hello all. i have an s5 turbo engine that had been stored resting on the fly wheel for several months. i am just curious as to whether or not this could have caused any damage to the thrust plate or any other components.
as always, much appreciated

 

No worries at all as long as it wasn't dropped or anything.

You should however be worried about the apex, side, and corner seals being stuck from sitting for so long, unturned, and without any internal lubrication prior to storage. Even if they had lubricated the internals, it would all have drained away toward the rear of each chamber due to gravity, leaving 3 side, 3 corner, and 3 apex seals dry and potentially able to stick.

 

thank you for the reply, and reassurance. i have turned the motor frequently. should i maybe pour a little engine oil into the intake ports and turn the motor to work it into the seals?

 

Sure, it won't hurt, but it might not undo anything that has been done over the past few months. On the other hand, it could be completely fine regardless. I have seen too many perfectly good rotary engines ruined because of storage, though, so I am a pessimist with regard to that.

 

yeah it is/was a really good engine. all the compression strokes sounded nice and even. could feel detent behind all the apex seals when felt through the exhaust ports. man, i really need to get this back in the hole then. paid too much for this engine to turn out to be a core
thank you again for your response

 

if it pulses still you should be fine, but adding 2 stroke oil or MMO would be good insurance.

even if the seals do wind up sticking you can usually prime the engine with enough oil to get it running to loosen up the seals, either via enough cranking and deflooding or a good pull start followed up with a decarb.
