Hi folks just thought you all might be interested to hear that i managed to "superinduct" about 2-3 litres of water into my engine last night. as a result the old girl is not a happy camper and is refusing to do much of anything. anyone with any ideas on where to start drying her out ?

 

Ouch. Presumably it was running, sucked up some water and stopped suddenly? Have you tried to turn it over since? Don't, if you haven't already!

Empty the inlet tract, plugs out, turn it over by hand and see what comes out. Or have you already done that? Guessing you must have done by the 2-3 litres bit...

A compression test is probably the next step.

 

cheers bud. some bellend lost control of his motor coming towards me and i had to ditch into about 2 feet of water to avoid a big smash so it goot a good drink before i could turn the engine off. its not running right but it does start and its got very loud all of a sudden.

 

So what have you investigated so far? Any of the things I suggested above?

Don't run it at all for the moment! At the very least you'll need to change the air filter and the oil. You may find it hasn't actually ingested any water - your running issues might just be water something electrical, or a blocked air filter. If you have though, you're potentially looking at bent valves, broken rings...

 

checked the filters and such and just finished draining water out of the supercharger !! going to carry on through the engine and remove the plugs as you suggested and fingers crossed it will run once its put back together. just sourced another engine "just in case" £300 so not a huge deal thank god.

 

I guess a slight bonus is that with the charger in the way, the water has further to go before it gets into a cylinder and causes a hydraulic lock!

 

yeah I will take any bonus i can get at the moment haha

 

Lee, what about the numpty that caused all this in the first place??

Didn't you get his number, get him to compensate you through his insurance for causing all this?

Keeping my fingers crossed you you mate

 

Ziggy puts things rather well. Intake side, plugs and oil should always be the first things on the list if water ingestion is suspected.

"rather loud"... clattering or noisy exhaust? Your Cats would not have appreciated the sudden dunking, neither would anything belt driven.

Best of luck.

 

While things are apart, give the supercharger drive a spin by hand.

The reason for checking is that the drive has a spur gear arrangement. If the rotors had a lot of resistance to spinning, then the drive might be damaged resulting in the rotors being not in phase with each other. The replacements are not expensive though and can be found on ebay as kits.

 

well after following your suggestions guys i am still dead in the water so to speak. plugged her in and got a list of over 20 fault codes including crank sensor, ecu failure, gearbox failure and underfueling. got a jagtechie looking at it today for a more accurate read. as for the knob who caused it he is currently awaiting the bill for either a fix or a new car. cheers for all your help i will let you know how it turns out.

 

That many codes may just mean low volts to the ECM, perhaps due to water in the electrics.
Sorry to hear of your bad luck, but at least you've got the details of the guy at fault.

 

Even better luck with his insurance. From experience, you caused the damage by choosing to drive too quickly into the flood and avoid the collision.

Whereas you should have allowed the accident to take place.

Unfair I know.

You'll need lots of witnesses to attest to the other guy's bad driving and your necessary avoiding action. Even then....

Hope you can clear the codes when the car is fully dried out, which will take some time and a nice warm heated garage. Lots of blown hot air.

These cars don't like damp electronics.

 

I wouldn't be too worried about all of the codes for now - as above, water + electronics = a bit of a mess!

The big concern IMO is still whether enough water got into the combustion chamber to start causing serious mechanical damage. I'd hope that any garage would look into this before trying to address anything else...

That was my fear too.

 

believe me guys if the guy gets funny about paying up he will be firmly educated in the the error of his ways. i can be a very good teacher when needed

 

Are you expecting it to be coming from him then rather than his insurance company? Sounds a lot more hopeful tbh!

 

yeah he apologised and said to get it done and he would pay for it. i got his insurance details just in case though.

 

ok so the codes from the ecu are changing all the time so it looks like thats damp but i am getting a constant and pending fault on the crank sensor. would that explain the fire from the exhaust and cutting out when the throttle is pressed ?

 

Certainly sounds likely to me. If it's a Jag specialist who's looking at it for you, I'd expect them to know about this sort of thing though. Do they have access to a spare CPS that they can swap in to test? It's a very easy job to swap it, but I'd still be reluctant to start buying parts (even if it's only £60 or so) when there could be terminal damage lurking deeper within...

ETA: an easy (but not necessarily conclusive) test for the CPS is to look at whether the rev counter is reading correctly when turning the engine over before it fires. Again, any Jag specialist worth their salt would know this though!

 

got a spare sensor to try out so fingers crossed this sorts it. really dont want to scrap the old girl but not spending a fortune on a car i didnt pay all that much for to begin with.
