This pan gasket was replaced once before, fairly recently by the looks of the gasket set. I suspected a friend crankshaft seal may also have a leak. I’m going to reseal this pan again under warranty, get it super clean and we’ll do a recheck next oil change.

    One thing people don't necessarily think of with the whole "EV Debate"… no more oil-stains on the driveway! We had to replace the rear-main-seal on our 83 Chevy Blazer… it was *not cheap*. 🙁

    Old fart advice. Keep some thread handy. Tie about 4 holes loosely on pan. As you start getting situated just cut the thread and remove

    I had same problem on my 98 Chevy Silverado and it was the Timing Chain Cover, the mechanic said that the oil pan must be dropped to repair problem. He did all that work and it is still leaking and will not talk to me about re-doing the job so I will have to pay someone again for same repair and another $350 dollars….

    My chevy truck has 300 thousand miles on it and it runs great. I think the leaks are what keeps it going, always has fresh oil . lol I still change it when im supposed to .

    You know, Ray, for someone who says that they hate "Brake Clean", you sure do use a lot of it………😄. You obviously hate "not shiny" more…….🤣. 👍

    Reeeee, I think if I owned this I'd have been like "let's see how much she leaks after screwing the oil filter on…"

    I am soooo jealous. Just look at that absolutely beautiful undercarriage. Clean, shiny and no RUST.

    An alternative trick to holding a gasket to a pan is to use 4 loosely tightened zip ties, which once the pan is offered up and finger-tight bolted, can be snipped and slipped away.

    Just about every car I owned over the decades had some sort of an oil leak , just goes to show you gaskets don't hold up no matter what they are made of . Go figure !

    OTT packaging for that O-Ring

  21. Avataaar/Circle Created with python_avatars Paul Rollason says:

    Is it brake cleaner you use to clean up any oil ?

    Did a little mechanic work in the ‘70s with Porsche /Audi / VW. It was fun for several years but moved on to a totally different career. I thoroughly enjoy these videos. The fact that you are extremely knowledgeable and confident in your abilities is greatly appreciated.

    One of the thing please stop mimicking that damn phone ring it's annoying.

  24. Avataaar/Circle Created with python_avatars Gregory Woodcock says:

    It look like it to me that the oil filter was loose and causing a leak, I'm a machinist I also work on cars ASE certified and from what I seen there was no reason to replace that gasket, when I seen was a leak from the oil filter, I feel like if you were charging them I believe you were ripping them off. But if this is under warranty I think the warranty problem was the oil filter itself.

    I kind of missed the click.

  28. Avataaar/Circle Created with python_avatars Spixy cat says:

    So what was the reason of the leak? Could be that it was not the gasket. Always nice that you found the problem and fixed it

    And, comments about the others who've commented here about the mm vs thousands of an inch argument. One commented that you couldn't see a 0.007" warp with the naked eye. Well, if you can't see 0.007" with the naked eye then, bottom line, YOU Must NOT be a very good machinist or mechanic!!! Matter of fact, IF You cannot see a 0.003" gap on an exhaust valve, get outta my shop! And, when it does come to mm vs thousands of an inch, you people are arguing over "0.2" mm conversion, how about converting 0.0000125" to a mm answer & let's see how many need to pull that answer outta their butts, or go buy a bigger calculator (made in China). Isn't if funny, how "We" the USA had to win a war in Europe, FOR THEM, & beat the Rice Burner crowd, only to succumb to THEIR forms of measurements???

    I think the headline of this video shows why "shop mechanics" never permanently Fix a oil pan leak problem. Why is that? Well, let's start with the design of the oil pan gasket with built-in sealer. How many "shop mechanics" tell you to come back in a few weeks AFTER the vehicle has gone through several heat up, cool down cycles? NONE. Yet, the design of the oil pan gasket relates directly to the need to re-torque the oil pan bolts after several expansion contractions of the metal mating surfaces ( EVEN THO the gasket makers "claim" otherwise). Try it Yourself with a "lifetime warrantied" gasket. 1st thing the gasket maker claims when their gaskets fail is that the torque isn't correct on the bolts & the Reason for the leak.

  31. Avataaar/Circle Created with python_avatars RealClass American says:

    #1 Question: Who Fixed the oil pan leak the 1st time for it to leak, so soon, again? #2 Question on the install (which, if done in exact sequence of this video is WHY it leaked again). When an engine is built from the factory, the oil pan is installed onto the engine block "1st", THEN the transmission (Bellhousing) is attached. So, WHY did he torque the 2 bellhousing bolts up Before torquing the "Sealing" oil pan bolts? Seems to me, once torqued to the bellhousing, torque on the rear oil pan bolts will Not be Correct & a perfect formula for a future oil pan leak again. After all, there is no oil sealing going on at the bellhousing, Unlike other styles of oil pans where bolts from the timing cover, which is Oil Sealed Also come into play. I guess he is going to say that if the pan is torqued to the block 1st, when the 2 bellhousing bolts are torqued it will pull the pan back. The Proper method, is to torque the bellhousing bolts, then back them off just enough to allow for Upward movement of the oil pan, torque all oil pan bolts, then re-torque the 2 bellhousing bolts.

    they way a dealer deals with these oil pans now is with right stuff silicone seems like a lot of GM aluminum blocks dont have flat decks for the oil pan

  34. Avataaar/Circle Created with python_avatars Paublus Americanus AMERICANUS says:

    Why do you suppose the customer did not want the light attended to. I can check my own engine lights but do you suppose his is just an evap leak? Good job on this oil change Ray.

  35. Avataaar/Circle Created with python_avatars Chi Chu says:

    GM cars most models always have some kinds of leaking oils problems.When it getting old around 100k or more on the car odommeter.

  41. Avataaar/Circle Created with python_avatars Daniel Clements says:

    If that o ring on the pick up tube was that mangled. Could it have leaked back into the oil pan and put pressure on the oil?

  42. Avataaar/Circle Created with python_avatars Ray Vandegrift says:

    Just curious. Do all LS's come with a real chain for a timing chain or do some come with a belt and what is the purpose of the plate on the bottom of the oil pan

  43. Avataaar/Circle Created with python_avatars Jason Jones says:

    is there a reason that the block mating surface was not cleaned before the pan we reinstalled? will the leftover residue impact the seal of the new gasket?

    Just curious, I thought the gasket sealed all the way around, so what is the reason for the silicone?
