Awesome trochoid. Really appreciate your knowledge. I suppose this thread is pretty much dead as it has answered my question, but I would like to continue discussion here.
It would be feasable then to purchase a 89 13b longblock with all componants for the 500 I found then...20k miles verified to boot! I can strip it down to the block and store it for a rainy day then. If need be to swap into my chassis ever I only need to utilize my old oil pan, dist, crank sensor, front cover, engine mounts/brackets, intake/carb assembly, etc..correct? I appreciate the knowledgable answers and hope I can someday assist you guys with your Toyota's.

If you are staying carbed, yes. If you have an S4 block, I don't know if there is any difference between the 2 series in the bolt locations for the intake though.

 

86 block manifold bolt bores will be the right one? I know I maybe be asking an unancerable question w/out you here to see it. but, if there is a casting number or something on my block I can provide you, let me know I'll get it. Thanks

 

Oh, by the way...my newbie status duty.

 

1 pic, come on now, that's like getting flashed with only 1 boob, lol. I'm not sure what the difference is, but the intake maifold gaskets for the S4 and S5 are different part #s.

 

I will try to get more tomarrow or soon after one of the porters details it for me

 

Okay I was in a rush earlier, but now I have time. It's not your oil control rings. If it was the control rings you would be brining oil. the control rings keep the oil out of the cumbustion chamber they don't seal any of the cumbustion gases. If you're getting smoke out of a breather near the oil filler neck or on the filler neck you are getting combustion gasses blowing by into the sump or "crank case" in boinger terms. This is happening cause of a bad side or corner seal. Lucas will do nothing to fix this problem. If your problem was oil on start up or deceleration then you'd be having a oil control seal problem, but that's not what you said. So, therefore I conclude that you either have a stuck or bad side or corner seal. Here are your options. since tey put 50w in the gas it's going to build up huge amounts of carbon inside and this might be causeing yout side seal or corner seal to freeze and allow cumbustion gases to enter the sump and vent out the breather. My suggestion is burn throught that tank of gas as fast as you can then get two bottles of seafoam. after you get that bad gas out put in 1/4 tank with some 2 stroke and a whole bottle of seafoam. The drive the hell out of it. It's going to smoke like a bat out of hell, but it's going to kill all that carbon buildup the 50w caused. Then after that 1/4 tank is goine fill up with a god low sulfer gas (Chevron, Shell or 76). Then set your idle to 3000 rpm and find a vaccume source and shove the hose in the secone can of sea foam. Someone might call the fire dept from all the smoke, but at least you'll know it works. Or, you can just rebuild it.

 

Well, yesterday I mixed 4 gallons of fuel/4 oz 2cycle and I could see no more visible smoke. Supposidly they only put two gallons in when they had the 50wt in there. I do not plan to rebuild for a while. I am going to seafoam it and add Lucas once work here at the shop slows down. Thanks for your input. How bad are these things to rebuild anyways? I could easily find a less-than-20k mi motor for less than a rebuild, but I am curious.

I had seen the car run before the engine oil was dumped in the gas and the breather did not smoke. Hopefully that is why it was and a rebuild is not neccessary now that it has the proper mix.

 

I had to read Hyper's post a couple of times, but he makes good points on the side and corner seals. I would be suprised if the 50 wt. oil is the total cause of the problem, it probably exacerbated an exisisting condition. Seafoam it, it won't hurt and will claean out the carbon.

In all honesty, I don't think you have a major problem right now as long as the compresion is good. If you want to irritate your rotary doubting coworkers, perform the vacuum induced Seafoam treatment in the shop. lol Then take it out for a good hard drive.

 

Hey Ray;
Here is a Brain Fart for Ya.!
Before you spend any $$$ or time on this Babe.
(Drive the car for awhile) ie 500miles in a Combo of Street and City Driving.
Try not to Shift Below 4000RPM and Redline or Buzzer Shift It like getting on to Freeway like OnRamps.
Another words you will be cleaning out all the Crud and Carbon Build-Up that might be left over from Previous Owner.

As far as the Carbon, Looking at the Mods I Doupt there is much. But you have to ask yourself *Self* How many Peoples test drove it before you bought it that had no clue that you have to Drive it Like you Stole it once in awhile?
And of Course adding 50wt to the Gas Tank did not help much!

The way that I'm reading your Progression so far it sounds like the more you drive it the better the car runs. Another words drive her more before the almighty $$$ gets out of hand.
Thats why we own a Rotary isn't it?
Just some Sat Morning Thoughts!

I've owned 6 RX-7's and they started out Stock. You got real lucky on this $900 purchase. We will get the bugs out of her (Just Have Alittle Patience) or Part it out and Triple your investment.
Merry Christmas

Part it out?! I'll take what he is smoking

 

correct me if im wrong but the gsl had a wiper in the rear hatch window didn't it? from the picture of that i would say that your car looks like a GS and not a GSL. nice looking car though, i bet she screams if you open her up

 

Don't know, maybe somoene can answer that for me. Maybe it is, or maybe it's a GSL-SE that had them. Either way it doesn't matter to me because it wont see the rain any time soon!!

:::EDIT::: Vehicle does have 4-disk brake. If that helps in any way to determine the model. 4-disk brake I also assume it is a LSD that came in the vehicle. Hopefully no one trys to tell me how to check for a LSD in a differential, as that would be quite insulting. Thanks.

4 disc means it has an LSD and you have a GSL or a GSL-SE, but your car is 4x110 wheels so it's not an SE. And your car did have a rear wiper. see those black pugs on the window those are the mounts for the wiper. Cars that didn't have a rear wiper (S and GS) Did not even have holes in the rear window. So don't listen to the newb it's a GSL...
