D.I.Y. oil change o ring kit

[irvin48]

I've reused the washers and have never had a problem. I do change the o rings. Use Baja Ron's products.

Bored at 2am, accurately measured with a digital vernier caliper, and the large cap O ring ID checked for roundness and accuracy on applicable tooling.

As I mentioned earlier, none of the oem O rings are typical black nitrile material. As can be seen, they use a soft silicone type and high temp Viton type.

Small drain plug gasket is copper, large drain is gasket is aluminum.

Forgot too how many drain plugs I accumulated when dimensionally checking them on account of failures. Have two sets of Dimple Drain Plugs, One set of Gold Drain Plugs, and a set of oem drain plugs. Ironically, others have stated aftermarket drain plugs fail, yet no issues here and, when I was doing the comparison, I was handed a failed oem drain plug.

What does it mean...likely the torque spec is for a new engine with clean dry threads, and second, if you must torque your drain plug, adjust accordingly for a wet torque AND, be certain you have a good or excellent accurate torque wrench that you are properly using. This means correct range markings and set correctly.

All the best with your quest to save a few dollars, I get it, but certainly hope you get the correct type and material O rings. Never fun finding melted, swollen O rings or worse, split housings from excessive expanding force.

Spot on regarding the seals and torque. Any residual oil and you are basically lube torquing which will reduce the required torque. By what percentage, I don’t know. Need test equipment for that. I found this site to be a pretty good place to dig deep into all that is engineering.

I replace my seals because it’s good maintenance practice…for me.

Metal bonded sealing washers

Concur with metal bonded sealing washers for the engine/transmission mating surfaces. I use a 1/4" digital torque wrench and stop when the warning light comes on (ie before the full torque sonic alert) using service manual torque values. Works a treat.

What are the implications of one of the O rings splitting under pressure on the sump bolt or filter thingo though Mike.They seem like a fancy design for some reason to me. Could be the first indication of one letting go is a rattle :dontknow:ray: For a few cents and an easy change why risk it?

A few cents ???? .... you just quoted $ 173.00 !!!! ... AND the oil drain plugs will NEVER rattle, if yours are there's a serious problem ..... those rubber " O " rings are for oil leakage, not to prevent Rattling ..... good luck ... Mike :thumbup:

Was supposed to only be a few cents if I could have sourced what I wanted but unfortunately not to be.
Was more concerned as to the o rings deteriorating over time and maybe:dontknow: causing an oil pressure drop , starvation of some sort, incorrect oil level reading or my thingo to turn green.:yikes:
Those drain plugs are a weird ass design that I don't fully understand so caution is the name of the game.
For a bit of context, just for an experiment Mike next oil change you do leave the o rings off all together simulating a failed one and report back to us if you hear a big end rattling after a few miles:joke:
Washing grease off my hands in unleaded is my sort of risk but I draw the line at reusing rubbers:wrong:

If oil drain plugs rattle there's a big problem.

If any of you are regulars at your dealer try asking the mechanic if he has any to spare. Sometimes they seem to have extras!!

Like many others, I don't change mine out very often.
