Changing Timing Cover with Engine in Car
I did it in mine, piece o cake.
RTV in the corners where the pan meets the block, the short pieces I just cut to fit and used RTV on both sides as I didn't want to disturb the pan.
Make sure to lube the balance where it goes through the seal, just a light film of grease.
No leaks yet.
Oh, and if you get this big felt washer looking thingy, it goes inside the back side of the balancer, it keeps dirt out of the seal.
