ok well i got this motor thats been siting for like half a year and i was worndering if its worth puting in beacuse today i was spining the motor by the flywheel and i saw some water come from the housings it was like a rusted color i dk know if it got water in it or somthing how can i check if its any good like commpresion or see if the apex seals are anygood

Get a standard piston compression checker, and remove the schrader (sp?) valve. Next, put it in the leading [(l)eading=(l)ower] spark plug hole and spin away! Look for 3 even bounces, all above 95 or so. Repeat for the other rotor.



Depending on how well it was prepped for storage, it either got wet or has a popped coolant seal. If its a coolant seal, its rebuild time. If I saw rusty water coming out of an engine, I'd probably rebuild it anyway. Sounds like it got nasty.

all right thanks for the info im pretty sure its goign to help me out thanks

ok well i was looking in the motor thro the exsuat and i was looking at it and it looks like it got rain water in it like trow the intake or somthing but all the water is out of the motor but theres that oragne **** still like in it if the compresion is good should i put it in the car ?

make sure the compression is good first. might wanna spray some oil in there. iron seals iron rotor = bad....

ok so if the compresion is good then all i should do is put some oil and spin the motor a few times and i should be good

yep

use MMO if you can, make sure if youre storing an engine you plug it up properly not just pull it and leave it outside lol (i know you didnt do this but you should smack the person who did) might want to check the intake runners and other various openings into the motor for other things like debris, wouldnt want to start a motor with a screw in there or have a ton of dirt dropped in from the intake mani.

yea im pretty sure the water went threw the intake yea i should give the guy a nice back hand for it tho lol were can i get MMO... thanks for all the info

marvel mystery oil is a godsend and im not sure where youre at but you can find it at oreileys auto parts and probably any other parts stores although ive read some forum members are noticing it being sold less and less in some areas. it would be in the same area as the oil/fuel additives
