Hey Buddy, please help me out with this one. I have a 1997 Ford F150 with the 4.2L. The engine in the vehicle is engine number two. Engine number one died when I attempted to compress the H2O in cylinder number one. The present engine also succumbed to the problem with cylinder one taking on water but I caught it before it was anything other than a rebuild. Here is the present problem, and, your thoughts would be appreciated. I have not yet put the vehicle on a rack yet---I will do that this Sunday---just asking what your thoughts may be. So, here is the deal, it starts and runs but dumps GALLONS OF water OUT THE BACK OF THE ENGINE. I have not seen from where it is pouring out yet. I will put it on a rack and test it Sunday. I was just hoping that you may have something Good to tell me like it is probably not a cracked block. Thanks for any insight you may afford me. t
