DIY '96 - '00 Replace Oil Pan, or Reseal Oil Pan Gasket

I just posted a youtube video for the DIY of re-sealing the oil pan gasket, or replacing the oil pan for the gen-1 Rav4. I had to replace an oil pan because I encountered a stripped oil drain plug.


The job is pretty simple -- you remove the plastic shield, remove one section of the front exhaust, remove a stiffener plate/bracket, and remove the oil pan. The oil pan gasket is FIPG (form-in-place gasket) material. I used Permatex Ultra Black, but I showed the Toyota p/n from the FSM, for those who don't have 24 hours to let the Ultra Black cure.

There are two different exhaust set-ups for the USA Ravs: California and Federal/48-State. There are slight differences that I mention in the video as best I can. The Rav in the video is a Federal emissions '98. Anyone who knows more about the Cali set-up, please chime in.

There is a gasket for which I just couldn't figure out the Toyota p/n (US Federal/48-State version). It is a graphite/mesh wire donut exhaust gasket that fits at the spring bolts connection to the intermediate pipe from the manifold (the front-most spring bolts for the Federal emissions version). It is not the same gasket as the spring bolt donut found on the California exhaust, which is Toyota p/n 17451-74051, or Fel-pro 61106 (2.4" ID).

The best p/n I could find was aftermarket, Walker Exhaust #31614 (OD 2.6", ID 1.94"). I bought that, but after inspecting it, I ended up re-using the old gasket because I didn't like the fit of the Walker item. Here is the location of the gasket:



If anyone happens to know this gasket, either as Fel-pro or other aftermarket, or especially as a Toyota p/n, please let me know and I'll add it to the description and comments of the youtube video.

Thanks!

Thanks, eodgator. Yes -- the Fel-Pro gasket is an option too, that is the rubber-cork material like Toyota uses on the automatic transmission pans. I used Permatex Ultra Black for the oil pan gasket (it is a form-in-place, like the Toyota FIPG but it takes longer to set). I've used it before and its great stuff, though it is true that you can really make a mess with it if you're not careful!

Did you have any issues with the cork gasket?

Also, do you remember where you opened the exhaust? No chance you have a part # for that exhaust gasket at the spring bolts? Or maybe you opened it up at the very top connection?

I replaced mine with the Fel-Pro OS30468C Oil Pan Gasket. I cannot find a oil pan gasket made by Toyota, if I remember right when I pulled mine there was no gasket just sealant.

I've had no issues with the cork gasket but I did apply permatex to it on both sides.

I had problems with finding an exhaust gasket as well, I took my old one to AutoZone I believe and we searched and compared until we found it. Unfortunately I didn't save the information.

This should be the Toyota Part No 1745174051, FEL-PRO 61106, or WALKER 31639 for the exhaust gasket and here's a link https://parts.lakelandtoyota.com/p/T...745174051.html

It may be that my sole purpose in life is simply to serve as a warning to others.

The graphite/mesh wire lower gasket appears to be one of those Rav4.1 parts that is not well documented (or is not documented at all) on U. S. parts sites or at toyodiy.com . The drawings on U. S. parts sites do not even look like what is shown in demoder's video (or service manual?) drawing. I know this is not uncommon.

My googling turns up one candidate for this graphite/mesh wire lower gasket: Toyota part number 9091706073, as shown at https://partsouq.com/en/catalog/toyo...p=1702#7i17451.

A United States parts site says 9091706073 has been replaced by 9008043026 (superceding 9091706024; 9008043026). See https://parts.lakelandtoyota.com/p/_...091706073.html .

Of course I could be way off. I will put this on my list for 'salvage yard research.'

This is another amazing and timely video, demoder. I figure those of us keeping our Rav4.1s running in tip-top condition are likely to need it sooner rather than later.

Thanks, Elle_Rav4 -- I came across those part #'s too, but they are not the right gaskets.

