Engine and machine shop tips and tricks.

Valve Keepers Can Go Flying

I use my magnetic screwdriver with a small diameter Phillips bit to collect the valve keepers as I compress the springs on overhead cam cylinder heads. The small Phillips bit becomes magnetized when it is inserted into the magnetic screwdriver, and it is small enough to reach into the retainer and remove the keepers from the valve stem before they have a chance to go flying.

Oil Passage Cleaning

When the passages are needing a little extra cleaning, I cut the eyelet off the end of the metal oil galley brushes so I can chuck them into a drill. I have found this method to work much better than by hand.

Damper/Valve Guide Install Tool

We are a two-man shop, so sometimes wrestling a large cylinder head in the shop press is a bit sketchy.
To reduce risk of injury or damage, we installed the guides using our harmonic damper installation tool.
It may not be the quickest method, but we feel it is the safest for a large cylinder head.

Magnetic Tool Holder

I’ve had this inexpensive magnetic welder’s square for years and have never found a good use for it, until now. This red magnetic square saves time spent bending over to retrieve the tools off the floor after blowing off chips from drilling and can be used to hold tools on other machines too.

Flash in the Drain Pan

I see a lot of people struggle with iron parts flash rusting after spray washing and rinsing with hot water. If you finish rinse with cold water, and blow it off, it pretty much stops the flash rust before it can start. You can then spray some rust inhibitor on it if you choose.

Rottler HM3 Hone Repair

Here is how you can repair your Rottler hone head since Rottler does not service this any longer. Use a Regis part number RSI218. You will need to drill out the top of the pinion to remove the expander nut. Then, cut the top of the shaft and drill and tap it for a small bolt. Then, put on the bolt and washer and you are ready to go.

If I’m not using torque plates, I tape up both sides and trim out the bores. I use painter’s tape, which comes off easily and doesn’t leave any glue residue. I get much less oil in the spray washer this way.
