Stuck Oil Pressure Relief Piston, small one.... Options

[Aaron Cox]

any ideas how to get this out?

Steve stromberg had a few good ideas: we tried cranking the motor with plugs out...and making the oil pressure push it out- No Go...
tried a magnet - No Go

i guess im down to an EZ out... (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif)

On T1 engines the inside of the piston is just a bit smaller than a 3/8" socket extension, so you can tap (lightly) the extension into the piston and then turn it. It's the turning that's the trick, breaking it loose from whatever's binding it. You can apply a lot more force turning than anything else you can do in that tight space. Once it turns it should come right out, usually still wedged onto the extension. If it doesn't then fill it with penetrating oil and turn it again so the pentrating oil can get around and up onto the top side and it should come free. I'm pretty sure the pistons are the same size in the T4, but not certain. If the socket extension doesn't fit then just find something else that will wedge into it.
