Oil pressure drop when turning? (Reporting Back with Solution)

N/A dipstick, or late turbo dipstick?
N/A should be way shorter than the turbo one.
If you have the super long late turbo dipstick to spare, would you be willing to part with it? I broke the top off mine, and have a N/A dipstick in there to keep dirt from getting in for now.

To answer some questions. The dipstick has been in there the whole time i have had the car, but the engine was pulled and resealed/new bearings etc about 5k miles ago. I changed the oil inbetween there and put in the correct amount of oil. Im not worried about there being any damage to the engine.
Zero10 - How do I know which one it is? Its got a round loop on the top, and does not seem to fit quite right in my car. I could take a picture of it if that will help you. But yes, once I recieve my new (correct) dipstick ill part with this one.

OK, I hate to disappoint you – either the mechanic is way out to lunch or you still have a problem.
You are right about the dipstick – there are at least two different types of turbo dip sticks (different lengths) and the NA is a lot different.
But here is the catch – for the oil level to be low enough that you can see a drop in oil pressure while cornering on the street you would have three quarts or less in the pan. Did your mechanic really only pour three quarts in to the engine after the pan job???? If so there is a serious problem there. Everybody I know dumps in 5 quarts and then checks the level. If they poured in three and thought it was OK….well, you need a different shop.
If we figure that the guy doing the work was a little ham fisted then it is quite possible that the pickup was bent trying to force the pan back on. Either that or a crack has developed due to forcing the pick up with the pan.

I'll agree with Chris. 6 quarts or thereabouts is the number.
Observe the pickup through the oil drain hole; it sits at the very bottom of the pan - you would have to be really low on oil to starve the thing.

John - how could a the oil pump bolt not being torqued all the way create a problem just while turning or under accelleration? Thanks

I am going way out on a limb to guess that the shop also charged you for an oil level sender.
This is another thing that will break if you don't know what the hell you are doing around the oil pan.

Turbo dipsticks are flat and flexible, N/A dipsticks are round (the shaft itself) and inflexible.
There are 2 lengths of turbo dipsticks, I could measure mine and we can see if yours matches?....

Wow, that sounds some kind of dirty!

The car burns ALOT of oil. The car was fine for a while after they did the work. The work was done when the car had ~106k miles on it. I changed the oil at around 110k, with some top offs inbetween obviously. I also have topped the oil off after that quite a few times. My guess is the oil was just alot lower then I thought due to the dipstick/burning. It was not the fault of the mechanic putting to little oil in the car.

The shaft on my dipstick is indeed round and inflexible. It never fit quite right and I had always wondered why, now I know. Thanks!

If I put oil in a car, like Chris said ~5 quarts and then checked the level and it indicated way over the top line on the dipstick I'd at least consider that something was wrong.

The late turbo dipsticks are apparently round like the N/A ones, but much more flexible, and longer than the early turbo dipsticks.
Using an N/A dipstick will feel like you are going to gouge a hole through the side of the dipstick tube it is so inflexible, and it doesn't even reach the oil. You would be 5-6L over-ful using a N/A dipstick.
There are both round and flat turbo dipsticks, flat is the shorter one.
For the OP, where did you order the correct dipstick from and what was the price? Nobody seems to list them, and I need the same one you just bought.
For some reason a TSB regarding dipstick length and incorrect fill levels is coming to mind, but I can't find it anywhere.
