Hey there, I have a 88 TII w/ 55kmiles now, anyways today i ran into some trouble. Please help me if you can. I Was driving to a friends house and stoped at a gas station and left the car to idle, when i hoped back in and went for a brisk drive the car seemed to run choppy and a little rough, the boost gauge was bouncing too. Then I poped the hood on the side of the road and thwe engine was dancing (shaking ect.) The car normally runs very smooth w/ ocashional jump in idle approx. 50-100 rpm which is common. Well i hopped back in hoping to make it to my friends house and then it ran like **** and died. Tried to jump it w/ a friend of mine, no luck, tried to turn it over w/ high beams on to see if they dimmed out as a sign of a bad alt., they didnt. Well then we put a cuple of gals. of gas in it as it was less than a 8th of a tank and no luck. We then towed it to my friends house w/ a rope. When we got there from tring to crank it while moving i noticed smoke coming out the right tail pipe.

It almost turned over when i was being pulled the idle jumed to 600 but died again. I am wondering what to do???? Here are my mods incase that helps....
Tid mod (didnt look loose either) w/ air filter. Racing beat dp w/ pre-silencer. So no cats. Thats it. I ran at the track 4or5 times, my best time being a 14.2 at 97mph. The car never even got past half way on the temp gauge. It has always ran great. I have recently got a new starter, that went out a couple of months ago. Other than that no problems. Please help me , maybe one of you know whats going on or have had the same prob. before. I seriously doubt the motor blew up. Can it happen just like that...no werid bang or boom...i doubt that happens but I am not sure. w/ 49k babied miles by a 65 year old (org. owner) and 6k semi-aggressive miles by me, I doubt the moter would go like that. My guess would be a fuel or electrical prob. , maybe the leading/trailing colis?? Or fuel pump failure???? Im open for suguestions. Thank you guys for any help....

Babied? that doesnt sound good. Carbon buildup... your being rough on it cleared some of it up... maybe a chunk broke off and took out an apex seal?

Anyways i dont wanna scare ya... but do a compression test first.

Next, what colour smoke was it? Black is okay, could have been just flooded
Its possible that one of your injectors is stuck open and constantly flooding it.
Then again, could be a compression issue
Next, run code scan. A sensor could have crapped out (tps, afm).

And most importantly, good luck!
(btw, if you're not far from Raleigh, i think there's a rotary shop there if i'm not mistaken)

#1 job should be compression test. You dont even have to use a gauge, just your ear to check fo all pulses...better yet have someone crank for you with both lower plugs removed and put your fingers by those holes to feel the pulses, should get one per rotor per rotation, front-back, 6 in a row.

If you pass that, I would look for a big intake leak of some kind...tid or IC piping having come off, afm unpluged, etc.

Hey thanks for the advice, the smoke of the exaust is black w/ white smoke. We have a video of the sound w/ visuals of smoke. Keep coming w/ advice.

I cant do the compression test b/c i had to leave for charolotte for a college registration, ill be back on tues. The video is coming on my next post.

What the **** did you do to that car? That does NOT sound normal. Can only heard the audio right now, lemme update my codec so i can watch it.

wtf! that video is a big help, btw, but still!! wtf is going on!

all that smoke WHILE your trying to start it suggests to me that its flooded with coolant/water or something

****** wierd!

ForsakenRX7

Sounds to me like you now have lil to no compression. Yet it sounds wierd even for having no compression. Check your radiator. See if your losing coolant. I'm willing to bet you are and thats whats coming out of the exhaust.

hypntyz7

Yeah dude, from an experienced ear, that sounds like at least 3-4 blown apex seals. It actually sounds like you only have 1 face making compression, instead of 3 (one whole rotor). ON turbo engines, this is not unheard of to blow seals on more than one rotor all at once, because fragments from the first one go out the exhaust, hit the turbo, get tossed back, and enter the opposing rotor through the exhaust port. Im workin on a rebuild for a guy right now, and this happened...Ive seen it 4 times in 2 years now. Regardless, run the compression test, if only by ear.

