well i rebuilt my ka pretty much everything is new crank rods pistons timing kit every but a oil pump i have both top guides removed. i only get a rattle around 2200 rpm it goes away any higher or lower than that but its loud
so i took the top timing cover off the chain is tight and tesioner is working fine
but the lower chain is really loose i can see the tesioner and guide if i pry on the guide the tensioner will pop out but the guide is really stiff is there any way i could have forgot an oil seal on the tensioner or maybe tightened the guide to much i torqued al the timing parts to fsm standards

how many miles since rebuild? What brand chain did you use? Plastic guides, or plastic coated metal?

well, looks to me like you might have to tear it down and inspect it. If that chain breaks, you risk putting a hole in the front cover. Be Safe

i'm going to on saturday. I dont really think i forgot anything, but theres always a possibility. so do u know if that lower tensioner guide is supposed to be that tight.

I found something i missed putting in i didint install the timing cover o ring. Would that maybe cause lower oil pressure to not pump the tensioner up enough?
