1984 300DT. At idle, I can hear a distinct "clink clink clink clink clink". Rev the engine slightly and the noise goes away. Spoke with a shop this morning on the telephone and they feel it is most likely an exhaust manifold leak at the engine. Your thoughts and input are appreciated......

It will be, it sounds like that because there's only the exhaust pulse from one cylinder.

Gee, how about taking the car to the shop and having them look and fix it? Or were you just wanting free advice from the shop?

My guess is that the person on the other end was blowing smoke up you for having the audacity to actually make such a call.

Given the pathological paranoia of the OP, I'd imagine no such call ever took place.

Great point. I errantly made an assumption.

Don't you remember? HM essentially said all shops are scam artists and can't do anything right, so he does all the work on his cars himself.

Can't wait for another few weeks of exhaust related threads from this guy.

I was just thinking about this the other day. In the past 30 years of messing around with mercedes and having had many many many indies work on them, I can only think of THREE indy technicians who actually know and understand what they are doing when it comes to german cars.

The rest are certified LOSERS.

Remember, in any given field, only 1 in 1000 actually know, understand and are WILLING to step up to the plate and perform the job CORRECTLY.

NEWS FLASH: The auto repair shop representative was not looking to acquire a new customer, thus his response.

Seems like a lot of shops don't want your business.

That door swings both ways......

Could it be the infamous air cleaner rattle caused by worn or broken air cleaner mounts?

This thread will literally go nowhere.

Don't forget to grease the screw and threads on the spring compressor.

Look up on the internet on how to use Dawn Dish Soap to make a mix like kids use to make bubbles.
My Wife uses 1 gallon of water to 1 cup of dawn dish soap to make the bubble mix for a whole class of preschoolers.

You put it into one of those pump sprayers and the Engine needs to be cold and you spray it all over the areas you think might be leaking and start the Engine and rev the Engine and look for bubbles coming out of the leaking area. Note that the shop I used to work for used the same method and it works.

Be sure to spray the wrinkled tube after the turbo and the down pipes.

It won't work on a hot engine.
