new owner with some questions...

Rebuilding the other oil cooler lines solved the drips of oil I saw from under the front right side of the car, but now there's oil coming down under where the RMS is located. If it's not one leak it's another

The oil lines need to meet a temperature rating. I would stay above 270°.

I can't imagine a hydraulic shop not doing those lines when they do HIGH pressure stuff for trucks and other equipment all the time.

Hopefully the other leak is the rear cam seal.

Yeah I was sorely disappointed, didn't make great sense to me but they were firm. The part they didn't like was cutting off and re-using the fittings without the big factory crimp, even if I cut them and brought them in. But likely many other (most?) shops would still do it

I have an update on the oil situation but first, Robert, your dedication to Volvo repair and your many detailed instructional videos are absolutely wonderful! Thank you

Now on to the oil leaks (yes, plural). Last night I put the car up on the lift and did a thorough inspection of the leak area. I took before photos, cleaned it off very well, looked again, ran the car in drive on the lift for about 15 minutes and kept checking. I took after photos as well. From what I can see, there is oil coming from the drive axle seal (maybe above it, too), the weephole around the RMS, and the bottom front side of the transmission pan.

Thanks.

What is that loose blue vacuum line in the first pic?

[erikv11]

Transmission pan and drive axle seal shouldn't leak oil, only ATF which is pink. I suspect those are somehow related to the other leak(s).

RMS weep hole looks pretty conclusive.

The all leak at the turbo, wouldn't worry too much about that unless it is copious (apologies but I didn't read earlier in your thread if you already talked about how much it is leaking).

Good eye! I was running a new silicone vacuum line to replace the rubber one and took this photo half way through the process.

I was afraid of that. I'm thinking now that the oil around the drive axle seal is leaking down from above, probably from where the oil near the turbo is.

And just yesterday I noticed a new oil leak near the distributor cap (see photos).

All these small leaks would be very unusual for these engines, things may not be as bad as you think. This is the first leak up high on the front, if you can figure it out then check the RMS and trans locations again. Have the rear cam seals ever been changed? Pull the cap check for oil underneath.

The previous owner said he replaced at least one of the rear cam seals right before I bought the car. I had noticed the oil leak under the car when I test drove it and pointed it out to the seller. After he saw it, he said he would see about fixing it and replaced at least one cam seal.

Rear camseal leaks will make a HUGE mess all the way to the bottom. Ask me how I know. They are easily to replace, so not sure why PO didn't do both. I'd check them first, then remove all oil on engine block before thinking it's something far worse...and expensive.
