Default How much do you lose ET wise?

From a 3200 stall to a 3600 stall?

Looking at a vig 3200 because of my rear main seal

And was wondering will it hurt my ET's that much? and heard the Vig's stall higher then advertised so it would be more like a 3400. What you guys think??

You haven't even figured out where your oil leak is coming from yet, and you're already talking about putting in a stall.

Figure out where the leak is coming first. Oil pressure sensor, intake manifold, oil dipstick or RMS.

And don't be so quick to judge a car with a 3600 since you have NO experience driving one. A good 3600 will drive similarly to stock. I ran a Midwest 3600 for 7 years, both when it was my DD and when it wasn't.

ET gains can't really be quantified on paper. The gain (or loss) between the two stalls rely on far more than just their advertised stall speed.

Well going out right now to further look into it but the way its flung up on the transmission and the under carriage of the car at first thought I think RMS and the intake usually leak from the back?

Intake manifold leak is FAR more common than the RMS. Not saying the RMS is not possible, but if your IMG has never been replaced/repaired, that's the more likely culprit.

alright I'll go out and take a look can I just run my hand behind the intake manifold and find this or how can I distinguish because it seems like it's going to be the back on the intake

If it's an oily grime on the block it's most likely your IMG. Try cleaning it/wiping it down with cleaner to get it as clean as possible, then run the car for another day or so to see what happens.

If you're still not certain, you can pick up a dye kit from the parts store to help source the leak.

Went out there and everything under the car is a total mess with oil. and this had to be recent because just hung my exhaust back up 2 weeks ago and wasn't a mess

That and looks like there might also be a leak on the timing cover.

I can't win with this thing

With the gaskets I'm seeing they only seem to go around the heads.

Take it thats why they tend to leak in the back?

The theoretical (and accepted reason) for the intake manifold leak is due to the high heat of the EGR tube breaking down and weakening the gasket seal back there. Whether or not that's the case, no one has yet to prove or disprove. Some cars without the EGR still develop a leak, so who knows what the real story is.

I deleted my EGR and never had a problem with the manifold leaking again (it leaked once).

You say there's oil all over the bottom of the tranny, but if you feel around to the top is there any up there? If its only on the bottom of the tranny and the undercarriage its probably the RMS. Its pretty unlikely if not impossible that you'd have oil on the bottom of the tranny and not up top if you have an IMS leak. RamAir is right though that the IMS is by far the more common of the two to have issues.

Well then I feel the oily residue behind the Intake manifold.
and yes it is on the bottom of the transmission as well :/

started taking the TB of and stuff but can't get these 2 hoses off on the passenger side and don't want to mess anything up so going to read up on what they are. its 20 bucks for the gaskets so I'm going to do that anyways because it seems pretty easy to do.

One goes from the valve cover to the TB

The hose from the passenger valve cover to the tb catches any oil blow-by. Some people replace it with a little breather on the valve cover opening, some recommend against that. You can pull the hose off no problem, just either put it back on or install the breather on the valve cover and a sealing plug on the throttlle body hole.
