Well went to change my knock sensors should be simple right. Go to auto zone get 2 put one in torque down to 12 ft lbs. Great. Put other in it broke right off in the block didn't think would be to hard although pointed in center. So get a scew extractor went in little on the side f@ck. Nothing to do now but go with it well extracted broke and messed threads up still haven't got extractor out and left with this unrepairable mess. Taking a break from it right now getting way to mad. My buddy told me to just delete the knock sensors I guess this probally my only option at this point. Or can i just delete one.

Can you get a pair of vise-grips on it? Then turn clockwise to get the E-Z Out extracted.

billymz28

no it broke off in the block cant get anything on it.

Only other thing I could thing of is if I can drill the hole completely out full with jb weld or some kind of epoxy stick the knock sensor in let dry to make it's own threads

G Atsma

OK. I saw the piece sticking out and thought something could grip onto it.

Put the other knock sensor on the front of the head and extend the harness Or just delete them. I deleted mine since if my motor ever knocks at my boost level I'll be picking up pieces anyways.

billymz28

yeah my buddy saying delete it but really dont want to hurt motor over junk autozone part. Pi$$es me off. Mines heads cam and n20. I might try my jb weld method and if dont work then delete

Extend the harness , tap the bosses on the sides of the block and run them like gen4 blocks . That might work !

billymz28

that would result the the motor coming out though wouldn't it.

no nothing stincking out its deep in there not even close

G Atsma

In both pics there is definitely something sticking out of the hole. There is something to grab, It doesn't need to be the EZout

Yeah, I don't see anything to get a hold of either...

Well good and bad news good news I got the broke screw extracter. The bad news broke the boss completely

JB weld it up and as others said you can relocate the sensor or just tune them out.

Move the sensors to the side of the block and slap on a flat valley cover

This is a good solution. That or grind it flat, have someone machine you a new boss, then tig it in place. Option 1 sounds a lot easier.
