Timing chain leak on my 94 Dakota. 3.9 V6 Local shop wanted $712 + tax and shop supplys if I supplied all of the parts. I decided to do it myself. Timing chain had about 1 1/4 " of play so a new one was called for. Front main seal which attaches to the timing cover is shot and it is part of the oil pan gasket so now the pan has to be dropped. I have a lift but no way to get it on because the engine is now apart so I'll have to work on my back. Happy days.
