Guys, How many have had to TRY and fix a leaking thermostat housings on the 429/460 ? I found the root cause of my leak last night. The Chrome POS housings you get from Mr. Gasket/TransDAPT/SPECTRE/Ford Racing are all junk (same maker in CHINA). The flange warps after a only a few heat cycles. I am trying to find another supplier/design now. What have you all done to fix it, (besides using half a tube of Silicon
) which is only a temporary fix. I measured a total of 0.015 warpage , you can see daylight under the flange on a flat surface its so bad ! Educate me.
