Oil leaks - Help

[Dave W]

If this is your first major engine project take several pictures during disassembly. Mark both the cam belt at each pulley location and each pulley tooth. [for reassembly]
You need to lock the front damper pulley, to prevent turning, to be able to loosen the crank nut. I used a bar with a couple tabs that fit in the pulley to lock it down. Also an impact wrench would be very helpful.
The other area that is a PITA is the crank cam belt pulley. I was able to modified a on-head valve spring compressor [with small narrow thin fingers] that fit behind the pulley to be able to pull the lower cam belt pulley off.
Lube both the OD and ID of the seal before installing the new seal.
The seal MUST be straight when installed.
On assembly, lube the crank shaft to prevent the cam pulley from rusting on the shaft.
Depending on engine service, you may want to look at replacing the cam belt, idler pulley, and may be the water pump while the front of the engine is disassembled? Inspect the other seals and gaskets in the general area.
Getting to the seal is the hard part, removing all the stuff for access. It will probably take 4 or 5 hour to complete if doing it the first time. With help you should be able to reduce the time by a couple hours.
Last I would get a service manual if you do not ready have one. To make sure you get the cam timing set correctly.
Just do not rush the project and keep every thing organized.
