The tapper i used cracked the threads a little bit maybe a couple threads down 2-4 threads or so im not sure , the car is s4 na


this is on the lim where the rods were that i took out (to remove 5/6 ports), i want to be sure i wont be getting any vacuum leak from this crack i have going down into the threads ... i threaded the fitting in as deep into the threads to go over the crackin to hopefully prevent any leaks

 

I'm not 100% sure what you're asking, but if your'e worried about a vacuum leak becuase of a few missing threads, then just add loc-tite, and "forggitaboutit"

 

u can see the crack from the outside right where the hole/threads are and it goes straight down a few threads str8 down... i just want to make sure ill be ok

also where my gasket(s) go there are some decent size scratches on the surface where the gasket goes, will it still seal ?

sorry if im askin stupid questions, i just dont know that much and im not sure about alot of things...and i dont want to put this stuff on to later find out im getting huge vacuum leaks.... but as longas it will all be ok ill go ahead and put it all on.... i dont know if i would need the loctite or threadlocker or whatever but i could put it on as insurance if u guys think i will get leaks if i dont

 

so i probably wont have anything to worry about ? at least i hope i wont, im just making sure cuz i dont wanna have to take it all apart again

 

Post a picture of the crack? But the casting area around the screw holes is fairly thick, and not close to the inner runners at all. So you're probably fine. Worst case is to just have it quickly welded up, or seal with epoxy.
