Oil pan removal, do the bolt threads need to be sealed?

Post by **Blacklab467** » 01 Sep 2023, 05:21

As a step 2 in PCV overhaul that I did a couple months ago, I'll be dropping the pan this weekend to clean and reseal and replace the cooler line hoses. I've seen where others have sealed the bolt threads but cannot find anywhere that this is necessary. Can anyone provide some guidance on this, thanks.

Up around the front crank seal, you will see oil coming out of removed oil pan bolt threaded holes. Not sure if there was one, two or three, but I cleaned up the bolts really good and put Teflon pipe dope on the threads.
Be prepared to clean out the PCV block drain channel.

Thanks, thats the main purpose and goal of removing the oil pan, I was suspicious of that return channel and wanted to get it clean, also to replace the cooler hoses.

Not necessary.

Use Permatex 51813, it works better than Volvo or Elring anaerobic sealant.

RMS or transmission seal leak?

Thanks, does anyone have the torque and tightening sequence for the oil pan bolts? I found something on Swedespeed but I don't really trust those guys.
