I've tried two different (brand new) LN drain plugs (torqued 19ft #) and they both leak. The original that I pulled did not. The torque spec book from Raby has 36ft# for the drain plug. That's a big difference!
Firs,t I'm going to check the calibration of my torque wrench but wanted to see if it's just me.

LN has been very responsive and we are trying to figure it out.

UPDATE
My torque wrench is not accurate!

I haven't had any issues with mine. I have one of the very early ones. I would check that there is no debris or cracks in threads in the oil pan. I always torque it to 19 ft-lbs.

I assume you're using a new crush washer and have checked that the old washer isn't stuck to the opening.

Are the threads in the oil pan undamaged? Are you using a (new) aluminum sealing washer?

I have to admit that mine slightly leaks when torqued properly. Solution - a teeny tiny drop of black 3M gasket maker on both the plug and washer seals it up good. I don't know really why it leaks/weeps and I have the latest style LN oil drain plug. But it works and then I don't worry about it anymore. Always a brand new washer every time. And I don't have that oil streak leading to the back of the sump cover. Go figure.....

BRAND NEW (never installed) drain plug and washer!

Update...It appears that my torque wrench sucks!

Which means ? Out of calibration or no good at that torque range? Under torque would be better than over torqued I think. Asking since I’m about to get that plug.

808Bill

Out of calibration. Took it to my indy and when mine clicked (25ft#) his turn two more times. Some tools NEED to work as advertised!
I'm now researching for an accurate one.

808Bill, I have been off of RL a lot in the past week or two. Whatever happened with your car. Seems like many predicted that it was AOS related, but we feared there might be internal damage with the connected rods from hydrolock. Are you going to replace the AOS or stick with the catch can? Did you scope the cylinder to see if there was any damage at all?

No issues with my LN drain plug.

I was fortunate enough to have a torque wrench calibration unit at work. I had my cheap torque wrench calibrated. It was relatively close to accurate (it under-torqued by a couple of pounds), but now is dead on.

808Bill

Been driving it to and from work and feel no issues at all. New AOS just arrived and I plan on installing it tomorrow. Still on the fence regarding the Catch (I have one) can.

Buy a …

used Snap on split beam torque wrench,
new Precision Instrument split beam torque wrench,
Avoid the electronic ones unless you use them everyday, or you need the angle feature.

A CDI torque wrench is a less expensive snap on torque wrench. It’s a snap on industrial brand. toolsdelivered.com is a great source.

How do you calibrate a torque wrench? Now I want to check mine.

Depending on the wrench, there is always an adjustment screw somewhere in the handle that allows you to fine tune the accuracy. I bought a digital torque meter some time ago and that allows me to check (and adjust if needed) my torque wrenches. Don't go overboard with trying to get it dead nuts on. If your wrench is within 3-4% of indicated value, that is more than good enough, Very often, your method of using the wrench will add more than that to the final value of the torque. Also affecting the torque is whether the fastener is wet for dry.

I saw a video on youtube from a guy who was posting videos for a living and he was doing some flywheel fastener torqueing. The final value was 90 degrees and he just eye balled it and that was good enough for him. Probably not good enough for me, but that is how much accuracy people expect sometimes.

This looks interesting. https://www.google.com/search?client...ench#kpvalbx=1
