New member, new project, siezed engine
 
I recently purchased an '87 turbo that had been sitting for several years with out being started. The car was parked because it needed exhaust work and the guy (a friend of mine from Church) never got the money to get it fixed. It has 77K on it and the rest of the car is in excellent condition. I have pulled the plugs and added MMO but have not been successful getting the engine to move. Should I try to get some oil into the intake so that more of the rotors will have oil? Has anyone had similar experience? I am thinking of pulling the engine and tearing it down to see if it is worth rebuilding. However, if I want to use it as a core, most places say that the engine must not be taken apart. What is the list wisdom on this? Is the chance of it being a simple rebuild good or remote?
Thanks for any help.

With that low of miles, I'd just try to unlock it and go from there. :)

DO a search for "carbon lock"

Update. I had done a search on carbon lock and that is what led me to using the MMO. I removed the fan so that I could get better access to the front of the engine with the intent of making something to attach to the pulley so that I could put more torque on the eccentric shaft. I had read that torquing on the bolt would result in over tightning but I decided to give it a try anyway. After a few minutes of working it in both directions the shaft started to turn and it is now turning to the point that I intend to squirt in more MMO as I rotate the engne and then let it set for a few days before I attempt to start it. I also intend to drain the gas from the tank and replace it with fresh gas.
I'm excited now, I was having visions of an expensive rebuild or replacement and was wondering if it was worth it. It also looks like I am going to have to replace the entire exhaust sytem due to rust but I will wait to hear the engine run before taking it apart and seeing if I can salvage the cats.
Thanks for the replies, this looks like an excellent forum with many experienced listers. I owned an RX-2 back in the early seventies and look forward to the rotary experience again! I'll keep you posted.

Drain the oil and throw some new mineral oil in it.
