Chrysler 4.7 Spring compressor comparison.
I just changed my valve spring seals to stop an oil burning issue with my Jeep Grand Cherokee Laredo 4.7 HO engine. This is a comparison of the “new tool “and the Miller 8387 tool used on a Jeep 4.7 HO V8. I found that the Miller tool was more difficult to use but it was far stronger and compressed the springs straight down so there was less interference for installing the valve spring keepers. The ‘new tool” unfortunately deformed with each spring compression and had to be straightened in a vice using a big screwdriver before proceeding to the next spring. Hank Cullen told me that the new tool would not deform while being used on my engine and was kind enough to send a free second tool when the first one bent. However, the second tool was no better. Hank also told me that the valve springs for the 4.7 HO are the same as the springs on the regular 4.7 engine. I later learned that the HO springs have a higher spring rate which probably was the reason the tool deformed under normal use. See this link for explanation of the up rated springs on the 4.7 HO. http://www.wjjeeps.com/ho_engine.htm The two “new tools” are now somewhat worn but could still be used on a regular 4.7 or the 3.7. Let me know if you want them for good price. The Miller 8387 is also available for a good price. rwdaven@yahoo.com
