Ls 460 motor oil leak
#61
I'm guessing the oil is leaking from your filter housing. I also had this problem a few times with oil leaking down the filter housing. It leaks from the very top. I can see how it might look like it's coming from up above. I recommend purchasing a genuine toyota ( lexus) metal filter housing. Then only use the genuine 0-rings. I've found a few aftermarket orings on ebay that did not seal properly. They caused a slow to mild leak.
I tried an aftermarket metal filter housing from autozone. It worked fine for 5000 miles. Then on the next oil change it leaked. I believe the oring included with the aftermarket housing sealed fine. The subsequent orings I tried leaked.
If you already have the genuine metal housing I'd replace the top oring with a genuine one, If you have the plastic original housing it may have cracked which is common. In this case also replace it with the genuine metal housing.

Is it hard to see a cracked plastic filter cap? Contemplating whether to swap it to metal / aluminum ...

Allusuc I would focus on once thing at a time. First thing is the fuel pump gasket leaks. Are you sure they are still leaking and on both the passenger and driver sides? Can you tell specifically where they are leaking from? Can you post a picture of the leaks?

my fuel pump gaskets aren’t leaking anymore. I cleaned the area on the metal housing/cover really good. And looked at it after driving around a block and there’s no leak coming from the fuel pump gasket. But it’s still leaking somewhere.... because I see 3-4 drops (size of a quarter) on my floor. Ugh so sad. Dunno what to do now

Ok well good job on the fuel pump gaskets. It is good to hear they are not leaking. Have you cleaned the filter housing and area around it really well to see if you can isolate if the leak might be coming from there?
#65
you know ... it might be from the filter cap itself. The black filter cap. I know the old owner took it to valvoline to get oil changes done, and they might have over torqued it to where the cap it is warped? I know the two o rings are on the filter cap correctly since I changed it myself. But honestly; is there a high chance that the filter cap itself, is bad? Hence causing a leak (even though o rings are in place)?
does anyone know the part numbers for the filter cap?

I have this oil filter cap part #15620-31060. It is an aluminum Toyota filter cap and not the OEM plastic one.

Also for anyone interested, this filter wrench is really great and worked on my old plastic filter cap that had rounded angles and broken plastic tabs.

I found this one. Looks same, but cheaper. Anyway, did you do any modifications to the middle metal part since it’s shorter?

Looks like this is the part# 96722-24030 and may be cheaper from a dealership? Or like 305Busa did in post #4 and found some that matched. But then again, you'd have to remove the old ones first. 8(

Check out these oil leak pics!! At first I thought it was oil filter cap (might still be), but it’s this metal part on the right of the oil filter cap!! Is this the part everyone was talking about? Needing the 2 o rings? Also... I didn’t notice until I zoomed in, but it looks like it’s freaking cracked!! Is this true!!!??
Zoomed into the picture. See the far right? It looks like a freakin crack!! Omg!!
First glance. I see oil on the filter cap. Still might be this, and I’ve already ordered a metal one which I’ll install shortly.
Another pic. Oil seems to be coming from that metal part.
You see there the light is shining? Oil is coming from there.

Allusc. Here is a picture I just took from my car that mostly matches the angle of your picture above. The bolt circled in red in my picture is the same bolt just above the oil filter in your last picture. To me it looks like your leaking may be coming from the area I circled in blue and from what I can tell that looks to be where the timing chain cover attaches to the block. You may have a leak coming from that area, but it is hard to tell.

to be where the rear plate attaches to the block. You may have a leak coming from that gasket, but it is hard to tell.
