riceline Posted April 25, 2005 Share Posted April 25, 2005 any good hardware store should have ezeouts Link to comment https://www.sau.com.au/forums/topic/71414-snapped-bolt-on-cam-bracket/#findComment-1317044 Share on other sites More sharing options...
MonstaS4 Posted April 25, 2005 Share Posted April 25, 2005 How the hell did you snap it? They're only meant to be torqued to 10Nm or so. Link to comment https://www.sau.com.au/forums/topic/71414-snapped-bolt-on-cam-bracket/#findComment-1317115 Share on other sites More sharing options...
warpz0r Posted April 25, 2005 Author Share Posted April 25, 2005 i was tightning them with 1 hand until it was firm and then pop..... i thought the valve or whatever it was called was going down but no, the bolt broke.... anyone have a spare bolt for the cam brackets? or will nissan charge me like $94.86 for 14 of them i dont need?

carl h Posted April 26, 2005 Share Posted April 26, 2005 get a set of these: http://www.partsamerica.com/ProductDetail....rtnumber=T73151 they are far superior to the easy outs and work a treat, especialy on exhaust manifold studs.

Beer Baron Posted April 26, 2005 Share Posted April 26, 2005 be very careful using the ezy-outs or the things posted above (which look like ezy outs too). if you snap the ezy out you are f**ked. be warned.

warpz0r Posted April 26, 2005 Author Share Posted April 26, 2005 yeah, thats similar to the thing i got from bunnings the other day.. havent used it yet... either way, i am f**ked... i have to either drill and re-thread the hole and use a bigger bolt, or try using an easy out.... but the main question is Does anyone have a spare cam bracket bolt i can purchase off them, or a part number for nissan... (or will they only sell me a pack of more than 1?)

Tommyk Posted April 26, 2005 Share Posted April 26, 2005 drill it out and just leave it as is ? Link to comment https://www.sau.com.au/forums/topic/71414-snapped-bolt-on-cam-bracket/#findComment-1319973 Share on other sites More sharing options...
warpz0r Posted April 26, 2005 Author Share Posted April 26, 2005 yeah, but if i drill it out, wont there still be some of the old bolt left in there? and also, i could damage some of the tread the bolt would attach it self to.... atleast if i use a easy out tool, i just have to drill a small hole into the broken bolt, then easy it out.... its about 1.5cm into the head, so might be a little tricky Link to comment https://www.sau.com.au/forums/topic/71414-snapped-bolt-on-cam-bracket/#findComment-1320052 Share on other sites More sharing options...
Tommyk Posted April 26, 2005 Share Posted April 26, 2005 fair enough On the centre cover (on a gtr) covering the spark plugs, i had one of the allen nuts stuffed. I drilled through the head part and the cover came off. Easy - no probs Im guessing the cam cover must be slightly different on a rb25/20 ?

warpz0r Posted April 26, 2005 Author Share Posted April 26, 2005 this is the cam bracket that holds the actual cam down... its one of the bolts that holds down the exhaust cam bracket Link to comment https://www.sau.com.au/forums/topic/71414-snapped-bolt-on-cam-bracket/#findComment-1320115 Share on other sites More sharing options...

Roy Posted April 26, 2005 Share Posted April 26, 2005 If your going to replace the cam journal/cap, whatever they are called...be sure that it is toleranced for your engine. I ran into troubles when i used one of another engine on my otherwise perfect RB20. I wouldnt think its overkill to drop off to a mechanic to be sure that the tolerances are all ok...as from the factory the gallery for the camshafts is line bored/honed (whatever the proper term:)) so sure its a bugger and agro, but best be sure:) Link to comment https://www.sau.com.au/forums/topic/71414-snapped-bolt-on-cam-bracket/#findComment-1320154 Share on other sites More sharing options...

Roy Posted April 26, 2005 Share Posted April 26, 2005 i snapped it replacing the cams... not from driving it...want to do it all myself as a learning experience... And whilst i didnt snap the stud, it diud seize in the cap which meant that i needed to source another one. I used a 2nd hand one off another RB20 that appeared to be in perfect nic, but as i said the tolerance turned out to be a bit different...so when car was off at tuners, the inlet cam became hard to turn and just about seized meaning that the cam belt skipped teeth and i ended up with bent valves:( Im all for trying to do yourself, just be sure about the journal size should you decide to replace it Link to comment https://www.sau.com.au/forums/topic/71414-snapped-bolt-on-cam-bracket/#findComment-1320296 Share on other sites More sharing options...

If you notice all the cam caps are mumbered and you must put them back whre they came from otherwise you are looking for trouble . If you must use a new one you have to torque it down then tunnel bore to suit , of course you can use a second hand one and measure the clearence but you must make sure its within specs . Warpzor , the best way to get the broken bolt out is : drill as big a whole as you can without going into the thread , so about 4-5 mm will be about right . Get an easyout and you should be able to get it out . If you drill a very small hole you will snap the easyout . Make sure you drill straight . If you stuff the thread , drill a bigger hole and put a helicoil in there . Whatever you do dont break the easyout in there so dont force it to much and dont use a chinese aeasyout !

browny Posted April 27, 2005 Share Posted April 27, 2005 Depending on how the bolt is snapped off, you might also be able to weld something (like a nut) onto whatever is left of the broken fastener. If you don't really know what you are doing, it might be worthwhile getting one of the mobile thread repair type guys to come and extract the busted bolt. For $100 or so it might save a lot of time, frustration and could prevent further damage. Removing busted easy outs isn't much fun.

blackrb20silvia Posted April 27, 2005 Share Posted April 27, 2005 did the same thing on thursday last week tourqed all inlet up to 9Nm last one just spun in the head them pop thought it was the wrench clicking off but nope!! snaped in the head stay away from ezy outs there nothing but trouble here is what i did a friend of mine made a jig used the cap as a guide made a dowell like object that sliped tightly into the cap taped it through the cap and slightly into the head the jig had a 3mm hole in the dead center once clamed with the cam cap in place with the other bolt drilled really slowly using inox to cool and lube the bit, thi step is done to drill the dead center of the hole other wise there is a chance that the bit will slip and you wont get center, because the bolt is hardened steel and the head alloy, alloy is much softer and the drill bit will prefer this once the 3mm hole is drilled get a hold of a M6 x 1.0mm hellicoil kit hire one if you have to itll save you alot of money, follow the steps drill out rest of hole with the drill bit attached then using the thread tapper cut a new thread all ensuring that you are going straight cut all the way to the bottom of the hole the slowly screw the helicoil into the new thread make sure you clean out the hole before you place bolt back in (another tip is, if you have 1 get a magnet hold it on the smaller drill bit and use the drill bit as a magnet and get all the fillings out, also use masking tape and tape over the area so no fillings get in the head) as for bolts use any hardened or high tensile bolt got mine from repco they are M6 x 1.0 35mm witha hardness rating of 8.8 these are common bolts they are the goldy collour ones spoke to an engineer they said thay are fine because of the tension they are at the reason i went this way is that once you have ezyouted the old bolt the thread is ****ed even if repaired has been weekened from the abuse it just coped helicoils are stronger than the original alloy, but i just like to be safe sorry this is such a long wined post but its something that i feel strongly bout Link to comment https://www.sau.com.au/forums/topic/71414-snapped-bolt-on-cam-bracket/#findComment-1321960 Share on other sites More sharing options...
