throttlebody coolant bypass/vacuum q/a
just wondering what every1 uses to plug the 2 holes in the back of the cylinder heads.
i am guessing the original bolts are way too long. should i use like a npt plug or just match up a different bolt and use some sealent on it?
also the seems to be a 3/8 vac hose on the tb below the pcv hose and above the coolant hose on the passenger side. is it for the ccp perhaps? or maybe the other end of the pcv system?

do NOT plug those holes, you need them and the steam line that comes forward along the passenger side cylinder head. the TB bypass is just that, bypassing the ports on the TB and connecting the steam line directly to the coolant lines or the radiator depending on how you have it hooked up
