2001 V70 T5 Sump questions and refit advice

siboyslim · Post by **siboyslim** » 02 Mar 2015, 09:02

Hello all!

I removed the sump from my 2001 T5 over the weekend and want to show you all the pictures for your opinions

The thing was covered in black sealant inside & out and the pick up pipe was full of little black bits (which I assumed were bits of sealant????).

Now it's all off and cleaned how in the world do you guys get them back on with out upsetting the sealant?

I cant even get the sump back on in one let alone with the sealant on, I must be missing something.

Thanks All

Si

Is that the PCV port at the bottom of the 5th picture?

Yes It looks like it!

The sump port is clear but the one in the block definitely looks blocked, is it safe to poke something up there?

Well spotted

The one in the block goes to the PCV box, you can try pass a stick or something to clear it, but most probably the PCV box is also clogged, by the looks of the port. But it's good to have the sump removed, because the sump port cannot be cleared otherwise (and must be done when the PCV is replaced)

While the pan is off, you can try checking the rod bearings for play by hand, especially the one on the 5th cylinder (this one happens to get some wear if the oil pressure was too low because of a clogged pick up pipe mesh)

Next step, pcv replacement, another couple of hours of fun

As for the original question, I don't know tips, but maybe this video may give some answers, it shows somehow a similar looking situation with an engine in need of a good cleaning

This port also looks a bit clogged, could be the one that goes to the cooler?

Thanks for the info, been dreading PCV replacement but it looks like it will be on the cards very soon, hope it gets warmer soon! Way too cold for this sort of thing.

Don't worry about the oil cooler I plugged the hole with a bit of rag:) looks just like sludge.

I see many miles and years of oil sludge - those little bits are crusty oil. My BMW looked the same, my S80 was not so bad. Clean it all up - really clean. Take out all the parts and work around the baffles. make sure your pick up tube and screen is clean.

Looks like your sump pan has been played with before. That does not appear to be factory sealant - they use Anaerobic Sealant not RTV.

To install pan you have to practice, practice and practice with your clean pan so you can get it in without bumping anything. You have to figure out the twist, tilt, turn ... so it goes in. Once you got it down you are ready. Make sure you use the right sealant, roller it on thin, make sure all your O rings are in place and go for it. Helps to have a second person to hold the pan on while you tighten the first bolts. Follow the pattern. One more thing - replace ALL of the O-rings as these wear and leak with age. I use brake cleaner just before I install on the sides to get those final little drips, then wipe clean and move quickly to avoid more drips.

I recently dropped the sump on my '05 2.4i V70 with 266k miles. Mine was in much better shape, probably due to the dealer oil changes every 7500 miles:

My advice is similar, practice to make sure you know how to get the sump back up in a quick and safe manner. Definitely have a helper who doesn't mind getting some oil in the eye, so that one person can hold the sump, and another tighten the 30 bolts. I used vaseline to hold the o-rings in place, and used the volvo gasket maker in a tube ($$) with a cheap paint roller to spread it out. It was a bit of a pain to redo all the bolts (per the volvo instructions I started with one at each corner to get the sump attached), but not too hard once the main issue of safely getting the sump back up was achieved.

Wow thanks for the pictures!

I managed to get it all back together with the help of a spare jack, otherwise like you say it would have been next to impossible.

Looks like mine has had an illustrious past then

I will be dropping the oil again shortly as we are coming up to 2000 miles since I dropped the sump, then extend the changes to the 7000k mark.

Thanks

Yes I would really like to know the past of the car, I bought the car only a few months ago.

Strange thing is there are tons of bills & receipts for service work and oil changes.

Anyway the sump is all back together with fresh O-rings and it is running better than ever, to be fair it was a tricky job getting everything clean and dry.
