2005 Lincoln LS V8 Ultimate

2005 Lincoln LS V8 Ultimate
Was told head gaskets were bad, seeing quite a bit of coolant in the crankcase I didn't disagree. But after countless hours of reading and researching and learning that it is VERY uncommon for head gaskets to go in these cars I started tinkering. I drained close to 3 gallons of milk from the crank case filled it back up with some oil and started her up.she took as much water as I could get into her, every bit of water I threw at her went straight into the crankcase. I am positive the head gaskets are fine but my question is I am unfamiliar with the ford engines so what gasket is bad that's causing the coolant to go directly from the fill port on the front of the intake into the crankcase? I want to get an idea before I tear it apart so I know somewhat to expect.

Well, head gasket / head / block failure is very rare, but not impossible. It's rare mostly because of the failsafe cooling, but if the previous owner (or you) ignored cooling system problems for long enough, it could have caused this. There are only four failures that I can think of that mix oil with water.

1. The oil to water cooler (the oil filter screws on to it). This happens and is not too bad, however, this seems to always cause oil to go into the water, not water into the oil.
2. Head gasket failure. A leak down test should find this.
3. Warped or cracked head. A leak down test should find this.
4. Cracked block. A leak down test should find this.

All of this is academic. You have water in the crankcase. The bearings are done, and replacements are nearly impossible to find. That engine is done.

Air box was full of water, water in intake also. After I filed it back up and it seemed to never stop I redrsined the oil to find every stitch of water I poured in was in there. I bought the car like this, new degas bottle and remnants of bars stop leak around the filler spout
Thinking about pulling the intake manifold off so I can see a little more of what may be going on. I have an 03 sport but she has high miles so I don't really want to go through the hassle of swapping an engine for one with double the mileage. But I can't be entirely sure how long thus engine had been abused and ran with the milky goooooo

Well, that's more information.
It was hydrolocked. The block is probably cracked on the inside. Probably bent some rods too. No hope at all...

Car runs right now, could keep coolant system empty with fresh oil and she will drive other than plugs being shot from coolant. No knock just a miss.if coolant stats out of the oil she will run all day

 

[Oldsman003]

Drove herself onto and of the dolly and around the yard, like I said I could change the oil and empty the coolant system and she will run quietly until she gets too hot to run, I haven't over heated it but not saying it hasn't been before I got it, like I aid coolant runs into the crank case as fast as I pour it into the fill spout

 

[Oldsman003]

Im grasping onto the hope the bottom end is salvageable but I feel I need to pull the top end apart to see what is exactly going on because the size leak there is should be extremely apparent once I can see inside

I'm not a newbie backyard mechanic, I buy fix and sell used cars, usually engines and transmissions. Not every anything small. But this car I purchased for myself I actually bought 2 others for parts and sell at the sane time. I own a 2000 v6, 2003 sport v8 and this 2005 ultimate v8, the 2000 is strictly a parts car for body panels, the 03 I was going to resell to help pay for the 05, but if my ultimate need an engine there is my doner

 

[joegr]

Odd.
I think that just having had water in the crankcase means that the bearing will be gone in a month or less.
Whatever has happened must be major if it pours right into the engine. You can pull the intake manifold (fairly easy to do) and see if you see anything looking down at the intake valves (probably won't). There are no coolant passages in the intake manifold. You can remove the water outlet pipe, crossover, and water pump. Maybe you'll see something through one of those ports. Lower oil pan is easy to remove too, but you may not be able to see much. You could also bypass the oil-to-water cooler to remove it as a suspect. (Just clamp down on the two water hoses going to it.)

Still, I don't see there being any practical repair for the internal failure.

Here's my 03

I wish I knew more about the modular engines because I've been more g.m. I'll just have to get in there and see what's happening.

The 3.9 is not a Ford modular motor. It is actually a Jaguar AJ engine.

Just curious, but could this be caused by the throttle body heater hoses being connected to vacuum ports on the intake? Found this older post where Joe suggested this could be the problem, but that was for a 2000 V-6, so I'm not sure if the same problem would apply to your vehicle. Here is the link to that thread. http://www.lincolnvscadillac.com/forum/showthread.php?98225-00-ls-v6-coolant-issue&highlight=coolant+in+oil
Hopefully this is somewhat relevant. If I am way off, I apologize. Best of luck

Jaguar....damn sure looks like a modular to me they must be extremely similar
Oh well
The 2000 I have is a v6 and from just looking at it are completely different I guess being from what was said one is ford and the other is jaguar.

I have it dripping dry as we speak and I'm going to let the crankcase soak with some kerosene while I pull the top end apart to see what's going on. Maybe I can find something out

well they are both 4 valve, twin cam motors (well some of the mod motors anyways) so they would look very similar on the outside, especially with how different they are from GM's push rod motors...

 

[Oldsman003]

If for some reason this thing needs an engine, what am I looking at process wise in an engine swap? It looks straight forward I am actually impressed with the amount of room is around the motor. It's just I haven't worked on one of these before and this is my first and last LS purchased to be my personal vehicle, my Oldsmobile 88 that I've had for a decade has just topped 350k, so she is on borrowed time so this is her replacement. Just trying to get my ducks in a row before she gets torn apart and becomes a "dead" vehicle for the time being

Main bearings are actually easy to come by. But you WILL have to go through the internet and buy them from a source in England. Each half-shell is about $5-6 and you'll need to mix-'n'-match them to get the proper clearance so do your homework first.
