Can anyone help with a ls1 swap??

Next decision... keep the 5.3 for a project motor or sell it and use the money on mods??

And now the fun starts. The synthetic oil found a crack to leak out of.
Oil seems to be coming from the right side of the engine up high. It only seems to leak oil when the motor is running, so i am assuming a valve cover gasket...i hope.

I popped the metal cover piece off of the trans to see if it was coming from the main seal, and there was no oil in the bell housing; so i think i am safe on that...

i havent really gotten to look things over really well yet because it is hot, but what would ya'll guys say? Maybe it one of the sensors on the back???
