i bought an endyn catch can used but it didnt come with the freeze plug....i have to go to auto parts and buy it but i dont know the size....i searched but couldnt get a straight answer....some people say 34.3mm and some say 34.6.....does anyone know for sure what size freeze plug i need for a b16 on a 2000 si? thank you, your help will be much appreciated....

 

Go in to Adavanced Auto. They have a box of freeze plugs in metric sizes. Pick the one that is between 34 and 35. Fits like a glove.

 

sweet ill go there today.....

 

went to advance auto parts and they have a kit which bring a couple of different sizes but the sizes were all in inches....they had 1 - 5/8, 1 - 1/2 and up......after converting it to mm it was too big....so i got a 34.3 and a 35mm at napa and i got one of them expansion plugs that has the nut on the back where you tighten it and it expands in the hole for worst case scenario....it would be nice to know the exact size instead of guessing....no one has anything between 34.3 and 35 so i hope one of these work....

 

It should work just fine. Use some hondabond and it should seal it up. My advanced has to bins, one has plugs in mm and the other has it in inches.

 

yeah none of the auto parts around here had anything but napa......i went to autozone, advanced, pep boys, and napa....but thats cool ill post my experience so people can look on here and use this info in case of finding themselves in the same position as me...thx

 

even if you can't find the 34.3 or whatever it is, i've taken a 34mm plug and expanded it enough to get it to seal. kind of a pain, but i ended up using a big socket to tap into the open part of the plug.

 

i have a z10 plug

I used 35mm on this B16a2

 

wow...did u have to hammer the **** outta it to get it inside or was it a decent fit?

 

It is a interference fit so yea I had to tap it in with a hammer. From experience almost every block uses a different size. My Ls used a 34.3. The b16 used a 35.

Couple taps from a rubber mallet. Hope you been working out

 

I used 34.3

 

****, we tried a 34.3 and ended up having to take the whole damn oil pan, oil pick up , and tray off.....it was too loose in there....put a 35mm and hammered the **** out of it until it was flush.....just got back from doing it....ha

 

i just got the z10 plug
just call them up and order one
its $25+ shipping from z10

 

so no jb weld required? just held in from being taped in?

 

Correct. The right size freeze plug taps in. It's a very tight fit

 

Z-10 25 bux damn No one will ever see the it go to oreilly's like I did and spend 25 cents perfect fit call Larry or Josh They will give you the Dorman Part# it really is only 25 cents

 

i spent a dollar each on 34.3mm and 35mm....the 35mm that i put in didnt seem to fit but after hammering the **** outta it, it fit perfect ....put some hondabond on the outside of it and get to hammering that beast in there....

 

How would you get it out if you had to? And were do you get hondabond from. Is it like JB weld.

 

Drop the oil pan

 

u have to drop the pan remove baffle and pick up and work the plug out the galley

 

I couldnt find ANY metric freeze plugs anywhere when i was doing my (go figure no metric in canada) anyways.. I ended up using one of the rubber ones you tighten untill it is tight, but i could only find one size way too small and another too big, so i pulled the rubber off the big one, shaved it down with a grinder, and put it back together, hammered it in the block with a mallet, then tightened her up real good. Its been good so far, its in there tight!

 

just get a 35mm and hammer the **** out of it...after its in there i dont think itll ever come out..

 

hell no that **** wont ever come out un less we pull it out some how lol
