I have a 2003 chevy venture, blowing gasket on oil filter everytime we put oil in, it just blows gasket WHY We also replace the pressure valve that is under the oil filter, it will run the valves get quiet fast once oil reaches top of motor, then you hear a air sound and look and it has dumped most of the oil out and we find the same thing each time, the gasket on the oil filter blows out.

As you may know your car already has a dump valve, all turbo cars are fitted with one so its a matter of swapping, but beware if you do not fit a recirculating dump valve you may find a warning light on your dashboard as the ecu will register the drop in pressure as a leak, also you may find your performance will be worse, not better as the waste gases in a recirculatory dump valve are forced back in to keep the turbo spinning, so less lag

Don't do this on an Audi. They have used a recirc valve because the mass-airflow metering system on the car is telling the engine that a certain amount of air is coming, and the engine is being fueled accordingly. If you use a blowoff valve to purge excess boost air to the atmosphere, the engine will still be expecting to see this air and will be fueling accordingly, and you'll get a rich spike every time you shift. This rich spiking has been proven MANY times to degrade and eventually clog/ruin the catalytic converter and O2 sensors. Some mass-air metered cars (less precise cars in terms of engine management) are fine when DVs are replaced with BOVs, but not Audi/VW cars - using an atmospheric dump will destroy your cat and O2 sensors (plan on $1500+ to fix this).

A dump valve replaces the recirc valve. Did you see the reply to your prior post on this topic that I put up the other day? You can do it but it'll cost you your catalytic converter and O2 sensors - that has been proven out many times in the past. If you don't care about that and don't mind spending $1200-1500 every year or 18 months to replace those parts, then go to www.audiworld.com or www.audidiy.com and look in the tech areas - there are step by step procedures there that walk you through recirc valve replacment. They'll show you how to fit an aftermarket recirc valve, but you can follow that procedure to do a BOV as well.

Seriously though, as I said before, some cars are fine with BOVs but Audis are not. You're going to cost yourself a LOT of money just for the sneeze sound and slightly slower turbo spool. Your car and money though so it's your decision.

Its probably the temperature actuator located in the right rear interior

you definately should check the oil pressure switch its probobly above or to the side of the oil filter and can make it look as if the filter is leaking,it will be threaded into the engnine itself and will have a connector on the top of it most likely with only 2 wires going to it
