Source for engine baffle ignition wire seal

[Mike R]

I used these during build, now 20 years later I’m replacing engine and needs to get one of these. I think I got them from aircraft spruce, now I don’t see them in catagolg. Any one know of a source? Thanks

These are slightly different shape but may do the job?

For a four cylinder engine you only need a round hole. Spruce should have them IIRC they are a Slick part.

I just couldn’t stomach the cost of the plastic baffle wire bulkhead’s so I made some from scrap .063 aluminum and some grommets. Total cost less than $5. Here are some pix.

Beautiful Marc.

Now, about those zip ties holding the ignition wires to the motor mount... Switch out to double MS21919-WCH cushion ("Adel") clamps. The WDGs will out-gas and leave ugly brown stains in the powder coat.

Hello, what type of cushion clamp should we use in the engine compartment; MS21919 WCH or WCJ. I will be using Phillips Victory 20W-50 oil, 100L fuel and High Temp brake fluid from Berringer MIL-PRF-87257 / FR257. I also rinse my engines after work / oil changes with Mineral spirits.

Thanks

I used -WCH for its heat resistant properties. Currently my engine compartment isn't "contaminated with petroleum fluids." (yet, maybe never...) Once I start leaking fluids I may change to -WCJ's or not.
