Hi, thanks for the replies. I am sure the valve cover gasket is not leaking. When I installed it, I did follow the manual and put the sensor safe gasket sealant in all the 8 places (4 on each side) (and cleaned with alcohol the contact area)
I am sure that the gasket is not leaking, because as I mentioned before, I cleaned up the engine and now I can see that there is no leak from the gasket.
The leak is somewhere close to where intake manifold is connecting to the block (on the passenger side). There is one insulated-looking wire (about 1/2 in diameter) and other things, that I cannot discern, all covered with grease (and that grease is for sure oil, as I stuck my fingers in there and it was the dark reddish color)
May be there are more than one leak, because the drops on the driveway are very light color. And to me it does not make sense, because oil should be dark reddish as around intake manifold gasket)(it is not synthetic). I checked power steering fluid and the hose that goes out of the fluid reservoir and it seems to be OK (I actually had wheels turned a couple of times while the car was running to observe is something leaking under pressure).
By the way, thanks for pointing out the torque specs on the spark plug cyl bolts. I did have them too tight (my torque wrench is 3/8 drive, but the 30 mm socket for those bolts is 1/2 -- so my torque wrench cannot be used (I just ordered a 1/2 drive inexpensive torque wrench ) -- but for now I just 'guesstimated' the torque).
I am thinking that will not be avoid to take everything out up to the cylinder heads... and may be then I will find one leak, and then the hunt for the second one will begin... :-(
I only can work on my mom's car on Sat and Sunday, so I wanted to ask if anyone has experience how long would it take for a newbie to do get to the cyl head gasket (the Haynes manual, I use, basically tells me that I have to flush out radiator fluids and take bunch of stuff out) .. I am afraid I will not have enough time (but if get there, I will replace bunch of gaskets and the timing belt, and whatever else I can find easy to replace)
Any other ideas/tips are greatly appreciated.
