One new std piston?

[Edd Wrath]

I've made an error--I re-assembled my 5L without closely checking the piston clearances, and I now find No#4 cylinder firing intermittently and with huge blowby, and a loud cam speed knock from back of block.   Suspect piston clearance too great.    Unwilling to pull down until I can source a single new piston -- proving very difficult, anyone got one lying about or knows source at reas price?   OEM NOT required.   Set not needed.

If you have a piston flopping around in there, there is a good chance that you will need other work carried out such as machining.
