rayman Posted June 17, 2011 Share Posted June 17, 2011 Just put a new head gasket on after a rebuild and found when i put water in it that it leaked from either side down the length of the gasket.It was perfect before i took it off so can only presume dodgy gasket?.Any other ideas Quote Link to comment Share on other sites More sharing options...
dog321fish Posted June 18, 2011 Share Posted June 18, 2011 Did you use the 5 stage method for bolting the head back on? K-Seal maybe? Quote Link to comment Share on other sites More sharing options...
opel2000 Posted June 18, 2011 Share Posted June 18, 2011 Personally I would never assume "Dodgy Gasket" It is going to be something you have done. I would hazard a guess at some sort of particle or bit of something that has got in when positioning the head, or gasket moving when positioning the head that has gave you an uneven mating surface.

manta400john Posted June 18, 2011 Share Posted June 18, 2011 Maybe the bolts have bottomed out and so they might seem tight but the head isn't tight to the block ??? Just a thought. Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted June 18, 2011 Share Posted June 18, 2011 ive had this a couple of times. if you use a good quality gasket it will have a` built in`raised silicone strip around the edge & around the water ports.some cheaper gaskets dont have this & you need to add your own. theoretically if your head & face of block are PERFECTLY flat then it shouldnt be needed at all but whoever makes the better gaskets(gm,payen & fai i seem to think)abviously think you do. i replaced a 2 litre gasket a while back & it poured out of the side all along under the manifolds.took it all apart again & used a proper gasket with the silicone lines & all was well. (in worst case scenario obviously people have heads skimmed to true them up but its more awkward to have a block skim if needed) Quote Link to comment Share on other sites More sharing options...

dog321fish Posted June 19, 2011 Share Posted June 19, 2011 Are T-MIC head gaskets any good? Which are considered the best? Quote Link to comment Share on other sites More sharing options...
rayman Posted June 19, 2011 Author Share Posted June 19, 2011 Well it turns out that it was a dodgy gasket as i stripped it down found the o-ring thingy was in ,the bolts got checked with a gauge and there was nearly 10mm clearance to bottom.All i can say is avoid BGM gaskets .Thanks everyone for all your ideas and advise Quote Link to comment Share on other sites More sharing options...
lamchop77 Posted June 20, 2011 Share Posted June 20, 2011 Are T-MIC head gaskets any good? Which are considered the best? Payen gaskets are good, elring are better and can also be used with 96mm pistons. Best of all are cometic but they are about 140 quid so they should be!!!!
