Filling cooling water ??

[plym_46]

Ah you should have had them take off some more and upped your compression ratio a bit.  More squeeze = more power!!

Any how glad its back together, enjoy.

Just as an after thought with the top of the radiator higher than the highest cooling passage in the engine, it is very unusual for these systems to get an air bubble that blocks flow.  It is more prone to happen in new cars where the radiator is typically mounted level with or below the top of the engine. 

One good thing to remember is to never add cool water to a hot system. Let everything cool down before adding more coolant and or water.

Go,

Good to hear that the Plymouth is back under motion again, too bad about the rain today, hopefully the sun will come out and you can enjoy the convertible soon

They had to machine off .008 inch (0.2 mm) of the warped head.
No chance to keep the gasket tight!
Since Friday, is running great agin!
Thanks for Your hints and fpor Carla?s e-mail!

I believe had a heat problem while filling water.The gauge went rightest. I have a second electronic meter, but the feeler attached near the Thermostat, so: Air trapped, no water, no block temp....

and yes, Elmo,  I had my mechanic take the head to the machine shop, check the warpage and to re- level it. Don?t know the result yet.
Thanks both for the valuable hints!

Greetings! Go

Did you have a problem with overheating???  Or did you have a leak while driving?  It is common for head gaskets to fail between paired cyliders as ther is not a lot of material between cylinder pairs.  Usually it is a dry failure, no oil or coolant involved as there are no fluid passages in that area.  The symptom is a loss of compression on one or both cylinders and a missfire on one or both of the effected cylinders.

Over heating can cause warpage of the head, which can then lead to a the gasket failure.  Some time the gasket just fails.

As noted when you pull the head, have it checked to be sure it is square and true, when reassembling the gasket should be installed dry, or use a bit of wheelbearing grease to help it stay located. Then assure that you follow the proper tightening sequence when torquing the head, and then make sure your retorque after a heat cycle.

In the pic you can see how thin the area is (at the 6 with the arrow) and also see how far away the cooling passage is.

Go ,
sorry but i dont think you can do a quick fix , on reading your post and the low miilage done between , i think you  probably have a warped head ,it would probably have warped if you kept driiving the car after the first time it happened. if it was my car i would take the head off and give it to a qualified engineer to check out , if it is not warped to badly they will be able to plane it (grind it level ).

 between #3 and #4 plus at one waterchannel!

Fixing is easy, but the reason? Overheating while filling water?

no Plymouth, one Dodge 1963, one Chrysler 1964, a dozen of GM, 1000 british of all kind, 1000 european, 80 jewel cars
no rain this Sunday, I loved it!

 last June, after changing cyl head gasket (Mopar NOS) and while refilling cooling water into the radiator,
I got thrilled because the thermostat did open only very late and block temp must have been very high.
Temp Gauge showed hottest

The thermostat prevented the air in the block to exit and didn?t therefore have any contact to water.
At the end, enough heat advanced from the block through the metal thermostat  housing seat,
over the holder of the expansinon unit and at the end to the unit itself: only now it opened.
It opens at 200 degr. F. = 94 degr. C. , which is perfect running temperature

This Friday, only 54 mls later (lots of rain here...) , starting with power on a heavy grade, I blew the cyl head gasket again between # 3 and #4.
Could it have gotten darnage during the filling process? We didn?t smell any oil burning.

Questions:
Do You always fill through the thermostat housing hole before installing thermostat and housing? Seems much safer to me now!!
Does the temp gauge show block temp without water in its tube? I fear, it doesn?t.

This Weekend was Schlo? Dyck Classic days (our Pebble Beach) http://www.schloss-dyck-classic-days.de/
without the Plymouth (yes, I forgot to reorder the new gasket in June...)

Anyhow, a couple of nice shots -50ies  Furniture, white boots, and yes, cars
