2001-2007 XC70 oil pan drop question

[XC70Rider]

I've used mini rollers to evenly flatten out this sealant on other oil pans and only a small percent stuck to the foam. I think your concern is the cloth type covers that fit onto these rollers when painting.

If heading to HF get this roller and you'll be fine:

I read all 10 pages of the link you provided and got more tips on getting the PS lines and engine mounts out of the way to drop the pan. That link also gave tips on replacing the gear oils. I already have 3 liters of Valvoline 75W90 GL5 oil along with 18x24x1.5mm crush washers so I'll be replacing the fluid in the bevel and final gears also.

Is there a matching paint roller at harbor freight tools? I'm concerned about the sealant sticking to roller. Pix for reference? like this:

I bought my foam roller at the Dollar Store and keep it in the nice little package it came with. The sealant will stick to the roller but it will not harden and you can reuse it as is if you store it properly.

The NAPA sealant I bought was somewhere around $15-20 for 50ml.

Not even abscate re-uses foam rollers. Posted in Scott-free font so that he doesn't start picking my garbage can.

abscate next you will tell us you don't even do your own work. Just send it to the dealer??

Nothing wrong with reusing the roller - the sealant doesn't dry. I, and many others, just apply new sealant and then reuse the roller as it absorbs a slight amount. The roller's purpose is just to smooth and level.

Personally I have never had an issue with this method, but if one is unsure it is their money.

How badly do you treat your cars if you need to take the engine apart so often you haven't moved and lost the roller in-between?

I have never touched an anaerobic repair on a Volvo. I have just done several. I have on an Audi where an unrelated issue developed. Never a leak - anaerobic sealant is good stuff. The secret is preparation - basically apply to a extremely clean surface and lay down a consistent thin film.

My Dollar Store roller and its mini tray and plastic container is always stored in the bottom drawer of the tall red rolling tool box. Its longevity has become a sport. It is one of the few items I can always find.

I know the bolts for these pans are M7 but does anyone know the thread size? Are they M7x1.5mm? Reason asking is I when I reinstall the pan I'll temporarily put some studs on the block for alignment.

Pick up few M7 x 1.0 also.

I'm feeling strong to DIY after cleaning the outside and around the pan -- counted all the bolts! Now it smells good and desirable for a DIY but not as sparkling as my kitchen sink. The long handle and round parts cleaning brush for $2 from Menard's is best for this kind of job. Simple Clean concentrated gets thumbs up too -- zero fumes.

2001-2002 V70XC are similar.
Is the motor mount near the belt coming OFF to clear the pan?
1-2 bolts near there are NOT a straight shot, IS IT?
Would the turn of EVAP line traveling along the subframe cause a problem?

When I did my XC70 pan many moons ago I followed the advice to master the install via "dry fitting". I also tried using studs, but I found it didn't work well. What I settled on, after "dry fitting" mastery was to have a helper (or a jack would work but dry fit), hold the pan as I installed some longer alignment bolts on or near the four corners. I did not let the pan contact the engine. From there I pushed the pan all the way up and started installing the rest of the bolts finger tights. Next torque to spec in appropriate order.

On a S80 I was just brave and after a dry fit, final clean inspection, placed the pan and used a jack with a wood block to hold it after I got two corner bolts in. Just have your extension on if you are using a short socket and the bolts accessible. Pick initial bolt placements that will keep it aligned and not have interference when installing.

Overall worry about the difficult bolts after the pan is aligned and on, but final torque correctly (as possible).

Care that the O-rings stay in place is a MUST! Care that any excess oil does not drip down while sorting all alignment issues is a MUST!
