AnswerCheck the crank pully bolt. If it has come loose you will have a leak.The crank pully bolt does not have anything to do with the crank shaft seal leak. Thebolt is independent of the seal. To replace seal remove crank shaft pully and you will have access to crank shaft seal, pull out & replace seal.
Remove serpentine belt. Remove damper pulley with puller. Remove oil seal.

Cost of a crank seal leak repair
Remove Aux belt Remove Timing Belt Remove the sump Remove Oil pump Remove piston big end caps Remove Crankcase and drop out crankshaft Slide off oil seal Reassemble in reverse order.
The easiest way to do it is remove the transmission and flywheel, Pry old seal out and off of the crank shaft. Then drive the new seal in, and put it all back together.
Remove the trasnsmission and you can then replace the seal.
Front main seal: Perform a timing belt change. After you get the old belt off, the front main seal is accessible. Pry it out and install a new one.Rear main seal: Remove the transmission, then the flywheel to gain access to the seal. Pry it out and install a new one.In either case, there is a tool called a Seal Installer. It screws into the crank and evenly presses the seal into the engine block. Auto parts store "loan a tool" programs will have these, and this is what you want to do because these things are expensive and do exactly one thing - install crankshaft seals. If you don't have one, you'll never get this freakin' seal in straight.
You must first remove the transmission and fly-wheel. Then you will see the 1 piece seal on the crank shaft. Pry it out, it will pop out. Then install new seal in it's place. A seal driver is the best tool to use. Be sure you clean the area good, and put some oil on the crankshaft before sliding the seal over the crank.
