I spent some time trying to figure out these broken valve cover bolts. Currently the truck is in my shop. Which is under a build out and it will be complete by Jan 5, 2019. So none of my tools have been moved over yet. Just my small stuff to complete this job.
Went to Home depot because I knew I needed a few items to get this done.
-Ryobi right angle drill. (Already have battery.)
-DeWalt 6x1 tap and drill set. (My old tap was beat.)
-Dewalt handel.
-Irwin HSS drill bit set. (My buddies.)
-Milwaukee Titanium impact drill bit set. (Already had.)
Just took my time and started with the small Irwin HSS drill bits and worked my way up to 13/16 Milwaukee impact bits. The Milwaukee bits are shorter so I could get the drill in at the perfect angel. Once I got through, the new DeWalt M6x1 tap went in with no issues. Just made sure I had plenty of oil to keep everything lubed.
Success!!!
The two front bolts weren't to bad since they were pretty accessible. The third bolt is the last one closest to the fire wall on the bottom. Will have to deal with that one tomm. The Ryobi drill is to big to drill out the last bolt properly. Will have to ask a few of my mechanic buddies who do this for a living for advice. Also had a chance to stop by my local Toyota dealership. Order nine new valve cover bolts and few other odds and ends for this little project. Should be in by Tuesday so I can get this truck up and running again.
