Cooler air contains more oxygen per cubic inch, which boosts horsepower, and it reduces the odds of fuel pre-ignition and uncontrolled detonation. High IAT's. Coolant/Oil Overheating. Throttle position sensor - Wikipedia The intercooler lowers the temperature of the air before it enters the cylinder. How do I know if my 7.3 turbo is bad? Poor Idling. More advanced forms of the sensor are also used. It is usually located at the front of the vehicle behind the grill so air can flow into it.

As a result of these consequences, the following symptoms will be noticeable: engine power drop, jerking, difficult acceleration, increasing combustion, increased exhaust emissions. Im guessing this is normal due to the pcv system. Blocked airfilter -> vaccum in intake manifold -> sucks oil from the turbo bearings through the seals ->Seals go busted-> turbo clearances affected -> low boost. Only way to get rid of it is to do the ccv mod which you can find in the 6.0 mod section. If your sump does have the sensor you just need to disconnect the plug Next remove the two T25 Torx bolts which attach the intercooler pipe to the sump Then remove the two 5mm Allen bolts which attach the turbo oil return pipe to the sump - Some oil will drip out so be ready with your drain pan.

Internal & external wastegates are some of the most commonly misunderstood pieces of the turbocharging puzzle. which stops giving the turbo fresh/cool oil to lubricate the bearings. bwdt. The intercooler is a radiator that sheds some of this heat energy, cooling the intake charge. Struggling to cool back down. you can see oil on the intake air pipes's . I also noticed oil dripping directly from intercooler inlet hose. So far no drop in oil pressure, no smoke, everything seems fine far as the motor goes. For example, an extra "closed throttle position sensor" (CTPS) may be employed to indicate that the throttle is completely closed. When I did my heart dropped and the problem was obvious. Oil can also build up in the intake tract if there's too much positive crankcase pressure. If the oil level is too full there will be nowhere for the oil to flow, causing a build-up of oil pressure in the bearing housing.
