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.

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

Great point. I errantly made an assumption.

This thread will literally go nowhere.

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

Just like Apollo 11

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.

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.

Right after I purchased the house, the A/C stopped cooling. The house had come with a home warranty so I called the warranty company. They sent out an HVAC technician. He looked over the outside unit and then took some time poking around the garage then finally said he was unable to find the source of the problem.

He was loading up his tool box preparing to leave. I then asked, "Might you have a freon leak detector??". His reply: "As a matter of fact, I do." He then ordered his helper to go to the truck and retrieve his freon leak detector. He brought it into the garage and probed around the evaporator. The detector went off LIKE A FIRE ALARM.

Had I been the average dumb a** knowing nothing about HVAC, he would have left the house leaving me high and dry. I still think about that day wondering how many people he screws over daily with his incompetence. Remember, these people are "licensed and insured" for the public's safety.

Right.

Thanks for reinforcing my suspicions. Who ya gonna call? Not HuskyMan.

Most of these shops are staffed by lazy owners and lazy mechanics/technicians.

The guy on the other end of the telephone was looking to get out of work. It was friday, right? Who wants to work on an exhaust system? Get rid of the telephone inquiry ASAP. It's friday, who brought the beer??
