0 Mackpro Posted April 27, 2022 Share Posted April 27, 2022 The cam gear sensor sometimes needs shims on it to get it set right , there is a tool to measure if or how many shims are needed. Also did you the cam gear timing tool with the little rod / pointer that goes in the hole in the block ? It’s easy to get a tooth off without the tool . https://www.freedomracing.com/j-44514-b-engine-timing-kit.html?___store=default&gclid=Cj0KCQjw06OTBhC_ARIsAAU1yOVcfK5KSfGydFWvQMI0R_gYML4GjYXgKC3CxHeBBHVSP3olEk9UnRYaAgcTEALw_wcB Quote Link to comment https://www.bigmacktrucks.com/topic/69614-top-tech/#findComment-496157 Share on other sites More sharing options...
