Hello,

I want to test if my exhaust system has any leaks. Right now, I'm having a problem because the pipe connecting the turbocharger to the catalytic converter is completely blocked.
'What do you think, can I simply unscrew the exhaust manifold in the engine compartment, secure it with a wire, and take it for a test drive? Or am I already risking a fire hazard during that test drive? The exhaust gases would probably be pushed out mostly by the airflow. On the other hand, it's also possible that after the test drive, the entire engine compartment will be full of soot. Has anyone else perhaps had this problem before?'

Best regards, Manuel.

Or am I already running headfirst into a test drive that could lead to a fire hazard?


Don't worry, it just takes a little longer for diesel engines to start making that knocking sound.


The exhaust fumes would probably be pushed out to a small (or large?) extent by the airflow. On the other hand, it could also be that after the test drive, the entire engine compartment is full of soot.

I'm starting to get worried... why are they installing insulation panels and films everywhere? Rubber and plastic don't like getting too hot.
guy...

I'm thinking of making a makeshift side pipe out of spare parts that can be attached to the door using wire hangers. It has proven quite useful as an 'emergency exhaust.'

Hi there,
Why do you want to remove the exhaust for leak testing? I can simply hold it in place at the back. Then you'll quickly hear if there's a leak.

Greetings.

Eike.

Sure, here is the translation of the text from German to English:

"Hi,"

"I also pondered that point... I think when he says 'dicht,' he means that something is blocked or clogged, which it shouldn't be."
