Let me say really quick that, I've been on the forums for about 9 months now...I spend 99% of my time just reading and trying to pick up what I can from the guru's and apply it to my own plethra of knowledge..So a real quick thanks to all of you who have helped me, and others in the past..now onto the guts..

Well my motor finally came out..and when I looked inside I saw destruction...decided to share some of these pictures with you all so you can say "Haha, thank god thats not my motor" -- Its all being replaced with brand new parts, and the housings will have a large street port..hopefully when those come in I can get some pictures of those and the process to you all..Dont laugh too hard..Im admittedly amateur..

 

Typical damage from detonation/preignition. You cracked an apex seal and it gouged up the rotor housing. If the apex seal groove is not distorted, then the rotor may be re-usable. Make sure to pull apart and inspect the turbos/turbos. It is nearly impossible to see damage that may have been done to the turbine wheel when the seal exited the motor when they are assembled.

 

Do you know what actually caused the engine to blow? That's really the 1st thing you need to figure out.

 

When was the last time your fuel filter was replaced ?

 

Nice. Thank god thats not my motor.

You on base at Coronado? Great place to be.

 

Well, the motor never officially blew, but it was well on its way. It was spewing white smoke at idle and just about all of the seals in the motor were blown..it had a pretty rough idle but ran surpisingly smooth after it was on its way. I only got on it a few times, all of them feeling shortlived and always leaving me wanting more.

Eventually I just decided that I had to make a decision, keep running on the soon-to-blow motor until it..blows.. or replace it before I find myself stranded on the side of the road one day because I thought I could keep up with "that car". So I figured I'd take it apart and see if I could salvage anything...to which the answer ended up being no, its all pretty gouged and screwed up.

As far as when the fuel filter was replaced, I honestly dont know but I bought it with roughly 102,300 miles and its only at 104,9xx. I've done my best to baby it because of the motor issues..

And yes I am stationed on Coronado, I was in BUD/S...graduated with class 268 April 8th, 2008...but Im on a med hold for my elbows and my left knee...got pretty screwed up during hell week and never fully healed so they're letting it heal up before I class up for SQT..

 

Yeah, you should replace just about everything listed as maintenance on a car like that. In fact, now that it's 2008 the only things I wouldn't replace are ones that a prior owner has provided proof for.

If I were you I'd try to replace:
- engine wiring harness
- oil metering lines
- all coolant hoses
- thermostat
- fuel filter
- fuel hose recall kit (if not done)
- FPD
- ultrasonic injector cleaning and testing (wait until shortly before you start the motor to get this done so the injectors don't spend much time on the shelf)
- new coolant cap(s)

Props to you for getting through BUDs training... amazing!! I went to a single day of BUDs back when I was in college and phenomenal shape (running track), but the swimming tore me up!

 

Haha yes, the swimming was definitely the biggest challenge for me, took a lot of condiitioning before I was at the point where I thought I was ready. And yes Im doing my best to have everything replaced, but I have to save and buy parts as I go..Im actually in the middle of trying to find the best place to get new motor mounts, also searching the forums to see if there are some out there better than the OEM. Or at least maybe more durable to heat.

 

I'm not so sure I'd be worried about heat related problems to the motor mounts, although maybe other senior members would have some "interesting" stories to tell about this.. rather mostly I think of motor mounts possibly breaking. I kinda like the stock mounts, new ones, because they won't transmit the engine vibration as much to the car.. but if you're looking for high hp numbers then aftermarket ones might be better.

Since you have a new engine you're building and concerned about heat though, you could check out getting some ceramic coatings to the internal engine parts, mostly the rotors themselves. Also, coatings for the dp and manifolds: upper, lower and exhausts.

Here's some links I found awhile back, but of course lack of $$$ was the final factor in what I could have for my rebuild too.

Good luck with the Seal training! Maybe you can convince your unit to have an FD dropped in or waiting for you at the extraction point!!

 

Wow thanks for the site, thats actually something I had heard about but knew little to nothing about. Definitely appreciate that...and I have to say, if that happened, I think I'd just drop to a knee and shed a tear..that would just be the coolest thing..ever....haha
