while i have my motor completely torn down. with the new pistons, rods, rings, wrist pins, crankshaft. what else needs to be replace while im putting it back together go ahead and list of parts and the reason why so i can make a list of what i need to purchase next. thank you

if its an ecotec why are you replaceing the crank?? also i see nothing about building up the head..

a rod bearing went bad and tore up the crnak found a brand new one for 150. so bought it. the head is getting cleaned. but performance parts for the head are coming in later. so obviously valve cover gasket.. head gasket.. intake mani gasket header gasket. timing chain cover gasket. anything else im missing??? what do you recomend replacing whikle its torn apart,

The main bolts. they are torque to yield.

what does that mean? i was planning on buying head bolts. how much are main bolts where can i get them?

Torque to yield means they are tightened to the point that they stretch. If you reuse them they will be weaker than last time, and stretch more, increasing the risk of them snapping.

ok so new head and main bolts. but wheres the cheapest place to get some?? anything else can you guys think of that i need to replace??? i heard about replacing the rear main seal.... do i need to replace that??
