:confused:My daughters 1998 MK VIII has sprung an oil leak. Looks to be from the front engine seal/vibration dampener seal. Does anyone know if this seal is replaceable from the front, whereas I just have to remove the vibration dampener & replace the seal? OR, do I have to dis-assemble the entire front end of engine & remove the timing chain cover to replace the seal. Just trying to get an idea of the job ahead of me & how long I'll have the car down to repair. Any help will be appreciated. Thank you in advanced.

Pretty sure you don't have to remove the cover, to replace the front seal.
Remove crank bolt and washer
Remove the dampener
R&R the seal, re-install dampener(use RTV on the key/keyway)
Install new crank bolt(stock is TTY and one-use only)

Thank you! I wondered about the oil filter adapter, but wet oil around & below the vibration dampener & all over the passenger strut bushing (which was brand new 11 months ago) & K member. Everything is soooo packed in there, it is really hard to determine EXACTLY where the oil is coming from. It is definitely from the front of the engine though.

I'm going to go ahead & replace the oil filter adapter gasket while I'm down there. Anyone know the torque values to re-attach the oil filter adapter? Also, what is the gadget that looks like a little canister that is mounted REALLY close to the center of the vibration dampener? It has a black rubber hose (approx. 1" in diameter) attached to one end. Of course I have to move it out of the way to remove the vibration dampener, just wondering what the heck that thing is & what it does. Thanks again.

From the manual...

Tighten to 20 N-m (15 Lb-Ft) then tighten an additional 60 degrees

That would be the Secondary Air-Injection Diverter Valve. An emission control device used to direct air from the Secondary Air-Injection Pump to the exhaust manifolds.
