turbo Grant Posted November 14, 2014 Share Posted November 14, 2014 Heli-coil and you will be stronger than standard Quote Link to post Share on other sites
mikey4410 Posted November 14, 2014 Share Posted November 14, 2014 yeah the threads are part of an alloy head and very soft. Quote Link to post Share on other sites
rwdrev Posted November 14, 2014 Author Share Posted November 14, 2014 can this be done without taking the head off, really cant be arsed taking the head off it and stripping just to sort this fuckup i have done Quote Link to post Share on other sites
5e colin Posted November 14, 2014 Share Posted November 14, 2014 can be done in situ but be very carefull with the metal splinters when drilling as u know urselve they will destroy your engine is the fal in Quote Link to post Share on other sites
rwdrev Posted November 14, 2014 Author Share Posted November 14, 2014 can be done in situ but be very carefull with the metal splinters when drilling as u know urselve they will destroy your engine is the fal in thats the bit that conserns me. fuuuuuuuuuuuuuuuuckkkkkkkkkk..... really cant be arsed taking it off, but looks like i am gonna have to. think its gonna be sold soon, getting fed up of always fixing it. had it about 4 years and its spent 3/4 of that time blown up or broke.....

yaristurbo Posted November 15, 2014 Share Posted November 15, 2014 If you don't take it off mask up well and cover everything try dipping the drill bit in grease to collect the filings Quote Link to post Share on other sites
turbo Grant Posted November 15, 2014 Share Posted November 15, 2014 Careful preparation to the area and you won't get a single bit of swarf in the engine. Taking the head of sounds a bit extream just to sort one bolt out. Quote Link to post Share on other sites
rwdrev Posted November 15, 2014 Author Share Posted November 15, 2014 il see what i can come up with. will have to got to the engineering shop for a helicoil. think il just go for the mask it to death and be very careful. it does sound extreme, but its half stripped anyway, so wouldnt be a biggy to whip it off.

mikey4410 Posted November 15, 2014 Share Posted November 15, 2014 as above.masking of area is the obvious way to go.i would never take a head off for a petty job such as thatmakes me laugh as I didnt even take my head of for valve stem seals.lol.thats not an option.heads off are a no-no. haha Quote Link to post Share on other sites
rwdrev Posted November 15, 2014 Author Share Posted November 15, 2014 does anyone know the thread size and pitch for these bolts? see if i can order some Quote Link to post Share on other sites
fiddlersport Posted November 15, 2014 Share Posted November 15, 2014 get a specialist out to do it for you ? Quote Link to post Share on other sites
rwdrev Posted November 16, 2014 Author Share Posted November 16, 2014 only people close by will need the head on there bench. so that means it will be off for weeks (there not the quickest) Quote Link to post Share on other sites
fiddlersport Posted November 16, 2014 Share Posted November 16, 2014 we have a guy in manchester who is mobile, mr threads his company name is or something like that !! Quote Link to post Share on other sites
rwdrev Posted November 16, 2014 Author Share Posted November 16, 2014 the joy of living down south. got nothing up here, not close by or mobile. have 1 machine shop and 1 reconditioner/small machine shop. the machine shop needs the head on the bench, and the other place would do it in the car, but cant get the car to the shop as my landy is now off the road, and the golf wont pull the transporter.

fiddlersport Posted November 18, 2014 Share Posted November 18, 2014 put up a pic dude ! if you have the right tools it can be done DIY or if you not that confident then off to the machine shop ! Quote Link to post Share on other sites
rwdrev Posted November 18, 2014 Author Share Posted November 18, 2014 its not a good bit to take a pic of. its the front right hand rocker /cam cap bolt. might just change the head over. i got a couple more that can go on, or finish port and polishing the head i have started and get it rebuilt and slapped on. i dont have the heli kit, but would be confident enough to do the job. still needing to find out the thread pitch and size, as i dont have a thread gauge Quote Link to post Share on other sites
fiddlersport Posted November 18, 2014 Share Posted November 18, 2014 guessing you have fastened the head down to the block ? be patient and take it to the guy who said he can do it on the car ! i have done a few head bolts tht have been stripped before, this is just a cam/cap carrier so once it is repaired it should be fine !

rwdrev Posted December 1, 2014 Author Share Posted December 1, 2014 got this fixed. took the car upto the machine shop and they did it outside whilst still loaded on the trailer. picking it up tomoz night. i had removed the cams to nip up the head bolts as the gasket was weaping slightly and was just refitting them and , ping, it went. first time i have ever stripped a thread fitting the cams. been on and off enough times, lol. maybe that was a cause tho, not sure, but alls good now. hope to get it back together at weekend Quote Link to post Share on other sites
