New Ground Control Suspension for the 2.3-16

We’re getting ready for a suspension instillation party here at MAT. We start at 10:00 pizza and Bevrige at noon. My new friend Rajh is bringing his twin turbo M3, 600 HP at the wheels. Should I go for a ride with him or not

Be sure to check out the second installment in our “Project 16 valve 190E. In this segment I remove the engine from the car and begin dis-assembly.

Well, my 16 valve has been sitting out on the back lot all summer and I’ve finally received enough inspiration to start the epic repair procedure in order to make it into a “Daily Driver.” Follow my video blog at the following and subsequent links: Mercedes Benz 190E 2.3-16 Project “Pulling the Tooth”

So we’ve decided to take the bitter pill. We havWe’re mostly familiar with the catalytic converter that has necessitated the use of unleaded gas since around 1975. 3-way catalytic converters break down hazardous carbon monoxide to harmless carbon dioxide. They also break down toxic hydrocarbons into carbon dioxide and water while reducing nitrogen oxides to regular nitrogen and oxygen. For the Cat to do it’s job it has to be hot which can take a while. In order to meet strict emissions standards an air pump has been added to heat the Cat up sooner and reduce harmful emissions quicker. Pump air into the exhaust and it gets hot more quickly. When the Cat reaches 400 to 600 degrees Fahrenheit it begins to clean up the exhaust. To let you know if the emissions system is working properly a number of self diagnostic regimens have been programmed into the engine management systems. One is a self test of the air injection or secondary air pump. If that self test fails your check en ... read more

Where did Flo Go?

After checking the VSV for proper operation and confirming the Air Pump actually pumps air, it’s time to dig into the engine to test the valves and clear the Air passages if possible. Removing a few choice components on the Porsche 911 makes access to the divert-er or “Dump” valve and check valve possible. Porsche uses a vacuum reservoir to help vacuum operated function during low engine vacuum conditions. It is mounted on a fixture which bolts over the air passages we are looking for. Ahhhh! there it is. The very dangerous and highly elusive Dump valve. I think I’ll make it mad. The larger threaded hole is where the check valve attaches to the fixture and the more silver colored smaller threaded hole is for the air line that feeds the right cylinder head. The check valve will be replaced even though it still passes air. More importantly shop air will be forced through the air passages in an attempt to open them so the Air can reach the exhaust side of the cylinder hea ... read more
