So I bought this 97 challenger 1800 a little over a month ago knowing I had to do a top end rebuild on one of the engines but as I’m tinkering around in the engine compartment this past week I notice one of the oil lines coming out of the oil tank is clamped off. I’m new to the Rotax engines but I’m told this is not a good sign. Most likely it’s my rotary valve seals leaking. My question is do I unclamp and see what happens or do I leave it clamped? If I leave it clamped for the season what damage is it going to do to my engine or is the damage already done and at this point I’m just waiting for a failure?
