1987 supra turbo ?'s

[DaBoss07]

A little bit less expected than what I saw yesterday. Drove out to see this supra yesterday and just to say a couple of things were wrong with it.

Windsheild had a crack in the top left corner coming across,
the door handles were a little loose,
normal wear and tear on the outside (paint starting to fade),
looked and sounded like the radiator fan was knocking a little bit when we got up to speed,
I dont know if it was the turbo but something to the left was making a clug clug clug sound when it idled and drove,
also there was white smoke coming out of the back on occasion (he said it was from the fuel injector cleaner that his son added and he didnt know why it was smoking, said it had never done that before and they were running premium fuel in it), I think its from getting water in the block and or the head gasket.....but they said they replaced the head gasket a little bit ago.

If I can find out the reason of the white smoke would be great.....cause thats the only thing that bothered me really. If someone can give me some advice that would be great.

Does anyone have any information for me?

Dont you dare concider putting and american engine in that thing of beauty, if u want to do that just buy a camaro, u can find a 1 jz for a round 1000 on ebay saw one the other day, if u want a car the will bring u joy for another 20years, keep the 7m, get a 1jz, r a 2jz

White smoke...it may be burning oil form turbo/engine or coolant from head gasket. Try to remeber, was it smoke, or it looked more like steam?
Sounds are bad, it may be con rod bearings ...I guess, that engine gonna die quite soon(((
What was the oil pressure during the ride?
Also such sounds may do untied crankshaft pulley...it's also very-very bad

And one thing I know for 100% - Supra must be only with japanese engine...better with jz-series

[will fight for food]

sounds like a BHG offer him 800 if he wont go under a grand then walk away that thing is going to need a motor and dont you dareput a v8 in that thing go with the 1jz or 2jz or hell just put the 7m motor back in it but DO NOT disgrace the supra with a v8 swap

[DaBoss07]

I didnt get a good look at it cause every time I would bend down to try and smell it or touch it.....IT WOULDNT BLOW OUT. But it did feel like there was just a little bit of moisture coming from the exaust because I could feel that.....

Well I was thinking about trying to get a whole new engine put in the thing.....and I wasnt going to put anything other that something that would bolt right in i.e the 7mgte.....But this would be a project car for me no doubt.....but I think while im out there on friday im going to take it to a shop and have them do a 101 point test on it or whatever so they can just look at it and tell me whats up.....I thought that was the safest way to go instead of buying a hunk and have it go out on me within the next couple of months...........but like I said it was going to be a project car for me.

White smoke and/or steam is generally coolant getting into the cylinders, and can mean a BHG (most likely), cracked head, or a cracked block. That the seller says they just replaced the hg a little while ago does NOT mean that they knew what they were doing and did a good job of it or that it fixed the problem if it wasn't the hg.

BTW, oil in the cylinders will give you greyish-dark smoke, and excess fuel (running rich) will be black.

The radiator fan knocking sounds like they may have screwed up the keyway on the crank where the harmonic balancer mounts. If so, that would really screw up the crank bearings given time. With the engine off try and rock the harmonic balancer a little, and with it running look and see if it's oscillating.

Not sure what the chug-chug sound is, though it "might" be compressor surge if the BOV isn't working properly.

All in all I'd at least do a test for exhaust gas residue in the radiator. Most radiator shops can do it quick and cheap, or you can do it yourself. That ought to tell you if you're looking at a bhg or not. In any case I'm not sure that I myself would trust the guy selling it. JMHO.

Oh, all rumors to the contrary, a properly maintained 7M is a good engine which can and will last a long time. There's no need to go to a non-7M engine in order to get a reliable engine so long as you take reasonable care of it.

Well most engines that are maintaned and not drove into the ground are going to be reliable but yea I know what you mean. Yea I think thas what I am going to do is take it up to a shope and find out what the white smoke or steam is.....cause he still says its from the fuel injector cleaner into it.

[mirage83]

Fuel injector cleaner won't cause white smoke. So if you're serious about the car definately take it to a knowledgeable shop and have them check things out if you're not interested in doing it yourself.

I'm having a little bit of a similar problem with the smoke right now. I just bought a running and driving 89 turbo for $800. What is getting me is that the engine is running strong with no lag, and it actually runs at a decent temperature. The only time smoke comes out is under acceleration, and maybe a little puff at idle. Any Ideas on if it might be an easy fix?

The seller had a HKS controller wired into the ECM which I removed and that helped an idle problem. I'm wondering if the ECM got messed up by the installation.
