My friend has an 87 TII. It hasn't ran right for some time. He had it at a local mechanic's shop, where he was told that the problem was a valve located somewhere under the turbo assembly, that lets either oil or water into the engine somewhere near the apex seals. I'm not very clear on the whole thing. I'm just now starting to research these engines to try to help him, and he's not very mechanically inclined, so what he tells me is rather vague. The mechanic told him that the rotors, apex seals, and turbo are great, and that if he can get this valve replaced, it would run right again. From what he says, it will run, drive, and pull hard, but if you try to start it again, it won't start. ( I surmise that if you wait long enough, it will.) The mechanic told him that this valve is broken off, and whichever fluid is supposed to be released from it is instead leaking out. This mechanic also said he didn't know where to get another one. The car is now at my buddies house, and I'm going to try to fix it for him as soon as I can get more info. Please Help!!!!SOS SOS SOS SOS SOS SOS

I sugest you go to another mechanic. if he says a part is pad and doesn't know where to get another, then odds are he doesn't know what that part is or how is it suposed to work. go to a mechanic that is rotor friendly preferrably one that builds performanc motors for the rx7. these are the only type of guys I trust to work on my car. I have had many unpleasant experiences with the other type. don't trust them. not even the dealer.

the oil metering pump??? if that's not working don't drive the car!

but that wouldn't give the car a inconsistant starting problem. also if that was causing the engine to run bad. I'd say the engine was already dead. but you say the apex seals are good (which I would assume compression.

if the oil metering pump is bad. you can run 2 stock oil in the gas. stick around 1/2 quart of 2 stock oil in with every tank of gas. that will make it safe to drive.

try and find some more info on what it was.

My guess is just one of the oil injectors is broken. Go to this site and look at the lubrication section. Its a factory service manual for 88's. Look for oil injectors. Shows how to check them out. And yeah, I know the turbo assy is'nt under the intercooler but the thing is so vague I thought I'd just take a shot at just one of the injectors.The oil metering pump is also shown in the above manual. Have the mechanic put his finger on the area that is suspect. With the above manual you should be able to locate the oil metering pump on the forward right hand side of the engine. It should have four small lines coming out of it going up towards the top of the engine. There should also be a thin rid connected to a lever on the pump. The other end of that rod should connect to the throttle lever, and it should move when the throttle is depressed. Take a look at the above book and you should be able to figure it out. http://www.iluvmyrx7.com/Technical_I...ice_manual.htm Your friend needs to download that manual to his hard drive.

I'd go with hailers on this one, the OMP is at the front of the engine, so that (location description) hopefully narrows that out of possiblilities. Could the lines to the turbo be leaking oil?

1) I would run away from these idiots.

2) No valve carrying oil or water/coolant would prevent the car from running right (unless the engine is dead right now ).

3) If it's the oil metering pump "valve" that's leaking, it will not cause the engine to run badly.

The mechanic in question is the only supposed rx-7 tuner in the area. I don't plan on letting him near the car again, as he had it for a month and a half, and this rather vague info was all I could get. In the next couple of days, I'm going to start tearing into it. I'll probably start by looking at the area beneath the turbo for a leak, and hopefully be able to give a better description of the problem w/in a few days. Thanks for all the help, everyone, and I'll probably be back for more advice when I know better what to ask. I'm really just a backyard mechanic who digs in and tries to figure things out. I'm usually successful, because I solicit info from people like ya'll who know more and are willing to help.

i could be totally off the mark here but is it possible that he could be absolutely wrong ?? Im no expert but from what your saying, I just think it has leaky injectors.. That would explain why after youve been driving hard it wont start up a couple hours later.... ? Try pulling out the egi fuse next time it wont start, and crank it while holding the gas pedal to the floor. Then put the fuse back in and crank it, does it start right away ??

NCsublime

Yeah, I have to agree with fuzzi. I was going to ask you what it sounded like when you try to start it up. Does it turn over at all? Give us some detail on that. But I'd have to agree, pull your egi fuse and crank the engine a bit. Then plug it back in and try to start it up again. If this works, there should be a strong fuel smell and a little extra smoke upon startup. Good Luck

BTW, Rotary Performance is in Garland. I'm not from Texas, so I have no idea how far that is from El Paso. Maybe not close enough. I've never done business with them personally, but I hear they have a good rep.

I'm a little embarassed at my reply to this. I think I just got so caught up in where he says some valve is broken off that I was fixated on finding out what was broken off. Gotta agree that if you broke a nipple off the injector or whacked the hell out of the omp it should'nt affect the performance. Thats a pretty simple omp on the 87, unlike the later ones. It would help to tell us what you mean by the car has not been running just right. Please? We can do better if you give us another chance.

You guys have been a great help so far. I haven't even heard it run myself, I'm just going off of what he's told me, which is rather vague. I'm in the Army, have two kids, and a part time job, so I haven't had a chance to look at the car myself yet. I will be looking at it by Sat., and posting again. Not being at all familiar with rotary engines, I've just been trying to get as much info as possible, until I get a chance to look at the car, so I'll know a little better what I'm looking for. After looking at the manual ya'll gave me a link to, I have a little better idea what I'm going to be looking at, as well as a couple of possibles as to the problem. I will be posting again as I value the input of people who know more than I about a certain vehicle than I do. Thanks again.
