62 years old !!!!! What you sound like a young man to me but it’s great to see people age so well, gives me hope that I will be turning wrenches when I’m 62.

I give you five star. For what great job you did. Especially for this edge. We love you for you're honesty and great work we love people like you

That was one of the nicest, most thoughtful videos I've ever seen. Very thorough Thankyou...this helped me out on mine perfectly

I have done a few of these to replace the knock sensors. To make the cleaning job easier, I first use a shop vac, scraper, and wire brush to first remove the dirt. If you remove the dirt first, the oil comes off real easy with brake cleaner. If you hit the dirt with brake cleaner first, it makes the dirt into a muddy slurry and it takes so much longer.

Thank you very much for the time and effort it took to produce this. It was very helpful.

Awesome walkthrough! I really needed it. I picked up a 05 Z71 Suburban 5.3 with 217k miles and I have an oil leak. I believed it was the oil pan gasket. After replacement, I still have a minor oil leak. Now I have a list of parts to get the job done. There is nothing worse than doing a job and missing something small needed to do the job correctly. Thank you!

Great Video. One of the best I have seen.

damn I need to do this job on my tahoe in the spring. Guess I need to compile a list of gaskets and new parts. Looks like replacing everything all at once is the best move. Thanks for the video!

5⭐️bud man. Great job. Thank you

Of course i come across this video AFTER i had my intake manifold off to replace my cam position sensor, oil pressure switch and knock sensors all in the same search for that elusive oil leak from the back of the engine. Replaced everything you spoke of except the valley pan gasket amd still have my leak. Time to do it again.

Great vid. I went to take the valley pan gasket n the 2 back bolts were loose😡😡 hopefully that fixes my oil leak👍👍

This is the video I been hoping for! What a great job. Thankyou sir!

I noticed I was burning some extra oil on my 04 Sierra w the 5.3 and that it had a lot of buildup around the valve covers and under the intake plenum. After seeing where yours is dirty I think my valley pan gaskets shot too, this vid will definitely come in handy, thanks!

That's very encouraging! The way you describe yourself, you and I are about the same physically and agewise. You're a little younger. So I ought to be able to do this job. I only wish I was at home with my garage, instead of 1150 miles away in an apartment. It's a lot easier when you can just stop and clean up and go to bed and then resume in the morning. Here, you can't leave parts and tools lying around, or they'll walk off. Heck, the whole truck almost walked off one night. I wish it had! If I'd known I was going to have so much trouble with this truck, I would left it unlocked with the door open and the key in the ignition. A thief deserves such problems, but not me!

Man my 2000 silverado with 215,000 miles looked exactly like yours with rodent feces and gulf coast sand included. I cleaned mine just as you described with a toothbrush , B12, and paper napkins and some mystery oil when the fumes got too heavy all the while trying to keep debris out of the intake ports. I thought I had a rear main seal leak but now that I look further there seems to be oil on the back of the transmission.

Many thanks for uploading this video. About to take on the exact same task on my 06 4.8 your presentation is more than I could have asked for and I found your video very informative. I thank you once again!

Awesome video! All the info you need to do this job. Amazing how you got everything so clean. Great job

Wow. Awesome Video. Great description and pictures.

Great job! Looks really good! I am actually doing the same thing to my 03 surburban lt. Lots of work and hours like you said.

Great video.... You got that clean!... I agree while you have it all apart replace the stuff... I gave you a thumbs up.

Great video, I was just about as clean as what you did. Great detaul on the Valley cover!

Just completed, I had 4 ports that were leaking. Replaced valley pan gasket, knock sensors, cam sensor, valve cover gaskets, steam vent gaskets and intake gaskets. truck runs like it was brand new, Next im going to install a oil catch can. could not believe how much oil gets returned to be reburned from the PCV valve, soot everywhere.

This was great, I used a lot of this for my 03' corvette which is basically the same thing.

Good job cleaning. I'm chasing leak in the rear of my 2002 4.8. Just got the tranny out. I'm going after: rear seal plate, valley, sending unit, & knock sensors. Already had replaced valve covers.

