boost is 7-5-7 and eveyrtime on startup wite smoke. All i have for an exhuast is a catback system.
Anyone have similar expierences or know of what could be wrong?

i whould check the turboes. or could be a seal in the motor.

eeeek. new turbos just put in less than 10k miles. Stupid dealerships.

I hope that they are still under warranty

yea right, it was like a 2 year warrenty or 5,000 miles and I bought th car and looking at the records it was justover 3,000 miles ago. At they were repalced in 98. So forget the warrenty. I have these problems im having with my rx7. Just yesterday a radiator line decided u blow up in my car... it still stinks.
O well

White smoke = bad coolant seal, right? That is how mine is at startup.

It could be your secondary turbo is going or one of your coolant seals in the engine is bad. My guess is coolant is leaking into your turbo exhaust housing. My rear turbo went and i had a HUGE amount of white smoke out the exhaust, and only7 pounds of boost.
good luck with it

not good.. if your radiator line blow up.. I think its signs of coolant seal broke in your engine.. but I could be wrong.. is it over heating??

okay, some of these repsonses are just stupid.

I HIGHLY doubt its your motor. It should not just all the sudden puke out a crapload of white smoke . Coolant seals go gradually.

And you said that your turbos suddenly boosted less, with the 7-5-7 , so Id inspect those turbo's. Start by taking off the intakes for both of em and expect the turbines. See how much shaft play you get, and check for crazy amounts of oil. Then check the coolant lines and oil lines to em. To me it sounds like you got a weakened set.

so just check em out.

Wheeeee yep lots of work, might as well get off my lazy *** and finally do something about this. Maybe ill find the energy to put my midpipe and downpipe on too.
Thanks

My coolant seals went instantainiously. get ready for the loss of $5000.00 and 6 weeks of your spare time

I agree with you.. Most people's coolant seals go all the sudden.. I personally know 3 people who lost there engine due to coolant seals.. two of them with newly rebuilt engines (less than 1000 miles) and one with 11k on the mazda reman.. I own the 11k reman engine now and disassembled it to know it was the coolant seal...

Since I'm "Old Geezer", I'm just talking stupid.. And sure Mr. Rx-7$4$me knows much more than me..

Rx-7$4$me

heh. People were saying that coolant seals would GO like blowing apex seals. Instantly. When I said they would go over time, it could be over a few days, or say for example if you overheat it, the results might not show up for a few weeks.

if u want to tell me that your coolant seals were fine suddenly while driving, and then all the sudden puked all this coolant into your motor.... go ahead.

Is it how your coolant seal go.. graduately over days..?? only reason I'm giving you a hard time is because, I'm an "Old Geezer" and when you get old, You become like this.. An *******.. So, something to look foward too..

Far as coolant seal thing... yes, when your coolant seals go.. you will know.. its pretty instant thing.. I don't know what others been telling you.. but with the pressure and heat from the engine, any small opening/tear in your coolant seal will leak coolant into your combustion chamber or gas from combustion chamber will go into your cooling system.. And it could be small as pin hole..
Thats the reason why I asked if he was over heating.. when the gas from combustion chamber goes into the cooling system, it will over heat the coolant and you will definitely see the temp increase.. This is pretty much the same as piston engine and rotor engine..

I hate to give you a hard time.. but don't call people trying to help as stupid advice and calling them, "Old Geezers".. especially if you are not sure about your own comments..

Rx-7$4$me

okay.. MY geezer referance was not even mean to be interperted as you older people not knowing what u were talking to. It was said to show the older people, who think that 17-18 year olds cannot maintain and take care of an FD, that it is indeed possible. You just took it offensively, and it wasnt even directed at you. Many think that the younger generation of FD owners are completely ignorant and incapeable of owning FD's when its simply not true. Saying your an ******* due to your age is just rediculous.

Depending on how the coolant seal was damaged in the first place will determine how fast it goes.

When you overheat the motor, the damage done typically donest show up for a few days, unless its in the form of warped rotors. Then you will know hehe. But if its a coolant seal, it might take a few weeks for you to start watching the coolants dissapearing magic trick.

first, the coolant starts to dissapear a bit, and you have no idea where its going. Then you get the dreaded coolant buzzer, the white smoke etc, as the coolant seal's damage starts to worsen. I never said anything about not knowing right away if your coolant seals go, but sometimes you dont IE the overheating case.

