37s on 20s :dnw:
depends on the brand too, some run small. what wheels you running them on?
need to fix 4wd too chief lol
i do 2500RPM in my 5.3....u should see a lil higher.
replace the oil pressure sensor and take a look at the knock sensors while its out too.
LQ9 MIGHT have an engine oil cooler line running from top of the oil filter to the radiator....if ur truck doesn't have this, pull the cover off ur old engine and slap it on the lq9....OR cut the lines, run 1/2" hose to an external oil cooler.
what huck said...when u pull the intake off, the rear sensor is most likely to have rust on it. get u some/a new one and new harness for them. then put some high temp rtv ON the plug lip, connect the sensor and put round cover on...then lay down a nice fat bead around the cover, but leaving a small gap towards the back so water can get out....do that for both covers.
sorta like this but I do it right where the cover lip is at
THIS
My knock sensors looked JUST like this....front one was fine, rear was FUCKED
That kit works.....the big black plugs have a lip/flap that goes over the valley cover once u seat it in the hole. Put some rtv on the bottom of that lip so it seals between the valley cover and the black plug.
Go fast parts while it's apart!
Oh, I see, the cap has a larger diameter lip than the actual plug. The bed of RTV goes under that lip? Is that grommet called the valley cover? Sorry, I'm not truck motor savvy. And I may only buy one, as they are fawkin expensive in Canada
