Hi All

just had the valve stem seals done on the 429 with the passenger side head coming off due to a broken bolt.

That is all done and back together.  Now one problem leads to another.  The engine will not idle

or idle adjust as it should.  If I screw the main large idle adjust screw in on the carter the engine still

runs - if I turn the drives side smaller idle air adjust screw all the way in the engine does not stop.

There is a noticeable flat spot right at bottom of idle on take off and the engine just is not right at least

at idle.

Is this an indication of a vacuum leak?  The problem is still there if the PCV valve is off and blocked,

same with other vacuum lines.   Hope that makes sense and I can get some advice.

Great to hear John. If your vacuum advance is original to the car I'd test it with a small cheap vacuum pump. It shouldn't leak down at all. My car ran fine but the vacuum advance was no longer working and was leaking. It ran even better with the fix.

Oh geez, it looks like Tony was correct..... we'll never hear the end of it now. :-) LOL

For sale: 1963 Cadillac front center impact bar $100 + shipping

Posted by Lee Martin on April 3, 2018 at 2:12pm 0 Comments

Offering this newly re-chromed 1963 Cadillac front center impact bar for sale, $100 plus whatever it costs to ship it from Detroit to your location.  

The unit fits perfect on driver's side but does not sit flush on passenger side.  I am told someone needs to take a wooden block and hammer and bang the passenger side lower corner in to make it fit right.  If you know how to do this stuff, this is the piece for you.
