1991 C4: 3.6 out for headstuds and more

Hello all

This is Rus from CT. I used to own a Carrera, whose top end I did with a massive amount of help from this forum. I sold that car to a great guy I met on Pelican and have driven an E30 since. I just sold the beemer as I got a deal I couldn't refuse on a 964. I found a broken headstud (#1, top) and so pulled the motor.

The plan is to replace all of them with Supertec units, which I have in hand from our host. I have budgeted to have the heads looked at at at minimum clean/surface, but obviously address anything else that's needed. I'm sure they'll end up with new guides but will rely on my machine shop who does many heads per week for guidance.

I'm not necessarily looking for performance or big upgrades just to get the car back on the road, the right way.

I'm posting a thread now as I get to the "real" part of the project. I am shopping for the all important gaskets and chemicals and came here to get the latest and greatest recommendations.

When I did the 3.2 there was an all inclusive gasket set from Wrightwood which 'curated' the best of each selection. At least that was my memory - I'm sure I shopped around for other parts.

For the 964, Wrightwood makes a chain housing kit that I was planning on using. I would love to hear recommendations from others who have done this work on all the sealants, gaskets etc they used. My base presumption is to use what worked on the 3.2, when applicable.

The motor is up on a stand and I'd hoped to have the heads off this weekend but can't get to the last three heat x hex nuts and have some offset wrenches and swivels on their way to me next week.

One observation I have to share - since I was waiting for a loaner P201 tool (thanks John J!) I decided to strip the motor before dropping it. I was very happy with this approach as it gives much greater visibility to whats going on during the drop and greatly lowers the total height the car needs to be in the air.
