Stuck apex seal...
 

Hey guys a bought an JDM s5 from some dealer in Canada. wen i got the engine it had no compressions on the rear rotor, and one puff on the front. some mastery oil and i got 3 solid puffs on the front and 2 on the rear. I pull the turbo out and all apex seals are intact but one on the rear is stuck on the rotor grub i tried pick, oil, turning the engine with the starter, magnet LOL and yes there is a ton of carbon built up. Before a send it back you have Any suggestions thanks.


ps S5 JDM on a S4 I am in for it...:scratch:

Try soaking the inside of the engine with ATF or oil. That might help. I would advise you to just go ahead and tear the engine apart. Buy a gasket set, 3rd gen corner seal springs. and replace the apex seals with 2 piece seals. That way you do not have to worry about it. That will also give you the oppertunity to inspect and/or replace the rotor bearings and stationary bearings. I have only heard of a very few people getting a JDM engine without having to rebuild them. Not trying to scare you, but trying to advise.
