MACKTRUCKS4 Posted February 24, 2016 Share Posted February 24, 2016 Are the E9 valve covers with the oil fill neck prone to cracking? I have 3 that have cracks around the oil fill neck. Has anyone tried to tig it? Does anyone have one that they are willing to part with? Quote Live every day like it's your last, because one of these days, it will be.

CLEAN is everything in welding aluminum. Quote Link to comment https://www.bigmacktrucks.com/topic/44129-e9-valve-cover/#findComment-325567 Share on other sites More sharing options...

CLEAN is everything in welding aluminum. Exactly. Clean it extremely well and than clean it again.
