SRF Posted March 23, 2015 Report Share Posted March 23, 2015 I have removed the head from my Bond Equipe GT4s. The cylinder pressures were well down. The PO supposedly had done a head job, the engine had not run since. It was a poor job with the mating surfaces of head and block not cleaned properly and a fluid test showed leaks from all combustion chambers. The head had indentations where the recessed gasket had dug in slightly. I have had a quote for fitting new hardened exhaust valve seats and a head skim of £200 ish. So I am going to have it done, I am also going to fit new exhaust valves. Is it worth replacing the inlet valves? The guides are excellent so I am not going to fit valve stem seals.

Darren Groves Posted March 23, 2015 Report Share Posted March 23, 2015 Is there anything wrong with the valves that they need replacing? You could have them re-cut if you're worried, it will be cheaper than buying new and just as effecting providing they are not too far gone.

Pete Lewis Posted March 24, 2015 Report Share Posted March 24, 2015 None of the Inlets are required to be anything lead free only the exhausts, most sold are lead free compatible eg rimmer,, canley etc. pete Link to comment Share on other sites More sharing options...
