I have had oil seeping out of my car around the #1 cylinder since I can remember, never enough to worry but I figured with over 400k it has to leak oil from somewhere!

Anyway, I just noticed in the past 100 miles that I got some oil drops in my coolant. Needless to say the car hasn't moved since I noticed this. I am hoping that the #1 oil passage part of the HG has failed as several others on the board have shown their cars have. I do hope this is the case so I can merely clean surfaces and throw new gasket/bolts at the thing and be on my merry way

I was going to follow this http://www.mediafire.com/?sharekey=afb9bab7ca6154564012e8015643d9c8717206677e864e93

Now my question is I don't wanna replace the timing chain unless i absolutely have to so when it talks about knocking out these pins for the timing chain slider is that something I really have to do?

Also am I going to need any special tools?
I have a set of XZN 4mm-16mm

Do a search for my posts. Pretty much everything you would like to know about the job. On my engine it was #1 AND #5. I did mine at 240k - IMHO timing chain is a MUST at 400k - what are the chances that has already been done? You'll feel better for it either way. If I were doing it at 400k I would have the head rebuilt as well.

Whatever the case you are doing the right thing by parking now because you risk getting coolant in the bottom end (you knew that.)

good luck

Do not worry about your difficulties in Mathematics. I can assure you mine are still greater.

When you change the headgasket you have to take out two pins.