Most of the time its a gradual death, and not instant deaht like blowing an apex seal. It progressivley gets worse over time. untill its undriveable.

and I was never unsure of my own comments.

how does blowing a radiator hose pinpoint that the motor is gone? people blow coolant hoses off all the time. its too common of an occourance to say its due to failing coolant seals.

White smoke isnt ALWAYs coolant seals. it can be blown, or dieing turbo's as well. And since he said he lost the normal boost pattern, one would assume its teh turbos over anything else first.

My seals went all of a sudden. I went on vacation, and when I got back, my 18 year old son had taken the neigborhood for a ride. when I got back, the seals were toast. i'm an old geezer too. comin up on 45 this october.

Rx-7$4$me

yeah but when did he take the car for a ride and how many days did u get home after that? If it was sitting there for a while, it could have gotten worse while you were gone.

No more old geezer!! I didnt mean to be offenseive towards you guys jeeze lol.

Rx-7$4$me,

I'm sure you are a smart teenager and you love your FD.. I love my FD..
But if you would re-read your posts.. It does offend old geezers like me.. I could generalize but I don't.. We all have different level of experience on this particular car and some are true and some are not.. What you are saying could be true.. Yes, you could over heat and not notice any symptoms of coolant seal going bad.. because it didn't go bad..

And yes, white smoke you see in the rear isn't always a coolant seal in the engine.. it could be from coolant getting into your turbos.. That I agree.. But, when your coolant hose pops, its due to couple of things.. If you go back and read my first post, you will see that i'm trying to trouble shoot what it could be.. if he over heated and coolant hose popped.. I say its highly possible that coolant seal went..
But you just post, that some of the responses were stupid?? Like you said later on your posts, there are many possiblities.. so, don't say someone else's comments as stupid, especially if you aren't sure... Hope this make sense..

And I also know few 17-18 year old FD owners in AL and TN.. and you know some are very knowledgeable and some arent... I try not to stereotype them because I have also seen 30-45 year old grown up man who's worse taking care of their FD.. I hope you also try to avoid generalizing us old geezers..

ok, i have a question along these lines too...

right now when my car idles, its blowing a little bit of white smoke, im having the same boost pattern as explOd, but i did find some oil in my Y pipe but nothing after the intercooler, does this sound more like a turbo issue or a coolant issue?

Rx-7$4$me

Seriously herblenny, I never truely had the intention of insulting people older then me. It was really just a joke, and if it offended you im sorry.

This is just not true. Sometimes it takes some time for the damage to take effect. its been proven that overheating doesnt ALWAYS have immediate results unless its in teh form of warped rotors. but sometimes overheating wont do anything.

As you can see, when a turbo goes, it also pours white smoke out of the exhaust. ONE would think that because of his SUDDEN crappy boost pattern, it would most likely be turbo related.

People are basically telling him that his motor is gone, indefinetly when it just probably isnt the case.

If a radiator line actually EXPLODED, and I dont mean that the lines vlew off where they were connected, it could be as you say. But thats rare as far as im concerned, especially since he mentioned nothing about it.

explOde if you start the car and its humid, u rcently washed it, or there is any form of condensation in the exhaust there will be white smoke.

Id take off the intakes to each turbo and do the following.

Check for shaft play by gently pushing the compressor wheels to the side. Dont go slamming them around or anything, but they should move like a mm or so. There shouldnt be much over that.

Spin the turbines. they wont spin that easily but they should be able to be spun by hand with no rough noises like they are grinding against the housings.

and then of course, check for unnecesarry oil.

since the dealership put them on, they probably f'ed somthing up and it could have shortened the life of them quite a bit.

A bit of oil in the intercooler piping is normal, as long as its not an excessive amount.

Both of you should list your mods and describe what happened before your boost patterns went to ****.

I mean if you just did the vacuum job did you remember to put the pills back in? no pills will give you about 7 psi.

just saying your turbo's have a crappy pattern could be abillion things and one to do with the turbo system.