9091706073, 9008043026 -- these are flat, crush-style gaskets used on flange-to-flange connections (no spring bolts), such as the very top of that front exhaust pipe (above the spring bolts, where the intermediate pipe on the Federal emission mates to the exhaust manifold), and also the other end of the long pipe (where the front pipe mates to the pipe that has the catalytic converter).

It's hard to find this gasket because the parts diagrams sometimes don't show the intermediate pipe at all (the short pipe on Federal emissions versions that run from the manifold to the spring bolts connection; that pipe has an opening for an O2 sensor).

Like eodgator said, for now we'd just have to pull it out and take it to a parts store, and see what they have that's the same size. That Walker 31614 gasket might work....I didn't try it but perhaps it would be just fine. It is just frustrating not to be able to find that part number from Toyota, because usually we can pin those p/n's down very quickly!

It turns out that California emission Rav4s also have a different front exhaust pipe altogether, which makes sense because that donut gasket at the spring bolts is a different diameter (2.4" ID on the Cali, 1.94" ID on the Federal). Good 'ole Cali... haha! I think the whole entire exhaust might be different, but I didn't check every part.

Thanks, eodgator -- That's the part # for the California exhaust donut gasket, but not the Federal version. The ID is 2.4" on the Cali, and 1.94" on the Federal.

(Though if anyone has a Cali emissions set-up, I can attest that the Fel-pro 61106 is a well-made gasket, because I used that on my '06 Matrix in place of the Toyota part).

Mystery gasket...

I see two different photos for 9091706073 on the net. For example:
https://www.ebay.co.uk/itm/Genuine-O...-/321817171609
and
https://www.ebay.co.uk/itm/Genuine-T...-/221880769789
The second site above also gives this Toyota part number: 174510J022. Googling for this part number turns up photos of the mesh wire construction. But the locations on the diagrams do not correspond to the Rav4.1's gasket location. Still, it might be the right one.

I think I recall a similar conundrum on one of my old Civics. I am pretty sure I just re-used the old gasket, like you did. Or as Eodgator and you indicate, precision is not that critical for this gasket and an aftermarket close fit will be fine.

1745174051 for California-spec
9091706066 for '95 to '97
9091706065 for '98 to '00.

Could it be possible that Toyota changed / upgraded the gasket's type from mesh-wire to solid metal?

For instance, check here: https://translate.google.gr/translat...l%2F1082127%2F
Someone performs a repair on the exhaust of a Toyota Corona. The old gasket is looking like a wire-mesh type, but the part he ordered to replace it (9091706066) is solid metal.

EDIT: Part number 17451-16030 is listed as applicable on "4rav.ru" (but not on "toyodiy.com"): https://translate.googleusercontent....vSMP1u8zSBdFg#
This member also lists a large number of Toyota exhaust gaskets along with a lot of data (material, inside diameter, outside diameter etc).

Thanks Mick -- that Cali part # is good, but the other two are for the upper-most gasket (flange-to-flange connection). The gasket I'm looking for fits between the intermediate pipe (Federal US emissions), and the front pipe, and it is at a spring-bolt connection. Since there is no flange-to-flange contact at that connection, only the conical-style gaskets fit there, so the flat/disc style gaskets would not work...

But -- you found this one:

17451-16030

Now this one actually looks pretty darn close -- it is the correct "style" (conical, graphite/wire-mesh), and that part # crosses as having been replaced by 17451-0D030, which I cross-referenced on the Fel-pro site, and they cross-reference that as the Fel-pro 61124.

I happen to have that very Felpro 61124 in my parts chest, for a different Toyota, and so I just measured it:

ID: 1.92"
OD: 2.49"
thickness: 0.67"

That is pretty darn close! I think that might just be it. I don't have the old gasket on hand (its re-installed!), but I think that just might be it (Toyota 17451-0D030 or Fel-pro 61124). Thanks!!

Any update on this? I'm so tired of patching these exhaust leaks with auto store gaskets that 'fit' but don't last and burn out due to being just the wrong size. Contemplating just making the jump to a 5SFE manifold and custom adapting a flange style flex pipe and flange connection to the rest of the exhaust...
