the fixture with the dial indicator shows Harold measuring how much he needs to machine off each cap in order for them all to be precisely the same. We will be align boring your block later today, so more pictures to follow!


Putting the finishing touches to your cylinder head, including a couple of coats of Pumpkin Gold paint! Notice the re-shaped chamber in the first photograph.


The cylinder head machine work is now just about complete and the new valve seats installed into the re-shaped domes. The photographs show the process of machining away the old seats followed by welding up the seat bores, then cutting back the weld and re-shaping the domes - then finally the installation of the valve seats.

As you know, the transport company kindly dropped the engine crate on its head, although thankfully the only damage was a couple of bent cam studs (see first photograph below).
I must say, I have never seen such badly damaged pistons in an engine that was still running! I can only assume that they were set up with inadequate skirt clearance. Still, as we re-sleeve the engine anyway in the course of a CJ engine rebuild, it really isn't a big deal. I don't anticipate any problem saving the head, although obviously somebody has made some strange cuts around the valve seats on the exhaust side....

I have provided a replacement crankshaft and I am pleased to report that we already have the machine work is underway. Watch this space, Tom!
