Thanks guys, I really appreciate the input, I have been wondering where to get the oil analysed for my yanmar diesel in my sailboat, might as well do them both. I probably should go ahead and find someone with the equip to do the leakdown test and if it's ok will go ahead with valve seals, I have searched on that and feel confident that task is within my abilities if I am carefull. I take no one is very worried about the valve clatter at this point?

you folks are great, maybe with your help I can give the neat little car anouther life!
