right, hissing/leak located, it was the hard black vac line that should go to the check valve, couldnt get it back into the check valve, so its plugged straight into the recirc valve (is that going to cause a problem?) anyhow, hissing/leak rectified, i did take it around the block, but it was end of school run/begining of rush hour time, am going to take it for a blast in a bit, and report back

If the line goes to the recirc valve without going through the check valve then the recirc valve will see boost which is not good.Comment

so this turned out to be an air leak then... Let us know where the vaccum on the guage stays now that you have fixed it. Is it lower or higher than before?

My next step is to check the backpressure of the exhaust from the downpipe niple, have an extra boost gauge but have to buy some hose to make the connection to the downpipe for a few test runs.:mischeif:

but the recirc valve is vacuum operated, not designed for pressure, so might possibly break. Thats why I just plugged plugged the line. Its a mystery how this got to be like this eh?
