Anyone know where i can get these allen head plugs at? Im missing one on the back of the head just above the left upper manifold bolt to. I'll post that pic as soon as it loads. Tried to get them from a friend with spare head but all of his broke on the way out, so yeh.....


any help would be just great

 

were did the plug go

 

Best bet is to go to the dealer and find the part number then goto gmpartsdirect or call crateenginedepot and order it through them.

 

tried that no luck. Cant find anyone who can find the part #

 

bump

 

jb weld

 

go to a bolt store
that specialised in
bolts.

 

holllld on, there HAS to be a part number for that galley bolt. dont just give up on the man lol.


Not sure where to look tho

 

This might help thank me later.

^^^ thank him,


literally every single bolt and nut that a car is made with has to by law be made available. just a pain to find them

 

no
tried the local one they dont have much metric. the biggest of that type they had was a m8...i need m10x1.25 and m12x1.5
ive look through all of the GM stuff without luck thats why im on here.
tried them\ have a parts person(good friend) that tried for a week with no luck. I also have all the shop manuals and spent a long time looking and i dont see them. But if you do just let me know

 

bump i cant work on my car till i get these

 

Can we get another picture...im having trouble picturing where this is located....i have a spare head outside

 

its on the drivers side of the head just below the intake cam end cover plate.

the other one is on the back of the motor just above the top left exhaust header stud.

 

the back one

 

im willing to pay a finders fee if some one can get me these

 

I will see if I can find something more, but I did come across these two part listings. I don't know if they are the right part, or if you can find either of these parts, but it sounds like you are looking for anything to try.

Plug-Cylinder Head Core Hole 12791923
Plug-Cylinder Head Core Hole 11101971

 

just wondering how did it come out just a pull or a screw? because something like harbor frieght or merals autosupply sorry for the poor spelling should have them for like 5-10 bucks

 

Is either of these what your looking for? If so part# for the long skinny one is 24418771.... for the short stuby one is 11588880

Hope this helps...

 

Could it be a blow out plug?
Where it's not really a bolt at all, but mearly a designated weak point
so that if the engine gets too hot or something, instead of warping or
cracking it just pops that thing out to prevent further damage to the engine.

 

24418771 is the timing chain tensioner plug, and the other is an intake manifold stud. I know that neither of those are the part he is looking for.

 

its some sort of metric pressure plug i think but idk. what ever it is the back is a 10mm and the side is a 12mm.

 

Do you have a "less zoomed in" pic?

 

went to Earl's and found some plugs. The one by the intake cam is a 12x1.5 and the one on the rear of the motor is a 10x1 if anyone wondered
