Q re power steering fluid overheating


Recommended Posts

The power steering fluid in my 3.4L 996 sometimes overheats resulting in some spewing out the air purge value. The purge valve "cap" isn't secured very tight, and the pressure pushes it up, or sometimes off completely.

Any thoughts on the reason for this? [do the power steering lines need to be insulated/isolated?]

Any thoughts on how to fix/rig this? I've been adhering to the "put some more in" school for now. But I'd like to identify if there is a problem and how it can be fixed. FWIW, this is a crate 3.4 engine installed this year, now with around 8,000 miles on it.