Very well explain Sir much respect thank you

I actually would have liked seeing u clean all that because I have a similar situation only maybe a little dirtier and I’m scared to get any into my engine

Awesome video. Thanks for sharing it with us. 🇺🇸

Thanks , great narration .

Good video. I have an oil leak in my 5.3 and this gave me a good idea of where to look at

Great video!!!

Great video! I'm not taking anything away from that! I just wish it was a little bit more detailed in the teardown process. Not complaining much, I still learned a lot. Thank you very much. Much respect.

You did a great job, looks awesome

Great video. A lot of cleaning. Looks great.

Great job! Need to do the same to my truck. Thanks

Wish I had seen your video before I tackled my knock sensors I made so many mistakes that I could have corrected

Incredible video!

Did mine yesterday. Very helpful, thanks.

This video was very helpful, thank you!!

Excellent video 2 thumbs up brother!

Excellent video thanks getting ready to do mine ....big help

Awesome video

Great video good information !

Oh god, now I’m scared to do mine 🤣

Awesome job. I just bought a 2001 Silverado 4.8L and I've got lean codes. Pretty sure it's the intake manifold gaskets. I'm going to replace knock sensors while I'm in there. What else do you recommend I replace while down there?

Question when you removed the valley cover and you said the coolent bypass pipes did they leak when you disconnect them???? Will I need to add more coolant? I'm replacing the oil pressure sensor, camshaft position sensor, knock sensors and wire harness, Valley pan gasket. And valve cover gaskets. I already did the intake manifold gasket last year. I would love to get everything cleaned up.

Recently had my valley cover gasket replaced but they used the old coolant bypass lines. Worst of all they didnt put the metal spacers/gaskets back. Im pretty sure one of the ports is leaking significantly now. Could that be a possible problem for electrical issues at the back of the block? Considering thats where the engine ground is?

excellent video

Just took my heads off how on earth did you get that soooo clean!?

Nice Job!

Thank you for making this video. Excellent job! Did you use a over the motor raised platform creeper to do it? Your back must have been killing you otherwise. Is it your daily driver?

Wow nice video

Your my hero

What did you clean the intake valves and valley cover with ?? Carb cleaner ?

Great job!

REDUCED ENGINE POWER. Suburban 2003 Tokyo

Great Video, Mine is 2004 5.3 Aval and so far I don't see any issues with oil or Dexcool. How many hours it took you to complete the task. Again good show.

Did this fix the oil leak? I'm having the same thing happen

How did you get everything so clean with the ports still open? brake cleaner okay to get in those ports?

Good 👍🏼 job looks nice

hey did any of the leaks come back after doing all these repairs?

Does the throttle body butterfly supposed to have some play, i mean when took it out to clean it and pushed in, it went in about 1/4 inch

even though you won't see it you should of sanded and repainted the valley cover silver..

Anyone know why my valve covers are caked? Between coil packs and top of valve covers? Both. From front to back.

Gonna post a update video anytime soon?just curious if u found the leak

The best way to work on a truck this size is to take off the front wheels, you'll have better leverage...just my two cents 😉

Maybe u get this and hopefully can respond those intake gaskets do they work i ordered some and I was thinking that the steal shouldn't go between the heads and intake but how's it going 5 yrs later

How did it run after the clean up job?

What did you use to clean all that?

👍👍👍👍👍👍👍👍👍👍👍👍👍

Where did you get the torque specs for the valley pan that I cannot seem to find them anywhere ?

Great how-to.. thank you for the effort of making your video. You need to try CBD oils for your arthritis topically and internally it helps my arthritis. Another good oil my sister-in-law introduced me to is Copaiba.. keep up the good work sir

Holly moly that is bery nasty

U ALREADY A NEWS GUY U JUST DON'T KNOW IT. I HAVE SAME OIL LEAK ON 6.O. DID U FIX UR OIL LEAK PROBLEM ? GIVE ME A HOLLER.
