Harbor Freight 21 Gallon (red) Broke on Ring
by Neil Cunningham
I have a HF 21 Gallon 3HP the older RED model. It blew a head gasket and in trying to repair it with gasket material from Auto Zone the Piston came out of the head.
In trying to put it back in I broke the top ring (top of the piston) =.
I went ahead and replaced all 3 gaskets (I made them from sheet of gasket material) I reassembled the unit and it wont build pressure.
I have air coming out of the intake.
So my questions are these, would this broken ring keep this from building pressure, like is air leaking by the piston etc? If I by the rebuild kit others have talked about will that probably fix this....
