Thread: Built 4t65e - The results are in.

Torqued the screws in for the valve body, but before I did, I checked the torque on all the channel plate bolts. All good.



Oil pump next



Torqued



Harness was next, but before I put it in, I checked all the wires with the DVOM. No breaks



Side cover next. A little goop to hold the seal in place



It's on



I used one of the screws as a handle



Be sure to mark where the studs go before disassembly



Left axle seal was next. Make sure you have the proper tool



That's how she sits until I can fix the threads in the pan



Soooo close

let me guess your drain threads pulled clean out....

ive already fixed two with 1/2-20 heilicoils though I shoulda probably gone with the more expensive m12 to use the GM engine oil pan drain plug with the captured Oring gasket....would work great with the nice flat boss of the zzp pan.

both of the ones ive seen had some crappy machining of the pan rails....

Well, they're not completely gone. But useless, nonetheless.

I have no idea what the original thread was. I bought it used knowing the threads were hosed. Previously, it had an M14x1.5 "oversize" plug. I'm hoping there's enough material left in the hole for a standard M14x1.5 HeliCoil. My local hardware actually has generic drain plugs in stock, and a pretty good assortment of sealing washers. The plug I got was the perfect size for one of the Neo magnets I have floating around the garage.

There was some pretty bad machining chatter. Bad enough that I hit it with some emery cloth. Should be good now.

Maybe should have skipped the helicoil altogether.

We'll get it sealed up one way or another. I'm not worried.

on the TR I actually went nuts. its 1/2-13 helicoiled, I then got a flanged 1/2" uhl bolt, drilled the end for a neo rod, filled it from the bottom with rtv (get the big ****ing coffee stirrer straws) and shoved it in, I then used a std Teflon washer

McMaster is awesome.... 7/8ths hex so I can use a std o2 socket in a fix, I know, kinda stupid but this is the stupid overthinking that's gonna kill me one day

It's from ZZP:

car tuning made a few.

Those are cool, for sure. I'd be all over it if I could find one used and cheap. If only...

Got my generic HeliCoil kit today. Surprisingly fast considering it came all the way from the U.K.





And it's the correct one!



Looks like I will not be needing to pre-drill



Hole before tap



And after



HeliCoil in. She's a bit long.



Instructions say to "break off the tang." Not sure that's going to cut it.



A little Dremel action to cut through one of the coils



Plug goes in without any issues



There's even enough leftover in this coil to do another pan



Magnet layout



This should be good to hold them



And they're in





Going to let it cure overnight, then toss the pan on tomorrow

That's a good idea making the drain bolt and adding extra magnets.

I like everything I see lol. Might be a dumb question, but how does the coil stay in the pan without un-threading when you remove the drain bolt?

Not a dumb question at all. It's one of those things that, if you see it, you inherently "get" what's going on. It's a little harder to describe in words... But I'll try.

The raw coil (before installation) is actually larger (diameter) and has a finer pitch than after installation. When you screw the coil in (from the bottom using the tang) it shrinks the diameter and pulls the pitch. You can feel it kind of springing its way in as you twist. Once you quit twisting, the coil relaxes and binds itself in the hole. It's kind if like a Chinese finger trap wrapped around a cylinder. It will never unscrew (in theory) because whatever force is acting to unscrew the coil is actually binding it harder into the hole.

Did that make sense?

I got it

Ah I see, yeah because it's condensed when its new, and must be larger if it's going to spread apart and fit into the tapped threads(and shrink in diameter at the same time). As it sits, there is pressure as the coil wants to return to how it was before it was installed. Neat

I figured it wouldn't take much



and it didn't





Looks like my hardware store drain plug washer setup isn't going to cut it. I guess it's better to know now, versus after it's installed with 10+ quarts sitting on top of that plug. I'll see what O'reilly has today after work.

get rid of the copper and go with nylon or Teflon

I like the metal gasket with a rubber ring around them, they always work great on oil drain plugs.

The one on the right is what's in there right now.



I'm thinking the rubber sealing portion isn't large enough to cover the oversized Helicoiled hole. James, something like this?
