I'll need to pick up another vacuum pump for testing....
Need to know some information, as things are scattered around:
a) Can the turbo spool up with the car in park for a test. As in, can you goose/increase the throttle and get the turbo to start generating boost.
b) What is the normal position for the waste gate: When car is 'off' with no vacuum applied to the waste gate the rod appears to be fully extended.
Is this the normal "NO" boost? (As in, with the rod fully extended you'll have no boost at all.)
c) When the car calls for "Boost": Does this apply vacuum to the waste gate solenoid causing the rod to pull back into the solenoid, and that causes the exhaust to spin
the turbo?
Some of the write ups are a bit confusing for a novice like myself. Granted I used to be a tech many years ago, but my experience is limited with turbo charge systems.
I did have the wife put the car in drive (It's off the ground on all 4 wheels up with jack stands...and we still need to figure out an ABS error) She put it into drive and increased the speed and rpm up after the engine warmed up a bit. Kicked it up and noted no boost while doing a rapid acceleration.
I did pull the solenoid that controls the waste gate off the donor car. Sadly the one end has a busted vacuum line, and it's been broken off for so long it had a spiders nest inside of it. (I can be quite curious....) We do need to replace the vacuum lines as well. Most of the lines are pretty dry rotted, but still able to hold vacuum.
Also I put a set of pliers on the waste gate arm and it does move without signs of it being seized up. (The one on the donor car was seized and took some effort to come free)
Just looking for some basic-Maybe a "Dummies Guide to Turbo-coupe Turbo's...."
Thanks all! Oh, I did locate the trouble shooting section, The website kicked back a 404 when it tried to redirect.
