Engine mount brackets thread casting broken

[Jason_B]

Well, imagine my luck...I replaced engine mounts today and found that one of the castings in the engine that the bolt goes into through the engine mounting bracket is busted out. The rear one on the left side. I have the other two torqued to 41 foot pounds but the rear bolt is just there. I think it was already broken as I could not see a piece laying anywhere and the metal where it appeared to have broken away from wasn't shiny like it was a fresh break. Does Ford make a repair plate for that?

Two will prob support it fine if its being doing it up to now, unless you plan on upgrading the engine to produce more torque. I wouldn't think there's any way to fix that other than a block replacement.

That's what I hope is that it will hold up with two. If any more of them break, talk about being in a world of hurt. I bought this one used from a person that gets cars from auction and fixes them up. I knew there would be some issues but was told at the time it was a clear title. Apparently one states definition of clear doesn't follow in another state.... reconstructed title is what I have now. Our state insisted it was collision damage but it turns out that it was in the auction lot for engine damage. The previous owner had run over something and busted the oil pan. I THINK but am not certain that the guy I bought it from put an engine and transmission from another mustang in this one, but it DOES have a new oil pan on it, so who knows if maybe the previous owner had already done an engine swap, and this guy did the pan. Anyhow, so I've been chasing squeals (water pump) and vibrations since I got it. It shudders and vibrates in reverse, and when turning to the left. The guy I bought it from said he thinks it may be engine mounts. I kept driving for a while until I was pretty confident it was actually the mounts before I changed them. Well now it feels like the vibration may be a little worse since changing mounts. I noticed something yesterday getting out of it while it was vibrating and still running. When I got out the noise changed. Bouncing on either side changes the vibration pitch and strength. Is that a subframe issue?
