Hello,
every time I had to adjust the advance I took the wrong reference because the pointer was missing. So I put piston 1 at top dead center and built my pointer (which was missing) starting from the photo of what the original should look like. This is the result.
I used a 20 mm x 2 thk aluminum plate, bended and drilled.

Hello,
I have removed the water pump and found both passage through the timing chain cover completely closed.
At the moment I have removed all the dirty and washing the engine with clean water.

I think that the water pump not properly work. Why the lower hose of the radiator has not so hot as the upper one? The hose from the termostat housing was not possible to tuch with the hand, the lower yes. Is this normal? I think that if the radiator cools the water it is still at a temperature that the hand cannot tuch. The limit for the hand is 60 °celsius.

edit:
this evening i have removed the belts and loose the pump impeller that I have rotated by the fan. Moving with the hand the fan the pump rotate very free. I have in the garage a new water pump as spare and it is not so free in the rotation. Coud be an impeller problem.

Today I tried to remove the air from the circuit using the bottle. Everything worked well, the engine went up in temperature and the thermostat started to open before the instrument indicator came to mid-reading. The water began to rise in the bottle making bubbles, I kept the engine at idle and the temperature went up, the instrument indicator was on the letter P of the letter "Temp" of the instrument, a few moments came down then went up again. I run the engine faster and the water went a lot in the bottle. It didn't go up and down as seen in the videos. I held the engine 10/15 minutes running. Then I turned off the engine and the water went down into the radiator. I removed the excess water and after about half an hour of waiting I closed the radiator and left for a test. The temperature still went up a lot and the water came out of the tube under the radiator cap. I suspected during th operation the water went back into the engine from the top where the thermostat is. The radiator tube in the lower part of the radiator was not as hot as the one above. Could it be a water pump problem? Thank you for any suggestions.

New oil, new filter.
Wait the warm up of the engine and check the pressure.

Is the viscosity of the oil correct?
What ambient temperature was there when at idle the pressure reached 4 Barg ?.
If something was in the circuit it will now be in the filter. First of all I would change the oil filter.

Hello,
I had some trouble bleeding the air from the cooling system by running the engine only because if I leave the open radiator cap, the cooling water comes out from the top.
I would like to connect an atmospheric tank to the radiator and try to purge the air from the cooling system by running the engine until the thermostat opens. I saw a video on the web and my idea is to use the tank shown in the picture.
Has anyone used this method before? Thanks for your suggestions.
Marco

Here the pictures, about the part inside the green cloud, where the grease has to be filled? completly also where the pivot working? My opinion is that inside the bronze bushing is not necessary to fill completly but it is enough only to wet with grease. In facct during the dismantling the part was not filled of grease.
Thank you for your opinion, Marco.

Hello,
I found oil leakage from the power steering control valve so after a deep study how to rebuild it the works starting.
At the moment I have dismantled the control valve, today the spare pars arrived from USA so I can planing the work.
Looking at some tutorial in the web I saw a man filling the bushing with grease and others not. I'm not sure to fill with grease is correct, I agree to wet the inside parts but i belive the grease should be in the external of the bushing where is necessary for the little stroke. Oil side no problem, appreciate your suggestion.
Regards, Marco.

Hello,
the work started but I was unable to check the interference between the rocker arm and stud because the hydraulic lifter, not being preloaded by the oil pressure, absorbs the thrust of the spring and the rocker arm does not make the whole stroke.
So to simulate the preloaded lifter I thought to disassemble one that I have in stock and place a thickness instead of the spring to make it rigid. This could allow me to complete the verification. I'll let you know

