Tore down my blown 13B today. We knew there was something messed with the front rotor. What we found was something........different from what we thought. Being both of us who took it apart being our first tear down, it was quite an adventure. Cause was it ran dry of oil under EXTREME LOAD.

Heres alot of pics detailing what we found. Let the Hilarity ensue. Remember, its the front rotor thats damaged. This motor had approximitly 40,000 or so kms.

Thanks to Nubian for providing a roof and a helping hand.

 

More.

 

Rear Rotor Time.

 

Rear Rotor and E-Shaft Pics.

 

did that seal melt istself.....omh thats bad

 

End Plate Damage.

 

Damn, I think you need a new motor.....

 

The bearing in the front broke free of the rotor and adhered itself to the e-shaft. We were looking for the bearing for the rotor and it was on the e-shaft. We easily removed it. The rotor itself 'walked' back and forth between irons and basically the corner seals and side seals are now permanently part of the rotor. Both Irons are done. Rotor housings may be good, Im going to check if they are in spec tomorrow. Same with the e-shaft. Other than some heat marks, it looks fine. Check that for spec. Both Stationary gears look un-damaged, except for the bearing in the rear one. My dumbass self damaged it.


So Im going to be in the market for some parts soon. Just gotta figure out what my next build is. Probably 4-Port Bridgeport N/A.

 

Yup, by anybody's standards that front rotor and irons are fubar.

 

I bought this engine as a street ported engine and its pretty evident that its not street ported, or at least to any template that I've ever seen. I also noticed it was supposed to be an S4 engine. I think one of the rotor housings is S4. I know the endplate is not. The front looks like its from an S3 (GSL-SE). The centerplate on the other hand looks like its from an S4.

Kind of dissapointing to find this. Oh well, at least I didnt break the bank a year ago when I bought it. Accually, thats funny. It was last january when I bought this motor. huh.

Anyways.

 

I compared the porting pics to mine and would have to say some work was done on the endplates after all.

 

If you look at the original port on mine on the far left vs yours on the right you'll see what I mean

 

may those irons rest in peace......(tear)

 

lol wahoo! party at the front rotor! i really like the pic of the eshaft,iron and rotor leaning... its almost art!

 

Your front iron cant be a GSL-SE, the early 13B's had the water jacket groove in the aluminum rotor housing.

 

If A-Spec was still running around I bet not.

 

I think Rx7Heaven in Ottawa might find use for 'em too

Cleaned up the carbon on both rotors, clean up the rotor housings and e-Shaft.

Obviously 1 rotor is toast. The 'good' one has some imperfections but its usable. However, the bearing needs replacement.

E-Shaft is toast. Theres gouging on the front lobe.

Housings are good enough, but they need to be coated. Off to JHB they go!

 

Pics of my secondaries for Gary to compare.

 

good pic, bone stock, should we mention who you bought this said to be streetported engine from.

 

I dont think we need to mention where this engine originated. The builder does enough good buisiness to offset this mishap. Im not too concerned because I didnt pay alot.

 

You're a good man! We always seem to have more than enough **** spreaders.

 

Besides, we won't mention "who" ran it out of oil, LOL. Even my builder isn't waiting at the gas station to check my dipstick at every fill.

 

Looks like the new engine might be built ahead of shedule. Im getting a new job thats going to pay me almost twice what I make now. God Bless the booming oil industry.

 

When did this happen??
