Wow...I got so dizzy looking at your video. I stopped after the second one. You need to do this during the day or with better lighting so we can see and better able to help you.

There is a LOT of expertise here that can help you, but you need to give us better info. Good attempt at the videos, but they are very dark and move around a lot, so its very hard to tell what issues you have.

The first steps should be to cleanup the mess and then you can chase down the leaks. Clean off all the gunk/old oil/dirt off the engine top and bottom (using a good degreaser) and then run the car for a while, it should be much more obvious where the oil is coming from. you also should do that before you remove any valve covers, since you risk having debris falling into the engine, which you want to really really avoid.

So, first clean, then get some lighting going, and then just post a few shots (or videos). BTW, moving around the camera on fast pans and unsteady hands is a no-no, it will just make the views sick -> hold the camera still on some spots and then slowly pan to the next shots.

Best of luck!

cheers,

Mike

I give you an A for effort.

Do exactly as Mike says. Clean. Clean. Clean. Then drive it and take some pictures with a flash (or video with better lighting).

Two spots that leak a lot on these cars are the lower valve covers and the timing chain housing. Get cleaning.

Default leak 993

i was tighten the bolts of the low valve cover, and after of that i put a big papper under the engine and after i turned on the engine for a 6 or 7 minutes and after of that appears a spot on the half between the 2 wheels.
do you thing it is very probably that the leak is on the timing chain housing?
because if you have seen the images it seams that the bolts of the timing chain housing are stained, do you thing the same?

but suppose that the leak is on the timing chain housing, it's possible to replace the gaskets without remove the engine?
i will clean it but i think if the leak is on the lower valve covers i can fix it without remove the engine, otherwise i think i will have to remove the engine, do you thing the same
thank you very much all of you

You can do both valve cover gaskets (top and bottom) and chain cover gaskets without dropping the engine.

The chain cover gaskets are more involved, since you need to pull most of the exhaust system, A/C mounts, crank pulley, engine support, etc.

Cheers,

Mike

Done that a few times - again its not that hard, but you will need to support the engine - but it can be done without dropping the engine....
