Re: Difference between Jasper engines and rebuilt-jeep-engines
if you end up getting a remanufactured engine go with grooms... i
replaced mine with one of their 4.0's... runs like a champ. everyone i've talked to has had good experiences with them. plus $90 gets you a lifetime warranty. a bit pricey but worth it i think. http://www.groomsengines.com/g-catalog.html#AMC |

Re: Difference between Jasper engines and rebuilt-jeep-engines
Y'know, I almost deleted that part cuz I got to thinking
about it and I guess I really don't know. It could mean that the rings are a little sluggishdue to having gunk all over them (sticky gunk!) Or it could mean that a valve has an area where it doesn't seal well, but if it's a bit loose in the guide, maybe it seals sometimes. Good question - I have no definite answer, but for some reason I always count the revolutions and compare. If you run into that and then end up taking the head off, see if you can identify a possible cause. Maybe somebody else has the right answer? I wonder what the actual compression is in PSI while the engine is running with the pistons doing 100 strokes a second! I used to run single ring pistons with the ring "L" shaped and right at the top of the piston, so the pressure caused the "L" to rock outward and seal even better. Very poor compression at cranking speed but it sealed better than anything else at 12,000rpm (yeah, a small 2-stroke!)
