The power lost to the EGR will not be made up by advancing the timing.
Max power is made w/ max charge density. EGR serves to reduce the charge density, lowering the speed, temp & pressure of combustion.
Arron, you need to worry about that water pump
Wouldn't it be likely that a properly functioning EGR system wouldn't negatively affect power though? My thinking is that if the system is working the way it should and not hurting power, it'll allow you to advance your timing to the optimal setting without causing the engine to ping, which in turn would help with power.
The downside I see to having the EGR though, is the source of carbon buildup, and it took me a long time to get rid of as much carbon as I could after desmogging.

You might try adding a catch can in the PCV line to separate some of the oil out of the intake manifold. Check out the thread in the 80 section that discusses catch cans. I added one a couple of weeks ago before a 1,000 mile trip and the gunk it collected was nasty and plentiful and would have gone into the intake manifold otherwise.
Engine Oil Vapor Separator Catch Can at HMS is the one I put on the 80 and haven't checked the innards of yet. It made the same trip to Moab as the 62 with Craftsman air compressor filter/separator that I checked this morning and cleaned several ounces of slime out of. The one from the link is expensive but purpose built and probably more effective but the Craftsman thing worked too for a lot less money. I went with the expensive one on the 80 as the truck is supercharged and requires a little more sophisticated separator to work well. I'll report on what I find in it.
Checked the container of the 80's HMS separator and found about an ounce or less of what pretty much looked like engine oil. It was much less like sludge than what came out of the 62's can. Couldn't just turn the can upside down and let the oil drain out as the interior sides catch a little bit as they are designed to do. Could have used the drain in the bottom of the can but wanted to measure what was in there for a first time baseline. After 1000 miles, both the Craftsman and the HMS appear to do what is desired of them and the air going into the cylinders is cleaner than it was before the separators were installed. If nothing else, less gunk buildup in the intake manifolds and backs of the intake valves, but if the propaganda I've read is even partially true, then other benefits will make themselves evident.
Steve,
Throw up a pic of the setup on Bart! With my intake now nicely cleaned I want to install one tomorrow!

Dan,
Yes I pulled it to install rebuilt injectors to cure a clogged injector problem.
If you have the time I would go ahead and pull the intake and install rebuilt injectors at the same time. If you are in a hurry I think you could to a pretty good job by just pulling the throttle body and using a full can of B&G intake cleaner. Actually you would need to pull the EGR and the cold start injector to get more angles of attach with the spray.
B&G is amazing stuff and will really rip away the accumulate gunk just with the spray pressure.
Probably a good idea to change the oil after dumping a whole can into the crank case via the intake though.
Since you have an extra intake sent it to Randy for this treatment.
No thats not mine. It is on Mark Mellon Werch's 3FEJ40. I just cleaned mine up.
