Changed the rocker cover gasket yesterday and when i was bolting it back together one of the rocker bolts screwed in and kept turning

What can i do to fix the stripped hole

essexrsturbo

ive seen that bolt strip out a few times on rst's... your av to re tap it very carfully..

cossiemen

yep as essexrsturbo said; you have to re tap it very carefully.
if the bolt doesn't come out you have too drill it out very carefully

The bolt is out, just need to sort out the stripped hole, can it be tapped on the car or does the head need to come off

you can tap it out which means you will need a bigger bolt, or you can fill it with that liquid metal, let it go off then drill and tap it the same size as it should be.
im a engineer and have done this many times to holes on all sorts,but make sure the hole is clean, bit of degreaser will do it, dont have to drill it out before as the rought surface will help it bond to it.

essexrsturbo

head can stay on mate, just take the rocker cover off, clean the shit from near the hole and get your self a cutting tap thing (dnt no wot there called.lol) and gently tap it out while spraying it with a lubricant like wd40 or sumink..

look dont mean to put anyone down here, but you cant just retap it, the thread has been stripped out, you cant put a 6mm tap in if the hole is now 7mm can ya, you will have to tap it out bigger, this means that one of your bolts will have to be bigger. unless you re-fill the hole and start again.
easy way to do it, take the rocker box off (make sure you dont get the swarf in the head so cover it) if your re-taping, drill the right size hole for the tap then tap it, if your gunna fill it (best way) clean it, fill it, wait till it goes off, drill the hole (5mm) then re-tap it with the 6mm tap, take it slow, use lube, turn it clockwise then give it a little anit clock wise (1/4 turn) this is so the alloy dont glog up the tap.
take ya time and job done.
if you were near me i would do it for ya for free.

Thing is im in Glasgow

i aint coming up there from the isle of wight to do it lol.
na your be alright, take ya time and make sure when you re-tap it that you have the tap stright, and do take your time, tapping can be easy but if you rush and break the tap ya fucked cos you wont drill it out cos its hardend.
get the proper tool for the tap, dond use a spanner as you will never get it stright.
if you want more help dude PM me .
