jayblack-gti 0 Posted October 28, 2006 Basicly a few weeks ago my cambelt snapped and upon removing the head id bent atleast 4 of the valves because there was no compression in either cylinder when i checked. so after buying another head from ebay for 16 quid, ive now had the head skimmed, done the valve stem seals and put the head back on the car. Now heres the gutting part, theres a spacer that is used for the head bolt which is nearest the cam pulley and at the back of the head, i remembered to put this in but forgot there was another thick washer thing that is used like with the other 9 head bolts, so tighten everything down, then hear water gushing out so basicly ive put a small whole through the block where the water pump is. shown in the pic below, i put the head bolt back in with the correct thick and thin spacers to show roughly how big the whole is Can this little whole be filled up with any type of metal filler sealant because i really dont want to have to replace the whole block, i might just MI it if it cant be fixed Share this post Link to post Share on other sites
Jonmurgie 2 Posted October 28, 2006 Oh man that's a killer... talk about a DOH! moment! I guess you can try that magic metal stuff, though I've no personal experience of it on a block before so will see what others say... Share this post Link to post Share on other sites
205007 12 Posted October 28, 2006 ive used the araldite stuff before for a cracked housing from exactly the same issue, car dir ove 2000 miles before the guy sold it without issue best excuse for an mi ive seen though! Share this post Link to post Share on other sites
jayblack-gti 0 Posted October 28, 2006 yeah a DOH moment lol, I presume there is an epoxy adhesive out there that will set solid but just worried about the amount of pressure that the water puts on the block, i was thinking about just filling the whole of that area flush because im not going to remove the head bolts for a long time and im waiting for an insurance pay out so might break the car in the next 6-8 months anyways. jay Share this post Link to post Share on other sites

welshpug 1,657 Posted October 28, 2006 IIRC the cooling system runs at 1bar max does it not? 14psi is sod all so some kind of heat resistant adhesive might work, or get someone to bung some weld on it?? Share this post Link to post Share on other sites
futura 3 Posted October 28, 2006 I would second the welding option if it's not too hard to get to. (but it does not look like it from the pic) Share this post Link to post Share on other sites
Bally 4 Posted October 29, 2006 take out the bolt, clean the area with carb cleaner, rough it up and use metal epoxy. Will last till the engine/car dies Share this post Link to post Share on other sites
Edp 67 3 Cars Posted October 29, 2006 My mate did the exact same thing on an old GTi. We used chemical metal to plug the hole and it was good for about 10k before he sold it. Worth a try IMO. Share this post Link to post Share on other sites
jayblack-gti 0 Posted October 29, 2006 Think ive sorted the problem with the help of some metal epoxy stuff, took the water pump out to check the whole and the chunk of metal that ive pushed through was sitting in the water pump housing, its only about the size of a penny so ive bonded it back in and covered it all over with the metal epoxy stuff, everythings all back together now and looking very new lol, just gonna give it till tomorrow to set properly before i fill the engine with coolant, turned engine over for a few seconds to get fuel through and check oil pressure, all ok, fingers crossed it holds, but should do, that stuff sets rock hard Jay Share this post Link to post Share on other sites
Anthony 1,003 Posted October 30, 2006 I've "fixed" an engine that someone did exactly this to using chemical metal, and it was fine for thousands of miles until he sold the car - you've nothing to lose by trying, put it that way Share this post Link to post Share on other sites
jayblack-gti 0 Posted October 31, 2006 Cars running fine now, no leaks or anythin, feels so good to be driving her again after pottering about in my sis mk3 astra for 2 weeks, thought my car felt tired but her astra is a boat. jay Share this post Link to post Share on other sites
