LS3 oiling question.

[Terry Oxandale]

Well, I took out that plug. I just don't think there is any way to get a fitting into that hole. I think it is a 16mm thread but I don't see how to get a 90 on to what ever you might screw in there. It would be the a great place but I don't see how to make it happen. :thumbsdown:

Dean,

I purchased a special adapter from Dailey Engineering for this port for my dry sump. It is steel because of the thin wall required to make the adapter work and supply sufficient flow. Then any A/N fitting can be used with this adapter (-12 I believe, but can't remember for sure).

I think it's only a -10 now that I look at it.

I talked to those guys yesterday. It was a $69 fitting! I decided to go with the lingenfelter adapter instead. That way I can add a cooler, a temp sender and a pressure sender. I think it is worth the extra $30 for the other features. I already have lines and fittings for a -10 setup anyway. I think I might even have a cooler still in a box somewhere in the garage too!

I personally feel that while an Accusump is a good workaround safe guard, a dry sump system is worth the money for peace of mind and real on track reliability.

I know its not as affordable but its a lot cheaper than an engine rebuild in the long run....

Just be sure to add good inline oil filters too, Oberg/plate style ones are handy to keep a close eye on engine wear.

There are many true bolt on systems for LS engines...

I agree Fran, I think I'm heading in that direction.

I've bitten the bullet and gone full dry sump. A lot of work, including a lot of custom fabrication. I wish I made the decision sooner... well I did, but I was stuck on keeping my AC and the options at the time which allowed this didn't offer the oiling performance I wanted. The options that offered the performance I wanted didn't allow me to keep AC. So I designed my own setup.

The great thing about the SLC is that it offers a lot of options with engine bay setup and plumbing. I don't think I've seen any SLC dry sump setup the same, and mine is different than the ones I've seen on this site too.

I have a brand new 2 quart Accusump setup, electric valve, I won't be using if anyone is interested.

So Fran- are you feeling different about the LS3 Accusump vs the LS7 dry sump or an adapted LS3 dry sump? Time is ticking- I/you/we/someone has to decide. Do I need it?????

LS3
Street....stock wet sump LS3
Street/ occasional Trackday ....stock wet sump...additional oil
Track car only....wet sump with accusump or race dry sump
We have more than one guy running LS376 on track regularly with nothing more than additional oil ...not even an accusump.
LS7
Street...no change
Track..... larger volume dry sump tank than stock (Peterson 3 gallon)

An LS376 with 480hp and a true race dry sump system will still cost $5k less than a stock LS7 with the stock GM dry sump which is not as capable as a race dry sump system.

Its all about how much time you will really spend on track at max attack and what you want to budget for your engine package.
