Top critical review
These fit WAY too tight
Reviewed in the United States on August 1, 2019
I purchased these looking at other reviews and because it came with the secondary tensioner tool. These were likely designed to fit just right or close to it assuming the flats on the cams were perfectly parallel. They were not, at least in my case. Once i realized that my cams were not "I I I I" and were more like "\\ //" (very exaggerated) and taking at look at FordTechMakuloco's youtube series, i realized that these tools were manufactured too tightly. His tools slot right on and have a bit of play to them. There is nothing wrong with a bit of a loose fit. It makes the tool easier to use and it makes lining up the main chain easier when you get to that point. It would have to be a VERY loose fit to be off a tooth.
I give them two stars because i was able to use them, though i did lose a bunch of timing determining why they wouldnt go on initially. They did their job, but i had to tap them into place for my initial use. I did remove them at one point and needed to reinstall, so i kissed them with a grinding wheel to loosen them up a touch. They worked much nicer after that. Oh, i did need to modify the secondary tensioner tool as well so it would actually stay in place.
