Started cleaning sludged engine

Campaign to make this a sticky?

 

[NGAneer]

so my wI've was driving to work in the tahoe today. I told her all the stuff to keep an eye on. oil drips, oil burning smell, oil pressure gauge, oil lights ect. she calledencouraged in a panic, and told me the oil like came on.. I had her check the dip stick, and it was full. I was like crap. your only 5 miles from the house, drive home. I left work, came home and it was a cel for the knock sensor... haha oh you!

So you put in the knock sensors you bought, right?

 

[Jon Chimpo]

No, I'm doing one thing at a time. I want to go through it and do one thing at a time so I can note any reactions, and what I did to cause it.

The knock sensor will be going in soon, as it's come on a few times now. I wasn't sure if it was coming on due to the sludge, or if it was just faulty.

tranny service some time this week, along with the diffs, and T case.

still working on that fuel filter.

the brake fluid is pretty nasty.

coolant system needs a flush.

TPMS sensor needs service. I'll have to take that in to a tire shop.

Then I move on to suspension, which I knew needed a refresh. It's creaky, and clunky.

So how much was this thing when you bought it?

 

[Jon Chimpo]

I think we paid 8k, plus tax.

I knew it needed tires, suspension work, stepper motors when I bought it.

whenever I buy a car, I change all the fluids regardless if they are up to date or not. So I don't count the cost of fluid into my price.

$8K OUCH! See that Black 05 Yukon Denali to the left... I paid $2500 for it and drove it home. The frontend was shot and the Throttle Position Sensor was acting a fool. Around $500 later and she runs like a champ. I rebuilt the whole frontend bushings, tie rods, idler/pitman arms, ball joints and all. I might end up having to replace the steering gearbox if I cant adjsut the slack out of it.

Well congratulations. In my area the cost is 8-12k with the miles, and options. I wanted the Z71, that upped the price. I also wanted white, that is also a premium. The rear captains seats were a must have.

So far in into it for about 9,500. I already have my fluids, and sensors. I figure another grand in suspension, and we will have this thing for many years.

At the end of the day we like it. I think i was able to revive the motor, so cost is really a moot point.

Don't forget the rtv beads when you do those sensors.

 

[Jon Chimpo]

Don't forget the rtv beads when you do those sensors.

Yes sir, I saw and watched a few videos on that fix.

 

[Jon Chimpo]

All in all I'm pretty happy with how it came out. time will tell how well that motor runs. After a day of driving no noticeable oil loss. No drips.

I park it in the garage, in the same spot and check the oil first thing in the morning before starting. I'm taking photos of the oil level so I can compair.

10-4. Just curious considering the work it needed.

Well the sludged engine was a surprise....

Cordell. Where are you from? I've have a few vehicles try and flip out their You try the H2O on the fuel filter nuts yet? If you're getting a single knock sensor code you may be in the clear driveability-wose for quite awhile - best to work on the more pressing for sure. When you do get to them I sealed mine in an 01 yukon about 75k ago with layered LIQUID ELECTRICAL TAPE all the way around including the harnesses - WAY better than RTV and it lasts forever. Good luck with the build, i'll check back for updates.

haha! Sure it seems I've been getting the short end that last month ever since we did our taxes.

 

[Jon Chimpo]

just did an oil change after 100mi with the seafoam. Oil came out real black, with chunks. Filled it with straight Valvoline, and a wix filter. going to run it and just monitor oil. and not mileage. it still hasn't dripped a drop of oil, or no noticeable oil loss.

 

[Tonyrodz]

I wonder when the chunks will stop.

 

[HiHoeSilver]

I bet running some Kreen for 500 miles will finish off those chunks.

 

[iamdub]

Yes. I think he should run another short OCI with cheap oil and filter and a good cleaner, such as Kreen. But, he's doing right by monitoring the oil and not the mileage, so it's likely to be a short OCI anyway.

Regardless, I have a positive feeling about the outcome of all this.

 

[RED TAHOE LS]

Over the years I've added a quart of kerosene to my sludged up engines and let them idle for about a half hour and then drained them with good success. DO NOT drive them with the kerosene in them though as it reduces lubricity somewhat.

Times two on the kerosene which is an ingredient in diesel fuel. A couple of drains will definitely do the trick, and no need for top quality oil, since your draining anyway. Good luck and follow up when finished. JMHO

When its done throwing up....
