So I narrowed my gas in my oil problem down to a bad injector. #4 would just turn on and not shut off when the pump was charged. So i broke it all down and have new injecors sitting ready to go on, but my question is this. Can I use the gasket I just put on the upper manifold again or so I have to replace it. Keep in mind this is a fresh rebuilt motor and the gasket has maybe 50-100 miles on it. Just trying to figure that out before I start putting her back together. Thanks.
