i'm thinking abotu buying a 1990 RX-7 but the guy said that it must have a leaking head gasket or something, is it worth it so still go ahead and buy it, is it hard to replace the head gasket? and would i have to pull the engine to replace it or can i do it in car?

 

unless it has a swapped engine. rotary's dont have heads

 

How much does he want for it?

Less than 800cad (is canada cad? lol) go for it, by leaking head gasket I have no clue what that is on a piston engine I'm sur esomeone will know what it is and know the rotary equivalent of whats wrong.

 

ya he was asking 799 but there is some body damage so i'm gona try and talk him down.
i don't know what he ment thougb with the leaking head gasket, he said he had to top up the antifrezze could he have just been messed up?

 

If you start it when it's there, and it puffs whte smoke and doesn't stop then the coolent seals will need replacement, when thats done you can just rebuild the whole engine.

If it just puffs alittle bit when first started (Mine does for a good few mins) then it should be fine, with alittle body damage and such yeah try to bring it to 700 at the most.

 

are the coolent seals hard to replace?
and is the engine hard to rebuild?
i'm new to rotory engines and rx-7's

 

I've never done it myself but if you can work on a piston engine no problem (atleast remove it) I'd say you could do it with some proper reading.

Otherwise you can have a rotary shop do it.

To replace the coolent seals the entire engine must be taken apart (not that big of a deal compared to piston engines) the coolent seals are on the housings going around, since it's already taken apart most would replace the rest of the seals.

 

Maybe it's got a 350 in it?

 

so are rotory engines easy to take apart and put back together?

 

Well considering they only got 3 moving parts on the inside, yeah. Piston engine is a hell of a lot more difficult

 

Unless you are excited to get into the rotary world, this car probably isn't for you. I would research rebuilding an engine on this forum and decide if you want that kind of commitment. There are plenty of used rx7's out there so don't feel pressure to but this one. Unless it's a turbo, $800 is not a great price for an rx7 with a blown engine that has body damage. And you can bet there will be a list of other items the car will need.

if you have never rebuilt the motor or a motor for that fact and don't have a lot of money to spend for the in case ****, don't buy it. they are not completely complicated but don't take the well since they only have 3 main moving parts they can't be that hard. im about to rebuild my motor for my first time and i know that its gonna be a challenge for me. and im going to school for mechanics. if you are gonna attempt this just do a lot of research before you start tearing into anything. i bought mine and bought a rebuilt core and ever since then i have just been researching. everyday i learn something else that will help me in my build. if you are new to rotaries just buy a rebuilt core and swap it in. probably be cheaper. check on here with rotary resurrection or rx7world.com. <two different people

 

damn you barely beat me to it

 

the car still runs and everythign thing i have to go look at it
but i really want to learn about rotory's

 

yeah the best way and most economic way is just a lot of research and save some money and buy one thats in better condition.

 

If getting down and dirty working on cars is ideal to you, hit the search button at the top right and enter some queries about remvoing and rebuilding a rotary engine.

Yeah it'll run fine with bad coolent seals for a bit, I'm guessing it smokes like normal, maybe alil more and the owner being a unexperenced rotary owner thinks its bad, try to convince him it is after hearing it run, then lower the price

 

haha
ok thanks for the advice

 

One more note: if you're buying a 7 with a blown engine, it should at least look nice.

 

the engines not blown' it still runs good
i'll go look at it and see if i should buy it
if so it'll be my first rx-7

 

is it true that if it's aa 4 bolt pattern that its just a base modle (gx) and if it's a 5 then it's a gxl?

 

and if it has a hood scoop then its a turbo?

 

it there anythign that i woudl need to know/things to look for when i go look at it to see if i'm gona buy it? like soounds smells things like that

 

Is their a intercooler mounted on top of the motor? Yes its worth it. But ofcourse were a lil biased. For 799 you cant expect much.

 

Yeah, sort of - that's how they come from the factory. Some people put those hoods on non turbos. You will need to take a look under the hood to make sure.

I would definately check out Aaron Cake's site on How To Buy halfway down the page.

ok thanks that helps a lot
