I pulled the plugs on my j-spec (s5) and they were covered in rust!!! I looked in the motor and it had surface rust and what not on the rotors. It was locked up.. I then proceeded to pump some MMO into the spark plug holes and rotated the motor loose. It came loose very easily. Rusty water then poored out of the spark plug holes. I had very strong compression bursts from each port so it appears that the seals (apex) are good.

My question is will the Car still run with the motor like this? I sprayed some PB in there and rotated it until the fluid came out clear again. I know I should probably just rebuild it but It has to be at least IN the car for my brother-in-law's senior project that is due this month. A rebuild will be in the near future but I wonder will it run at all?

Thanks

 

Start It!! I Dare You!!

 

Oh I am going to try to start it. LOL.. But I wonder how hard the car will be to start PLUS the turbo is in great shape and I would hate to F that thing up with little rusty particles...lol.. Maybe i will slap an old s4 turbo on there while I try to start it up..

 

PB it couple more times, new oil/filer, run the bitch for a couple of hours, change the oil again
or
fill the engine with MMO and let it sit for a week, drain it, oil change, and I bet it'll run fine

 

It is pickled in MMo as we speak.. Oil change will come shorly after the wiring is done.. Thanks so much. It appears it was stored outside and water came in throuh the intake.. Because it wasn't coolant and the rust was only on one of the faces of the rotors...

 

It's been my experience that rotaries are robust little engines despite what the media would have you believe. The FD I bought literally sat for 3 years before I got my hands on it - all it needed to run was a new battery and som TLC to run well. People in general are stupid especially when it comes to cars and 7's just don't like stupid people.

 

my jspec s4 was like that. The front rotor had no compression, so I never got to start it.

 

You should listen to this guy, he a descendant from Einstein himself......

I would not put that engine in unless you rebuild it. Chances are that the first time you go to crank it the housings are going to get pitted to no return. just my opinion

 

Start it -Start it - Start it : LOL :
Keep us updated.

 

if u got rot on the inside your seals are gone

>>J-Rat- start It!! I Dare You!! -- i tripel dog dare you

 

just start it already...if it blows up...then there nothing you could have done about it but rebuild it...if it runs...you got lucky...GO FOR IT...TAKE A VIDEO SO WE CAN ALL SEE IT BLOW UP!

 

One thing.

Some Jspec importers pressure wash the engines to clean them.

This could be the reason why you had water in there.

Then there's the more common problem of bad engine.

 

I hope it works out, my brother in law is only 17 and has put virtually every dime he has into this car.. Here are his mods..

Rusty S5 j-spec
Racing Beat Springs and Sway Bars
Hks Intake
Hks BOV
Racing Beat Downpipe
K&N Filter
S4 wiring harness and S5 injectors wired in
S5 T2 wheels
Custom exhaust w/ Fart cans.

Hope all goes well.. If not another $600-$800 for a local rebuild....

 

plus whatever is bad internally. That would be my only scare is that something else would mess up to where I would have to replace it (ie irons, housings etc...) I thought if the iron face was rusted the iron was bad? How can you tell if there is rust on the iron?

 

Did I miss anything?
I didn't know it takes that long to start a car

How did it go man? You have many audience waiting .......

 

you can't cause any more damage than is already done, install it and see what happens.
