The revival of 650143R, 1970 with TS.

I may be getting myself into trouble again.
Seems I may have found a source for aluminum Renault flywheels.
Sent an inquiry today.

That's a steel flywheel.  Bonus that it takes a standard clutch.

[Richard48Y]

About 7.5 Lb.
I realized it is steel after I posted.
Only feature I do not really like is that starter ring gear appears to be integral.

[Richard48Y]

The light steel Renault flywheels are available.
"£387 including shipping to the USA".
I have to wait but am happy to have found them.

[jbcollier]

Good find indeed.  The other steel flywheel I know of only takes a special 180mm clutch.  This is better for a road car.

Got my head back from HBR today.
Looks very nice, lightly ported and minimally milled.
Too dark to get decent pics so will try again in the morning.

But here is UPS contribution to my heartburn!
Yes, I will be complaining to them.

Ouch!! 

[Richard48Y]

Good head porting pics are still being difficult with this digital camera.
For real photography I would have to revive the film camera.

[Richard48Y]

Found some "Before" pics.

[Richard48Y]

Hmm, several senders to identify and replace as needed.
One appears to be a thermal vacuum switch, doubt I really need it to function.
Two look like temp senders, oil and water?
But both are in the head.

[jbcollier]

The one with the single (broken ) connector is the original temp gauge sensor (Renault).  The other two are sensors for the fuel injection system: one to control the cold start injector, the other a temp sensor.

[Richard48Y]

Thanks, so I can just use them as plugs since I expect that finding actual plugs to take their place would be about impossible in the US.
Single terminal temp sensor is the same as used for my temp gauge?

[jbcollier]

The broken sensor would match the Renault gauge.  It probably won’t match your gauge.

[Richard48Y]

Since none of these plugs appear to be pipe thread I think I will try to remove the plastic portions and fill the remainder with epoxy.
I think that will look better than obviously broken senders.

[Richard48Y]

I was able to clean up three of the four useless senders on the lathe by turning off what is not needed.
I will fill the body of the other with epoxy.

Getting close enough to having a running engine that today I pulled my junk? R16 transmission off the shelf.
I will remove the bell housing and adapt it to a flat plate for use on my engine test stand.
Penetrating oil applied for what good it may do.

I am ready to begin putting the oil galley plugs and some senders back in the block.
When I dismantled it I was shocked at how loose some of them were.
Recommended sealant aside from the copper crush washers?
I have been leaning toward blue Loctite.
