Mitch-12 Posted June 10, 2011 Report Share Posted June 10, 2011 there is a copper bit that has to line up with a oil hole in the block Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted June 10, 2011 Report Share Posted June 10, 2011 Which bit couldn't you find Chansey? How to fit the gasket on the block, top or bottom, left or right, or how to do a whole 'change a headgasket' job? Quote Link to comment Share on other sites More sharing options...

scottiriver Posted June 11, 2011 Report Share Posted June 11, 2011 yeah just did mine cos it overheated, blew the gasket and warped the head :( then to top things off, the coolant went into the oil :( 1. remove inlet and exhaust manifolds, spark plugs, leads and dissy cap 2. remove two bolts and on the top of the rocker cover and remove rocker cover 3. remove rocker gear 4. in opposite, diagonal order, remove the cylinder head bolts 5. pull off cylinder head 6. remove and discard gasket and check block and cylinder head for warping 7. (optional) remove and regrind valves into seats 8. install cylinder head with bolts in opposite diagonal order to correct torque (if u can get the bolts in corrent order from a book then thats better 9. install rocker gear, 10. install rocker cover 11. install spark plugs, leads, dissy cap, and manifolds 12. run engine till operating temp and then adjust tappets thats the very basic process that i did and it worked a charm :) good luck Quote Link to comment Share on other sites More sharing options...

ChanseyKE55 Posted June 13, 2011 Author Report Share Posted June 13, 2011 Hey guys just wondering a)Torque settings for head bolts? b)Anyone un-common sized sockets ill need or uncommon tools? Quote Link to comment Share on other sites More sharing options...
ke70dave Posted June 13, 2011 Report Share Posted June 13, 2011 best bet is to grab yourself a gregories manual mate. all the torque settings will be in there. actually if i recall correctly, last time i bought a headgasket for a 4k (ACL i think) it came with the torque sequence and settings in the packet. i changed a 4k headgasket with a basic socket set, no weird sizes required.
