4.6 on fire - is it still good?

[skippy3k]

I've got a line on a 4.6 engine for a good deal, but it was involved in a fire. As you can see the photo doesn't show serious meltage, but I am wondering if I am crazy to even consider it. It just looks dirty to me. I'm pretty much just after the block...I don't care about the wiring. So my questions;

1. Would you buy an engine involved in a fire?
2. Seeing that the plenum is missing with the all important "4.6" designation, how can I visually identify that the engine is a 4.6?

By what year vehicle it came out of for one

oil fill looks to be on the opposite side

It came out of a 1996 P38, which had both GEMS 4.0 and 4.6. Regardless, I don't even know if the engine that we are looking is the original...it may have been swapped out, therefore I don't want to base it on the model of vehicle.

Look for a Label

I work at a diesel engine factory, and I would be more then surprised if the block did not have a part number on it somewhere, probably stamped or cast into it. Id look for that, otherwise was the 4.6 bored out in diameter or stroked out vs the 4.0, could measure.

As far as fire goes, it would have to be very hot for very long to damage the block in my opinion.

Good luck.

When you talk to Daren, ask him about his 4.6 swap. He put a shitload of mods on it too!

If the fire was not hot enough to melt all the wires and hoses, surely it was not hot enough to hurt that block.

to be 100% sure, drop the pan and look for the 4.6 cast into the counterweights on the crank.

I would have no issues buying that engine EXCEPT if it looked like the oil lines were the cause of the fire.

Oil lines go could mean low pressure. However, even still, I would probably buy it if the price were right.

PS I would certainly do a valve job and reseal on it as a matter of course.

Who's Daren?

Aha, that's what I was looking for, thanks. Of course, not having to remove something to tell if it's a 4.6 would be better, but if this is the only way, I'll do it.

Fucking oil lines scare the shit out of me. I had my shop guys make new lines for ALL of my Rovers. I can't even believe how many times I've read about fires and stuff caused by this stupid design Rover put on all of their vehicles.

What's your intent with this motor. Besides the fire, it looks like the internal has been subjected to the elements. Besides the plenum being off, the oil cap is missing. When Isay open to the elements, I don't mean left out in he rain. With those two components missing, it's a lot easier for humidity to get into the engine.

If your plan is to bolt this engine right in, then there ar certain precautions I would do. If you're planning on taking apart the engine, then I wouldn't be two worried about it.

Another suggeston on figuring out if it's a 4.0 or 4.6, ask the seller to take a pic of the egine serial number.

I would rebuild the engine from scratch. It will hopefully be my winter project.
