GEN IV knock sensor swap to GEN III knock sensors

drill bit size was an 11/32 its just enough to knock the current threads out, tap with a 10x1.5

tapping is a slow process...so be sure not to thread it at an angle. i used liquid wrench that i "Borrowed" from work. it works really good. when the tap starts to get hard go in reverse then go forward again. make sure to blow the hole out with air or your gonna pack all those shavings behind the new knock sensor :rick

installed, pretty simple. use a 7/8 wrench and dont feel like you have to tighten it so tight you'll bust a blood vessel it's a pretty simple snug it down method

onto the cam install of the GEN IV it's simple as hell too once you get the pulley off.

pull the pulley off and prep up with a 10mm deep drive socket and a 6" extension or just use air tools your choice.
pull the cover off. on the GEN IV the oil pan gasket wraps around the front where the timing cover would be. only use a few dabs where the factory used it, i also put a small dab on the corners where the block meets the oil pan and timing cover.

gotta love a 1 bolt cam

pull the retainer plate with a TORX bit..i didnt pay attention to the size, but i can look if anyone really needs it.

if you dont have the cam tool like i didnt, just throw the cam bolt back in and walk it out VERY slowly and supporting it so it doesnt have to rub on the cam bearings a lot.

i soaked the cam in COMP CAM LUBE just to be on the safe side. went back in the same way it came out..nice and slow.
i cleaned the threads of the retainer plate and used a SMALL dab of Red Loc-tite on it. i understand the factory used blue or green. i dont care red loc-tite can be used but you have to remember to use VERY little thanks to how strong it is.
put everything back nice and slow take your time.
i dont have an UD pulley on this motor but i used the ARP 12 point crank bolt anyways. i pulled the pulley in then backed the bolt back out and used liquid wrench on 1 1/2'' of the threads and ran it in until the pulley stopped at the old marks the seal made.

not too bad for a first timer and having to run and get parts PLUS help a friend take a water pump off his truck. then the fiance' was home when i got back and had to eat lunch with her and spend time with her..damn women nah im playing...i enjoyed taking a break :matt
