Sorry to hear abour your mishap  Hope you get it fixed soon and without too much cost. Do you need any bits? Which bolt was it? Do you need torque settings? |

Try using a stud extractor. Same principle - you drill a hole in the broken bolt/stud, but instead of trying to drill bigger and bigger ones, you screw an extractor into the hole. The extractor has a left hand thread, so as you tighten it into the broken bolt, it will unscrew it from the hole. This is a lot quicker (usually!), but more importantly, it does not harm the threads in the hole, which drilling can do. If you do drill the hole, it's worth running a "tap" down it to ensure the threads are unharmed. I often keep an eye on Aldi and Lidl for their bargains and your timing could not be better: Tap and Die set for cleaning up old bolts, nuts and threads, this is bound to be an ideal complement to your toolbox. www.lidl.co.uk/uk/home.nsf/pages/c.o.20090910.p.Tap_and_Die_Set.ar6I paid a lot more than this for mine and for home use, I doubt it's any better than this for £5.99 I have a similar vernier gauge to this (bought in Aldi) for a similar price (£7.99) www.lidl.co.uk/uk/home.nsf/pages/c.o.20090910.p.Digital_Caliper.ar6 I've had it for several years, it's done its job well, easy to use and hasn't gone rusty. As far as I know, it's accurate. This is what we need to measure your disk thickness. They do have a stud extractor set www.lidl.co.uk/uk/home.nsf/pages/c.o.20090910.p.Screw_and_Bolt_Extractor_Set.ar6 but I think this isn't appropriate for your (M6?) problem. This is my set www.screwfix.com/prods/20084/Van-Car-Accessories/Mechanics-Tools/Stud-Extractor-Set-8-Pc?cm_re=SEARCHPROMO-_-STUD%20EXTRACTOR-_-20084 £8.99 at Screwfix Or for £11.48 at Machine mart www.machinemart.co.uk/shop/product/details/cht123-screw-extractor-wrench-setClean up the rubber gasket and see if that cures your seepage. If not, a new one www.wemoto.com/pictures.dyn?u=5835282qqq5828045 for £8.05 from Wemoto is probably the solution. Take care and don't break anything else ;D |

Success in getting old bolt out, seems it was not in there that tight, so after a cpl Min's drilling it moved, so was able to get a very small screwdriver in there and get it out  . Now to get a new bolt and pos a new casket, unless some casket seal will work. So might not be of the road as long as I thought. Thanks McF you help was greatly appreciated. Anyone got a spare rocker cover bolt they dont need ??........lol |

Bravo - well done
That must have been a relief to get the old bolt remains out.
You do need the right bolt, but an M6 long enough (and not too long!) with the steel and rubber washers might be enough to help you until you're sorted with the right bolt. Be very careful not to overtighten.
The correct bolt has a shoulder on it which probably seats on the cylinder head and therefore prevents you from damaging the rocker cover by overtightening. The shoulder will also cause a weak spot and allow the bolt to shear if overtightened (as probably happened for you).
A previous owner had used a "gasket in a tube" to seal the old rubber gaskets. It worked in that it sealed the joint, but it makes a bluddy mess.
For the sake of £10, I'd recommend a new gasket

Success job done, used a 6 mm bolt shorter than org, large washer and a silcone gasket sealant, works a treat and no mess what ever, Would still like the org bolt so I don't get over tighten the new bolt.
;D ;D ;D

Great news for a temporary fix
Let's hope it stops the seepage, at least until a new gasket and a new rocker cover bolt

Thank you kind sir, Thats a few beer tokens I owe you. No problems! Sorry, I missed first class collection today so you should hopefully receive it on Monday I also took your advice and brought meself a set of tap and die, also a didgi caliper, saved me so pocket money as I have been worrieing about me brake disc, but well within limits both front and back. Also checked me tyers with it and plenty of wear yet in them. Good chap! Quality should be fine for home use; at those prices if they only do one job then fail you haven't lost any money. The disks may wear with a bit of a lip around the outer edge. If this happens, you will be measuring the thickness of the lip, not the disk. It took me a while but I did find Buzzin's (aka Buzzin) post showing his modification to turn his vernier into a micrometer www.ntvhonda.proboards.com/index.cgi?action=display&board=general&thread=485&page=1tape on your bits (no - your screwdriver bits ;D), switch on and touch the ends together then zero the gauge. Measure your disk thickness using the ends of the bits. |

Excellent - I'm pleased you got it OK
Apologies I didn't write a personal note but I knew you would know where it was from
I'm frequently told that my reward will be in heaven

Excellent post, top work all round, boys  Well done sky for turning a potential problem into a text book "How to recover from a snapped bolt situation"... ;D And McF, what a wonderful and useful response to a member in dire need.....  is it a bird, is it a plane, no its superMac. Just goes to show why you'd be an idiot not to join the forum if you got an NTV. You don't get that kind of service anywhere else on the web..  |
