Like an idiot, I thought this beast could make it from Dallas to Austin in pretty hard core rain. After about 25 minutes, it became too stressful and I pulled off the highway into a covered gas station.

After waiting out the storm, I turn my car on and notice the exhaust is a little throatier. I notice when in park things are vibrating a tad more. Nice.

Then I put it in gear, and it drives forward, but jolting back somewhat forward and backward, while maintaining forward motion in the wheels.

.. is this water in the engine? Can/should I wait for it to evaporate? Kind of in the middle of nowhere, called the nearest highest rates mechanic, he said he doesn’t have anyone who can make it out over here but I could drive it there.

EDIT: Also should note, when I pulled up to the gas station I felt nothing wrong. Only after starting the car 1.5 hours later when the rain stopped did I notice it.

 

I got blessed when someone who builds race cars pulled up to me with my hood up.

We were taking a look at the sounds, I told him about the supercharger coupler issue I have.

He had me take it up to low revs, said there might be some condensation on the spark plugs (or fuel injectors?) and to let it run idle to air out. Then I should be good (going to take it to an Indy when I get to Austin).

I’ve attached a video of the engine

 

Exhaust note, seems to be more rhythmically up/down than usual

 

Providing an update, have barely moved

Went around the corner, engine light starts blinking, power doesn’t feel right.

Going to get it towed

 

Ouch... I was just watching the news about Dallas (I'm from Houston). I hope nothing too serious is wrong with your beast.
I also have the issue with my supercharger coupler, although not as pronounced as yours in the video.
Goodluck and keep us updated.

 

While water would certainly seem like a cause, letting a car sit with a warm engine compartment should certainly vaporize any water after 90 minutes. If you can get it to any shop that has a scanner, see what the ECU is unhappy about. That up and down idle sounds like it can't find the right mixture... or something.

 

Sent it to Autobahn Jaguar. Had to Autobahn Jaguar Fort Worth

If they find that the issue is due to weather/water and if it's expensive enough to bother, you might consider an insurance claim instead of just paying out of pocket.

 

What was the resolution?

 

cylinder compression test coming in low, they thing it’s bent rods. Working on insurance now.. considering putting a Ferrari engine on it if I can get a total check

 

If that's true, you apparently drove through some really deep water, deep enough that the engine "inhaled it", and since water isn't compressible, something had to give. Thing is, that should have been extremely apparent immediately after it happened, not "sometime later." Honestly, I'd get a second opinion. Yes, compression may be low, but if you're giving us the full story, it being the result of water intrusion still sounds highly unlikely.

As for swapping in a Ferrari engine, it's your car and your decision. That said, it'll cost a lot, cost a fortune to maintain, and may even drive down its resale value, if you care. It's not just the engine, but everything else that'll cost more than expected: transmission and/or adaptor, ECU, transmission ECU?, wiring, fuel system, exhaust, etc, etc.

 

hm. I’ll see what the insurance company says, already filed the claim.

 

no water got in, so it never got up to the bottom of the door.

I was driving on the high way though, and the intakes are pointed down. Maybe I hit a puddle and some got pushed up?

 

Consider me subscribed for the Ferrari swap - I think it’s a great idea and I support it 100%.

 

The stock intake snorkels are not pointed down they are pointed out to the front of the grill, ie horizontal with the ground. Just guessing from memory but the intake mouths sit either just below or just above the level of the grill cross bar so a fair way off the ground. Have you fitted after-market lower intakes such as the Mina Gallery set up, because those intake cones do point down? Either way it is possible for a deep puddle to splash water up into the intakes, especially if taken at speed.

 

don’t believe I have after market intakes. I bought it used but would think the jag mechanic would have brought it up

 

I remember another YouTuber a few years ago who killed the engine in his C63 AMG after going through some big puddles - water got sucked in through the intakes and hydrolocked it. Not sure how it gets past the air filter(s) but there you go....

Maybe WatchJRGo would like a sister car to work on for his ongoing series ;-)

 

Just FYI...If it was not related to water/weather, it won't be covered by insurance.

bruh lol

 

You do realize that is the image for the non-stock Mina intake?

Oz's comment is about the "stock" intake...
