Darth is ready to be completely reassembled tomorrow afternoon (ok today, I gotta start getting to bed earlier!) Question...do I just jump right in and fire it up or should I leave the DIS unplugged and crank the car a bit? I didn't use assembly **** on the new bearings but they were coated liberally with oil prior to assembly. A co-worker suggested I crank the car for a little bit before starting, to build up a little bit of oil pressure. Suggestions?

What you want to do is crank the car untill the red oil pressure light in the cluster turns off. It will turn off when sufficient oil pressure has been built up in the system. In my SHO when I did this it took 2-3 cranks of 10 seconds to build it up. But, once that red oil light extinquishes then you are good to go, but do not attempt to start the car untill that light is out. You will want to crank the car of course with the DIS unplugged.

I would pull all 6 spark plugs and turn it over until the red oil pressure light goes out. I would have used assembly **** as well, but since you did not, all the more reason to pull the plugs and keep a load off the bearings prior to having oil pressure.

I would think that would be overkill, but if you have the time go for it!

Can I do this with the cam covers off, or am I going to spew oil everywhere? I wouldn't mind rechecking the tension on the cam chain tensioners...right now there's no tension in them at all but I was told that the oil runs out of them over time, and this car has been sitting for about a month now.

Went ahead and pulled the plugs since the top end was all apart anyway. Cranked it over a few times and the pressure came right up :thumb: Thanks for the advice all!

The cam chain tensioners are not powered by the engine oil supply. They are spring loaded, free-standing units.

They do, however, rely on oil acting as a damper to hold them up once the motor is running to hold constant tension on the chain during varying loads.

how is that if they are free standing, self contained units? Obviously the oil does lubricate the various contact points, but beyond that I dont know of any other role for the oil.

There's a small hole drilled in the side of the tensioners where oil finds its way in. If you pull a motor apart, you'll notice on a good tensioner that when you compress it, it takes a bit of force to start it moving, and once you do, it will squirt oil back out that hole.
