msbulldog601 Posted March 21, 2021 Share Posted March 21, 2021 Hello, I replaced oil Pan gasket on my E7 427 engine because it was leaking one of the bolt hole is cross threaded. I didn’t realize this until the oil Pan was back up and I was trying to put that bolt back in so I pull the bolt looked at it the bolt threads was ok so I shined my light into the hole and saw the threads was messed up. Do you all think I could just leave that bolt out without the Pan leaking? Quote Link to comment Share on other sites More sharing options...
fjh Posted March 21, 2021 Share Posted March 21, 2021 Always pays to get all the bolts started by hand before running them in with a wrench! that said depending where the bolt is it will likely be fine! what do you have to loose, give it a try! 2 Quote Link to comment Share on other sites More sharing options...
Popular Post Joey Mack Posted March 21, 2021 Popular Post Share Posted March 21, 2021 theres been many times I have taken that pan down and there was a bolt missing, and it was not leaking at that spot... theres 30 bolts about 3" apart... should be fine..you could just run an 8mmx1.25 tap in there and fix it with the pan up... jojo 3 Quote Link to comment Share on other sites More sharing options...
msbulldog601 Posted March 21, 2021 Author Share Posted March 21, 2021 Thank you all for your help... in the spot where the hole is located which is up in the front of the Pan I couldn’t actually use my hand I did use the socket and extension to get it started then I attached the ratchet after.... I also thought about trying to use a tap to correct the hole but it’s just the location so I was hoping I would be okay without a bolt being there.

Vmac3 Posted March 21, 2021 Share Posted March 21, 2021 Sounds like the timing cover is damaged. Like F and Joey mentioned, I would leave it alone and see what happens. If it leaks again then I would try a heli coil. V 1 Quote Link to comment Share on other sites More sharing options...
msbulldog601 Posted March 21, 2021 Author Share Posted March 21, 2021 Hey I didn’t mess with it I topped the truck off with fresh oil let it run(idle) close to two hours not one leak hope it will be the same result when I do start up in the morning and actually work it. Thanks again for the help. 1 Quote Link to comment Share on other sites More sharing options...
