too much boost

[MikeDee]

A couple of weeks ago, I found that my intercooler was seperating from the intake. With your help, I found that I was missing the brackets that hold the IC in place, and I fixed it by making 2 out of the three stock brackets.

Yesterday, I drove my Ty and experienced a great take off with just half throttle...then the IC moved again. I added another bracket that would make it impossible to move (unless it broke metal in half).

I again drove my Ty, gave WOT and saw the (stock) boost gage go higher than I ever witnessed before, and the turbo screamed like crazy while the engine made a funky sound. I let off the throttle as quickly as possible. I then found that the IC didn't move, but the rubber piece nearly exploded and managed to move through the bracket so that it now leaves a hole to let air out.

What all this leads to, is my conclusion that I am getting too much boost. It seems that whatever was regulating my boost before, is no longer working. I read around and was wondering if this is due to the waste gate.

If so, where can I get another waste gate (I read that the stock one sucks)?

If not, what could it be? How do I fix it?

Thanks for your continued help.

get a boost gauge and see whats going on. make sure your WG solinoid is attached and that all lines are NOT BROKEN and are hooked up properly.

Agreed. Don't trust a quick visual inspection either. My boost control solenoid didn't look bad at all, but I just barely touched the part where the vacuum line attaches and the solenoid broke in half in my hands. That was my problem behind getting 20+psi when I only was asking for 15.....

If yours isn't damaged, do yourself a favor and replace the vacuum lines associated with it. It will be the best few bucks of insurance you could spend.

thanks for your replys.

It looks to me like the hose/lines aren't all connected. However, I'm not really sure where they should all go. I tried searching around to find pics (so I don't seem like an amateur) but I can't find any of what the setup is supposed to look like. To tell you the truth, I'm not really sure which part is the solenoid.

Do any of you know where I can find pics/diagrams of the setup?

Also, which boost gauge do you recommend?

Thanks for the pic. I'll let you know more when I get a chance to work on my Ty.

It's raining here now, and I probably won't get a chance to work on it for a couple of weeks, so give me some time for feedback.

Thanks again.

Thanks everyone for your help. The pic really helped also. It turned out that one of the vacuum lines was connected to the wrong place and the other wasn't connected at all.

I got new hoses and connected them like the pic. Everything seems to be working fine now. I've driven my Ty several times since, and the IC hasn't blown off. The only thing that puzzles me is that the lines have been connected wrong ever since I bought my Ty in 1999, and this sort of thing has never happened.

Oh well, it's working.

Thanks again.
