Steiger325 Posted June 29, 2015 Share Posted June 29, 2015 Good Evening I am hoping to catch an owner who may have suffered a similar fate. Have a '27 Lincoln L 357 cube motor. Motor runs fine but when revved it pressurises coolant. First idea that springs to mind is a head gasket ( or 2 ! ), but looking at the inlet / water / exhaust manifold ( its running original updraft carb ) it would appear that corrosion inside it could cause pressure from exhaust to get into water jacket and top hose . or am I just lacking in knowledge of this engine setup ! I have not removed any parts yet but was thinking of pulling and inspecting manifold before lashing out dollars on head gaskets. Any learned ideas would be greatly appreciated. Many Thanks Tim Link to comment Share on other sites More sharing options...
abelincoln Posted June 30, 2015 Share Posted June 30, 2015 Most auto parts stores will have a kit to check for exhaust gas in water. I got mine from NAPA. Do you see bubbles? Is there any water in the oil? Good Luck.Abe Link to comment Share on other sites More sharing options...
