I brought the head off my Galant VR-4 to a fairly reputable machine shop in Coatesvile, PA. Spyder Custom Machining. After getting the head fuly ported, intake & exhaust manifolds port-matched, bronze valve guides, 3g lifters, ferrea valve seals... the good stuff... Upon getting my head back and re-installed, my motor was throwing a knock DTC as well as villantly shaking. Compression test reads as follows 4-162, 3-158, 2-164, 1<20psi. WTF, Maybe it is the new BC 272 cams?!? So I leaked it down and air is comming out the exhaust. (thank you Jesse RVLUTION) Tuesday I gave the owner of the shop my head and explained the problem. lastnight (thurs) got the head back, "repaired" and threw it on the car. No cams no rockers installed and still the leaking to the exhaust. So now I'm about to remove and re-install the head for a 3rd time. The only thing in my mind is that the valve seat had a run in w/ the porting bit...
SO don't go to SPYDER PREP Custom Machine and Racing Heads @ 180 Loomis Ave, Coatesville PA 19320
This is a #'s matching head to a limited production Mitsu Galant VR-4 #1012-2000
