Above is a short video I took after letting my car sit for two days. About 15 secs into it I crank it over and there is a metallic vibrating sound coming from below the engine or so it sounds. After making the noise for 1-2 secs it goes back to normal. Sometimes my car sits for 4 days, and the sound is worse. When it sits for 1 day or less the sound is not decernable.

Thoughts? I can't really take it to a shop to diagnose, because it would have to sit for a few days before they crank it over.

Also, here is another video of my car's oil dipstick.

Watch at about 15 secs into it, after I pull the dipstick. Is the smoke coming out of it indicitive of a clogged PCV system? It doesn't look like much. The reason I ask is because I do have a small oil leak coming from under the engine but from what most people have described, the RMS leak is like floodgates opening. I've been losing a 1/2 quart every 3 months for the past 2 years, not really a lot of oil compared to what others are reporting.

 

The noise could just be the lifters bleeding down some.
Which is pretty much normal.

The smoke might be a clogged vent.

 

Next time you do an oil change put a quart of automatic tranny fluid in with the oil. I had a sticky lifter problem with mine on startups-ticking.

It wont hurt at all, and it should resolve the start up noise.

If not, it will clean your inside out.

 

Yert, good tip, I'll do that. By ATF fluid you just mean Dextrol III correct? Synthetic or standard? Keep in mind I run standard oil, not synthetic.

Tech, what type of vent would be clogged?

 

The Vent box/Crank case system.

 

OK, I plan to to the PCV vent system after the holidays, these are the same thing, correct?

Yes they are.

 

OK, just found this thread:

I also found a step by step instruction on how to do it. I get tools on Xmas, can't wait .

Thanks tech.

I use regular oil also. I just went to advanced auto parts and got the cheapest ATF they had. It's good measure for older, high mileage cars anyway.
Good luck!

 

Have you heard of any issues with using ATF oil in the engine? I did a quick search and it came back as not really being recommended, one article even mentioned it might break down gaskets and seals in the engine and cause the engine to start burning oil. Is there another treatment I can do that won't hurt the engine but clean it out? I have 140,000 miles on my 850 NA.

Or do mechanics think that it won't effect our engines? I just worry about hurting my car more!

thanks

I would never put ATF in with my engine oil. And I have never heard of doing it before reading this thread. Not saying that yert315 is wrong and maybe it works. I just never heard of it and would not do it myself.

 

I have heard and seen it done tons of times but myself I wouldn't do it.
You could try an engine flush.

 

Yeah I was thinking just an engine flush with some of that snake oil stuff, although I saw a post over on another volvo forum talking about how seafoam really screwed up the guys engine, so I'm skeptical right now. I want to clean it out because I doubt it's ever been done, but I don't want to fix it if it ain't broke ya know !

I have 142,000 miles on my car and so far so good. I just went the cheapest way to fix it, and it worked.

But whatever you decide to do- engine flush, etc- should do the trick also.

Just giving out a suggestion