ForsakenRX7

Yea I'd definatly say its rebuild time. Each time I watch that video it makes me cringe. But hey, its a nice lookin TII you got yourself there though.

2a+RoN

GUESS WHAT!!! That sounds really similar to mine after I had an apex seal blown, but yours sounds a little worse... Mine would still start while being towed though, it just ran like **** and wouldn't hold idle. Hopefully you have some money saved up for a rebuild. I didn't and I haven't driven it in ~3 months!!! just a few more weeks....

2a+RoN

I feel for you though. Like everyone said, do the compression test when you can just to make sure.

49Kmiles

Well I apreciate the advice, When I get back to Fayetteville on tues. Ill prob take it to the only rotary place here. The one in Raliegh (clean and fast roatry) is more reputable, but i cant go 60miles...Well i still cant believe this, Ive got 55.6K miles. Damn, I am going to college in 1 month!!!What the hell do I do, Ive got 300$ in the bank...thats it and its for college ****. First before i trip over a blown motor ill take it somewhere first. Does the motor when it "blows" make a noise other than shitty idle? Im fucked if my motors gone, well ill let yall know, keep up the suggestions.

Nah the rotary blows quietly. If it vibrates real good at idle, it is blown.

Sometimes they just go even when you are not being hard on them.

this is very true!

i have a 13b n/a from an s4, an apex seal blew, and a chunk of it shot out, and couldnt make it past the exhaust port baffle before the other apex seals swept by.

its sitting on my desk as a display

anyways, each face of the rotor has serious gouges, and every apex seal has been gouged/scraped, not to mention the gouges on the housing!!! the entire rear rotor and housing is garbage..

well not garbage, just not reusable.. they make a neat desktop item if you wirebrush everything until its really shiny!

I got back today from my college registration, I went to start it, no good. I checked oil...Seemed to be full. I just got the oil changed 500 miles ago. There IS oil in the coolant. Now tell me how the hell that happened? Whats this mean?

Thanks

something is definately wrong.. oil in coolant and your burning coolant when you turn it over

pull out your lead plugs, pull out the egi fuse, and get someone to crank it over with their foot on the throttle.

ill bet you gots no compression boy..

should sound like a steady chug.. like a train..

hypntyz7

Why is it that most people absolutely refuse to take 5 minutes and run a poor mans compression check, rather than check everything under the sun in denial of the most likely problem, against everyone's advice?

Black13B

iTrader: (1)

no kidding eh!

especially under the advice of the owner of Rotary Ressurection!

seriously.. the ghetto compression test (aka poor mans compression test) takes about 2 minutes. and it beholds the most important thing to know before spending any money on repairs..

hypntyz7

Well, it doesnt matter that it's me thats giving the advice, as long as it's reasonable and sound, and repeated by several individuals, it must be the way to go.

I mean, if Im asking why my car wont run, and everybody says "check to see if there is gas in it" and meanwhile Im up there checking the ******* turnsignals, somebody at some point has to ask

Rx-7Blazin

i think its cuz you dont want to see that you just blew your engine but oil in the coolent not sure aboout rotorys but in a piston if there is oil in the coolent you blew your head gasket which would be like a water seal in a rotory

2a+RoN

my car sounded like that for a while and I avoided checking the compression just cuz I didn't want to prove what I had already known I was in denial... but its better to just do the test in the beginning to get it out of the way and so that if it is blown you KNOW what the problem is and you don't have to troubleshoot trying to figure out the problem.

49Kmiles

Well Ive done the dreaded compression test and the motor is gone... Now time to try to get a loan for a rebuild. Has anyone comparison shopped around for rotary rebuilds...Rotary resurection seems like a decent price, Cumberland Rotary wants to charge 2,200 + install and removal + whatever internal parts cannot be salvaged. = tooo damn much $$$$. Prob. a good 3000 bucks if i went w/ them. Well thanks for all the help, and I did have a feeling that this was the prob. the whole time, I just didnt want to believe it.
