First post ever. Looking to share a trick I found to remove wicked-stuck oil pump cover screws that may work for others.

First I read all the other posts in the forum I could find on the subject and found them extremely helpful. I was able to successfully remove all 7 old screws, but not without much effort and stress.

1) I followed the advice on this forum and bought some #3 size phillips screw bits. Mine were Milwaukee branded, found at Ace Hardware. 2 small and 1 2" which I used to hammer the screw heads with.
2) I used PB bolt blaster to spray the screws down over night (not sure it helped TBH)
3) Holding the 2" bit with pliers I used a 3 lb hammer turned sideways to strongly "tap" (smash) the bit into each screw head in hopes to break the stuck screws I am not sure this helped either, but they did seat deeply at that point.
4) I strongly support the idea of tightening the screw ever so slightly to "break" the screw loose. Before trying to back it out/unscrew it. That idea was posted in the forum and is brilliant advice.
5) finally, I took a 15" 3/8 ratchet, a 3/8 to 1/4 extension, a 1/4" socket and my #3 short phillips screw bit and I found a 4 ft piece of window trim wood I had laying around and used it to pry against the drag link and force the ratchet very strongly against the screw. I used so much force I was bending the wood. See pictures. I thought a 1x4 would be too weak and a 2x4 too thick. This piece worked and allowed just enough pressure to hold the ratchet to the screw head.
6) Finally I think I was putting about 30-40+ foot pounds of torque through the ratchet in order to break the screws free. It was shocking how hard it was to break them free. I did nearly round out the top right screw before trying this leverage board trick, but finally got it to break. - brutal.

Anyway - first forum post - really appreciate all the prior posts. I hope someone else finds this helpful. Good Luck - you've got this.

Glad to hear they came out successfully, it's a rite of passage :)

A impact driver will accomplish the same thing, I actually bought one specifically for this task years ago.

Yep. Hand impact driver is the absolute best approach I have ever found for this.

Mark...
 
This job is never fun when those screws are stubborn. The proper JIS bit goes a LONG way to fitting the screws better, but even that isn't enough sometimes. Note JIS ≠ Phillips. If that doesn't work, a left hand drill bit just pops the heads off and then the studs back right out. Cant be tight if its not there...
 
I believe that I shattered two impact bits doing this last year, one of them leaving the bit in the screw. I ended up welding a bolt onto the last stubborn SOB and it came right out. More and more when I have a stuck bolt I bring out the wire feed welder, which has become one of my best tools. It seems that the temp shock of an electric weld is what's needed to break so many bolts loose.
