I've been trying to locate an oil leak on my 92 turbo talon, I have some possible spots like the crank case gasket, exhaust manifold gasket and the head gasket but not sure if I'm right so i want your opinon on this, the reason why i want to find the leak is because I got oil on my new alternator and its not coming from the power steering pump its anothe surce,I got some pic here, thanks in advance

from what i can see in the pics, i would say the oil around manifold could be from the crankcase cover; mine looked the same way, i put on a new gasket, and it stopped leaking. as for the oil on the lower engine area it looks like it could be the headgasket; you also might consider the front cover gasket, those seem to be prone to leak a lot.

what exactly are you talking about? thanks again

where the oil pump assembly is located. i've had to change mine a few times and even with RTV it would still leak.

i was also thinking, you could clean off the engine as best you can and let it sit and run a few mins and see if you can spot where some of the oil might be coming from.

Pretty sure he's talking about his one. #38 in the pictures.

The (one thats quadrilateraled) front cover is the assembly that houses the oil pump gears.

Those pictures show alot of places prone seals leaking oil. In the first 2, it could be the valve cover gasket. The 3rd one shows the stock oil feed line. It could be that the banjo bolt and crush washers leaking. It could be leaking down to the oil return line to the oil pan. Those stock lines can sometimes crack in the flex section aswell.
The 4th one shows the half moon plug. If you replace the valve cover gasket, I'd recommend getting this plug aswell. Along with a dab of silicon sealer. Also the CAS has an o-ring on it aswell. They usually get hard and do not seal correctly, which can cause it to leak down to the tranny(like in pic 7).
In pic 6 there are camshaft seals behind those sprockets. They can also leak down to the oil filter housing.

yep. that's the one.

From where do you think the oil is leaking from on the alternator? ps pump contections arent leaking could it be comeing from the exhaust manifold?

 

[Boostjunki84]

can't be sure from the pics; best to clean off the area and see if you can spot where the oil is coming from.

Ok so far I found that the exhaust manifold gasket is leaking (its visible) and the valve cover gasket will need a replacement as well at the stock turbo oil feed/return lines. I'll replace these parts and see if its still leaking. Also how dificult is it to remove the lover timing cover? do i have to remove any pulleys?

its not difficult if you have asain hands like me but yes the main drive pulley has to be removed and the accessory belts taken off of course and then theres like 8 or 9 bolts i think? holding the lower case on. be careful and patient taking it off though so you dont break it it has to come up and out just right oh also the side motor mount has to come out

In the pic of the exhaust manifold with the dipstick in the foreground it looks like the oil is coming DOWN onto it. That would be a valve cover gasket leak.

had to remove mine when i was doing a timingbelt in the driveway with just some basic handtools one afternoon, it's not too bad. just take your time.
