Engine life for a 1975 BMW with ERG

Recommended Posts

Someone told me that the 1975 with the exhaust gas reactor manifold caused a 30% decrease in engine life as opposed to one with the cast iron exhaust manifold. The compression on my car is 165 straight across and I would hate to take a chance on shorteniing it's life. I recently took all my emission equipment off but left the EGR on and plugged the holes as I was having trouble finding a good cast iron manifold. Is there any truth to this or is it just a rumor. Any input?......steve

EGR is Exhaust Gas Recirculation

your dumping exhaust condensation, foul black

carbon, unburned gas, and other nasty coking

impurities right into the intake manifold.

All that clop sticks to the inside of the intake manifold,

runners, ports, cakes onto the back side of the intake valves,

that carbon caking soaks up incoming lean gas mixtures, causes rough running, poor idle, decreased power, reduced MPG's.........

get it off of there A.S.A.P.

+ extra under hood temps

cooks all your under hood fuel, coolent, vacuum hoses - brittle

noises, vibration from brackets and components.... nasty nasty stuff
