GL1800 Goldwing Back…

I picked up my GL1800 Goldwing from the dealership yesterday. The work looks good, I did have an issue with a burnt out rear light bulb on the lower bottom side. The bulb is a common part that I was able to get down the street at the local auto parts store.

1948 Chevy Edelbrock Carb…

I’ve been working on a off idle surge condition that is consistent and occurs approximately 1100 RPM’s. I’ve tried various fixes with no luck. Listed are the attempts: tuned A/R mixture and idle using vacuum gauge and tach. I was able to achieve good vacuum at 15-16 inch HS. Set timing at 16 degrees before TDC. Replaced accelerator pump spring. Replaced replaced HEI springs for weights to a stiffer type.

1948 Chevy Sedan Exhaust Leak…

I had this very annoying exhaust leak since I got the car a couple of weeks ago. It sounded like a tapping lifter or exhaust leak. I used a piece of heater hose about 3 long as a listening device. I had one end to my ear and the other probing the motor as it was running. If you use this method remember to mark one end of the hose with a piece of tape so that it’s the side you use all the time. After extended use the other end will pick up oil that will be transferred to the side of your head 🙂

It was obvious that the ticking sound was coming from the driver side. After probing around I found it to be in the area between cylinder number 5 and 7. I tried to tighten down the area but the leak was still loud with no change.

I purchased a couple of gasket for replacement. I bought two types a single large piece and the cheap individual port type which turned out to be the version that was already installed.

These older motors are cast iron and back in the day a gasket wasn’t even used. The heads and exhaust manifolds were true and no gasket was needed. After time the machined parts would warp and imperfections would arise. If I was to do this work to original specification I would pull out the manifold and have it machined. If that didn’t fix it the head would have to removed. For an exhaust leak, I chose the cheaper and easier fix using a gasket.

I’m just glad the ticking sound was a simple fix and not a failure that would cost more time and money. My next thought was a loose valve stem and that would have required more work.

Once the project was complete it didn’t change the look of the motor too bad. If you knew to look for it you can see the bright gasket material. At least you didn’t hear that annoying tick anymore.

 

Toy maintenance day…

Worked on several projects with the fellas today. Activity for a 1948 Fleetline Coupe, 1948 Fleetline Aerosedan and a 1964 Chevy Chevelle.

I have most of the tools to perform common mechanical repairs that are not lengthy in repair time. I don’t have the room inside the garage to do a full blown out motor removal and still be able to have both my classic inside at the same time. This rules out major motor work unless I plan to have one of the cars out overnight.
