engine seized up due to low oil because of a major oil leak that i found, anyways got if freed up right away actually without problem, no struggling no nothing, um did a compression test to see where i was at and its not good at all it went something like this.....0,45,0,60, any ideas what exactly is in need here?
 
i would try honing the cylinders, new rings and a head gasket. if there are two cylinders next to ecah other that are low or no compression it would be head gasket but since all oare low or none i would start with the rings and gasket.

let use know whats up.

while your there check your oil pump clearances, you dont want that to happen again.
 
yea i would say hone also. but i would look at you rings too. if they messed up the cylinder walls to much you may as well bore it out. but yes def new rings. i woud take a look at the head also. you may have some bent valves or missed timming with no compression
 
plastigage you crank bearings to spec. thats how you will may sure your oil pressure will be correct.
 
ill keep you guys posted, i gotta pull it in and rip it apart, i was just thinking of buying a new motor all together LOL, i didnt miss timing at all everything was still PERFECTLY lined up after it happened because it was the first thing that came to mind was a jumped timing! LOL
