Do the lower valve cover bolts get hard to remove? I am working on the passenger side and have all top ones out and the first one in the front, leaving 3. The top were not trick at all and I did not really consider them tight.

I used a 1/4 drive with extension with a 1/4 socket with a 5mm hex insert.

I tried the next 2 back and it seemed like the hex head is not biting and slipped. So I am worried I am going to round out the hex hole.

The manual indicates 77.9 lb/in ( or 6.5 lb/ft) tight.

Walked over to Autozone with the do not have any hex socket combos.

Any advice?
