Pete Lewis Posted August 30, 2022 Report Share Posted August 30, 2022 yes only the nuts studs is triumph only eg 1600 Engine : Canley Classics tip using the washer faced nuts will put the nut a little further down the stud so clean threads are very important if you want to stick to originals canley sell heavy duty washers and nuts ( toughend nuts are a black oiled finish ) anything shiny will likely strip a std bolt of 3/8unf takes 31lbft at a max so thay why the heads nuts are not ...normal ones Pete Link to comment Share on other sites More sharing options...

Pete Lewis Posted August 30, 2022 Report Share Posted August 30, 2022 the fire rings in the gasket have not made the same contact between 2 and 3 compared with elswhere what the gasket looking like ???? with rag down the cam follower gallery and in the bores the steel needs a good shine up with some not too coarse wet and dry to remove all the black deposits back to shiney may need the studs out to make a good job agree that stud is finished , they can be costly just replace any more like that one and you should be ok you should find the block end of the stud has a linear groove up the thread this is to allow any trapped oil out as fitting studs if the hole is part filled can explode the block face so the small groove is essential Pete 1 Link to comment Share on other sites More sharing options...
Paula Posted August 30, 2022 Author Report Share Posted August 30, 2022 The gasket looks good to me. I haven't cleaned it up yet but i can't see a definite fault. Is this the stud? https://www.jamespaddock.co.uk/head-stud-long-16002-liter-mk1-3 Link to comment Share on other sites More sharing options...

johny Posted August 30, 2022 Report Share Posted August 30, 2022 Although I cant find anything in the WSM is it worth checking the head with a straight edge and feelers? Plus while the heads off are you going to do anything with the valves? Then of course youre also in an ideal situation to check TDC of number 1 piston compared to the pulley mark👍 1 Link to comment Share on other sites More sharing options...
Colin Lindsay Posted August 30, 2022 Report Share Posted August 30, 2022 Waterways are badly choked with sediment, too - the ones to the right of No 1 and No 5 look bad. 1 Link to comment Share on other sites More sharing options...
Paula Posted August 30, 2022 Author Report Share Posted August 30, 2022 I wasn’t planning on doing anything apart from cleaning it up and a new gasket. Can anything be done about the waterways? oh the thermostat didn’t have a hole or pin in it Link to comment Share on other sites More sharing options...

johny Posted August 30, 2022 Report Share Posted August 30, 2022 You could mechanically clean the waterway holes as much as possible now and then do a soda clean as recommended on here once all back together.... 1 Link to comment Share on other sites More sharing options...

Make sure you flush any debris out when the system is reassembled. 1 Link to comment Share on other sites More sharing options...
johny Posted August 30, 2022 Report Share Posted August 30, 2022 Ive read Paula that over torqued head bolts can pull up the metal surrounding their holes in the block. I find it hard to believe the resulting 'pimple' could stop the head going down flat on the block but it might be something worth checking. The recommendation is to run a larger drill in the holes to slightly countersink them to remove this possibility... 1 Link to comment Share on other sites More sharing options...

Pete Lewis Posted August 30, 2022 Report Share Posted August 30, 2022 well the easy job is add a 3mm drilled hole in the stat rim. if you remove the studs and use a hard block to sand the face clean you will soon see if any hole has a raised periphery it will shine up before the main face things like a step drill/cone cutter are good for adding a shallow countersink to an exitisting hole and lots of other odd jobs 3PCS Step Drill Bit Set High Speed Steel Titanium Coated Cone Drill Bits Hole Cutter Power Tools for DIY Plastic Wood Metal : Amazon.co.uk: DIY & Tools Link to comment Share on other sites More sharing options...
