I did 12 marks on the oil outlet like a clock...


Using a .6mm drill bit...


I drilled a hole around 7:30 - 8 o'clock (about 15mm from the top) and...


At 2 o'clock to squirt oil on the primary chain at the leading edge of the limiter and the tensioneer (Source: Mike O).


The new and improved drive shaft for the oil pump.


The cover is on.


The water impeller is in...


The cover is on.


This side is about done.


Installed the oil seal.


I've installed the accessory shaft flange with the slot on the top and made a mark on the housing. This will give me a quick indication of the TDC on #1 at firing when the engine is closed up.

Timing (End).

The A head is timed. I have marked the cam shafts with paint since I will remove them to lubricate everything.


I've cut a piece of sheet metal to install the chain. I use a magnet to catch it below the sprocket.



One cam shaft was really stuck.


Timing the B head.


marked the cam shaft with blue paint to reinstall them easily.


I used Lubriplate on the side of the valve caps and Clevite on the top.



I've measured the maximum torque to make sure everything turns freely in there (51 ft/lbs).


Checked every cylinders with the distributor on.


Covers are temporally on to protect from dust.

Valve shims and timing...

I use a dial caliper for precision measuring and I double check with a digital one.


Starting to do the valve timing


Richard, "l'heureux proprietaire" (the happy owner). He did a lot of work cleaning, painting parts and helping me with some tasks.

Timing chains and A head

Installed new primary timing chain.

Setting the space between the limiter and the chain.


Ready for the heads.



I use a long narrow plate to slide the chain over the sprocket, then I retrieve the end of the chain with a magnet.


Measuring the valve/cam shaft clearance. I enter the measurement in an XL spreadsheet I've designed to find out which shims I can reuse and the ones I have to buy.

Crankshaft and pistons...

Checking fro the lateral play of the crank.

New bearings but with some oxidation on surface. I've used a white Gex pad, very lightly, to remove the top oxidation.


The bottom shell is ready to be installed.

Last picture before closing the bottom.

Valves, oil pump and rings

Received the new exhaust valves.


I wish the engine would stay this clean...


The A head received a new intake valve also.


Leak test.


The engine is back and ready to be put back together.


A lot of crap in the oil pump!



Clean and ready to be put back together.



The B head had a tight valve guide. I've honed it gently with very fine grid until the valve was sliding correctly.

Leak test on the B head.


Started to do the rings. Long and tedious job.

One done, five to go...

The engine is apart...

It took 24 hrs, heat and WD40 to get the water pump apart.

The chain needs to be replaced.



The main bearing are not bad.


The loose rod cap touched the casing.


Let's hope that the damage is not too deep.


The cylinders are good shape.

The rest of the crank is good. Two rods are twisted and need to be replaced.
