Concerned Owner of 50k miles 2020ST. Need help!

[Cruising68]

Does anyone know if Liqui Moly 5W30 full synthetic oil is good for our ST? I live in Canada and winters get very cold.
Summers are very hot.
Many people are telling me toswitch and use this motor oil. Any thoughts?
Tks.

Liqui Moly is generally good stuff imo. I would think with colder temps you would be better off with a 0w30.

I have oil leaking as well. It's leaking from somewhere. Took it to my mechanic and they cleaned and washed all the bottom covers which were completely saturated in oil. They cleaned the engine bay as well but couldn't find the leak. Drove it around for a few days and took it back today. It's leaking again badly. They think it's pressure building in the crankcase that blew out and even caused the oil pan to crack and needs to be replaced.
They have to take apart everything to figure out the leak. Guy said it could be coming from the diff as well.
They want to test the pressure in the crankcase first to see of its good or not.
Looking at around 1k to fix.
Any ideas?
He asked about the mods I've done concerned about the pvc/intake.
I have the stock intake but did put on an oil catch can.

I have a few mods as well:
JLT oil catch can
SPD 3" catted DP's
Turbo smart BOV
Whipple IC
93 tune by JDM
Borla Atak catback with custom mid dual xpipe

I'm not an expert so I'm hoping someone can lend a hand with the details I provided and maybe shed some light.
Sorry I don't have any photos atm.
Tks.

I believe that I saw a ST video on YouTube that noted that there was a Ford technical bulletin for 2020-2021 for 3.0 and 2.7 Eco-Bust turbo V-6s. Ford replacing lower seals with new adhesive method that has been used on the 2022-2023 Explorer ST.

There is an emissions warentee. Look it up. But federal law mandates the emissions system to be under watforblike 10 years 150k miles or something. You have to fight with them, but look up the law and then threaten legal action after you show it to them. They will then cave. A reputable dealer should just replace it under that warranty to begin with.

Here is the law. This is federal mandate, so any emissions item must be replaced if bad for 80k miles or 8 years. I see this is an old post, not sure why it was in my email with new activity, yet last post was in Nov. Lol. But I was a little high in my thinking but at 3/4 years old and 50k miles, Ford is forced to replace it. If they don't, file an EPA report and you will have Ford reaching out to schedule the replacement ASAP.

THERE'S A THING CALLED PART NUMBERS. IF YOU INSERT THE PART NUMBER AND ADD IT IN OASIS AND IT SAYS NOT COVERED HOW IS IT COVERED?
