Hello all,
Recently, my headpipe-manifold gasket on my slant six blew out for what I believe is the 5th or 6th time in the 5 years I've had the car. It became a problem after the rebuild, and the gaskets I used were asking for less torque than recommended from factory; 15lb.ft difference. And, since it was blown out anyways, I decided to run open manifold for a little while out of curiosity. Unfortunately, after removing the stove pipe, I neglected to tie off the subject of this thread, and the 3.7 liters of pure American Bald Eagles were simply too much for Canadian plastic. I have attached a few pictures of the aftermath, as well as some diagrams that I was referencing.
In the diagrams, there appears to be no listing for a "Vacuum Chamber SOP". This part was between the EGR valve and one of the CCEGR valves (located at the water neck/thermostat housing). In the diagrams, it only shows one CCEGR valve, but I have 2. Also, the diagrams show one vacuum hose from the CCEGR going to the EGR, but I have one line coming from the side of the vacuum amplifier as well as one line from the CCEGR. To me, based on the vacuum diagrams, someone REALLY went to town on the vacuum system, a lot of plastic connections all over the place, which doesn't seem indicative of a "stock" system. I'm a novice at best, so I could be wrong.
Anyways, this chamber had 3 nipples on it (two on the bottom below the valve, and one above). The two grey lines were on the bottom, and a lone black line was at the top.
Currently, I have a three way vacuum connector holding all the lines together, since two of them I could feel vacuum and the other I wasn't too sure about.
Anybody have any idea what this goofy thing does for the EGR valve? Do I need to worry about finding a replacement, because as of right now Rock Auto does not list the part and I could only find the part number on arizonaparts.com ?
Thanks in advance for any help you can provide,
