Whats the worst...
 

Fastoner you came across whaile repairing your car?



I just spent about 3hours getting my old O2 sensor off today. It was the original sensor with 137,000 miles on it. NOT fun, But very rewarding as the car runs great now.

12 point header bolts on my 82 f150... Rusted tight of course, damn near stripped them when I went to replace them, and the exhaust gaskets.

PB BLASTER IS THE BEST PENITRATING LUBE!!! Dont use wd40, or any thing else...

pb, non flamibal, non corrosive, and it WORKS!!!

We sell about 2 cases of it a day at work, farm&fleet... Great stuff...

It was soaked in PB, on and off for about a month...



This was the third attempt of getting it off. You know what the inside of an O2 sensor looks like? I know I sure do....
