1984 GSL SE no compression.
 

Hey there. Been out of the rotary loop for awhile now. I have aquired a GSL SE with 40,000km on it. Hasn't ran since 87 and is absolutely immaculate. It won't run. Obviously fuel system etc needs to be gone through but my main question is this. It has 150psi compression on front rotor housing and 0 in the rear housing. Now is there anything that can be done to repair the compression without a full rebuild? The last time it was ran was ten years ago. I know it hasnt blown a seal. I don't want to rip this car apart since it has been heated garage kept for 30 years and should be in a museum but if I have to I will? I've heard atf tricks etc etc but there are lots of pros and cons to this as well. Any info or advice would be muchly appreciated. Thanks.

You can try soaking the bad rotor chamber with seafoam or PBBlater (or similar) and hope it's a stuck seal. You can also remove the exhaust manifold and see if the seals have any deflection. Let it soak a couple of days, clean out the fuel system, and give it a go.

Awesome thank you for the advice. :)
