Yeah, another one of these threads, but I can't seem to find the EXACT answers I'm looking for using the search. Anyhow, here's the deal, the car is a 1989 LeBaron GTC. It has a 2.2L Turbo II. Since I bought the car it has had serious vacuum issues. The boost gauge never goes over 5PSI and the vacuum is never more the 10PSI. I had it tested at a local Chrysler dealer and they told me that all the vacuum lines were cracked and needed to be replaced to the tune of $300. I ended up buying a block and lines from FWDP. I am getting ready to install it but I am left with a few questions before I do ahead with this. After studying the vacuum diagram I figure I need lines going to the following things:
1. Brake booster - heater controls.
2. Fuel pressure regulator.
3. Boost gauge.
4. MAP sensor.
5. Wastegate solenoid - wastegate - cruise control.
If I'm forgetting something let me know. Now here are my questions:
1. I am going to replace all of the intake plumbing. What do I do about the line going to the air cleaner from the PCV? Also, does the PCV need a line coming from the vacuum block or is there another spot on the intake manifold for that?
2. I want to eliminate the lines going from the throttle body to the vapor canister. Since the vapor canister has a fuel line going to it is there anything special I need to do beyond removing the vacuum lines and capping at the throttle body?
3. What about all these check valves, filters, orifices, and this barometer solenoid? What are all these for and do I need to keep them in place?
4. What size hose should I use for everything?
I'm sorry for all the questions but I was to get this done as clean looking as possible. I also need to still be able to pass emissions.
Thanks,
Clint
