I have a 64 and the timing is to far advanced the vacuum advance hits the valve cover I think this is a result of my father in law having a timing chain put on years ago what is the best remedy ? Pull out housing and reposition it ? Also trying to figure out if maybe they installed the wires wrong where exactly should rotor be pointing on TDC ? and is it possible if it was installed off that the wires could of been moved on the cap to make it run .have had this car 27 years and always runs hot and won't start till the engine cools down ( like it is to far advanced haven't thrown a light on it yet I am doing my homework so when I tackle it I am prepared I have seen the diagrams here but doesn't really show clock position of rotor on tdc any advise is appreciated
OK thnk I got the reply and post down sucks being newbee
You must have a 1964 series 62 car as they came through with the Jetaway transmission that was used in all Cadillacs from 1956-63 and the 1964 series 62 cars. DeVille models had the new Turbo Hydramatic which today we call the TH400.
If you have access to a shop manual, there is a section in there regarding adjusting the linkage to the transmission. I would be that if you Google it, you will also find the answer.
This site is great for tech advice, don't be shy. There are always people willing to help you keep it alive and if you decide to sell, there is a section on the site for that as well.
All the best,
OK I am back at it this thing is just Idling to fast I got totally fed up with it last time now I have to do something with it but if it runs for 10 mins it is to hot to restart It starts and runs fine It is just to fast at idle I am at wits end and this car will be causing to have a stroke I know there must be answers I just can't find them the carb linkage looks nothing like any posted and the motors manual I have doesn't address this problem
Steve, these cars can be frustrating for sure! For now, you can disconnect the throttle linkage entirely in order to idle the engine, set the timing, adjust the carb etc. It sounds like someone may have switched the linkage on you or it is way out of adjustment? Super fast idle could also indicate a vacuum leak, especially if you hear a "whooshing" sound around the base of the carb.
If you could post a photo of the linkage that may help with diagnosis or identification.
Thanks I will do that thank you very much for responding
here they are
OK I found it was a cracked hose going to the PCV valve and a bad PCV plugged the port on the carb now my question is where does the PCV go it appears to be a hose that disappears under the intake . also can some one point me to detailed instructions for adjusting that TV down shift rod my car is holding gears to long I let up on petal and it shifts a little like a bad modulator valve on a ford ( my motors only shows a picture of it ) Thanks all for your help
Steve, you are correct. The PCV hose connects to a breather tube under the intake manifold, towards the rear of the engine. To access, you will probably have to remove the intake. You may want to replace the hose at this point since you are digging in this far and probably do not want to touch it again.
You said you have a Motors manual? I am not sure what year manual you have but the shift linkage from Cadillac '56-'64 Hydramatic (Jetaway) are nearly identical and you can look at the transmission section of the manual for any of those years to see the correct adjustment. Your transmission was used on the series 62 Cadillacs in 1964 and was called a Hydramatic whereas the identical transmission was known as a Jetaway when used in Olds, Buick and Pontiacs. This was the last year Cadillac used that trans in any cars as the Coupe DeVilles used a TH-400 in '64 which became standard across the board in '65. Best of luck!
The PCV was spliced into that hose and tucked under the manifold the hose going under seems OK I just caped the port on the carb to get it to the right Idle when the new PCV comes I should be able to cut that hose back a little and make a new piece between the PCV and carb as far as linkage gonna dig into that next I know one way is faster and the other slower Thanks for the info I greatly appreciate it
What model is the car and where is it located ?
not sure no name on it it has 4 doors cloth seats and that transmission pretty sure the engine is a 390 her grandmother bought it new in 64 it has been garage kept iout side Chicago since about 1980
