Talking Did a compression test today...

perfect compression across all 4 cylinders after 3000 miles of boost and no signs of det on the plugs.


Only problem and here's my question. I have NGK plugs and when I put them back in they hand tightened all the way but locked up and I couldn't really even torque them down cause they wouldn't move. Almost like they were cross threaded...but I'm 99% sure they're not. It seemed like they were completely sunk...

Sorry for the n00b question, I've just never really put plugs back in, always replaced them when they were out.

The plugs have crush washers on them. Thats why the first time you used them you could still turn them after they "bottom out" into the head.

The next time you put them in, the washer has already been crushed so you cant really turn them much after the "bottom out". You should use a torque wrench rather than a certain number of turns to tighten them up.

Cool that's what I was thinking. And I did torque them to 15 lb ft.

Thanks, I appreciate the help!
