Dipstick / tube / O-ring part numbers

[PDLarson]

I'm not sure if this info has been posted before, I don't have a question so I didn't do a search. I was just doing some research , taking notes and ended up with what was almost a good post, it just needed a little narration.

Unfortunately my V70XC is an around town daily driver. I checked the trip computer and after two tanks of gas, my average speed was 15MPH

I discovered after a couple of recent road trips that my dipstick wiggles loose and allows oil to spray onto the engine. This only happens on the highway but I ended up tying it down so it would not come loose during my last road trip. This definately complicates checking my oil periodically. Now this also raises several red flags about oil consumption (or loss of oil even if not necessarily "consumption") or the PCV system needing service and who knows what else. And all of that is worth checking however, I do notice that the O-rings on the dipstick must have shrunk / hardened because it really takes no effort to remove the dipstick. BTW, if I pull the dipstick when the engine is running, I DO NOT get any smoke or feel any pressure coming out of the top of the tube.

So I decided to replace the dipstick. Here is where the fun with part number substitution begins. I was taking notes, added some commentary and here you go, for the benefit of the community and anyone who may be needing info on the distick and tube assembly, a quick write-up with everything you may need to know. I have not done the replacement yet but I'll try to get some pics.

The original style dipstick 9454823 with a single O-ring is no longer available from Volvo. When replacing the original dipstick (S70 V70 and C70 Models), order Dipstick 9497557. It is upgraded with two O-rings and is only for S/V/C 70 98-00 with updated tube, 9497550. So, you will also need to order the associated tube. On 2001 and newer models, you will NOT need to replace the tube.

For Volvo's built between 1998 - 2000 you will need the following:
9497557 - Volvo Oil Dipstick Red Handle $24.09
9497550 - Volvo Oil Dipstick Tube (C70 S70 V70) $26.44
30637865 - Volvo Oil Dipstick Seal / Tube O-ring (Lower) $2.82
I wanted to use all genuine OEM parts from the same vendor. Prices are from Tasca Parts on 3/8/13.

Or, if you just want to try new O-rings:
955973 - Volvo Oil Dipstick O-Ring $2.01ea, 2 per dipstick (for the new style dipstick, one for the original)
Engine oil dipstick O-ring for any any S/V 70 98-00, C70 98-04, V70 turbo 01-07 all, S60 turbo 01-07 all, S60/V70 non-turbo 01-04, S80 5cyl all, XC90 5cyl all.

If you are ordering the first three parts, you DO NOT need two of the Dipstick O-Rings as they come installed on the new stick. These are only if you are replacing O-rings. However I think these may only be for the newer dipstick so I have no idea if you can just swap out the O-ring on an older dipstick with one of these or not.

Here is all the info on part numbers, new and old:

Dipstick 9497557 replaces 9454823
Dipstick tube AKA "pipe" 9497550 replaces 9207964
Dipstick Seal 30637865 (for the bottom end of the tube)
-OR-
Engine Dipstick O-Ring 955973

This has been discussed here before, so the answer to the issue is that: one does NOT have to change the dipstick housing.

I thought that I had no choice but to update my dipstick housing.....until I did my research.

If you go to Volvo dealer and ask, they will say 1271921 is no longer available, you have to buy the new dipstick and new housing! It is simply not true!

So I took my chance and ordered 1271920, guess what, the label says 1271920 but the dipstick clearly has 1271921 engraved on it!

So technically speaking the PN is identical to my cracked old dipstick.
Volvo somehow sneaks it in (using 1271921 for 1271920).

However, there is a very very slight difference in length, if you look at the Min. mark, it is about 5 mm in length difference.

In the big scheme of things, it makes no difference anyway. Just order 1271920 and you will be fine. Just keep oil level near the Max mark.

Good post but cn90 already figured this one out, see above.

Also, something's not right here, or I misunderstand, on the o-rings and seal:

-OR-
Engine Dipstick O-Ring 955973, order 2 per dipstick (the P/N is for one O-ring)

The little O-rings are a completely different size and part than the sealing ring. So ordering two of 955973 and none of 30637865, is not a solution. Not sure what you are trying to say. Unless you want a spare o-ring (good idea!), there is no reason to order two of 955973.

The newer dipstick has two O-rings and as I said, I know the replacement O-rings are the ones meant for the newer dipstick which has two. I was simply thinking of the newer stick when I wrote that about ordering two. I am pretty sure these fit the original stick, in which case of course only one is needed. I just didn't want to say that without knowing for sure.

But yes, I should have said, order two if replacing O-rings on a newer style dipstick or only one if you want to try just replacing the single O-ring on the original style dipstick. Of course having two and needing one at these prices is not too big of a deal, especially if one is lost or damaged during the install.

And about the O-rings and seal, the seal is one of three parts needed if replacing the dipstick with a newer one and the newer tube. The seal goes down at the bottom end of the new tube. With these three parts, stick, tube and seal, O-rings are not needed. If just trying to replace the O-ring(s), no seal or tube or new stick is needed.

CN90, my V70 calls for 9454823 which was replaced by 9497557 which has two O-rings rather than the single O-ring design of the original, the 1271920 or 1271921. The 1271920 idea is a great option. I was not aware of that. In my case, (before I even posted) I had concerns about the marks being different if I tried going with another stick and also about the stick blowing out of the tube so given that I thought the new design looked better with the extra O-ring, I had already deided to order the three pieces to replace the whole assembly. Not really a difficult decision for me after having to deal with an oil-soaked engine bay once and a stick that pops out every time I get on the highway or has to be tied down. I'll spend a little to insure I don't have to worry about that anymore.

Thanks for the replies. I'll try to post back with any more pics or info after I do the job.

The newer dipstick has two O-rings ...

Aha, I get it! Thanks for clarifying, I can see my post about no need for two o-rings, was wrong.

[PDLarson]

No biggie, I should have posted pics or explained that better. I was running late leaving work and had people waiting on me plus I knew I'd be posting pics later. For the benefit of others who may stumble upon it, I'll edit the original post to fix that.

- If oil is coming out of dipstick, the 1st thing to check is the PCV system. The stock dipstick (single O-ring) lasted some 14 years for me.
- Despite the fact that Volvo says use this part, that part for this year that year, virtually all 5-cylinder during that period uses the same dipstick:

PN 1271920 will be fine and cheap ($16 at dealer).

Yes, you're right / I know

Now this also raises several red flags about oil consumption (or loss of oil even if not necessarily "consumption") or the PCV system needing service and who knows what else. And all of that is worth checking however, I do notice that the O-ring on the dipstick must have shrunk / hardened because it really takes no effort to remove the dipstick. BTW, if I pull the dipstick when the engine is running, I DO NOT get any smoke or feel any pressure coming out of the top of the tube.

I will probably be doing PCV and timing belt this summer. With the Montana weather the last several months and lack of a heated garage, It's tough to get stuff like that done this time of year. I'm all about saving money but in this case, I chose to go with what looked like a stick that will hold butter until I get that done. I guess i figure it was redesigned for a reason. Also, it's worth the little extra cost to me for the peace of mind that I won't have to check it every few miles on a road trip or keep it tied up, leaving me not checking my oil as often.

So I guess we've come up with two options and I'm sure you're right, the stick you referenced I'm sure would work fine.

According to many posts about this over at at Volvospeed, the new dipstick tube is supposedly much better at not splattering oil.

[cn90]

The factory dipstick never splattered oil in my 14 years of ownership.
