LS7 oiling questions
I bought an 08 Z06 and am rebuilding the motor and prepping it to do track time. I plan to make it a stock rebuild with reliability mods.
I have some oiling questions.
Does anyone have an oiling diagram?
Where is the oil cooler in the oil circuit? Between the scavenge pump and the oil tank? Or between the high pressure pump and the oil filter?
Are the oil lines going to the radiator for the engine oil or transmission oil?
Has anyone retrofitted the ZR1 oil-to-water cooler to the Z06?
I found this diagram of the LS9 / 09+ LS7 increased-capacity oil tank below.
Is there a way to purchase item 'B' and add it? Or am I stuck with buying a Lingenfelter modified oil tank?
Thanks all.

I don't think you can buy the pony tank for the oil tank. There are more differences, the top on the later tank is plastic for instance. And you'll need to vent it too. Very often people are selling tanks in the for sale area. In fact I think there is one posted there about 4 pages back as of now.
There is a transmission cooler in the radiator, there are two lines for that. The oil cooler is in front of the radiator, not in it.
I don't have a routing diagram to post.
You can only buy the complete tank assembly, so the modified Lingenfelter tank is probably the best option.
Our oil pan baffle for the LS7 pan also helps reduce oil starvation: http://www.improvedracing.com/oil-pa...fle-p-675.html
If the factory oil cooler setup isn't sufficient, we also make an upgraded oil cooler kit: http://www.improvedracing.com/oil-co...600-p-768.html
For extra precaution, I would update the scavenge pump while breaking everything apart as well.
