Auxillary Valve

[macruadhi]

I have been told that one of my "Auxillary Valves" may have been burnt or somehow been rendered inoperable. My question is, has anyone else heard of one of these? Autozone has, but they don't carry it. The closest the Mitsubishi can get is a "Check valve" located somewhere on the block. But I'm quessing that's not it. Thanks

DSMs don't have any auxiliary valves. What are your compression readings?

They'll occasionally burn a valve, but most valve damage comes from timing belt failure.

Now you can tell us the rest of the details.

Compression is 180 psi with only 3-4 psi deviation.
