[FC] Couple of questions

[Ken Hand]

 ??? As has been said the top engine baffle plate can only be installed one way. If you want to do it right the first time look at the way the engine rotates, the flat side goes down and the openings go away from the direction of rotation. Think of it as the crank trying to throw oil into the top baffle, that is NOT what you want, you want to keep oil out The gaskets are also asymmetrical but they will go on in two directions only.

??? I would do the compression test before you put things together, If you are getting lots of oil out the breather tube there might be other things wrong also.

??? If you decide to put things together, a thin film of RTV, silicone, does wonders. Also get the split lock washers for under the heads of the bolts then the flat washer. Snug things down to where the lock washer is just compressed and leave it set over night then finish tightening the bolts the next morning. That should get you a leak free gaskets for a long time.

??? As far as u-joints, there are u-joints and then there is "Brute Force". All the other greaseable ones I have either broken or worn out. I have yet to wear out or break a "Brute Force" u-joint, even on my race car They are a bit more expensive but well worth the money The u-joints are the older standard chevy size and can be gotten at your local NAPA, Autozone, Advance Auto, etc. Not sure about the Brute Force at NAPA though.

If you really need to use the greaseable ones then make sure that you put the grease fitting so when the differential is driving the yoke you are compressing the grease fitting, not trying to open it up. It takes a little thinking but you won't break a u-joint that way.

Could someone tell me the correct direction for the steel vent plate 
that is under the fan cover?  I was getting a large amount of oil out 
the the top cover and the pcv pipes and took it apart today to take a 
look at the gasket.  The gasket was leaking so thats an easy fix but the 
there was a tremendous amount of oil between the vent plate and the top 
cover.  It was installed with the opening in the slots facing the 
passenger side of the engine.  I have looked in the tech guide and the 
service manuals but cant find a picture or description that clearly 
shows the proper direction.  I will be fitting the vent plate inside the 
top cover as detailed in the tech guide but want to get the direction 
correct to avoid the oil in the top cover as detailed in the guide.

The other question concerns the rear U-Joints on an FC.  Are they a 
standard GM part?  One of mine is starting to make noises and would like 
to change it before it grinds itself to death.
