Pegboard in the Garage and Snags Tearing Down the Pontiac 301 Turbo
This Memorial Day weekend I got to do some work around the house. My initial plan was to start building the Pontiac 400, but I recently discovered I needed one more part (Cam thrust plate) and it did not arrive yet, so I decided to work on the firewall and other various little parts on the Trans Am. After spending about an hour in the garage moving stuff around, I decided to switch my car project to a Garage improvement weekend. By Monday I installed 64 square feet of pegboard and enough hangers/hooks to get just about everything shy of 15 pounds off the garage floor.
On Monday I started work on tearing down the Pontiac 301 Turbo. If you’re not familiar with the Pontiac 301 Turbo, it was made in 1980 and 1981 for the Pontiac Trans Am and Formula making it a rather rare engine. Some say it was ahead of it’s time, others say it was plagued by it’s oil cooled turbo charger. It was the last true Pontiac designed V8. What ever your thoughts on this short lived engine are, once I confirmed that my Trans Am was not a special edition, I decided to swap it out with a Pontiac 400. Since last fall this V8 has been sitting in the garage just taking space. This weekend I decided it was time to take it apart to see what was wrong with it and recycle what ever parts that can be reused. Believe it or not, this engine shares a lot with it’s larger cousins (350, 400 and 455) such as engine mounts, fuel pumps and the bell housing.
During the initial tear down I ran into a couple snags. First was the flywheel bolts having 12 point heads. My plan was to use my compressor with the impact wrench attached. My plan went foul once I discovered that the impact sockets I got with my compressor are all 6 point. A run to the neighborhood home improvement stores showed me how rare 12 point impact sockets are. I do understand that a 6 point socket is better for 6 point bolt heads and that’s most likely why the 12 point impact sockets are hard to find, but come on, someone has to sell 12 point impact sockets! When you’re dealing with a 12 point bolt head, you can’t use a 6 point socket.
So after doing some online shopping, I found that only a handful of tool companies make such sockets. Sadly most all of these sockets are through brands like Snap-On, which make the tools too expensive for a weekend mechanic like myself. I did find a set of 12 point SAE impact sockets on Amazon.com that meets my price range. (see picture). They also have 12 point metric impact sockets.
The second snag working on the 301 Turbo came when I made a rookie mechanic mistake! I am using an engine leveler for lifting the motor, that way I can easily level the engine with the engine hoist/cherry picker. I recall today reading somewhere “Always connect engine levelers and engine hoist chains using grade 8 bolts to engine heads. Avoid connecting to bell housing or aluminum intake manifolds when possible“. Well I learned yesterday the hard way why you don’t connect your engine hoist to the bell housing! When I got ready to bolt the engine to the engine stand, you can guess the colorful language that came out of my mouth! Lesson learned the hard way, never never NEVER ever use the bell housing when lifting an engine!
