The tall cylinder mounted to the dry sump tank is the transmission expansion tank. I run the vent line off the trans to the bottom of that tank. During open track days I have seen the transmission push out fluid when it is hot. Makes a mess. So now we add an expansion tank. Fluid get hot gets pushed into tank then drains back into trans when it cools.

I have to admit I've been lurking about looking to replicate this oiling/venting system. I think Donny was questioning this before, maybe on a different build, but I'm wondering how to route the oil return from the air/oil separator. Above or below the oil level? check valve? No check valve? Vent it to atmosphere?

Malitude was even further out of your comfort zone I'd say and that was a grand slam of a car in my opinion.

As much as I'd love to see your idea of a 2nd gen, I'm still amazed and appreciative of how open you are with all of your builds. Thank you, Mark.

Ok, another question for you Mark!

With the DSE subframe, what transmission cross member are you using?

I know the DSE engine mounts move the engine back 1.5 inches, and they say to use a stock style cross member. What are you using in this build, and what have you used in past builds? The closest pic I could see was on post #61, but it's far in the background and I can't really make it out.

Thanks again for your time and expertise!

I’ll let him verify but looks like (holley) hooker blackheart one to me.

The LT motor mounts and trans cross member are both hooker blackheart. We built the first set off gunner and got all of the angles set and holley is now producing them. They fit great and everything bolts in as it should. You do have to raise the tunnel to get correct driveline angle

Ahhhhhh, that's right, I forgot this was an LT series engine!

What have you guys done for LS engines in the past using the DSE subframe? I know DSE has their own engine mounts for the LS engine for their subframe, but kind of leave you hanging on the trans cross member.

And would you happen to have any pics of the interior trans tunnel mods you've performed?

Thanks!

If you go back to the build of Jackass 2.0, you will find the pictures there on the cross member Mark has built on Hellfire and JA for the LS9. It is on page 68. If you look at some of the DSE builds you will also find they have built a similar setup

The nipple off of the bottom of the air oil separator is mounted higher than the oil level and the line off of it returns low in the tank below oil level and does have a check valve coming right off of the separator
