928 cam housing R&R procedure?
Hi all,
I have an '82 928 (I believe it is 16 valve), I thought I was removing just the valve cover, (to repair an oil leak), but when I got all the fasteners removed, I realized that it is a "Cam Housing", now it is just held on by the timing belt/cam gear! (See attached photos). Anyone know what I should do next? I am concerned about interrupting the cam timing, etc.. Any knowledge you may be able to share would be greatly appreciated, I cannot find the camshaft removal and replacement procedure even in the factory shop manual or anywhere online so far... Thanks from Tom!

At this point, you probably need to remove the front of the engine to remove the timing belt et.al. since there would be absolutely no way (Murphy's Law) that the cam tower gasket would ever reseal. Once you remove the timing belt, you could remove the cam tower, remove the old gasket, fit a new gasket, and replace the cam tower, and retorque the bolts.

Put the motor at TDC first. The belt to cam positions is not relevant as you have marked with a sharpie. Find tdc on the harmonic balance and notches on the cam gears and line them up to the correct marks. Then you can precede to remove the cam tower. Where some noob sealed the front of you housing with RTV is wrong too. There's a few O-rings and front camshaft seal to button up the front.

I just did this repair on my car a couple weeks ago. See my thread here:
Time for a minor (or major?) rebuild (LONG) Some photos of mine going back together: 9TWO8Guy's Library | Photobucket Since you will be removing the timing belt during your cam housing R&R, it's a good idea to replace the belt, water pump and belt tensioner if they haven't been done already. Also, it looks like your fuel lines and PS high pressure hose are original. I would highly recommend replacing all the rubber fuel lines in the engine bay as well as the high-pressure hose as they are potential fire hazards on a 30+ year old vehicle. Most everyone here will tell you the same
