Kato 0 Posted July 9, 2005 Report Share Posted July 9, 2005 Checking and adjusting the valve clearances is detailed (with diagrams) in the Service Manual in Section EB. The clearances should be checked when the Engine is cold. Clearances should be :- Inlet Valves 0.13 - 0.18mm (0.005 - 0.007 in) Exhaust valves 0.25 - 0.31mm (0.010 - 0.012 in) If you needs to adjust valve clearances he will need new shims and reset the belt tension to 95 Burroughs units on the Lotus / Burroughs Gauge (also detailed in the Lotus Service notes. You will also need the proper adhesive for the cam housings if they need to come apart. I think you should invest in a copy of the Lotus Service Notes It would also be useful to carry out a compression test. Figures should be 9.5 bar (140 lb/in2) minimum It is also important that he is using a good quality synthetic oil in the engine (Castrol RS 10W60 / Mobil 1 5W50 or 15W50) kato Lotus Esprit World Quote kato http://www.lotusespritworld.com' target='_blank'> Link to post Share on other sites
