THANK YOU !! the only video that had the same oil filter adapter that was identical to mine again thank you made my job 100 x easier

So I was able to find plug removal sockets. Turns out it isn't 5/16" its actually an 8mm drain removal socket that is needed. If you don't wanna ruin an extension. But thank you for the video this is the only one I was able to find!!!

Yup. Thank you! yours is the only video I could find on this. My suburban has the same oil leak. I'll try to find the pipe plug socket that fits those plugs. My parts store is just around the corner.

Ditto on the only video with this adapter. thank you so much. 2000 k2500 7.4

Thanks! Was having a hard time finding info as well

I have this same project going on right now, 95 GMC 3500, 454, I’m glad I watched your video before I tore into it and realized I need torx sockets, and start yelling obscenities. 😄👍🏻

Just a quick update... Okie was right about the 8mm pipe plug, although a 5/16" works too (on .003" difference). Also, my bolts were T-40's, not T-30's. Thanks again for the vid... I expect it will help many more.. Sorry to hear about you having to do it twice..

Thank you for making this video! I have a 94 Chevy K2500 454-7.4L Silverado and it has the exact same adapter and it is currently leaking. It's a small leak, but enough I want to get it stopped. This video was the only thing I've found that had ANY information on this. Again, thanks so much, this is going to help %1000. Special thanks to all in the comments posting tools and part numbers. MUCH APPRECIATED!

Very helpful... Working on mine in a blazing 30 degrees.. The square is a 5/16".. Tried the grinding method and was able to get one out. The other was so tight I had to go buy a hardened bit. Thanks again for the post. David

5/16 square hole on my plugs. Bought a piece of square stock to use as tool.

Thanks for the video, big help! For what it’s worth, my 1992 K2500 torx bit was a T-40.

You are awesome thank you for freezing your ass off for the rest of us. I'm burning up in ft.mohave desert dying this ugh

I bought a Suburban with a blown engine. I had a puddle on the ground from the adapter the first time I cranked the blown engine over. The socket you need is a SUNEX TOOLS 310PC. I went to the parts store and demanded hex head plugs, they had Dorman branded ones. For the cooler lines, I ground the old crimps off, installed new hydraulic hose, and used some good hose clamps. I have a feeling they will work TONS better than the aftermarket replacement ones. The aluminum crimps only last about 2 years.

Thanks ran into the same thing. You did trying to figure that out. Super bad oil leak must be that gasket. Looks like I need to go find it at 3/8 extension I can grind down :-)

Thankyou!!!!my dad couldn’t figure it out

Excellent information.

Thank you for this.

Thank you I'm having an issue with finding the plug size hole.

SPOILER ALERT::: You can actually see when I show you the old O ring there’s a chunk taken out... then on the video you can see where that chunk is stick to the face of the block. I didn’t catch that before putting this whole thing back together and it leaked like a sive... man was I pissed off. Had to take it all back apart again and scrape that off but the second time was the charm: leak free! And I did delete those oil cooler lines. I plugged both of them right at the block and it worked great no issues.

Don’t forget to look into your bypass valve, I’ve found that ac delco is the one to get , a 30 lb one.

Harbor freight sales the tools you need. They actually have a set that fits this. Like 8$ for the set. For next time

Thank you!

Excellent.

I think i have a 6 gen and my seal is leaking. Looking like I’ll be doing this job too.

THANK YOU

Hey Dano, good deal on your vid. Like everyone here, you are the only source with the same oil filter adapter layout as mine. I am a 1992 K3500 Silverado. The O ring I got in a kit from O'Reilly's does not look like yours. Gonna' go to the dealer and get a factory O ring gasket. AND the big deal, would not have known about the Torx under those damn square plugs. You saved us all and those who didn't comment. Goona' get a Torx T40 and 60 to make sure I can put it back together. You a 95 and 'keep' with his 92 leads me to believe I could be either one. And, the Ol' ripoff dealer will have an exploded view on his software screen. I wonder about the aluminum gasket that mounts over the Oring and the adapter and oil cooler line connection. Did you leave it? Thanks big man!

My 1998 K2500 7.4l is exactly the same. I could not find this information anywhere else... even on the forums. Thumbs way up! Did you end up replacing your oil cooler lines? I am having a devil of a time getting them to come out from between the front diff and the engine...

I had to do the same thing

Is the O -Ring available from Chevy/GMC still as mine is leaking. Thank You for this video!

my oil cooler lines are actually leaking in my case, have you figured out if you can just plug up the 2 holes?

What’s the model number of the seal , I have the same truck and the dealership can’t even find the right seal

GM 12555554 Engine Oil Filter Adapter Seal/ O-RING. This should be the part number.

You have a part number on that gasket?

Hey I just had to order the O-ring for this and the dealership would only sell me five of them if anyone watching this video needs one
