Hey everyone. I am sort of new to the FD world, been a member for about 3 years but haven't really been a forum surfer for too long. i currently have a 1993 MB FD and i bought it stock with high miles from an old lady back in 2007. after i purchased it i had no problems whatsoever. i came from a highly modded WRX and thought to do the same with this car but failed. I put on the car RX7STORE.net stage 2 package and really liked it. After a few weeks the car started acting funny. honestly I put full synthetic mobil1 and i know now that was a bad idea.some of the problems were that it would overheat and i would have to fill the coolant up almost everyday. cold the car would start right up but if i turned the car off and tried to start it half hour or even 5 min later it wouldn't. the car at high rpms would shoot out a cloud of white smoke and smelled of coolant. I still don't know what the problem fully is( water seal?), my mechanic said with a jerry rigged compression test that the front was 65 and rear was 80 so he wants me to buy a new engine and put it in but I'm skeptical about it. could someone point me in the right direction. i wouldn't mind doing a rebuild. all i really want is for the engine to produce enough power to be reliable and last 20 miles a day for a couple years to come. thanks

 

Sounds like a coolant seal failure.

 

What would that entail to be fixed? Where I'm located there are no rotary mechanics for 100+ miles and I don't trust the local dealership one bit. There price estimate was 12k

 

coolant seal failure would mean engine rebuild and the cost of rebuild will vary depending on whats reusable

 

12K for a rebuild? trollolololol.
Either do it yourself, nice workshop manuals and books + videos out there available, or send it to a rotary mech. plenty of em here on the forum.
To give you a reference of the top of my head:

Coolant seal rebuilds are usually not that bad. Pretty much all of the expensive stuff should be reusable.

 

Depends on the actual failure, if it is the coolant seal and you have not overheated the engine repeatedly then it should be a straight rebuild. However if the coolant seal retaining wall(s) collapsed, then there are additional costs. Regardless it will not cost $12K, even if you shipped the entire car out to us, it would not cost half of that. If you are able to pull your engine and re-install it, you can have it rebuilt by any number of places.

 

Mybe overheated 10 times but always pulled over and would let it cool down for 10 min.

 

when you say overheated 10 times, what water temps have you reached?

 

gosh its been 3 years, but i think the highest ever was maybe +-3 so around 109c.
