Do bad valve guides equal lost power?
My car was burning oil in a couple cylinders. I puled the valve springs to replace the valve seals and found a couple valves that wiggle side to side in the guide. I can also hear my compressed air escaping past them.
Whats weird is that all the cylinders came up with the same 160 lb compression number. My car also dynoed 270 hp @ 5000 rpm on a Mustang chassis dyno. I think the rpm peak is a few hundred rpm low for a ported TFS/GT-40/E-cammed car. Perhaps these leaky valves have something to do with that? Any ideas?.......... |
