C6 zo6 cam install/front cradle issue

C6 zo6 cam install/front cradle issue
Hopefully someone can help me out with this issue.....I recently performed my own cam swap on my 09' C6Z, like many others I had to lower the oil pan slightly to make room when I removed the oil pump. To lower the oil pan most of the write up's mention lowering the engine cradle to accomplish lowering the oil pan. I lowered the engine cradle about 1/2 inch, did the cam swap and bolted everything back up. Once I got the car off the jackstands I placed the car on the ground in my garage and noticed there is a larger gap between the tire and fender. I'm thinking I didn't torque the front cradle to spec causing a separation between the chassis and body of the car, can anyone point me in the right direction? Thank you!

I'm fixinta do a cam in my 05 ls2 and am told I should do the oil pump while I'm in there so I'm interested. Is there a trick to getting it out without dropping the pan/cradle? I've never done it so appreciate any advice

As you can see in my thread opinions vary, mine is a 09' ZO6 and the pump would NOT come off of the crank snout. I can say from experience not every car is the same so if there was a trick/method other than just pulling it off with your hands I would be open to seeing how it's accomplished. Some say you have to use a puller to do so but have to do so carefully because of the oil pump seal others say they come right off. It took maybe 30 min total to lower everything, once that was complete it came right off, good luck with your project!

I would love to have had you there to show us the way. There were 3 experienced mechanics there and the pump was slightly moving but would not come forward, I can definitely see how lowering the oil pan is the safer method since it separates the oil pump seal decreasing the possibility of tearing the seal. Once we lowered the oil pan about 1/2 inch the oil pump came right off.

Installed a cam and heads on my '06 LS2 about 5 years ago, didn't drop the cradle, just loosened the pan bolts(about 4 back on each side) and removed front cover. It's difficult to get to the bolt for the oil pump pick up, but not impossible. I'm currently getting ready to do an install on an LS7 and this should be even easier, no pick up to be concerned about, all oil pump connections are "O" rings in pan gasket, lower pan slightly, remove front cover, do your cam install, pit a little RTV at corners of pan, cover, block and button it up. Doing an LS2 or LS3, you might want to carefully put a rag under pump/pick-up connection when removing/installing bolt, don't want it to drop in the oil pan.

I can tell you from experience, the car will sit higher immediately after dropping back down, and will actually take quite a few miles of driving to reach "settled height". I've played with my front height adjustment bolts enough to know this. I cannot explain why - but it takes quite a few miles.
Can't help w/ the cradle though...

Maybe CMy6 can provide some detail. He seems to know most things but provides little detail. Ps if you are going to tell someone how Not to do it, then you should provide the information. Otherwise your comments are useless and not helpful to the forum.

the information your inquiring about is posted in this thread.no trick to removing oil pump in wet sump LS2 or LS3 C6 cars.remove oil pump bolts and your pump comes right out once the front cover has been removd.no need to lower front cradle or oil pan

The point of this thread was not how to teach anyone anything, there's plenty of DIY on how to do these projects so no use beating a dead horse. If you read the thread you'd know that I actually did but ok.

The wet sump cars do not require the oil pan to be lowered. All that is needed is to carefully remove the oil pump pickup tube from the pump (picture below), in order to remove the oil pump.
Although I’ve never done one myself, the dry sump cars (like the OPs car) are a completely different deal, which DO require the oil pan to be lowered, because the entire oil pump system is a different configuration altogether.
Not that this was the topic that the OP wanted to discuss, but since the resident CF forum a$$howl clearly couldn’t resist the opportunity to visit upon us, yet again, his gratuitous ignorance, I thought someone should point that out.
Now, the the point of the OPs actual question/issue, as mentioned already, it is normal for your car to sit a little higher for many hours after having the suspension unloaded for a while. It will settle back down to normal ride height after you do a few launches with that new cam.
