Oil Plug Above Filter Removal

[adf5565]

I am trying to remove the plug from the block (above the oil filter) to use as the oil supply source for my turbo but it is putting up quite the fight, even after soaking for a few days in penetrating oil. A 1/4” drive extension doesn’t fit snug enough to be able to put a lot of force on and I don’t want to strip it.

Anyone have a good technique for removing these? The only idea I had so far was to buy some 1/4” square stock to fit inside the plug as that would be more of a true fit vs the somewhat rounded cornered 1/4” drive extensions. But open to more/better ideas.

Well, I might be running into the same problem soon. The 1/4" square stock would be mild steel and twist. Seeing as the engine is out I think I would take a hex nut and set it over top of the plug and then MIG weld the INSIDE of the nut to the plug, then while still hot (but not red hot) turn it out.

I'd heat that block up nice and slow with a map gas or flat torch. That should be a tapered thread that don't like to come out.

Look for a 3/8" drive external pipe plug socket the right size. Or an oil drain plug socket set will have the right size. They will fit it tight.

The plugs on the 6.2 are 5/16". Get a piece of key stock from the hardware store before you damage the plug.

Thanks for the ideas! That makes sense that the plug is larger than 1/4". I tried some heat already but I didn't want to get it too hot so it wasn't enough to help. I'm going to get a pipe plug socket set and give that a try. It has 1/4, 9/32, and 5/16 (as well as other sizes) Hopefully it'll do the trick but if it strips I'll weld the nut on and go that route.

I will report back once I give it another try.

Snap-On PP408 is the tool the Banks turbo manual says to use. We are supposed to list current auctions on this site so you have to find it yourself. Just make sure it has the external bit.

The plug turned out to indeed use a 1/4” plug socket. The socket fit much tighter than a 1/4” drive extension did so I was able to get it out with relative ease. Mission accomplished!

Isn't it amazing how much easier things are when you have the correct tool? I've fought things for hours and hours because I either didn't want to spend the money or didn't want to wait for the tool to come in. When I'd eventually give in and order the tool, I'd have it done in minutes.
