i just bought an 85 rx-7...it runs but it smokes and when i try to drive it stalls even when im at 5000rpm and try to go it stalls....does anyone else know anything about this problem cuz its really slowing me down i need this car a 3 weeks and i just cant get it goin...any info would be great!

more info on this problem of yours please

time for a rebuild maybe? did u check compression when u bought it?

white smoke means coolant .........bad news rebuild time

grayish smokes means fuel........maybe tweek carb or carb rebuild

black smokes means...........oil burning and might be rebuild time



compression check numbers for each face?

coolant system check?

well im not sure whats wrong like i start the car up with the choke and the choke stays on for quite a while and it doesnt smoke to much but when i rev it, its terrible! and when i try to drive it stalls....My temp is like right in the middle of the guage like between hot n cold so i dont know if thats normal or what and when u open the hood u can feel the heat comin off the engine like crazy and the oil filter is really hot and this is running it for about 5 min.......so any more info would be great!

no cookie for that bit of info man...





oil burns BLUE! Unburn fuel is black...I guess you could call it "grey"...coolant is white...water is steamy.....



Checking compression is key in any engine diagnosis.

so how do you check compression?

This is from an earlier thread, it explains very well how to check compression

using two different methods.

Just so you get the message, Im posting this in all three places you asked:



Sounds like a blown water seal to me. Check your coolant level in the radiator. If its low, fill it and then try and drive it or run it for a while and see if it goes down again. If so, its most likely a bad water seal.
