exceptionally thick oil what do I do?

[jspaulding37918]

Since October my truck has sat in my driveway not running. I have had to change the turbos and the timing cover. And for added security I deleted the egr valve and coolers to prevent my issues from happening again. I have finally got all my parts in and installed and this morning I am changing the oil filling the coolant and buttoning up a few small odds and ends so that when I get my tuner I can just upload the tunes and go for a long drive. When I started draining the oil a big clump came out followed by a slow steady stream of really thick oil. The same thing going on at the filter. How do I clean out all of the old oil out of my engine. It is too low at this point to safely run the engine to operating temperature to thin the oil.

What the ****???

What the hell kinda oil do you have in there???

 

[08strokin]

Wow that's crazy, I've never saw that happen before. What brand oil do you use?

 

[jspaulding37918]

It's the oil that was in when I bought the truck in September. It's had water mix in with it from what I hope was just the front cover cavitation problem. I'm guessing that is what caused the thick oil. My truck was not taken care of before I bought it

I bought Rotella T 15w-40 to replace it with and next oil change I plan to switch to amsoil.

You bough in Sept.

When was the 1st oil change? Just now or right after you got it?

 

[jspaulding37918]

Just now. Bought from a dealer that was going to wholesale it and didn't do anything to it. It was my mistake for not changing it sooner but the oil wasn't thick like that when I bought it

 

[jspaulding37918]

Just to be clear though the truck has not been driven since the middle of October when the turbos failed

Fill it up with cheap oil then take it for a good drive and change it again. Might need to do that more than once.

I have heard of running a quart of trans fluid in with the oil to clean up the inside of the engine. Good idea? Or don't do it?

The thick oil is from the coolant mixing. Like already said just change it run if for a while and change it again. I have seen several do this, it need to be changed asap though.

Run thin oil, ATF is not needed. ATF in oil was an old school trick before all the good oil with detergents and such came out.
I would run a 0/40, 5/30, etc or something and go out for a drive.
Drain oil while it is hot. Repeat till you pull the filter out clean.

Very typical oil when coolant is mixed in. Here's one I drained last week. Coolant mixture.

I would pull your turbo feed and clean it before you run this motor...

 

[Bustedknuckles]

Put some diesel in the oil to clean it. If you've ever taken apart a engine that had a internal diesel leak you would see how well it cleans!

 

[DEEZUZ]

Yes and also how well it washes bearings....... oke:

No doubt. That's a slippery slope. I would personally not add diesel to the sump for cleaning. Though caterpillar allows something in the neighbourhood of 8% fuel dilution. Before calling it down. I wouldn't dance that dance though.

Cheap oil. Multiple hot drains. See where you are at.

6.4s add fuel on their own...lol

 

[DEEZUZ]

Yea, ain't that the truth.. And we can see where that gets them...


-1 for bad advice yet again

I've heard a good way to clean an engine would be to drain the oil, then fill the crankcase up with diesel. Let it sit overnight, drain, and then fill with cheap oil and run for 50-100 miles. Change filter and replace with good oil and you should be set.

Obviously, do not run it with just diesel in crank case.

But this was read on some random forum, so take with a large grain of salt. I second cleaning out the oil feed line as well, I lost a turbo from a chunk of sludge going through it.
