Just a note: The compression is really low right now as you stated that it spins like a bandit, so maybe some oil injected in the engine isn't such a bad idea. I have not had to do that in years and it was on a worn out 82 which was easy to lubricate by just pouring a couple of ounces in the carb intake. I don't want to come off negative about putting some lube in the intake and I suppose atf would do the same thing. I just prefer regular motor oil. If I had to do it on a turbo I'd pull the intercooler and pour a half cup in the duct just prior to the throttle intake and spin the engine, put it back together and spray the starter fluid in the filter assy and have a go at it again.

Yeah. Gonna smoke a good bit when it starts, burning of all that oil that's goning to get in the exaust.

Darn I thought I'd given up on this. Maybe if that does not work......bring in pop's mechanic.

Do all that mentioned above. But if youve been crankign her with the fuel pump turned off for a while, makes sure you turn the pump on, the car wont start without any fuel. I would pour some oil or atf through a plug hole and try to start it for maybe 2 seconds with the fuel pump off and then flick the switch to on while still cranking.

Grab a phone book and see if 'Pruven Performance' is anywhere near you. It's supposedly in/near Conneticut.

Another option for ya:

I have heard of pruven performance actually, my best friend was having them build up his wrx to be the fastest in the nation (kid is LOADED) but that was before he was trying to prove to me how awd has better handling, passing a car around a curve at 85, flipping it and damn near killing me. However I was not aware that they had any rotary knowledge or that they had a T2. (note to readers I do not drive like that I was scared )

I will keep all my options open as soon as I try getting some oil in there to build compression.

I didn't think about trying to get it into the intercooler duct, I am assuming the one going to the throttle body correct? I would have guessed the oil wouldn't want to get pulled through there all the way to the engine??

I have been trying to fit all the funnels I have to the lower spark plugs (and upper for that matter) and don't know how you guys get anything in there! lol, Is there some obvious trick I am missing?

I know I have said this reduntantly but once again I want to express my thanks to everyone. I must say in all honesty one of the biggest joys of having an RX-7 is having the forum community to go to for help. I see all my friends with their cars try to figure out this and that and they can never find any good info. I don't know what I'd do without you guys! So once again thank you forum members!

***I didn't think about trying to get it into the intercooler duct, I am assuming the one going to the throttle body correct? I would have guessed the oil wouldn't want to get pulled through there all the way to the engine?? *******

Beats the bejezzus out of trying to pour oil into a spark plug hole. And it will go all the way to the rotors and to the exaust pipe.

Another way would be to attach a oil supply to the large vac hose at he back of the throttle body and spin the engine. That hose leads to the oil injectors and the oil in the hose will be sucked into the rotor on its intake stroke. Hypertenz I believe has used this method to oil the rotors.

More than one way to skin a horse. Pouring into the intercooler duct at the throttle body sounded so much less of a mess and less time consuming. Before I get ragged on.........I have not a thing against putting the oil in the sparkplug holes if that is your prefered method. Just seems a bit of a pain in the ........

iluvrx7z

Well I just tried the intercooler duct, I wasn't trying to rag on ya, just asking

It didn't seem to want to vroom then either.

I put about half a quart of 10W30 (which is all I had available) sprayed some starter fluid and went for it.

It didn't seem to spin any slower. I had my old man put his finger next to a spark plug hole, just checked the rear rotor, and he said it gave even swooshes...

Is half a quart enough oil? I'm wondering if now that I have more oil in the engine, and new spark plugs, if I should try having the car towed around the neighborhood again...or if its a mute point. Also if I do have it towed, what would be a fair distance before calling it quits...

Last question I promise lol, when I am having it towed, what is the best procedure? ie which gear, what kind of clutch/gas/ignition action?

Thanks

Dan

HAILERS

I'd would have thought a half cup would be enough.

Before you tow it, clean the sparkplugs and reinstall. I'd say if you tow it, put the ignition to on, have the lead car get you up to twenty to thirty mph, and then put the car in second or third and eaaaaaze the clutch out(so you don't pull his bumper off) and with the clutch all the way out, let him pull you for a couple of blocks. If you get no action at all, shove it back in the driveway and get your pops friend to have a go at it.

Make sure that your fuel pump switch is to the on position before pulling the car, the battery should have a semi decent charge also (just about anything but flat dead).

When it starts its going to smoke a lot for a good half hour. There will be a lot of unburned oil in the exaust, and it won't burn off completly until the exaust gets good and hot.

You've got a mystery car there. The car ran at one time and the timing hasn't been fooled with. Heck. Pull it four blocks before giving up.

iluvrx7z

Lol, mystery is about right. I have gone and looked over all the connections I made and everything I touched and I am just baffled.

