Re: Low Oil Pressure - but only when warmed up?

Oh for the Quote:I do burn some oil, but not much, and there are some very slow leaks coming from god-knows-where. to bad you did not check heads the most likely change the valve hats O-ring seals mostly there a little wear out heat age It easier to do with head of but can be done head on just do not drop a vale. If still burning oil the heads bronze valve guides done at a shop, or the rings wear a bit.
