catalytic converters
Hello everyone.
I have an "87 XJS that is down on power. I replaced the starter yesterday due to a bad solenoid and had to remove the starboard Cat assembly. It appears plugged up and since the car has 90K miles I suppose the other side is too. If I remove them and ream them out would the reduced back-pressure effect the timing? These are the units that are attached to the manifolds, not the ones just downstream.
Thanks,
Pete Carr

I gutted the cats on my 90 xj6, had no problems. If there is blockage the heat caused by the blockage will cause blown head gasket and or warped head(i know as my xj had plogged cats and thus the gasket problems)
