losing engine power when hitting water

[dar_sbb]

Hey guys

ive noticed that when i do a water crossing of substantial water (yesterday melbourne had really bad floods and issue arose again) the engine starts running of less cylinders. Now this only happens the first time i hit water and after maybe 5mins everything is fine and i can drive through as much water as possible...

So it only happens the first moment i hit water and will last for around 5mins or so... its a bit of an issue cause the truck loses all power and tries to stall and the worst place u want it to stall is in the middle of the drink.

i have a 4in snorkel, sealed airbox and most of the time the truck is sprayed with a water disperser...

has anyone else run into anything like this or can anyone shed any light on the situation

cheers

Come on Daz you should know this...

Water getting into the sparkplug tubes shorting out the spark

simon...??
well i remember when this first came up... u thought it was either that or the injectors not sprayed with wd40 etc...

we had huge rain in melb on friday... and i had recently sprayed everything...

if it was water in the plug tubes... wouldnt it happen everytime i hit water?

 

[samsdad]

Yep..

One thing we both forgot......

Dizzy caps...

Big spray of water up the front of the engine and it's "Miss 'N' F@rt" and carry on and by the way they are mounted on the front of the cams unless you go distributor-less ignition there isn't a lot you can do about it

hmm... thats normally the first thing i spray. All my covers are on aswell.

im taking out bush hopefully in a week or so... will cover everything and let u know how i go.

and always thanks!

Hey guys,

bringing up an old thread.

im giving the truck a bit of tlc, timing belt, valve stem seals, cam seals, water pump and a general clean up.

pulled the caps off and this is what i found:



water has got through behind the rotors from the cam gear and come through to the rotor. This is what i suspect gave me the water crossing issues. I cant explain why it would only happen on the first crossing though. I guess a positive is that it gets out as easy as it gets in.

What i thought where plus points (dizzys up high) hasnt helped the cause. So i wanna know has anyone sealed these a bit better from the back?

I have ploughed some serious water in both my Cressida and Soarer never have i had that issue must be a cover missing somewhere!
