New engine leaking oil from front case?And from t-case?WTF

[empie1]

My bothers car is starting to be a pia.Finally start it up and oil looks to be steadily dripping from the pump cover/filter housing area.Everything is torqued down, and this is a BRAND NEW long block, built by overbore..wtf could be wrong?Also, we installed a brand new (not rebuilt) oem transfer case, only to find it still leaks fluid at the drive shaft input??Why?

Transfer case was more then likely caused by not installing the shaft correctly and breaking the seal. Also when you installed the oil filter did you put the gasket on? I know it sounds stupid but Ive known people that forgot or it fell off while installing it.

Im pretty sure there is a gasket on there.The timing belt was cover in oil so I was thinking it was inside somewhere.

Hey Man,
About the oil leak from the front case area.....I just recently finished my first rebuild and had a huge leak from that area. There are multiple things that can leak and end up dripping from the bottom of the front case. I will list a few of the places that I know.
1)If you did a Balance shaft elimination kit, make sure you RTV'D the bolt that goes to where the balance shaft belt pulley went.(search I am sure you can find pics)
2)The 2 bolts that hold you Timing belt tensioner on go all the way through, so if they do not seal, they will leak. I ended up RTVing those 2 bolts also.
3)I ended up having ripped crankshaft seal on my brand new OEM seal. You can read about it here:

I just replaced that crankshaft seal and I am no longer leaking oil, hope this helps.

RyNo

+1. Also the block-off plate for the front cover can sometimes pop out and cause oil to leak. To prevent this it's a good idea to put a little JB Weld around the seal.
