WWWPerfA_ZN0W Posted October 27, 2017 Report Share Posted October 27, 2017 It is not tough IF you have avg or better mechanical skill, and you pay attention to the process. Basically, the VCT solenoids are accessible only by removing the valve covers, unlike some of the F150 vehicles. To access anything else in the timing system, the front cover has to come off, and that is accessed through the right front wheelwell, so you will need to use jackstands to suuport your Edge during the R&R. How long have you been using the HM oil,what weight, and why? Once you use the HM long enough, you cannot go back. HM oil makes seals swell. Swollen seals wear faster. Regular oil will then leak as the seals shrink back. What sensor have you installed? Quote Link to comment Share on other sites More sharing options...
colorado Posted October 27, 2017 Author Report Share Posted October 27, 2017 its been 2 years for the oil and did change the camshaft timing sensor. i use 5w20, same weight but HM instead of regular. did it because people told me my engine would last longer because of is kilometers.

WWWPerfA_ZN0W Posted October 27, 2017 Report Share Posted October 27, 2017 Well, the good news is ... I guess that you continued to use the recommended oil weight. The bad news is I would not recommend switching back to regular oil. HM oil really should only be used when you start seeing seeps from seals. Still it is a bandaid in the sense it just delays the necessary repair work. There are two cam position sensors, one for each bank. Not that it matters for this thread ... I think Fordtechmakuloco (?) has a video taking apart a VCT solenoid showing you what goes wrong. But the bottom line is, if you do the work to remove it, just replace it. The parts inside are difficult to obtain, mostly the screen/filter in question. At 200,000 miles, worth it anyway. Replacing the solenoids is the easiest part of this repair. If you want to dig deeper into the phasers/timing chain/tensioners/water pump, you can do it, but it is not done lightly simply due to the hours involved. 1 Quote Link to comment Share on other sites More sharing options...
macbwt Posted November 1, 2017 Report Share Posted November 1, 2017 In the future only use HM oil when you have leaks. As WWW stated you can not switch back. I have 215,000 miles (346008.96km) and I am using the normal full synthetics with no issues. 1 Quote Link to comment Share on other sites More sharing options...
