A NEW WATER PUMP FOR THE 67 DEVILLE AND DETAILING THE ENGINE

I woke the 67 from its winter hibernation recently. Everything was fine at first... I changed the oil, flushed the coolant and brake fluid and checked everything through. After I finished the annual service work, I started the car again and suddenly the water pump started to make terrible noises. It looked like the bearing of the water pump was shot... It seems to have also started leaking at the shaft...
So I ordered a new, high quality rebuilt water pump from one of my favorite sources.
When I got it, I found out that it was one for a 64/65 Cadillac with an additional water outlet. This seems to be the type everybody is selling nowadays and it is much more common. It will fit the 1967 429 engine and it even has the additional water outlet pre-plugged with a rubber plug. The problem I had with it, is that it looks completely incorrect on the 1967 Cadillac, and so it was not acceptable for me.
I then found
a very good source for Cadillac parts. They are priced higher than other outlets (if you can even find this parts anywhere else..), but David - the owner - offers only 100% correct and high quality parts. He also has a huge collection of NOS parts. I found some parts through him that I did not find anywhere else. His customer service is excellent as well - I can highly recommend him.

Until around 2009 I had most work on my cars performed by a restoration shop specialized in American Cars. Then I decided to no longer go there for a lot of reasons. With the growing numbers of cars I collected, I could no longer afford to pay somebody to have all the work done, and I no longer accepted to pay good money for lousy work and bear the shop owners terrible attitude against his clients.
Now that I´m trying to do everything by myself,
I found a lot of bad work the professionals did, and sometimes I´m really shocked to see what I wasted my money for, but I had no idea about cars and they could have told me everything and I would have believed them…. Lots of work they did leaves a lot to be desired, and you can see some examples in the pictures below…
When they repainted parts of my 67 Deville´s engine,
they used the completely incorrect Cadillac blue, which was used from 1977 on. I always hated it, and now that I had to disassemble so much to replace the water pump they did in 2001, I decided to paint everything correctly.

I detailed all the parts I took off and had them media blasted. After they were cleaned, I painted them with the correct shade of Cadillac Blue. Bill Hirsch engine enamel is the best and most correct engine enamel for Cadillacs. You can see lots of pictures below which document what I did. Besides the incorrect paint I found out that fuel lines were damaged, bolts were missing or broken off and many other small flaws which I corrected now.
I´m now waiting for
the correct upper and lower radiator hoses to arrive, which are reproduced by Fusick, to replace the still original hoses from 1967! The originals still look great and would probably last for a long time, but I do not want to take any chances… I am now hoping that nothing is leaking and that I wont have to re-do any of the work.

When I took the r
adiator out, the overflow tube came loose. I already had the same problem years ago, and it was not fixed properly by the restoration shop… Luckily I found an old gentleman locally, who could brace it back together the old school way. I will of course detail the radiator as well before installing it back into the car.


This is a short video which shows the problem I had with the water pump and the bad bearing. You can clearly see the wobbling of the shaft and hear the shot bearing.

This is how the engine bay looked like before, with everything painted in the incorrect later Cadilllac Blue...

The defective water pump is about to come out. I will also replace the painted fuel line with a correct one from a spare engine I have. The water pump made a loud bearing noise and the shaft was a little loose.edge
I will sandblast and repaint the hot water crossover passage.edge

This is the incorrect 1965 water pump everybody is selling for the 429 engines. It will work with the 66 and 67 Cadillacs as well, but it has an additional water outlet which was not used from 1966 on. If you buy them for your 66 or 67 the no longer used outlet is often blocked like you can see on this picture. The correct 1966/67 pumps are much harder to find and way more expensive.edge

This is how a professional restoration shop damaged the original fuel line when it tightened it 15 years ago during a carburetor rebuild. i think I was lucky that it did not leak and still let fuel through...

I detailed the fuel lines I have from my spare engine and installed these instead..

I changed it back to original with the correct bolts and rubber bushings which I soaked in silicone lubricant for a couple of hours to make them soft again...

When I removed the overflow hose from the radiator the neck came loose. Luckily I found an older gentleman locally, who could brace it back together the old school way. I will of course detail the radiator as well before installing it back into the car.edge
I did not want to remove the front cover so I had to repaint the oil filler tube inside the car... First I brought it back to bare metal.

The distributor after painting. This spray gray paint from Eastwood replicates cast steel very very well. I tricked a lot of people with this paint who insisted that it must be bare metal.

I used Bill Hirsch engine enamel to paint all the engine parts.edge
The new water pump and the mediablasted and then repainted parts back in the car. Also painted the water pump pulley in the correct color now (black).edgeedge
Most things are back together. I am still waiting for the correct reproduction radiator hoses to arrive. I did not repaint the intake manifold in the correct color as I did not have the necessary gaskets to reinstall it. I will do this eventually later, in the case that I have to remove the carburetor...

PAINTING VALVE COVERS

I´m still improving the appearance of my already fantastic 74 Cadillac. I want to keep it as much original as possible, but there are some things which I wanted to improve cosmetically.
The valve covers still wore their original factory applied Cadillac Blue paint which had suffered quite a bit over the last decades. Thats why I decided that I wanted to freshen them up.

Thats how the engine bay looked like when I got the car.

As you can see - the valve covers did not look too nice after all those years…

I bought "Bill Hirsch Engine Enamel" which is the perfect color match among all available engine enamels. Some others are good matches as well, but its said that Bill Hirsch is perfect. Also it seems to be the most durable engine enamel on the market.
The color match is really absolutely spot on. The only "issue" I had, was that the enamel is not exactly easy to work with. I have to admit that I´m not very good in spray painting, so I had to do the covers 4 times until I was happy with them.
I always had some paint runnings or dirt on the covers after spraying on the paint what is of course my fault.
Normally you can wet-sand imperfections out of the paint, but thats not possible with this enamel. You also cant spray over the paint to correct problems as the new paint will eat up the old one and damage it permanently. Its also drying extremely slowly and is extremely soft, so you can get scratches even with a microfiber cloth if you are trying to clean them.
It can take up to 4 months until the enamel is fully cured and hard.
These are things you have to be aware of if you are using this high temperature engine enamel.
I still highly recommend Bill Hirsch Enamel and I would not use anything else on my cars.

Bill Hirsch Engine Enamel - the perfect color match for the original Cadillac dark blue that was used from 1949 to 1976. Make sure to read the instructions before using this enamel - its quite different to use than other paints…


When I took the covers off my car, I media blasted them, as there was some rust on them where the paint has come off. I then used several coats of filler primer and wet-sanded between coats to fill up the former rust pores. So I got a perfectly smooth surface again.
In the meantime I thoroughly cleaned the surfaces on the rocker arms where the gasket was, to make sure that I would get a good sealing once a new gasket was installed.

Completely rust free after sandblasting - but one can see where the rust once was…

After the application of the engine enamel I let the covers dry for 2 weeks before I installed them back into the car. I made sure that the new cork seal was well seated and tightened the screws carefully. You only have to tighten them to 3nm - thats only hand tight. After the first test run they seem to seal perfectly.

Back in the car.

Back in the car - as you can see there are some more areas which could use some fresh paint as well. I will do that later,
