well i swapped the oil pan, needed a new one anyway but it still leaks. i'm thinking it may still be coming from the cooling lines, i noticed a little bit of fluid around them the other day. and it's more of a drip now so there's not a lot of fluid loss. could i use some type of thread sealer on the cooling lines?

 

wrap them with sealant tape. I usually do it on all metal fittings.

 

tape won't help anything of flare fittings. they should seal aginst the flare. tape may help o nthe fitting that goes into the trans case. did you level out the dimples around the bolt holes in the pan? o ring on fill tube good?
