Listen to my engine

1984 300TD euro. Here's a youtube.com video I uploaded just now.

1984 300TD cold engine sound - YouTube

Since this has been my only diesel car, I really have no idea what it should sound like. It sat for 12 hours. The car was started completely cold.

I've owned the car almost 2 years now. Never had a compression test done on it or a valve adjustment. Does it sound like it needs one?

I recently changed my engine and trans mounts and adjusted my rack damper. It's pretty smooth compared to how it was before.

Sounds perfect for a cold motor!! No problems. Idle speed is a bit low it seems. Adjust it to about 800 in park, no load, and at operating temp

Two years and no valve adjustment? It doesn't sound bad, but it wouldn't hurt to add that to the to-do list, when you're comfortable with it and have assembled the wrenches, etc.

How are the air cleaner mounts? It almost looks like it's moving up and down. The engine looks like it's running smoothly, no side-to-side rocking.

Thanks guys. I have the wrenches and feeler gauges. I also have a compressing tester kit I bought from Harbor Freight. I feel a bit uncomfortable taking off the valve cover though... All those linkages... ack!

Good catch Yak. Yes my air cleaner mounts need to be changed. I have them. Just need to do it.

Tell me what you guys think about this... Once I get the valves adjusted and the compression tested and if EVERYTHING looks really good, I was thinking about getting a paint job... The hood and roof are slightly faded. You can't tell at night but during the day you can see the glossiness of the paint job is totally gone... I would obviously keep the same exact color. Would that be something worth doing? Is it expensive? I would only do this if the engine is tip top. It's almost got 270,000 miles on it.

79Mercy... How would I know where my RPM are at? I don't have an RPM gauge. Just a big clock.

As long as it doesn't ever stall, I would not worry about it. The lower it is the more fuel you save! I have mine around 650-700ish.

Between the injection pump and engine. Theres a bit of linkages that goes down there. You'll see it. Just be careful with it and

DO NOT OVER TORQUE IT WHEN YOU ARE TIGHTENING THE LOCK NUT BACK UP.

Made the is mistake in high school on my 300SD.

It sounds almost too quiet............as though the IP timing was slightly retarded. It's hard to describe...........it's missing a bit of a raspy edge that is common when the timing is spot on or slightly advanced.

You might want to add IP timing to the list after you complete the valve adjustment.

Clean the injectors

Maybe try to clean the injectors. Do a Molly Lube or whatever they call it on them.
