I'm having some issues with the hose that goes from the top of the turbo to the over-engine pipe, hopefully someone had similar issues and can provide some insight.
I installed the silicone IPD turbo hose kit that has 2 pieces, one from the turbo to the over-engine pipe, and one from the over-engine to the intercooler. I put those in around 6 months ago, at 175,000 miles.
Recently I started having problems with the hose on top of turbo. I was driving up a pretty decent hill, started to give the car a bit more gas and there was a sudden loss of power and a smell of oil in the car.
I pulled over and found the hose on top of the turbo popped off. I reattached it and drove home with no problems.
Since then, it happened a couple more times. I started to not trust the car, I'm afraid to give it any gas.
Recently, I took everything apart and cleaned it really good, and put a brand new hose clamp on it. It has been staying on for almost a week but today when I looked at it the hose clamp was halfway off the hose, I pushed it back down and it has been holding so far. The hose clamp seems to be kinda loose when the engine is cold, but once it's at operating temp it tightens up (from the hose expanding, I'm assuming)
When I took it all apart I realized the IPD hose seems too big to go around the over-engine pipe. Perhaps it expanded over time, not sure. But this seems like the cause of the problem, the hose clamp can hold it closed but I feel like the hose is "pushing out" on the clamp.
Just curious if anyone has dealt with anything like this?
