I have EB Mod V Spec with 7 1/2 gallons on it and still running strong. I have sealed backplate, carb, and pinch bolt, the only issue I've had from time to t ime, is having to replace the dust cover on the LSN, you have to inspect it on a regular bassis, cause with time you will get some tiny holes that will throw your tune way off, and worst case is that it might suck some dirt. At fist I was hesitant to get an OS after all the horror stories, not lasting more than two gallons, but after owning one, I'm very pleased, to the point that I'm ordering a new p/s & rod for it.
When you take it apart do not use WD-40, use some good quality AFR oil to lube it up. As far as engine sealant I use Lucky 7 very good quality.
