GEN 2 Plastic Oil pan #3 leaking. 70k miles. New pan every other oil change. Help?

CGI? computer generated imagery?

Compacted graphite iron. Same material the new diesel engine blocks are built with.

which might be why everyone loves the 2.7 liter motor however the 3 liter diesel (which is no longer offered) is a vastly superior motor having proved itself with Land Rover for years.

I do not get the love for the 2.7 liter motor

I searched and found the c*nt gap index: The size of the gap between a girls thighs when she is standing with her feet together. ie. 1 finger width or 2 finger width etc.

I kind of wonder if it was the block stiffener leaking, so the 2 times they just replaced the plastic pan, they actually weren't fixing the leak....

Nice write up! Thanks for sharing. When you removed the lower pan, did you need to pry it off or did it drop down easily once the bolts were removed? If it came off easily, that means the RTV never adhered to the upper pan, and was most likely the leak source. If the lower pan was adhered to the upper pan, it’s entirely possible that the upper pan was the source of the leak. Did you replace the transmission lines and modify the harness routing per the TSB? If not, I can send you the instructions if you’d like.

80k miles on the truck now, hope to make it to 150k before I buy an electric truck.

The lightning will have a lot more range by then but with the Power Boost out now. It is a beast.

I did not replace transmission lines or modify the harness routing, I saw no need to. What I saw on my truck differed from some directions. I did have to pull the tranny lines out of the way with a ratchet strap to get them installed, but they fit fine after the pan was in. As for the harness, all mounts fit on the new pan, all I had to do was flatten a tab on one ground.

Also, the plastic pan seemed to be stuck quite well and was hard to get off. The block stiffener was VERY hard to get off. I was hoping to spot the location of the leak, but everything was so oily, I really couldn't tell.

The stiffener is for the block, not the pan. Keeps the bottom end of the block and the mains from moving around.

It's a weak block compared to newer stuff. The Cyclone engine family is getting a bit long in the tooth. The block design used in the 3.5L EB engine would never be used in a clean sheet design today. Go look at a 2.7L EB V6 for comparison. That was Ford's 100% clean sheet EB V6 design from 2015. All the highly stressed areas are made from CGI.

Do you need to troll every Gen 2 with your garbage? You’re a know nothing hack, stop spreading misinformation. Gen 2 3.5 isn’t a cyclone, it was a clean sheet design for 2017. There is nothing weak about the design; hence why it’s used in the 640HP GT. The only reason the upper end of the 2.7 is CGI is due to it’s relative output compared to its physical size and usage case. Hence the name “Nano” for that engine family. The 400HP 3.0 Nano is all aluminum, so once again your nonsense is debunked.

I have one of the first Gen 2.7s- it's fine. It doesn't make any weird ticking noises or rattles, and it doesn't leak at all. I don't love it necessarily, but I don't think it's going to be problematic in any way either.

I don't know a damn thing about Land Rover engines and don't care to.
