So I was driving last summer and when taking off from a red light, heard a huge bang (fuel line popped off as you'll see). Needless to say, by the time I could pull over and shut the car off, the damage was already done.
Since then I have been trying to decide to fix or sell. I took out most items under the hood to see how bad it really was. I need wiring harnesses, plastics, plenum, sensors etc... but not sure if the engine is still good.


Is there a way to test the engine while still under the hood and in this state? (I am mainly worried about the seals).
ECM looks untouched and the car looks great still... just this little issue.


Any advice or opinions are welcome. It has only 2 scratches on this thing so I would like to keep if it doesn't need everything (incl. engine) replaced.

i probably have a bunch of the stuff you need if you fix it but why not get insurance claim?

KOLTON

I already did that. It is settled and the car is now off the road and in the driveway.
Now it is time to fix... or sell. I am more looking for how I can test the engine to see if I can just start building the car back up a little at a time.
Do you think the engine would take internal damage from this? It did not burn long but took out quite a bit on top of the engine.

It is unlikely that the fire damaged the internals of the engine. Sitting around with the intake open has likely done more damage.

Put some ATF or oil into the intake and turn it over to coat the rotors and the internals to keep them from rusting

Looks like you need an engine harness and the intake and other bits...

If you are wondering about the engine you could get it compression tested....you might have to jump the starter to do it...

KOLTON

Thank you.
It has only been open for about a week now but I will get it covered and oil in it.


Do this by turning the eccentric shaft?


And yes, most if not all of this stuff I have removed is bolt on..
I'm not a mechanic.. but like learning.. is this something if I got the parts can potentially bolt back down and work?
How would I do a compression test with how it sits now?

I see that happened in Kenmore, are you looking to do the work yourself? Not too many rotary "specialists" around here... Even my buddy who's a mechanic won't touch my car, lol

yes turn the es after adding oil. iirc its 19mm bolt in the middle of the biggest most bottom pully

KOLTON

I would like to do it myself... I work in collision, but this is not my specialty. Thanks for the info on the pully 200.
Yea, I have had a couple mishaps trusting people who "have worked on one before". before this was the secondary shutter valve no one could figure out.
I guess the hardest part of this seems to be that connectors and that are melted. I can splice wiring fine, any ideas on the best way to land all of these parts? If the engine turns, I think I may start re-building.

KOLTON

I also am concerned about splicing SRS wiring in. I know from collision this is not the best idea... but has done before im sure.

In your case, it may be ideal to get one to part out, CL only has one that may be a good candidate in Syracuse for 2k, might be worth a look. Other than that, maybe the part outs in the FS might have the parts you need since you might not need a rebuild. BTW, how many miles in that motor?

KOLTON

~84,000
FS?
I was saw the one in Cuse.. looks like it could work (***OBV. NEW FUEL LINES***)
Is it ok to splice the entire front wiring harness?? Or is going through the firewall and taking the dash out my only option?
The engine harness will be plug and play I assume if I can get an uncut one.. at least once the smaller bolt on parts are changed out.

i have ecu, throttle body, maybe umi, abs system/box whatever its called and might be able to help with a harness

KOLTON

As small as the fire was (in relation to some ive seen on here), I need a ton of small, probably hard to find parts.- a parts car may be the way to go...
Does anyone have links to detailed diagrams for under the hood? hopefully w/ part numbers? lol

boricua13

What year is yours? I have access to Alldata, so I might get the # you need

KOLTON

I have Alldata, ill check that out but I want a diagram because some items were burnt so bad that it just had to be chisled off or were unrecognizable.
It is a 2005 Manual GT.

Just get a used engine harness. That will fix 90% of the issues you have with wiring. Likely the MAF harness you will have to fix as it comes off the front harness

Otherwise it will mostly be cleaning stuff up and replacing it.

I would replace the fuel rails and the injectors as well when you are at it. Hopefully you can find someone parting out the whole car and get all of it at once

boricua13

You should be able to get all the diagrams under diag & repair, left side, diagrams. You can also get the connector views with pin-outs.

KOLTON

thanks everyone.
I will get some of this started and post more pics// issues as they come up.
This is the first time I have dug into an engine bay so i'm sure ill have some questions...


anything else I should pay attention to, or watch out for that you can think looking at the photos?

KOLTON

what way do I try to turn the eccentric shaft?

Reoze

Personally, I'd buy one with a blown engine, swap them out, and part out the old car. My biggest concern wouldn't be the physical damage from the fire as much as the potential for the fried harness to have shorted out other electronics.

At least with a blown engine you more or less know what you're getting yourself in to. This is a bit of a mystery box.

KOLTON

Use the one with a blown engine you mean? Swap my engine into it and part out my current 8?
They are hard to find up here without being rotted underneath. I don't know how people drive these during buffalo winters but either that or they are not stored and driven when there is still salt on the roads.
Plus, I don't have the equipment to pull engines where as these bolt on parts are easy to install and a way for me to learn a little about the mechanics of how it all works. not too sure how much an engine swap is for this car, but I would assume buying a blown 8 and then paying for that is probably more money than buying hoses and used harnesses, no?

Reoze

That's exactly what I was suggesting. While pulling the engine might sound like a pretty big task, I honestly think the whole process would go much quicker than debugging wiring issues and resoldering melted connectors. With a bonus being that you end up with a spare block you can rebuild if you want.

As you said, a lot of these parts might be hard to find individually. While your short block is probably completely fine, anything attached to the intake manifold is complete toast. And anything directly connected to these items electrically are suspect at this point too.

Whether you decide to go that route, or fix the one you have, you'll most likely need a parts car. I'd personally opt to fix the one with a single issue (bad engine) rather than replace a dozen and a half parts to find out the rabbit hole keeps getting deeper.

Also, while some think your engine internals are completely fine. I would be slightly worried about melted plastic that might have dripped into the intake manifold. I'd probably be looking to pull the engine either way just to inspect the potential damage.
