I found a 7 that had a fire under the hood. I'm wanting to use the short block. All the wires are melted, and the guy has no way to compression test it or anything. It's also 250 miles away. I was wondering if anyone had experience re-using a block after a fire. Could it get hot enough to damage the soft seals inside the engine? This one was rebuilt 40k miles ago, and should be in pretty good shape internally. If anyone has a blown engine that they want to sell the accessories (wiring, plastic parts, injectors etc...) from, I would be interested in that also. TIA fj

 

i bought a t2 engine that had burnt then sat out in a junkyard for years. the intake was still intact but all hoses and wires were burnt. i took it home stripped it to a short block put all my intake and fuel stuff on it and ran it for 5k (then sold it) until i finished my engine build. the engine didnt smoke or use water. the car also had ~100k or so on it.

When you say intake, I'm assuming you mean the metal parts? UIM/LIM? Thanks for your input.

 

was the whole engine blazed up? if you rebuild you would be fine. the iron is thick as hell. maybe the oil control seals might be FUBARed if the fire was directed there. Pics? honestly, though, i would rebuild for peace of mind. But im sure others with burnt motor experience can give you better advice.

 

The fire itself, or the heat from the fire, won't affect the internals in any way. After all...you have pockets of coolant between the internals and outside. Temps inside can see over 1000* F during combustion, yet the outside of the block gets no hotter than 250* because it's insulated by coolant...the same applies here, just reversed.

The problem is that the ones i've taken apart get all rusty inside. I suppose that some water or chemicals get into the intake and cause rust and corrosion inside. IT depends on how long it sat since the fire...more than 3 months and I would be cautious, more than 6 months and I would probably let it go.

 

I appreciate the respose Kevin. It's only $600 for the whole car, so I should be able to get quite a few parts from it. The FPD on mine started leaking last week, luckily it didn't burn down. I used the illustration on you website to help me fix it. The old bolt trick. Thanks
