1964 Cadillac AC with a 7 port Vacuum control valve

Is anyone having the same problem I'm having ? In park with AC on no vacuum at the fast idle diaphragm, ( so the fast idle diaphragm is out and bumping up the idle) when I put it in drive I'm getting vacuum there. So in park with the AC on the engine is idling at 900 RPM's put in drive it drops down to 450 600 ish. So when your sitting at a red light it feels like the engine is starving for fuel not to mention it's running hotter than it should.…

Can't sleep thinking about my car, am I alone in this ?

I have had my 64 13 years and I think I might be on the right track to fixing my AC. I think I might have the vaccum lines going to the check valve before the neutral safety switch at the bottom of the steering column in the wrong configuration and Im not sure where the black line going from the power servo rotary valve number 6 vacuum line is going.

Oil pressure

I got my car back after the engine rebuild and with 10w30 oil in it when I drive on the freeway after 20 minutes the oil pressure goes from 28 lbs to 22 lbs and at idle the oil light comes on.
With 20w50 it says at 28 lbs on the freeway & at idle 12 lbs
Has this happened to anyone else ? Or can anyone tell me why ?

1964 Cadillac engine rebuild up date

To start, On January 1 My girlfriend and I were heading to my friends beach house in Melbourne shores FL. About 8 miles from the exit on I95 I heard a noise that sounded like road debris hitting the bottom of the car. As I would pass other car's, to be honest as they would pass me I could hear the sound of my engine bouncing off of their cars, it didn't sound good ! I stopped, looked under the car, nothing, lifted the bonnet ( nod to Mike & Ed WD ) no oil spray, checked the dipstick…

Oil light staying on at start up

I had a crank shaft installed in my engine 4 years ago, for the last year or so my oil pressure light has been coming on & staying on at start up of at least 15 seconds. I read on here someone was having to same problem. It was suggested that the pickup tube or the screen might be blocked. I had a shop remove the oil pan & check for this, they found both the pick up tube & screen clean. They also found that where the pick up tube connects to the engine their was no O ring &…

Birthday wish

Today is my Birthday, last week my girlfriend asked me what would you like to do on your Birthday ?

I said (with out hesitation) I would like to get the rear tires on the Caddy balanced.

She looked at me disapprovingly and said Really  !

Posted by Bob Pontius on April 8, 2021 at 3:07pm 1 Comment

Jason, I liked the detail and information you have provided. I would like to do mine similar to yours. Can you help? Do you have trunk material? OPGI is sending the trunk product for my 63 Fleetwood. But it does cover the entire trunk as yours was done. If you do not have can you give me a reference? Thanks!! Bob

Car lift and jack stands

Posted by Les Eastling on March 23, 2021 at 10:00am 4 Comments

I mentioned during the 63/64 chapter zoom meeting on 3/21 that we had installed a car lift in our garage. Someone asked what kind and I didn't have the info at hand, so here is a link to it and also a link to some tall jack stands we use to add more stability to the car and an additional safety factor. There is something about getting underneath one of these cars that makes me a little nervous! …


Leaky Freeze Plug

Posted by Lee Martin on March 22, 2021 at 12:49pm 7 Comments

Just developed a significant leak coming from a freeze plug right over the starter.  Would this be considered a "cam plug" i.e. like Dorman 17616DS?  Our cars have multiple sizes of plugs on engine block and I want to get the right one.  Also, does anyone know how pricey this is for a shop to fix?  Thanks!
