10w40 would be more appropriate for these n/a high mileage cars...5w40 too.

5 or 10w30 is too thin...it should only be used in extreme cold climate.

But...again...it's your car and you decide what viscosity oil you will use in your car.

You could also clean it up and add uv dye to just the power steering reservoir , then see if it glows! https://www.amazon.com/ACDelco-10-5045-Multi-Purpose-Fluorescent-Detection/dp/B008I2VPC4/ref=sr_1_2?crid=3DLR5GL2MROIE&keywords=Uv+tracing+dye+oil&qid=1651218474&sprefix=uv+tracing+dye+...

I only know a bit on this one, as I have only owned autotragics. a) Definitely. Turbos have a larger outer CV. Fit is completely interchangeable however. b) Yes, but also interchangeable. c) I think not. See this thread, tryingbe was very knowledgable on 850 manual swaps: https://www.matthewsvolvosi...

When performing preventive maintenance like a timing belt you know is overdue for replacement but is showing no signs of any problem, what do you do with all of the perfectly good parts you remove from the car?

Against better advice here, I did not do the oil pan rings (since they would be as much work later), The motor runs about a...

Which aftermarket parts brands do we trust and which should be avoided? Which brands make the parts that Volvo sells under their brand and is there any difference between theirs and Volvo? Which parts are better bought as Volvo brand instead of any aftermarket? Please reply with any: - Information a...

I can't speak as to the M56, but I pulled Sveedy's engine out from the top while leaving the auto trans in place. Had no problems with it.