When I first put it all back together it did not wanna start at all, then not even 50feet from my house it roared to life...since then I was able to get it to start quite a few times in my garage. I was shocked when I pulled it around the second time and it didn't work, thats when I started getting nervous.

When I first did it I followed in third, with the ignition on, then just for nothing decided to touch the gas pedal and it fired up, very weird, I tried repeating this to no avail.

I'll see if I can get another tow rope (had to return the one I used) so I can give it another whirl, I'll post back with the results.

Good luck!

iluvrx7z

YES!!!!!!!! YES!!!!!!!!!!

Sorry, I am just really psyched right now. I finally got it started!

Guess what lol, I thought and thought and thought, and then I dunno why but I didn't trust the fuel cut switch I used so I disconnected it and just connected the wires together and vroom!!!!!!

I nearly had a heart attack. So I must say thank you to EVERYONE who helped out and to Amtr, you were completely right not to ruel out fuel

Thank you for everyone for going out of your way to help me out, only real problem I have is that DAMN EXHAUST LEAK that I thought was all fixed!

Maybe everything isn't tight enough but I tightened as much as I could...any help there?

Thanks once again!

Dan

ps. this was after I convinced my old man to pull me around, it not starting, and him cussing me out and telling me the car will never work again! HA

Amur_

Congratulations!

Exhaust leak. Is it coming from a gasket? Do you keep blowing gaskets out?

If so, those goddamn flanges, the stock ones anyway, tend to warp away from one another over time. Don't ask to explain it - some else wrote something about it. It's happened to me, too, anyway. You've got two choices (other than continue replacing gaskets.)

A) grind down the face of each flange where the leak is (this is what I did.)

B) replace the flange with something sturdier. I don't know what - I don't remember what the guy did but he used some kind of funky metal. It sounded expensive.

iluvrx7z

I don't think I keep blowing them since they are new here is the scenario:

The exhaust comes out as soon as the engine starts, and I mean its seems like ALL the exhaust comes out lol.

When this first happened I took time to further investigate and I realized I was COMPLETELY missing the turbo to manifold gasket, D'OH! Don't know how that slipped by, but I bought a new one and replaced it.

The manifold to engine gasket I know for a fact is there and the turbo to dp gasket is there. I figure something has to not be tight enough but what???

Its a lot of exhaust...When I put the turbo on I made sure to tighten the nuts as much as I could using hand tools, I don't think any power tools would fit anyway, but they are really in an akward location to get them really tight, but I am just amazed at the volume of the exhaust, tomorrow when there is more light I will go back under the ride and see if I can tighten them even more....I don't know where to pin point it though because to my eye, everything seems ok...

I don't think I have the flanges problem since I never had that before the new turbo nor has the car ran enough to even get warm.

I'm once again stumped...

Use a torque wrench on that stuff. Also, lub up the studs with anti sieze so you get consistant torque.

Cant get a socket in there? Pick up some metric "Crowsfeet". That will do the trick.

You really should use a torque wrench and follow man. settings.

Good luck!

James

iluvrx7z

Torque wrench is a very good idea Never heard of crowsfeet though, I looked up some pics and they seem fun lol...I love tools.

I know my neighbor has a torque wrench, I'll see if I can borrow it tomorrow.

Hopefully get those nuts on even tighter if they need it, I am just amazed at the sheer volume of exhaust...weird

Your post has left me kind of mixed up.

You're saying that the exhaust is loud as hell, yet you also seem to be saying that you think that the turbo is the source of the noise.

To my mind, the turbo is b4 the engine and the exhaust is after.

I know exactly ****-all about turbos. But I find it difficult to understand/believe that a leaking (vac) turbo would result in that much noise. And if the turbo did have such a huge vac leak would the car idle like ****?
I'm as much asking these things as suggesting them. Pretty much talking through my hat here.

I've always thought that a loud exhaust note = a leaking exhaust system (it's ALWAYS been that way with my NA.)

And if your flanges are coming away from one another it doesn't take long for a gasket to get blown out - as quickly as a week if your 7 gets driven daily... When looking for any kind of exhaust leak, I get down beside/under the car while it's running and slowly run my hand along the pipes.

Just trying to understand. And help.

iluvrx7z

Trust me I need all the help I can get lol. You and Hailers and everyone else has been keeping my morale up!

Well what I know is if I look down at the car when it starts before I get blinded and start coughing I see the exhaust coming out from where the turbo assembly sits.

It comes too fast to tell if its from the dp (which I don't think it is) or from the turbo to manifold joint, or the manifold to engine joint, or somewhere else...is that possible?

I haven't got a chance to get under it yet but I sure will today and see if I can spot where its coming from....

On the bright side though it seems to me that this is the last thing I have to fix before the car is streetable....although with my luck maybe I shouldn't talk so soon lol
