Serious loss of power
 
I am sure that my suspisions are correct, but I have to throw this in here. Today While driving in the heavy rain, my car just acted like I all in the sudden was carrying a lead brick in the back and very little power.

The rain may be incidental, but there is no turbo "woosh" noise and I suspect the wastegate is froze shut? There is basically no boost. However, the car still drives and idles smooth.

Now, this same car lost 1st gear, and I am replacing the tranny very soon, so I have been already driving the car all week starting out in 2nd gear, so to hav ethis happen basically renders my car undrivable, when it rains it pours. Tha car just broke 135K when it happened-spooky! LOL

Part II, when I got home and opened the hood, there was a smell of burning oil and hot coolant, neither are present in the engine bay leaking, seeping or other wise. My upper and lower radiator hoses are very swollen too, not to the point of exploding, but very firm, and swelling near where the hose meets the radiator and clamp.

I am suspecting multiple problems, head gasket, bad waste gate. With the car still able to start and run, that means the turbo shaft isn't broke right? So lack of boost could be explained how?

Any help is good, I am already tapped on budget for trans, now I am not sure what else I have to do and I don't expect anyone here to "fix" my problem over the internet, but if these things have happened to anyone else, what did you do to fix it? Sorry, mostly venting, it has been a bad week for me and my LGT :mad:

did you get a CEL?
check your TB hose on the TMIC
TGV's stuck closed?

Sorry dude, but all that is Greek? :confused:

SCASEYS 01-11-2013 10:30 AM

CEL=check engine light
TB=throttle body- attaches to the coldside of the TMIC
TMIC=top mount intercooler
TGV= tumbler generator valves, can get stuck closed causing power loss

branab3 01-11-2013 10:32 AM

No, CEL's, temp on guage is normal, not sure where the TGV is but I have not checked any hoses to see if a loss of vacuum is present, the car is hot and just pulled in, I was gonna drink a 12 pack and get at it, just kidding, but it HAS been that kind of day! LOL!

The car runs smooth as silk other than no boost, no misses, non choppy idle, under acceleration it lurched a bit, but otherwise very consistent smooth running other than no boost

TMIC has water in it. It came pouring out when I seperated it from the engine. It is still draining............. It is not coolant, but outside rain water, clear. So I guess the heavy rain did have something to do with it, but now, where did it get in? If it has a hole in it, then wouldn't it idle funny, or not at all? I have the stock air box and it is relatively free of water, just some moisture, I did remove the air baffle box a long time ago, and never had this problem, have driven in rain worse than this!

SCASEYS 01-11-2013 10:56 AM

do you have the stock airbox or did you switch to a CAI=cold air intake?

LegacyDan 01-11-2013 11:02 AM

im guessing your plastic end tanks on your tmic are leaking and water somehow got in, i hope water didn't get in past the throttle body as thats not good, maybe do an oil change and check for water in it or abnormal discoloration in it or maybe water got in through the intake if you went through deep water

There is water pooled up in the Throttle Body hose, Not sure if it got past that, but I have to beleive it did, there is really no major signs of water before the TMIC, so maybe the plastic tanks are leaking? There was a lot of water on the engine cover by the TMIC when I took it off.

SCASEYS, I have the factory Air Box with a K&N panel filter, the air box was pretty dry with the exception of moisture in the top, no standing water in the box though

SCASEYS 01-11-2013 11:17 AM

my guess is the water got in thru the hood scoop, which is normal
however to fill it....wow

I know, I have driven in Mosoons before and never had a problem, I shop cvac'ed the intercooler and removed any more water, cleared it from the Throttle body hose (Small pool of water) while I had a vacuum on the TMIC, I checked for leaks, it is tight, so the mystery continues, where di it come from, it has to be the TMIC, because the only traces of water were in line after it, so, I am cleaning everything and putting it together, hopefull I will make boost :rolleyes:, if not, then something else.

I think the lack of boost was due to a vacuum loss and the bypass valve wouldnt open up to allow boost, only speculating, by the way, I checked the blow off and it was damp, but moving, so I dont think any damage happened there. There just must have been enough water to lose vacuum, but enough air space to allow the engine to run. Wierd.

Fingers crossed, we are good, I shall report again soon

Thank you

also, putting in upper cylinder lube to help on the next start up, just in case

You should zip tie all the vacume hoses while the tmic is off, if it's not to late.

branab3 01-11-2013 11:57 AM

It's back together and drove around the block, still no boost, but a slightly noticeable rattling noise coming from the turbo area, I don't think its tha Catalytic convertor shield, and the wastegate armature would not move under load, :spin: I'm losing it, this car...............is going to make me nucking futs!
