I overheated my TII, and babied it home the other day with the temp gauge pegged. I managed to crack the plastic top, but have fixed the crack, bought a 180 thermostat and gastket, and filled it with rad flush. now the car won't start at all, it just turns over. I pulled the plugs and checked them and there's no coolant on them either. the hoses are new and the water pump seems to work fine. any ideas as to what I did to my car?

 

you overheated it. (simply put)

when your car cranks, give it some gas. it's gonna be really hard to start but eventually it will. when it does check for smoke (white) that will be coolant burning. if that's the case, you cooked your coolant seals and they are now shot. rebuild time.

a very easy way to check if your coolant seals are shot, is in the FAQ

 

I'm willing to bet the motors shot. If you didn't cook the seals, you might have warped the housings. Just keep trying to start and see if it leaks coolant in the engine.

 

I can't even get the car to crank, it'll turn over but it wont start for anything

 

I see no way that you didn't do damage.

 

Like it or not it's time for a rebuild. Think of it as a good thing. You get to port and you'll have a refreshed engine!

 

yeah I know, as much as I want to, I really don't have the money to rebuild right now, kinda wasn't plannin on it. What should I do while the engine is apart? I want to port it and upgrade to 3mm seals, but what should I have to use 3mm seals? I only want a street port, but I'll keep the stock turbo.

 

3mm is overkill for what you want. The stock mazda seals will do just fine with the stock turbo and a streetport. 3mm really for engines running really high boost and putting down alot of power. Alot of people are running 400+ hp on the stock seals and holding just fine.

 

you wont need the 3mm seals if your not going to modify it heavily.

any luck with starting it? have you pulled the fuse and checked to see if you coolant seal is gone?

 

I'm not sure how to check for coolant seals, but I pulled the plugs after trying to start it again and they were covered in gas.. I don't think that's a good thing. it just turns over but acts like it's not sparking though. I pulled a plug and left it in the plug wire and they are firing so idk.

 

it's probaly flooded right now. pull the EGI fuse and open your rad cap. crank the motor. if your coolant starts to bubble up and pour from the fill neck, then your seals are probaly shot. do you have an S5 or S4?

 

s4, it's an 87... where's the fuse at?

 

your fuse box is right next to the drivers side strut tower.

cranking w/o the EGI fuse will help you out too, if your motor is flooded

 

I'll give it a try

 

I pulled the fuse and tried crankin it, and nothing happened.. bu there are no bubbles. what should I do now?

 

how long did u crank it for and did u hold the gas pedal down while u were cranking it w/ the fuse out?

 

I cranked it for a while, and I tried both holdin the pedal down and not touchin it. I just sits there and spins

 

I guess I'm gonna have to pull the motor and rebuild it. any idea how quick I can get it done? I was lookin at the kit from Atkins rotary along with the video, anything else I should consider while the motor is out? I'm on a really tight budget, so nothing outrageous.

 

my friends honda accord has got a leaking head gasket, it leaks into the combustion chamber which is the same idea as your coolant seals, we tried push starting with no luck but what got it going was some starting fluid and it fired right up. btw, my turbo II overheated to right before the "H" mark on the temp gauge, i still drove it about 1000 miles afterwards before it blew (from detonation).

 

idk it won't even fire, I'm all out of ideas... where do I use the starting fluid?

 

well i mean u can rebuild an engine in as little as one full day but thats if u have all ur tools and experience. if u wanna do it real good and take ur time then u shood take about a week IMO

 

try push starting it, and then pop the clutch

 

for some reason I don't think that's gonna work

 

I tried push startin it and it didn't work.. I have no clue what the problem is

 

check for compression, if it seems strong, poor a bit of motor oil into the engine via spark plug holes, spin around Put some BRAND new plugs in and try to fire it up. No use rebuilding it if its still good. If you have a compression checker use that instead. Also check for spark.
