Problems BIG PROBLEMS
well last night my SE started to overheat as said in this thread the last entry that i put on it https://www.rx7club.com/1st-generation-specific-1979-1985-18/update-overheating-499219/. later after i got her home i tried to start her up but no dice. so i went back out there and i deflooded the eng there was alot of fuel in there and what else did i see this green stuff, yup coolant ***. and now i cant get her started at all she keeps flooding. i must have deflooded at least 5 or 6 times. she wont start and its starting to **** me off i know that im going to need a rebuilt but i would like to get her started so that i can try the block weld trick on the water seals. does anyone have any ideas to help out pls?

hmmmm....sounds like you blew a water seal good enough that you might not be able to get her to start at all...but definately just change the plugs like mentioned...cleaning isnt worth it...if you REALLY want to get it started...pull start it...
sorry to hear about your bad luck...anywho....its pretty damned near impossible to find a soft seal kit "cheap" anymore...'specially for an -se man...

If you overheated the engine, there is a possibility that you warped one of the housings. I really can't see how you could blow out a coolant seal. Its basically a large O ring that seats into a grove on the end plates. They are wedged in there pretty good. I'd be willing to bet that you warped either the front, intermediate, or rear plate. If this is the case, you'll have to buy another plate, which could be hard to find for an SE engine.

its just the front rotor housing the had coolant in it. i guess i would have to tear it down to find out whats warped i could call atlantarx7 and see if he's got what i need and go from there. or just order a new engine from rx7world.com and go from there also

thats what i was thinkin too. i heard that you can blow a seal and i also heard the that you can warp too but i dont see how that i can the housing or a plate if i didnt get the eng up past 200 degrees. i dont know. im going to try the block weld trick and see if that works and if not i try a rebuild.

^hey...its all good...but ive torn down plenty of engines and know that the o-rings are usually pathetically weak if still in tact...but usually the first cause is gonna be the o-ring ![Big Grin](https://www.rx7club.com/images/smilies/biggrin.gif)
