Ecosse Posted February 29 Report Share Posted February 29 Hello All, It would appear that there are two torque settings for the cylinder head bolts quoted, could anyone advise as to which figure should be used. Thanks, Cliff Quote Link to post Share on other sites
jerrytr5 Posted March 2 Report Share Posted March 2 My BL TR7 manual quotes 50 lbft. My BL Sprint manual quotes 55 ibft. I have seen 58 & 60 quoted. The TR7 & Sprint manuals differ in tightening sequence, however I would suggest tighten incrementally from the middle working out starting with the nuts then bolts. eg: Nuts 20, bolts 20, then nuts 40, bolts 40 etc. I use 60 lbft on my Sprint engine. Run to operating temp & leave to cool. Re-torque. Repeat after 1 hour at operating temp. Repeat after 250 miles & 1000 miles, then every 3000 miles. Jerry Quote Link to post Share on other sites
