I have terrible, terrible NEWS
 

on friday just 2 weeks after a year in the making I blow the freaking engine and these are the only friends I have right now along with the 20 something beers I drank friday night I was pissed, gonna crack it open next saturday & see how bad the damage is.

Sucks to hear man, I feel your pain. Don't spend too much on drinking though. The money spent on boos can go towards your rebuild.

what happened?

What do you think happened? What AFRs did your tuner shoot for? Were you pre-mixing?

the tuning is fine frank @ world wide racing in opa locka,FL. yes I am premixing, the engine just didnt hold. it is a 93 and its was just sitting in the previous owners garage since 2000 till 05 when I got it.

How many miles on it? Engines don't just break.....it was only 15 psi on a smaller single turbo.

thats not even the worst news some of U know I had a replacement for this same occasion but sold the engine to someone else.

"SUPPOSEDLY 41K" but I'll know for sure when I crack it open. if u check some of my previous posts I started to suspect that this engine didnt have 41K on it.

Go with the Bacardi, the other will leave you with a nasty hangover.

Sounds like you had a junk motor, or there is some other problem you're not aware of. Do you have any EGT or AFR readings? At 15 psi you should be able to get lots of mileage out of a 13B.....

my egt reads 10 and the hottest 12

danm sorry to here that, good luck and keep us posted. on what was wrong with the motor

as in 1200 degrees F peak? Your motor should *not* fail at that level. Sounds like you may have had a high mileage/shoddily built motor. How exactly is it blown, what is it doing?

I know I lost the coolant seals alot of white smoke the spark plugs are wet, cant see a thing behind me, cuz of the smoke, and detonated a couple of times.

that sucks dude....im waiting for mine to go....i bought the car knowing that i would be replacing it...might just rebuild it and be done with it....

well, detonation and blowing a coolant seal are two entirely different events, you're saying both happened to you simultaneously? Did you overheat the car? how do you know you detonated? Just trying to help you sort this out, more details will help.

my temps reached 300 degrees.

I have seen 2 N/A motors detonate from being overheated. Too much heat can cause preignition. Its weird opening one of those up.

i would rebuild asap to hopefully limit the parts that need replaced.

i plan on it...had the car 4 months and drove it maybe 10 times...a total of 200miles... :)
winter time is here....i think its time...(streetport... :icon_tup: )

and if an fd overheats one time , its pretty much one time to many, correct???
you could kiss your motor goodbye...correct??

Mine only had 27k when it went. Thats what happens when you buy a used car as you never know how it was treated, or how well it was put together. Shit happens, I'm not upset about it.

BUT, it will have a new motor soon, and it will be treated properly, and it will last longer than 27k miles. Fuckin better :lol:

Everyday that you own an FD, drop 20-30 bucks in the glove box....maybe you will get lucky and always have enough to pay for broken shit :lol:

^lol^ thats a new one i have'nt heard before

Get it right.. Whenever you do a WOT run throw $20 in the glovebox! AHAHA!

hahah i was thinking the same, swear jar kinda shit, everytime you smoke a vette, porshe, or anything worth it, throw 50 bucks in =D

Just put it in the bank.
You know, I'm a true believer of keeping spare funds availble for these cars for the obvious reasons. Sorry to hear. Unfortunately it's such a common thing I sometimes wonder why I even bother with it you know? Good luck with it!though!

what if all i have is food stamps?
is that okay??.......

how bout monopoly money....that's just as good right...?:rofl:

No way, it's the other way around man :P:

chaser. no hang over

I know this is besides the point and this thread is a couple montha old but I hade a blown coolant seal and it was blowing tones of smoke. it was my only car at the time so you know what I did.. drained all the coolant and put regular water it doesnt burn white like coolant or smell. Pluss coolant has smaller molocules than regular out of the tap water so it getts into smaller cracks I ran plain jane water and drove the car another month before I got another motor.


Chirs

Oh damn, I would start with another core :(

Good luck with your rebuild, you may get lucky like I did. Mine was massive coolant seal failure, and everything still was in good shape internally, just full of water. Instead of drinking, I got to work straight away in a bud's shop and we had the motor out and on a stand a few hours later. Next day, we finished tear down and started cleaning everything up. 2 months later, its a completely different car. Stock port w/ stock twins to Large Street w/ Single turbo made it a whole new animal. :)

Entirely different events? Not necessarily....

Did the coolant seals go first? Any ethylene glycol based coolant (common antifreeze) in the combustion chamber will severely reduce the octane rating of the mixture and result in detonation.

Once again: Any antifreeze in the fuel mixture will cause severe detonation. I don't think this is widely known as it is counter intuitive, but it is fact. It is probably responsible for many unusual, unexplained detonation related engine failures.

To this end: Never, never, put ethyene glycol into a water injection system!

i'll join you in the drinking game, i'm waiting for a new engine myself..

Hmmm, a friend of mine has been running windshield wiper fluid (water, meth, small amounts of ethylene glycol) in his FD's aquamist system since about 2001 on his dedicated road race car with zero problems. I have been doing the same thing for about the last year on my FD. Perhaps there isn't a problem b/c the w/w fluid contains only traces of coolant?

Btw, I'm not doubting you, but I've been around these cars for almost a decade and have seen many many blown engines as a shop owner and engine builder and have never seen anything like what you describe.

I can't speak specifically to rotary failures except to say that ethylene glycol in the concentrations normally encountered in coolant will promote detonation in any internal combustion engine.

I don't think it's well understood, but coolant ingestion often leads to seemingly unrelated failures in piston engines. A common scenario might be a small head gasket leak in which coolant is introduced into a cylinder resulting in detonation in only that one cylinder--which sounds like a rod knock (and is often mistaken for one) typically collapsing the piston skirt and/or top ring land and pounding out the rod bearing--eventually leading to a real rod knock and lot of junk parts shortly thereafter. Oh, the engine just blew.... just being the key word.

Anyway, I have never seen it discussed in the rotary forum, but I want to raise the point that if a coolant seal fails in a manner that leads to raw coolant getting back into the intake cycle of a running rotary engine, then it would likely result in detonation. Therefore, there may be detonation related failures that were caused by coolant leaks, as opposed to AFR problems, overboost, timing, etc.. Unfortunately, it may be difficult or impossible to tell exactly what caused the onset of detonation and if it was a cause or effect.

I don't know at exactly what percentage of dilution the ethylene glycol ceases to be a probem. At the usual coolant concentrations it will definitely cause damage and it doesn't take much (by volume) to do it. My point was really directed at someone who might be tempted to dump regular antifreeze in their WI during cold weather or in lieu of methanol--don't do it!

Rich, I am curious as to just how much ethylene glycol you think is in your washer fluid mix.

Joe

this thread fails without pics of torn down motor and carnage.

BMW windshield washer antifreeze:

Ethanol < 65%
Propylene Glycol < 15%
Alcohol, Ethoxylated, Sulfates, Sodium Salts < 5%
2-Butanone, Ethyl Methyl Ketone < 1%
Water < 30%
Volatile Organic Compounds 56.4%

Took this directly off the label. Of course this is concentrate. Then we fill it the rest of the way up with water.
