It is an interesting concept, but just that. Just because you're not seeing tons of oil there doesn't mean it isn't being pressurized throughout the block.

We are going to do the cover and the block. My car wont run for a couple months but i will report back when it does.

that valve cover hasn't been off in over 10 years. i am not removing it at this point haha. i refuse to believe that any part of the engine lacking oil will last very long at all.

Yah, well I still believe in Santa Clause. That doesn't mean that my reality matches the reality of others whom now where big boy pants.

This was a good/informative thread that is turning to **** by recent statements being made by people who are either uninformed or have not read all of the posts in the thread. In either case, this thread should be locked & made into a sticky.

Yep I understand the concern for people that do not know as much about the LSx oiling system and if done correctly it probably isn't bad but the oil passage down the other side is huge already so the only thing limiting the oil at all over there on the passenger side bank is the front cross over but like we have all seen there does not appear to be any issues anyway from what I have seen. With much larger lifter clearances this mod will help a lil for sure but also take some oil away from the crank as opposed to making it go through the other side first.

Maybe since the opposing side has no main oiling drilled to it though it will also flow the other way around there and help oil the front mains a little better? You'd have to log oil pressure in a running engine at the front and the back with and without this mod and see what you get. Then you'd really learn something. From what I have seen so far still though it does not seem to be a big deal though.

Very good topic here....

I have a la motor I am getting ready to go through and was wondering how all this nodding to the oil system has worked out. Is their any issues out their now that you have run the engine for some time now.

I still don't get it, is this a problem associated with only 97-98 LS1 blocks or is it all LS1 and LS6 blocks?

Only the early LS1 blocks lack the channel as well as all of the iron truck blocks. The LS6 and later LS1 blocks, most '99 and newer, have the cross channel in the back.

I would of just used a old gasket to begin with, it would take the abuse of the slips, show you the correct areas to grind all at the same time.

Sorry to bring this one back from the dead, but....
I have both an early LS1(97' C5) and an 04' 5.3L out of a Yukon.
What ever happened to this? I found this article that points out to not use the early LS1 engines for high performance apps, is this the same thing this photo shows?

And if this was really an issue, seems the aftermarket would have just came out with a better rear cover with the channel built into it.

That rear channel is not a problem, the early blocks had other things that make them less desirable.
