My engine GONE!! I'm so sad!!!
 
Well, its official.. My engine needs to come out and new one will be going in very soon!! Hopefully before first weekend in Sept.

Cause, Bad coolant seal. It over heated to 124C last weekend in Nashville, TN!

Luckily my new engine is ready and will be broken in this coming wednesday night.. On a table for 3 hours and compression tested..

I'll be taking some videos and pics of that process.

Was that the stock engine? I got to 112 highest on mine when the fan relay went out. I guess the 12 degree difference is huge and my engine is new so it can take it!

Good luck with the new engine polish it up like mine and if you get a chance tell Bryan at bnr to hurry with my turbo : )

Your car looks fantastic I wish I wouldn't have wasted all my money under the hood

Dude, how could you have let it go to 124C (255) on water and coolant? Tell us the whole story.

Now that you're putting in a new engine, you may want to consider evans NPG+ as 255 F is nothing for Evans.

xstacy7 08-06-04 12:17 AM

Phil......NOOOO!! That really sucks big time. What was the actual problem after all of that mess? You'll have it back and running in no time. Damn sorry man

94RHDFD 08-06-04 12:22 AM

Well I guess the photo shoot this weekend with all the hot models is out now, unless you want to just tow the car done there.

Phil, hey man it's Charlie

I just got my new issue of RXTuner mag, and I saw some pics of you and your car in there! Then i come here and I see this! Well, atleast you're prepared, already got the ball rolling on the new engine, sounds good! Make sure to keep takin pictures of that beauty for us once it's back on the streets.

ps, you going to Petit Le Mans this year? If so, let me know, I'll see ya there!

Well, it started off with small over heating.. i think it was due to my 115MPH trip to Montgomery, AL.. I was averaging that for about an hour trying to make my appointment.. but never hit more than 96C during the cruise.

At my first guess, I thought maybe my coolant went out.. saw small amount of white smoke at start up.. but saw that for couple of years and never over heated..

Anyway, on my way back, almost to Birmingham (85 Miles into my trip) my temp started to rise.. hit 110C... But that was in neutral and about to pull over..

Tried different things and than went to Nashville the next weekend.. there I met up with HDP and xstacy7, heading to Murfreesboro cruise in.. on our way, my car went from 96C to 124C in less than a minute. The pic above is after hitting 124C.. all the coolant pretty much left my system.. Thanks to HDP and xstacy7 (they went to some random house in BFTN and brought 3 gallons of water for me)!
I think I put in about 1.5 gallons of water back into the system..


John (20b3rgen), I'm cleaning my garage to pull my motor this weekend.. And I'm going to go pick up the RZ tranny. Also, Next week (wednesday or thursday), I'm going to crank and break in the new engine.. If you want to go up, let me know.. I think Stephen might go also.

Charlie, Can you scan that pics from RXtuner and send it to me: philipsohn2004@yahoo.com
Most likely, I'm going to try to go... We were going to have our annual BBQ that sunday.. Hmm.. maybe we could do both.. I have to see..

Thanks!

Oh.. yes, it was my stock engine with around 88K.. I knew it was time.. just wanted to extend the life for another 2 months..

Sorry to hear about the engine Phile. I like those wheels (wink, wink).
Like someone suggested, use NPG+, you can run the car at 125c all day and not have to worry, not that you would, it's just nice to have the safety margine.

SlingShotRX7 08-06-04 09:45 AM

Herblenny..

So you saying that you already had bad coolant seals.
and during your Trip your Motor burnt up most/if not all
the coolant in the car, to make your car engine toast.

So during yoru cruise while your engine was eating your coolant.
and running low on coolant. ISn't your LOW COOLANT
light on your STock TEMP gauge suppose to light up and buzz??

Does our FD cooling system suck COOLant from the OVER FLOW back
into the motor??

BTW goodluck.. Now time for streetport and Single turbo.. and have alot
of fun

So, should I go with NPG+ or Distill water + water wetter?? I've heard distill water w/ water wetter will have higher heat exchange and over all better way to go..

Also, I'm now thinking aboug getting rid of my ast and sticking T2 filler neck??

93BlackFD 08-06-04 09:47 AM

wow phil, that sucks, but you've been aware of this pending disaster and have been making alternate plans, so that's good

It wasn't burning any coolant.. I think the exhaust gas was coming into the cooling system.. No smoke except when the car sits for couple of days or longer.. which seemed normal since I've seen same thing on other cars and also on mine(before this whole coolant seal thing)..

After it dumped out all the coolant, the buzzer did go off..

Yeh, My new engine is ported.. street and some custom porting that my builder did.. And sometime this fall I might have a single and steve kan will tune it.. hopefully at the same time SPOautos gets his car running..

Yeh.. but I was hoping later on.. Damn.. I'm also going to put dual R1 coolers in.. All the shit that I been collecting for years will now finally go in.. Hopefully my car will be worry free for next couple of years..... LOL!! thats not going to happen..

Toadman 08-06-04 10:44 AM

Sorry to hear. You've got PM. :(

Check out the various Evans threads. From what I've read, water is an inferior coolant b/c we use water near its boiling point. With FMIC and hard driving, we easily overtax water's cooling capacity.

Converting to waterless Evans will help the cooling issues inherent in the FMIC setup b/c Evans Nonaquaous Polyethylene Glycol + (NPG+) liquid has a much higher boiling point--375 F at zero psi cooling system pressure (probably closer to 400 F with higher cooling system pressures). Theoretically you should never reach 375 F engine temps. The limiting factory in keeping your motor cool are oil temps (250 to 275 F). Add an additional oil cooler, if you don't have an R model FD.

Best of luck with installing your new motor!

Bummer Phil! Sorry to hear about your motor.

Nice pic in RXTuner. BTW the cover vehicle was my old TII. It was purchased from me and then traded for a bike!

sorry about your motor, but at least you have a chance to port shit now :)

spoolin93r1 08-06-04 01:47 PM

damn man, that sucks. good to know you got that new motor that's been done for a little while though. good luck gettin it all back together

rx7tt95 08-06-04 05:10 PM

People seem to forget that REGARDLESS of what coolant you use (regular or Evans) you cannot overheat a rotary. Just because Evans doesn't boil at 750F (or whatever) doesn't mean your motor will survive. It won't. The aluminum/steel side housings expand at a different rate from the iron side plates. Overheat the motor and you'll more than likely expose the 0-rings to combustion heat and that's all she wrote. Time for a new engine, even if you're running Evans.

FDNewbie 08-06-04 08:48 PM

Damn Phil...I'm sorry to hear that. 88K miles, eh? You got me all paranoid now...mine's at 83K!

Im glad you got eveything in order, and will have a chance to install all the misc parts you've been wanting to. That's hot man. But sorry about the engine nonetheless.

What's the deal w/ the RZ tranny? Anything special about it?
