Brief Description:
After cranking down on the worm gear hose clamps every time I have the cowl off to stop drips from coming out of the oil return lines I decided there must be a better method. Putting an 8mm socket on an extension is not that big of a deal but the clamps just seem to dig deeper into the hose material. As the hose gets hot/cold and expands/contracts the clamps do not adjust their clamping pressure resulting in the drips I have seen. A quick search on VAF and I came across the idea of using spring-band clamps instead of the worm gear clamps.
After a cursory search for spring band clamps on Amazon I saw a plethora of inexpensive, various sized clamp kits although none made me feel comfortable. They all seemed a bit “cheap”. I searched on McMaster-Carr and found some clamps with product specs listed and opted to purchase the clamps they offered that had a higher temp rating. They arrived 3 days after ordering and look to be quality.
I opted on ordering a better hose as well. See parts listed below.
