Using dino oil, the engine is glass smooth no matter what temperature and a lot quieter too.

We had a '99 Subaru Outback that had the piston slap because the skirts were too short. On cold days it sounded like the rods were going to go out the sides at any time. Subaru finally replaced the short block after much moaning. Our Mercedes diesel has some pretty loud nailing when cold but it goes away when warm. New injector nozzles helped it quite a bit. Keep us posted.

Yeah, piston slap has a sound all it's own. It's chunkier. Injector tap is a lot higher pitched. More like a loose rocker arm tap.
.
Joe I don't have a clue why the engine is more well behaved on Flintstone oil.
It is a lot louder under load when cold, but quieter at idle. Sounds like a jackhammer until the thermostat opens.
.
TchTchr you should hear my VW Rabbit on a cold morning.
Sounds like a bucket of rocks and the pump/cam/crank timing is dead on with about 2500 miles on a fresh rebuild, new Mahle pistons and the thickest head gasket that was available. ( I wanted the extra clearance and the slight drop in compression. Still starts right up at 25 degrees F. ) NA12x injectors and new steel lines installed with the engine.
Now it's down because the pump sprang a leak and it is out for rebuilding at Seattle Injector. It's only 24 years old. Don't know why it gave out like that.
.
Chris I'm uploading a new file that I made. I positioned the camera in the right spot to really pick up on the tapping. I'll post a link as soon as it's done.

I won't be due for another oil change until springtime, so I'll switch back over to dino and see what happens.

Ok everyone, I hope you have a good set of speakers because these audio files suck! Maybe a trained ear like Kwik's will be able to hear the tick through this crap audio.

On another note, listen to the third audio file posted on the page. I got great audio of my turbo flutter.

Sorry Lisa, I couldn't hear anything over the wind, but I'll bump you back to the top.
Dan, I was able to hear it on your second video. Almost sounds like a different engine from that angle. Thanks.

If I HAD to guess, I would say it's the #8 injector.

Kwik I'm at home and was finally able to download the video you posted. That is EXACTLY the sound of the "tick" my truck makes.
Kind of funny I turned the sound up on my laptop to as loud as it would go, and my boyfriend was upstairs. He shouted down to me and asked me why my truck was running.
Thank you.
