mike, no idea bro... i hate those gremlins... as a tip, try cutting off that little flap thing on the thermostat, i've HEARD that by removing that, it can relieve pressure on the system...
in BZ news, i got the new tranny in today... and guys, you don't know how bad not having third gear is until you daily it w/out it for months.... now it's a beautiful, smooth shifting, and QUIET machine, the Tomei SS adds a quick enough shift to the new trans... goddamn it's so nice...
oh, and i mounted my S14 SE wheels... i thought it would be straight booboo status, but once cleaned up, i don't think it's all that bad, besides being pizza cutter sizes... then again, i've always been partial to the S14 SE on damn near any S chassis...
