Any experience with 1/2-20 TIMESERT oil pan plug thread repair?
or know anyone who does?
They have note on their website to use the ones for cast aluminum pans on a sheet metal pan where an oversized thread has been used.
I sent them an e-mail asking what the working range was for the insert, and they wrote back
"The 1/2-20 drain plug kit includes inserts of .400 length, your drain
pan thickness should be at least .400 thick."
I don't know of any sheet metal pans that are at least .4" thick - except may be early ones with a nut elded to the inside?