Ciao Alessandro,

If I were you I would start again from the beginning. Put rod, jets and spring (color) like 1405 is from origin. Then check the installation, I used timing port and my 1406 ran well. If you have automatic chocke, where do you get the positive from? not from the positive of the coil is better. Position the acceleration pump lever as from origin. How did you connect the PCV valve to the carburetor? I remember the rear port on the carburetor must be connected to the pcv on the valve cover. Check that the PCV is working properly. Check the carburetor gasket with intake is ok, if you have opened the carburettor check the gaskets again, you have opened it to change the jets. (It is to be done with caution so as not to break the gasket. When you close the carburetor there is no need to tighten the screws a lot, go to the bottom and give it a light tightening). Close the two screws of the air and April by two turns. Start the engine and bring it to temperature, turn the idle screw to raise the idle to 1500 rpm, close the passenger's air screw slowly until the engine starts to turn unbalanced, reopen it until it returns balanced and do the same with the other air screw, then lower the idle with the idle screw.
Also consider that we are in winter and the air has an important game in the carburetion.

 Then adjust the carburetion, it is a job to do and redo because it is influenced by the advance however if you have already made a basic advance do not touch it for the moment

MAKE SURE you use the correct intake manifold gasket for you engine/intake. 289 and 5.0 heads are different (I believe) as far as gaskets go.
I like to use long bolts with heads ground off (4)to help align intake when setting on engine. Don't use the rear gasket (along valley cover) use RTV instead . Hard to get a good seal in that area.
Let us know how it goes!!

Not just the 5.0.  The heads changed sometime in the mid '70s.  Most gaskets I find do not work with the old style heads.  The coolant passage holes are completely wrong for the early engines.  I used a set of Mahle gaskets when installing my Edlebrock intake that worked very well and had the right size openings.  MS15172 from rockauto.com. 

Thank you TKO, i have purchased FelPro MS 901031, this is not the first time I use this gasket and never had problems.

Hello,
ok, I think the time to work on the engine is arriving.
I will proceed as follow, first I will remove the intake manifold for two reasons: one because for a lot of time the car was running very hot, I have alreadt replaced the radiator but I think the reason is also the little radiator under the dash, and there are signs of steam from intake cooling circuit, but the principal is that I can observe the famous lifter, push rod and rocker arm of intake cil. nr.7 during all the movement, trying to understand and found some issues.
Then I will replace the studs rocker arms and I will proceed to reinstall a new rocker arms, before of this I will put prussian blue onto the stud and carefully re assemble everything. If interference accour I will found the rocker arm contaminated with the prussian blue.
An other way to check interference is to keep an old rocker arm and enlarge the slot and check if there are difference in the complete lifter height of the rocker. This is hard to understand if the difference is minimum. I know that even a 1/10 mm (0.004") is enought to cause a broken when as an hammer the rocker received the blow.
Than I would remove the spring so I can verify if the valve properly work.
So it is all a research phase but it is important to understand ...at the third time which has broken.
Marco.

Thank you, so it is only the check valve that allows the oil to pass.
Ok, I found oil onto the rocker, so the system properly work.

right, new lifters were replaced when the cam was installed. But due I dont know how the oil pressure reach inside the lifter, I mean timing sequence, it must be always in pressure by the oil, or during the cam is rotating the lifter itself close the oil pressure during the stroke when necessary? I made a research in the web but not found anything, only a sectional view of the lifter with parts description but not a description of how it work in the general, not only about it  functionality.

I want to belive the stock rockers work without issues with compcam XE-256H.
Future check will be lifter condition and preload, pushrod (not bend) and rocker/stud interference.

...and I have also this question: are the stock lifter suitable for this camshaft?

This would not be a problem because 289 my66 heads are self align rockers (no rail), the point where the pushrod pass through the head is slot type not an hole and guideplates do not exist (this is stock configuration).
I thought to modify the pivot, cut the bottom, drill to proper diameter.
Making this the pivot will work like the semispherical piece. but I prefer not to try with experimentation, I have not a spare engine and I would like to save the original components.

I understand now that this type is not adjustable. The pivot is tightened to the threaded hole (5/16") on the boss on the head, the pushrod have it's properly lenght so all the geometry is correct once pivot is tightened.
