3.8l engine has been used for a long time. Only issues I’ve heard of is main bearings spinning. But you hear that with every engine. Because $$$$ lol. I have the 3.8 with about 115,000. Change the oil every 4k and use Castrol edge 5w30, only work I’ve done is resealed the oil pan. I need to do the intake gasket also but other then that. Great engine. Plenty powerful (with the right gearing) and reliable

How much water did you go through before it got fucked up ? I’m a new Jeep owner, Am i safe if I keep it below the floor boards ?

0
John

About 12″ but hit some soft mud and had to floor it .. when I did it pushed the water just right up to the intake …go slow and if you start sinking don’t floor it . Lol.. just put a snorkel on and save yourself the headache and lots of $$$$

@John What mods were on your jeep at the time? I have a hard time picturing this happening to a stock jeep.

0
John

Just some 35″ tires .. but look at your stock air intake ..the opening is right up in the front passenger corner and so going in head first at a slight decline then punching it …all the water rushed up to that corner…
Honestly it didn’t take much water to bend the rod

John

Correction …i did have the 4″ BDS long arm lift and stabilizer at the time too

Kenneth

I just didn’t know if you had modded the intake and/or inner fenders. You must of really hit those puddles.

How much of a pain was that snorkel to install?

0
John

It had the stock outer and inner fenders at the time and stock intake ..
Yeah it didn’t take much to make the water rush up there

John

It wasn’t too tough… getting the piece in behind the shock was the biggest pain
