When I start my 1987 rx7 it smokes like crazy real thick white smoke. Then it will clear up after a few min. some one please help.



Then when the car shifts out of 1st gear it skips 2nd and goes to third. Auto trans. Please Help.

Sounds like you have a blown coolant seal. Inspect all your cooling system hoses and connections, check to see if your reservoir is consuming coolant or boiling over, etc.



But usually with a blown coolant seal inside the engine, it will burn coolant until it warms up enough for the thermal expansion to close the gap just enough to bring the smoke level down...

Do you have nay idea on the cost of repair for this problem.

Thanks, egc87rx7

You are looking at engine replacement





There is a larger price gap between turbo and naturally aspirated models



You are looking at anywhere from $500 - $3000 depending on if you are doing the work yourself, or sublet for a professional, using a used motor, new motor, etc..

wait wait wait, does that smoke come out of the exhaust tips or from under the car?

It comes out of the exhaust. I seen on a previous posting the same symntoms as my car is having and they recommended that it needed a new fuel injector. To let you know again the exacts. When I start the vehicle up it blows out an enormous amount of thick pure white smoke. The car had been setting for about a year and a half when I got it last weekend. I put a fresh battery, and five gallon of gas in it. I got in turn the switch over the engine turned over about five time before it started but when it did it fired up idled as good as you could ask for it to. It never died but it blew the white smoke I was describing. It lasted for a good 10-15 min before it cleared up. My friend that I got the car from followed me about 15 miles back to my home it never smoked any on the way home. I turned it off and some 3-4 hours later I came out and washed it good staarted it up to pull it in the garage to wax it and when I did it blew the white smoke again for about 3-4 min. Car runs, idles fine seems to have plenty of power. No fluids in the oil, antifreze, or transmission that shouldnt be there. Thanks in advance for any further info. Or let me know if you think it needs a new engine ect. I hope not it runs too good seems like there would be an easier fix????

the smoke of your from your engine is normally caused rom ur cataylatic converter. This is a hose that goes from ur intake manifold to your catayltic converter (main converter). Make sure its hooked up correctly. Depending on how long you been driving without that hooked up could clog it. This happened to my exhuast when i was rebuilding my rx7. Simple fix. The caty needs air to burn the fumes.



I would not recommend to find one to repair the coolant seal. Id fix it yourself. It be rare to find someone that could fix it and if u did you prolly be paying a pretty penny.

I WOULD recommend finding someone else to repair your coolant seal, chances are they know how to repair it better than a do-it-yourself-er would. Rotary engine rebuilders are NOT rare.

My 1991 rx7 has a pipe sent from the intake manifold to the catalytic converter. Its meant to feed oxygen to continue burning its by products. If they dont burn, the caty will get clogged esspecially over time. When i didnt have it connected and ran it, mad white smoke came out. hooked it up, it was perfect.



Anyways, In rochester, ny u wont find many rx7 rebuilders. i guess its just the weather lol. trust me ive asked around.



If this doesnt help. im sorry.

Anyone who starts off a techinical post stating "smoke is usually caused by your catalytic converter", clearly doesn't have a grasp on how things work. So you aren't in any position to be telling people how the EGR system works and how it prevents "mad white smoke yo" from coming out of your exhaust.

Whatever u say, lol. I rebuilt my engine from the ground up. Just trying to help. Criticism is for the bluffers. https://www.nopistons.com/forums/pub...IR#>/smile.png i'm out of this forum.

if its blowin a lot of white smoke just when you start it up, it may be the fuel injectors. when the car is off there is still pressure in the fuel rails, it doesnt get relieved, so if you have a leaky injector it will empty enough fuel into the chamber to relieve that pressure... when you start the car it will cuase it to blow white smoke for a while (if its not flooded beyond belief). Try just getting your injectors cleaned before going for an engine rebuild

I hope you are right I had read the same thing on another forum. I believe it is worth the cost of a fuel injector to find out. Besides if that doesnt fix it I will be buying another car and using this one for parts because I love these rides. I have a brand new Lincoln Ls sport, A new F-350 diesel and I would still rather drive these cars there just alot of fun to me. Thanks, I will let everyone know if it was the injector or something more serious... Thanks again to everyone.

Just wanted to let everyone know I had only started the car about three times since I had got the car running after it sitting for a year and a half. I started it again Saturday morning and drove it and have done the same three times since it has never smoked one bit I believe that my friend I got the car from was right it was just the oil and stuff burning off where he had put it into the spark plug holes to help it get compression to get it started and he could not get it to start and that oil and starter fluid he had sprayed in there must of had to burned out. So now I am down to finding out what is wrong with the automatic transmission it works fine in 1, 3, 4, and overdrive but it skips 2nd all together. I did notice backing up my driveway once it seemed to slip a little in reverse but all the other gears are very strong I have run it hard to make sure they were not slipping. If anyone can help I would appreciate it. And just to let you know I have tried shifting it manually thru 1, 2, drive, & overdrive and it will still not go into 2nd if you have any ideas let me know thanks.

You should have let us know that from the get go.. Otherwise we are assuming everything USED to be OK when you were driving it all the time, and suddenly you have a smoke problem.. https://www.nopistons.com/forums/pub...IR#>/smile.png

In a series 4 it provides backpressure, in a series 5, intake air is supplied to the catalytic converter.



smoke is not caused OR prevented by the catalytic converter!

Sorry I am mostly S4 backround, I just got a little heated over hearing that my smoke problems were caused by my cat... https://www.nopistons.com/forums/pub...DIR#>/wink.png
