I just joined Yotatech, and it was suggested I ask this question over here.

Q: Is it a simple mechanical task to remove & replace the two oil filter housing o-rings and the oil pan FIPG?

Searching first, I find my 1997 Toyota 4Runner 4Cyl 2WD (3RZ-FE) 5-speed manual, with 133K miles, apparently has seven standard places to check for a persistent oil leak which is dripping in small puddles overnight:
1. Oil filter extension bracket housing o-ring
2. Oil filter o-ring
3. Oil pan formed-in-place gasket (FPIG)
4. Valve cover gasket (incl. front & rear camshaft covers & the housing plug to the rear of the camshafts)
5. Rear main seal
6. Front crank seal
7. Oil pan drain plug washer

Checking all seven suspects, the only two that I can't exonerate are the oil filter housing o-rings and the oil pan itself, as the left side oil pan and just above that oil pan (below the filter housing) is wet with oil - however, as you can imagine, there is also oil all over the place (even after degunking).

My question is how straighforward is replacing the oil filter housing o-ring and the oil pan FIPG? Looking, it seems that it's a bolt-off bolt-on operation for both culprits. But there are often hidden gotchas (and I'm not all that experienced), so that's why I ask.

Q: Is it as simple as it looks to remove & replace the oil filter housing o-ring and the oil pan FIPG (to stop an oil leak)?

 

I see something that says Irvine on it, are you from So-Cal? I need to change this same o-ring myself, maybe I can get my mobile mechanic to do both of ours at the same time or we can tackle it together some weekend? Mine drips the couple drops each night as well...it's annoying.

 

That receipt was from another thread from another person.
I was using it as a sample of what the oil filter bracket o-ring looks like.

I haven't found a single DIY on the entire Internet, unfortunately. I'm not sure why - but they just don't exist.

So, whoever does it first will need to write it up for the rest of us, and, it would be nice to have a PHOTO of the oil filter bracket bolts (because that's what's holding me up from tackling this job just yet).

Mine too. The garage floor is splattered with oil drops.
