She's on her last leg

[AeroNautical]

Months ago I did something stupid and hydrolocked my engine. Rymanrph was there to record it all, he could tell the story better than I could. I knew once we got it running again on the trail that I was on borrowed time with the ol 4.0. Well, the time has come. I'm burning a quart of oil every few hundred miles, don't need to do a compression test to know the cylinder walls are scored to hell from the muddy water that filled em. 

 

I'm on the look out for a functional, preferably Renix 4.0. Junkyard would be a last resort, because I know many of you probably have a couple collecting dust. I'm posting this in the Pub because I'm not quite ready to jump on a purchase yet, but I suppose it's more to share your stories about required engine swaps. And to tell me the MJ "ain't a gosh dang submarine".

The air inlet on the XJ/MJ is poorly located. You are far from the first to hydrolock one.

I don't have a 4.0 but I do have a 4.2 collecting dust, trying to decide if I want to use it for stroker parts or get new parts and get rid of the motor

Yeah, i'd heard the air box placement was bad, it's one of the first things in the engine bay to submerge. Is the 4.2 the same as a 4.0, just a larger displacement?

The 4.2 is what came before the 4.0 and is carbed in stock form. Its crankshaft is the starting point for a stroker.

Crankshaft and rods.

Too bad you're so far away.

if I understand what I have read, all I have to do is replace crank and rods. no other mods needed correct?

[cruiser54]

Kinda sorta. search "junkyard stroker"

Sorry to hear that. Back this summer I did the same thing with my 4 banger. I flushed it out only to have it throw a rod about 1000 miles later. Once you submerge them they really are never the same. Just completed my engine swap with another 4 banger back in Oct. its running well again. I hope you find something that works well for you!

Yep, just did her final oil change with a heavy additive that's supposed to improve compression by rehydrating the piston rings or something. Hopefully I'll burn a little less oil with it until I get my next powerplant.
