need help identifying oil leaks w/ lots of pics

Hello, I am trying to get my lude in tip top shape and looking for old seals and gaskets that need to be replaced. I am using this guide as a reference which helps out tremendously. I still need verification from more experienced members before I go out and buy the parts to replace.

OFFICIAL OIL LEAK GUIDE:
The Official Oil Leak Guide - Honda Prelude Forum : Honda Prelude Forums


Now, on to the pictures of where the oil is located in the bay:

1)
Just underneath the distributor seems like there is some fresh oil here. I can't tell if it's coming from the valve cover, and the gasket is leaking or if it's the distributor O-ring. I recently changed my valve cover gasket and put RTV blue on all the angled edges of the gasket, so I don't think it is the valve cover. I am not going to rule out that it is the valve cover though.



Here is another shot, this is closer to the valve cover just underneath the spark plug wires:




2)
This oil is located above the ports on the IM. Have no clue where it's coming from. In the picture, the oil is on top of the port beside the fuel rail and also between the port and EGR.




3)
This leak is in the crevice between the valve cover and EGR. I'd say below the fuel rail on the same surface as the bolts that hold the EGR in place.




4)
This leak is located on the drivers side of the block just underneath the bar code as you can see. I have no idea what is causing this leak either.

Re: need help identifying oil leaks w/ lots of pics

1 - Could be Valve cover gasket like you said, distributor o ring, vtec solenoid gasket, or the cam cover thing there... May as well replace them all they really aren't that expensive.

2 - Are you sure this isn't oil from the first leak also? I cannot really think of anything that would leak directly there, but it is probably just oil from your first leak.

3 - I would say the same thing as two really... Did you tighten down your valve cover properly with the right torque specs and everything?

4 - I would need a picture from further out also.

Re: need help identifying oil leaks w/ lots of pics

^ill get you that picture from #4 as soon as I can. what are the correct torque specs for the valve cover? i made sure i tightened them in the criss-cross pattern and really tight, but not overtight.

im going to clean the areas where the leaks are occuring, first start by changing the distributor o-ring.

Re: need help identifying oil leaks w/ lots of pics

the valve cover doesn't need to be really tight. its only 7 or 9 lbs of torque in the honda manual. Also, I have a similar leak under my dizzy, and turns out also, an internal dizzy leak. So, how does the insides of your cap look?

Re: need help identifying oil leaks w/ lots of pics

^hey thanks for the torque specs, i knew it was somewhere between 8-15 lbs. sorry for the noob question and lack of technical terminology, but what "cap" are you talking about? the distributor cap? if so, i have yet to check out the inside of it and willl change the o-ring when i get the chance.

Re: need help identifying oil leaks w/ lots of pics

In pic #1 I can't help but notice what looks like a breather tube with oil residue on the end. What is that fed from?

yes, If your distributor cap has oil in it, replacing it might be a good idea. I made a build thread today and at the bottom is a pic of my cap with an oil leak. A brand new replacement on ebay is under $100 for mine, not sure about yours. Honda majestic is a good place to find part numbers, but the prices are pretty steep, so I usually hit up the local wrecker for parts that will work.

Official H22 Oil Leak Guide

Look through this. I'd say 1, 2 & 3 look like your valve cover gasket and cam plug.

4 will also need a pic from further out. If that's the timing belt cover, it could also be from just your valve cover gasket.
