Possible turbo problem.....
 

Ok my 96 850 is about 300 miles away from having 200K on it's clock. Today while driving I hit the gas to pass someone and the turbo gauge maybe moved into the boost 1/4 of the way. Normally if I hit the gas it will almost peg the boost gauge in the cluster. Also I can't remember where the vac normally sat but it's sitting about 1/2 in vaccum when at idle or off the gas.

Is my turbo going, could it be a boost leak? I don't know how many miles these turbos get before they need a rebuild. I just got the car close to 2 months ago. Currently I could get another turbo if needed, but if it sounds like a boost leak I'll look into that first.

Do they make a pressure kit to check for boost leaks like they do other vehicles?

I'd check all the vacuum lines and connections first. I know the plastic nipples get fragile and tend to break off.

Do a good visual inspection on all hoses attached to the turbocharger, look for rupture, holes or loose clamps.

Tech, could this be a problem with waste gate stuck open?

Like stated above, check all your vaccume lines. Also, check the boost gauge line for any damages. Every once in a while mine would pop off. It would take 30 seconds to fix.

I looked at the boost gauge line first as I thought it could of been that since it's loops around most of the car but it's all in tact. I will be out looking for cracks in lines in a few minutes I'll keep everyone posted if I find anything.

The wastegate on these turbos is there a way to close them if it is stuck open?

Well the problem isn't there now.....

The waste gate opens from pressure.
Make sure that under boost the intercooler or throttle body hose isn't collapsing.
The hoses get soft then collapse under boost.
