frodo_monkey 0 Posted August 8, 2006 Hi all, Have spent an enjoyable afternoon dismembering my new project engine (thanks Dodsworth_GTi!) and have got stuck... The last head bolt just won't shift! I've tried the torque wrench, the breaker bar and the air gun, and am unwilling to do much more in case I bugger the Torx-bit of the bolt (looking a bit ropey already). The engine is just sat on a concrete floor, so I haven't got a car to 'pull' against. I reckon dosing it in WD40 and hammering in a '60' Torx socket, then trying the breaker bar again - but does anybody have any better suggestions? Ta, Frodo Share this post Link to post Share on other sites

Ta, Frodo Put the other bolts back in and torque them up. That'll take the load off the stuck one. If possible give the bolt head a good whack with a copper or bronze drift to shock it loose first. There is a section of my website devoted to removing recalcitrant fasteners. Share this post Link to post Share on other sites
GLPoomobile 958 Posted August 9, 2006 Are you in a hurry to get it done? I was paranoid about snapping a head bolt so soaked all of mine in Plusgas for about 4 days in a row. On the second day I carefully shocked the bolts loose a wee bit and soaked them up. On the third day I loosened them a bit more and soaked again. They all came out a treat in the end, but maybe I'd have had no issues if I had just not bothered with all that kerfuffle! Who knows? Share this post Link to post Share on other sites

sorr 0 Posted August 10, 2006 I get the stubborn ones out using a two man approach. As said breviously put the other bolts back in a torque them up to level everything out. Get the breaker bar on the stubborn bolt and get as much load as you can on it. Then get a friend to hit the top of the breaker bar with a large hammer while you still have the load on the bolt. An I mean hit not tap....I would use a bit of wood between the breaker bar and hammer so no damage will be done if it slips. Share this post Link to post Share on other sites
