Ive looked this up but nothin really helped me, I just need some input from people who have had the same problem. I broke a cam cap bolt and its in pretty deep. Its the longer bolt of the two. Does anyone kno the easiest way to get it out before I go and try it myself?

thanks

 

PB Blaster and a left handed tread drill bit. make sure its center though so the threads dont get screwed up

 

wut is pb blaster? i heard about using a left-handed drill bit but how will it work?
i dont need to use an ez-out? and also the bolt didnt break that straight, its gonna be hard to get it center

 

PB Blaster is a rust/penetrating oil. ez outs are basiclly left hand thread drill bit.

 

Post a picture. Can the cap be removed to get to the bolt?

 

ya, ive already removed the cap, it makes it a little easier to get to the bolt. so how much do i drill into the bolt?

 

USe a bolt extractor. It is essentaill a tapered left-handed drill bit. It will loosen the bolt as it drills into it.

 

ok thanks. anyone else have any input?

You should be able to pick this up at your local hardware store. Same thing happened to me once, and it's what I used to extract the broken bolt. When you use it, just make sure to have your valve train covered with a towel or something so you don't get metal flakes in there.

 

ill try somethin, thanks

 

well, ive tried everything and the **** isnt comin out. I dont wanna take the head off and take it to a machine shop, so i was thinkin of just using one bolt and sealing the other side of the cam cap down with something. does anyone have any idea if that would work for now? i dont see it being too bad. I plan on gettin a vtec head later on anyway. has anyone else had to settle with doing what my idea is? has it worked?

 

The grabit bit should've worked for you - unless you also managed to cross-thread the bolt. And if that's the case, then a machine shop is probably your ONLY option.

 

Post a pic, if you have access to a welder, weld a nut onto the bolt. The weld will only weld the nut and bolt, but the head will be fine since it's Al. I've done this numerous times on Al blocks and heads.

 

isn't there a dowel pin over each of the cam cap bolts?

that would complicate things

Nope

 

the dowel pins are easily removable anyway

 

i know, but the base is machined perfectly to accept the pin

if you can get the dowel pin out. try and drill out the bolt, tap one size larger (yet small enough to fit thru the dowel pin), insert a heal-a-coil and thread in a new bolt

 

i would try and drill it out but dude i talked to at a machine shop said i need a drill that can spin 30,000 rpm. is this true? will an electric drill work? how do i know how far to drill down?

 

that's a load of BS for sure. the problem is being able to drill it out straight enough. it is entirely possible that you could drill just enough of the bolt out to leave the threads in place. it would be very difficult to do that tho with a hand drill.

if you have the part of the bolt that snapped, measure it compared to one that is not snapped... take the difference and that's how much bolt is in the head.

 

ya drilling in straight is gonna be tough, i dont wanna start drilling in to tha actual head itself ya kno. and i need carbide drill bits rite? do u kno wut exact size bit i need to use? and wut size heli-coil do i need? thanks for ur help

 

take a pic already, or do like i told you and get it welded.

 

best pictures i could get

 

^^^ That is ugly. Try the drill extractor and hope for the best. Most likely, the threads have galled.

 

dude i did the same **** just use a ez grab it and like buddy said get some rust buster. it will come out u just gotta get your ***** together

 

ive already tried that **** and i think ive messed it up beyond oblivion
