four questions

I don't remember looking closely enough at crank when I installed it but even if the holes for flexplate go all the way into the crank case wouldn't thread locker still stop oil from seeping out? I mean it's thread locker. It's in the threads and it can't go anywhere?

Check out the picture of my 5.3.....

Now I don't think those are blind holes. What say you all, friends?

They don't look blind due to differences I'm seeing.

I do think threadlocker would prevent oil from getting past the threads. Did you use threadlocker?

Did more research. The holes in rear of crank for flywheel are open to the crank case. The rear main bearing is right there spewing oil at xx psi.
Blue lock tight gel is what has been recommended
And the center plug is pressurized

I did but I'm wondering if I used enough and if the female threads were cleaned well enough to help thread locker to seat/bite properly.

I didn't chase the threads in the crank when I swapped to the 6.0/80E flexplate. I'm pretty sure I re-used the stock bolts. I may have wire wheeled them. It's hell getting old. I don't remember. Mine is not leaking.

Well son ofa gun, I never noticed that when installing my flex plate! However, I bolted on flexplate while on the engine stand, but I know I put loctite on the bolts per assembly instructions I had on hand.

I hear ya on the age thing. To scary jello I'm sorry we kinda hijacked your thread.
Texas when you observed the leak what did you see?
Mine is just a small maybe inch and half puddle after a minute or so run time and it only appears after motor is off. In other words if it were my seal or anything on rear of crank wouldn't it be spewed everywhere?
I see one trail of oil maybe quarter inch coming down rear pan.

Yeah, those holes are definitely open. Here's another pic from my project.....

I'm not sure, but looks to me these bolts are stock and I sure don't remember buying new ones....
