thanks, the coolant leak was internal, near cyl 4, gasket done. the fuel and oil consumtion, not leaking externally, is still there. each cyl is 180-200 on comp check. timing was done several times, before and after new chain. Coolant temp sensor new as well. when I checked injectors for resistance they showed .001 in all. seems low spec calls for 13.0-15.0. not to sure if thats the problem. Orif cold start temp sensor is prob. lots of blue smoke on start up and runs terrible after its warm. thanks guys, this is one of the better forums i,ve been too. take care and stay muddy.
