Well, i think  i have the  oil pump cover gasket back on and not leaking,, at least i took it for a short ride, and no apparent hemorrhage,, will go give it a feel and see if any thing is on the bottom of the seams.

my newest notice of things, was after my ride, i can hear the radiator bubbling under the cap.  Car isn't over heating,, staying at the 1/4 mark.  i havent ever noticed it before.  In addition to that, it seems to be coming out of the overflow hose.  When i bought the car, i never did see an over flow tank, and dont remember seeing a picture with one on there, so is there one supposed to be on there?  i have checked the hoses, dont  see any leaking or anything.. 

anyway, thoughts on what causes the radiator to be bubbling,

radiator is a new radiator,, so it shouldn't be crud in the system,, fluid looks green no brown,, it seems to be more of a boiling sound than just a gurgle, accompanied by the outflow through the tube, with no apparent over heat

Do you have a new radiator cap installed? A unpressurized cooling system will boil. If the cap is failing, no pressure is building up.

i didn't put one on when i changed the radiator but i will get one tomorrow,, see if it settles it down,, 

Your neck on the new rad may be longer than your old one. Your cap spring may not be properly tensioned against the neck to provide the proper pressure. You may need to find out what the proper size recommended cap is from the supplier. This would be the rubber part of the cap sealing to the bottom inside of the filler neck on the radiator. 

You are also not supposed to fill the rad right to the top of the neck. It should only be filled to1" to 1/2" below the top of the tank. This allows the fluid to expand and not be forced out the cap. On newer cars its forced to the overflow tank and sucked back in when cooled. The bubbling you hear can also be the rad cooling and sucking air back into the rad.

i had it fill to about an inch below,  so i think i was ok there on that part of it.

i noticed later the level seems to move up and down to a level just under the lip, to down to about  1.5 inches down, I know i had filled it to the 1 inch level.  but it does seem to be moving,

will get a new one tomorrow,  Should i get some sort of overflow tank,, is that something that is an "upgrade",, seems the fluid blows out the overflow hose,, and can make a mess

I'd make sure you have the right size cap before going further. Your old cap may be short. If you have the old rad measure the top of the neck to the sealing surface and compare to your new one.

I changed caps,  seems a better tighter fit.  Took for a longer ride, no heat problems, didnt notice bubbling sound, but,  first picture is what happens when i stopped and shut down.   

Also.  As a follow up to the gasket leaks,  i mentioned the oI'll l looked a funny color, and the shop man said thet used a dye to chase down the leaks, ,,well, its ugly, see pictures, sooo, to make sure something else wasnt wrong, i changed oil, now that current leak search is over.  After driving on couple of occasions, i checked oil.  Seems to hv maintained its light brown color,  im just worried that the antifreeze got in engine, and i hv read that is a head gasket problem, so i will contine to ck oil color.

Any further thoughts on the overflow?

The first oil you removed sure seems to have some antifreeze in it
I think your rad may have boiled over --due to your coolant --being low --in your cooling system ( less than a topped off system coming back from you shop )
The fact that you changed the oil ( a great idea ) and the oil looks just as it should after watching it a while is making me think the last shop was pulling a fast one
Possibly to make you think you have a head gasket issue
Low coolant in rad ( that he did - to have you boil over and make you think you have a problem ) that looks like it has gotten into the oil ( that he added to the oil ) makes it look like you have a bad head gasket to tend to
That i am sure he would love to charge you to fix when it does not exist ( a real quick fix for him - just an oil change )
I hate to be thinking this way but that sure seems to be the case here
Check the oil for a while -- if it looks the right color just disregard the boiling over and the antifreeze in the oil - they were you mechanics doing
This mechanic could just be one of the real bad ones - a blatant CROOK !!
I had a bad feeling that something was not right when you first started to boil over after being at the repair shop very recently

Watch the oil carefull for a while-- that will tell you what you need to know
All looks real good right now -- no issues
Great you took the time to get that bad oil out of the engine
You are becoming a good hobby mechanic to identify that bad oil and react accordingly


The new rad cap SB 12 to 15 lb rating


If they put a fluorescent dye in the oil that woukd be the proper colour of it. If you have any yellow sun glasses it'll look bright green. 

Kim did you measure the depth inside the rad neck to get the right cap? One of two things is happening, you overfilled the radiator or the cap doesn't fit right. 

Adding an overflow bottle is a good idea. It keeps the system topped off, and you can check on the level of coolant at a glance, to see if the coolant is being lost somewhere.

You can rent a coolant system pressure gauge. It goes in place of the cap, and you start up the car and let it warm up. If the pressure stays steady, then the coolant system should be good. If the pressure pulses, then it is an indication of a head gasket leak, allowing cylinder pressure to bleed into the coolant system.

You can also manually pressurize the coolant system to see if there is a leak.

Clovis  the height or depth of the cap hole is 13/16 from seating lip to top.  my cap appears to be about that maybe a shade short so it seems to be a good fit,  

For the sake of knowledge and information to anyone,  

this morning, i took car to gym, but before i went i measure the opening as noted above, and noted the fluid level was very high, like under the lip, just below the overflow outlet.

i know for a true fact yesterday, at some point in between drives,, and the radiator was warm, not hot or not cold, just warm, i took off the cap and noted the level at a bout 3/4 to 1 inch below lip.

My question is,, does the fluid level move up and down depending on when you check  it, like when its been sitting all night?  As i dont really check my diesel truck that often, just a quick glance, into the overfill tank,  since this is gas, i feel it needs to be looked at.

ALSO,, oil still looks a light brown color.. so I'm hoping that isn't going to be a problem, coolant in oil.

Seat belt restoration

Posted by Michael Forte on March 6, 2018 at 12:00am 4 Comments

During the process of a complete restoration (and color change) of my ‘63s interior during the winter of 2016, I replaced the aftermarket seatbelts that were in my car with restored original '64 buckles and retractors.  I had a terrific experience with Ssnake-Oyl Products out of Tyler Texas, so I thought I share the info. 

In my opinion, the '64 seat belt buckle with the Cadillac Crest is the coolest looking seat belt buckle ever put in a car.  Apparently, they're not easy to find in…


Drive shaft Question

Posted by Christopher Belinda on February 26, 2018 at 12:45pm 3 Comments

Good Morning - I have read several, very informative posts on this site regarding the 63/64 drive shaft and am looking for a few recommendations.  My Park Avenue is a relatively low mileage car (32,000); however, in an effort to make this a very reliable, long distance traveler I would like to ensure that this vital component has a clean bill of health.  Normally, this would mean replacing all universal joints, greasing the slip yoke, and replacing the carrier bearing/mount.  As you have…


Air Suspension - How to Choose and Install

Posted by Michael Forte on February 19, 2018 at 10:00pm 15 Comments

What I enjoy most about old cars is that they can be restored to original condition, radically customized, or somewhere between those extremes, reflecting the owner's individual style.  For my '63 Convertible, I want to achieve a mostly original look, with minor custom touches to make it clean, smooth, and low.  This article is to share my experience in choosing and installing the suspension components to achieve a low stance and a comfortable ride.

I purchased my car in August of…
