Getting back into repairs and mods to my DD "black and green" Civic. I will be posting more in this thread in the coming days/weeks.

First, repairs before mods. I am still chasing down the various multiple sources of the persistent slow oil leak that helped derail my full belly pan project. I work slowly because I am inexperienced and cannot take the car off the road often or for long.

Here is my crank pully seal replacement, a job like most that I had never done before or seen done before. Here are a couple good techniques for installing the replacement easily and with acceptable precision.

Tips:

First I took pictures of how the OEM seal was sitting. The seal should be flush with the oil pump housing.

Then I began replacement.

A paint can opener works excellently to pop the seal out without the risk of nicking the crank shaft or the seal housing:

To install the new seal I used the large deep socket to start the seal evenly. It fit over the end of the crank shaft perfectly. Light tapping with the rubber mallet got the seal mostly into place. Then I used the socket extender to fine tune the seal's placement by tapping around the outer circumference until the extender tapped the metal of the oil pump housing:

A feeler gauge was a great tool for checking that I had the seal in flush with the oil pump housing. Perfect.

Final view.

The core tasks above are quite easy. But getting to the seal is a little bit of a PITA because you have to remove the timing belt. So I was extra cautious with the install because I did not want to have to go in again.

But, the oil leak is still with me, because the cam shaft seal is also leaking. I suspected that when I was working on the crank seal. But I decided to wait and let running the car confirm it for me. The cam shaft replacement is another new process for me. So I was cautious and conservative. I still have the leak, though it is slower than it was. I'll get after the cam seal sometime, but not this summer. I have other mods/repairs I will post about as time allows in the coming days.
