Oil Leak- I'M SICK OF IT! Options

[Rymaster]

This car has been leaking oil for years now, about a quart of oil per oil change.

I'm sick of it! I've had it! I hate coming off of the freeway and people looking at me like my car is some kind of steam driven train from all the smoke blowing out from under the hood!
I for one am NOT a fan of the smell of burning oil!!! And I've smelt my last smelt of it!

So after completing my clutch job I'm all in the mood to fix this too.
I'm attaching some pictures if anyone is willing to possible suggest where they think the issue may be located.
I know from the pictures it looks like it could be the valve cover gasket, but I've already did this one and the one I replaced was actually perfectly fine!

I know the oil gaskets by the timing belt cover are popular but the very left side of my engine it rather clean next to the timing belt cover. It's in the back of my engine that smoke constantly blows up from (I drew an arrow in the one picture to show you). Most of the oil seems to be resting on the left side of the bottom of the air manifold. From there on down, things are really messy! But that's the highest point with signs of oil.

Any ideas???



where the smoke comes from







THE MESS!!!










back of air manifold is rather clean!

Clean next to timing belt cover

yeah the car is smoking from the engine when the oil hits the hot engine on the outside. I'm gonna do some cleaner when i have time and see if i notice the leak.

The cam seal was recently done with my timing belt too...

And the CIA is something i've just never really worried about, the cone goes all the way to the front left fender and i've temped the air before after a run and its plenty cold. I think it was routed that way just cause there is no room to fit it between the battery and motor mount

I had the same problem which is as the seals leak the air pushed the oil onto the driveshaft(I bet the boot is soaked) and as it spins it flings oil onto the intake manifold and it smokes as mine did really bad before I fixed her. By the way I notice your pcv valve is leaking as welll. Try a new rubber gasket for pcv but be careful if the old one is hard it may break and fall in. Get a new tube of some kind. I used a piece like that but it was shorter and it sat a little lower. Mabey it will work but the rubber is probably done. I probably should have went to toyo for that too.
Start at the top keeping in mind the oil will take about 3 months to burn away after all leaks are stopped.
Change valve cover gasket as it gets hard it will not prevent oil from leaking out. Since you have already you will need to snug it up a couple times or every oil change as it will loosen up. You cannot overtighten it all at once or you may ruin it.

Then if you notice the distributor o ring is bad behind the distributor the oil will find a direct line to meet all the other oil on the back of the engine so if you see the dribble there you have to change it.It cannot bre tightened.

then check power steering low pressure return line as mine was hardened and the toyota clamp was letting an iota of oil constantly dribbling to the place where the driveshaft likes to fling it. Use real clamps on it and if yours was as hard as a rock like mine was you will have to change it, just make sure you get actual power steering hose it was about 2 bucks a foot otherwise it will sweat oil. Now the fun part take off the timing cover and visually inspect what is probably the oil pump gasket leak(mine was disintigrated as I was putting in a quart a week). You will be able to see clearly the camshaft if it is leaking and if it is not(they looklike pretty sturdy seals) leave it for now. Now check fron seal at the very bottom and mine was still fine. Then I changed the oil seal and all of my leaks have now stopped and she is all dryed up. it is worth the 3 gaskets and clamps for the ps line to have a non leaking car. Some people say the oil pan can leak but a snug on pan bolts should solve that. Mine was fine. To do the procedures there are a few tutorials around this forum. I wrote one for the oil pump cover gasket somewhere. If you take off the timing cover carefully you may be able to reuse the rubber gasket type material.
Good Luck!
