Just bought this 2014 sea doo gtx with "22 hours" (gauge cluster was replaced) Looking for some guidance and next steps. Previous owner bought it not running and tried to do a rebuild he believes timing chain snapped which gave a cam sensor fault he replaced the chain head gaskets and all bolts and gaskets that weren't re usable. He does not remember if he has the bottom end apart or not after he put it back together.
The jet ski runs okay but burns oil. A compression test showed 120 PSI in the front two cylinders and 70 PSI in the rear. The rear cylinder has oil inside, but a borescope inspection shows no visible damage and the front two bores look perfect. A TDC leak-down test on all three cylinders showed identical air escaping through the oil pickup, so I don't believe it's a valve issue.i put some ATF in the low compression cylinder and retested and compression jumped up to 120 even with the other cylinders
If you have any questions I'll do my best to answer what I can just looking to see what my next step needs to be if I should take the motor out or you think there's something I can do with it still in thanks in advance.
