Man like my son did he got a 5.3 from a junker pulled it out and all apart resealed everything over time and extra money gave him experience lapping valves and shit like that. Redid all the gaskets and new exaust bolts and basically everything so when the current engine he has quits or gets real bad hes got a backup in the garage on a engine stand ready to throw in. Only problem is these things just don't quit! They are good engines and will run broken in many places. its just way easier to have the engine out for a reseal cuz its a battle otherwise.
I like your style. Everytime I see one I want to collect them as backups. They are fun to reseal when they are out. You never really know the condition when you get one used lol. He sounds like me.
Thanks for posting this! I need to find my leak. I am just replacing o rings and gaskets one at a time till i find it😂 its somewhere on the rear engine. But i dont think rear main.
Thanks Matt. Great video with lots of info. I've suffered almost all of these leaks. One of the most annoying ones is the 4L60e to transfer case. It can leak! And if your seal is truly fucked, the transmission can pump fluid into the transfer case!
Matt, actually the trans lines going into the radiator go Into the trans fluid heater, it's a small core designed to heat the transmission fluid on cold days. You can get a trans cooler off of the GM 2500 series. Your truck has the bolt on adaptor in front of the radiator. The best way to change everything you mentioned is pull the engine. You can change to oil pump pickup tube O-ring, the rear block plate gasket, and the rear main seal, easier, if the engine is out in the open. I'd change anything that's hard to get to. My 5.3 has over 420K miles, and runs as strong as the day I bought it new. Mobile 1. . 10w30. Mobile 1 trans fluid. I use Amsoil rear end gear oil. and AC Delco transfer case oil Part number #10-4017, you can get O'Reilly's to order it for you. 👍
Thanks for the vid. My oil cooler block off plate, oil pan, and rear main have been done and I still have some leak from the bellhousing area. Hope I don't have to try to do the rear main again, lol

Great vid. Subscribed,! Ive got an 8.1 in my truck. Its burning off oil on the passenger side manifold and also drips a bit of oil. I think its somewhere near the top of the engine but cant locate it.
I have the same truck and changed the rear main seal and new oil pan and its still leaking very little not on the floor but by the oil fliter and the sides of the oil pan/rear main seal
I got rebuild cammed 5.3 it doesn’t leak but it burns about 1 quart in between oil changes I’ve met with many mechanics and they all said it’s normal I’ve never really had to add oil till like 3,500 miles and do my oil change between 3,000 and 3,500 my oil is not really dirty at all it’s clean for the most part but I’ve seen people freak out over burn oil it’s normal I would assume
@@MattsShop and I don’t lose oil but I do lose oil over the span of 3500 miles but it’s a quart of oil if it was a leak it would be more but yeah man I wipe it down and nothing comes back on the cover I don’t think it’s oil
If Chevys are a piece of junk then I would be curious to know what cars or trucks you think are better. Don't get me wrong, some Chevys definitely are junk, but the GMT800s are simply some of the best all around vehicles to ever enter the market.

You're welcome. It's always a couple of seals/gaskets once they get old they all seem to leak! That oil cooler block off plate is easy though.
@Anthony-du3he Check your oil pressure senser. Mine is leaking pretty bad. If you have oil on top of the transmission case that might be why.
So enjoy ALL education. My Silverados are 95 6cy and 91 Z71. Both are great trucks.
Thank you for your tips.
You're welcome that's a pretty rare combo, most of those were 5.7 V8s
Thanks for the leak location's
You bet 👍
Good stuff Matt. 02 2500HD 6.0 LQ4 400K+ miles. I aint letting go.

You're welcome! I know those 4x4s can have a lot more leaks. The transfer cases on these trucks seem to give people a lot of problems!

Thanks man. Yea, check those sensors on the top of the engine. They normally have o-rings that can leak.
Thanks man. I will and report back!
The seal at the bottom of the oil fill tube... Do you need to get the valve covers off to get at the bottom seal?
I have the same truck and changed the rear main seal and new oil pan and its still leaking very little not on the floor but by the oil fliter and the sides of the oil pan/rear main seal
They always leak! Just too many different angles to seal up. It's not a problem unless it's a lot!
@@MattsShop it never leaked before

Matt where is your shop located?
Where do you order the new valve covers, can you send me the link
You can get them anywhere get the GM genuine or Dorman valve covers. Iook them up on Rockauto for your vehicle.
I checked my heads they are kinda of dirty is it always oil or is it dirt or grease
It's oil with dirt stuck to it 😁
@@MattsShop yeah buts it’s on both sides of the block I don’t think it’s oil because I wipe it down and nothing comes back
@@MattsShop and I don’t lose oil but I do lose oil over the span of 3500 miles but it’s a quart of oil if it was a leak it would be more but yeah man I wipe it down and nothing comes back on the cover I don’t think it’s oil
None of them. That’s why we have mechanics like you. 😄😄😄
I thought it was horsepower sweat.
It is lol!!

So don't buy a chevy...got it.
You must be fun at parties.
@@goliathonline69 It's a joke!
chevy more reliable then dodge and ford tbh
My opinion Chevys are a piece of junk major project car or a truck
Everything mechanical is a project lol!
Got an 08 with 322,000 miles. No issues. Depends on the person keeping up the maintenance.

Seals leak ? With heat & age. 1 or 2 table spoons of brake fluid each oil change will keep the seals soft, yur welcome. 🫶🏻
Do you do that to the engine oil? Never heard of that one.
Works on steering pumps, that’s where I 1st used it, put in the oil, brake fluid IS oil.
