I heard the driver was on the fire and rescue team trying to get to a hurt snowmobiler on the north side of the pressure ridge.

if thats the case Roebag, it just became apparent they need to implement some ice rescue training, about grade 2 par type stuff!! I thought pressure heaves were self explanatory.

keep a strain on er.

Default Open Lead after a Heave

I was out yesterday, and I am guessing that is north of Brownlow's. We saw lots of "wet white ice" in the vicinity of the pressure ridge. Given the minimal thickness in the photo, I hate to say I suspected open leads from the shifting sheets of ice. If this was flood ice that refreezes, you would see a deep blue color, as opposed to the whitish colour you see here in the picture. The pressure ridge itself had 3 foot thick ice piled about 8 feet tall right at the point north of Brownlow's, and it was very blue ice, except on either side where the sheet had broke free from the horizontal ice, after reaching considerable height.

Glad to see no one was hurt. If the motor was still running when the airbox submerged, the block is toast from the compression of the "watered" cylinder on the upstroke.

The engine will be fine, take out the spark plugs and crank it over till its dry.
Dry the Dizzy.

Water doesn't compress.

Most insurance policies will not cover a vehicle if it goes through the ice,unless it is on a winter road approved by the department of transport.At least that is what my policy states.To top it off,if the vehicle goes through the ice,the owner is given a period of time to remove it,or the province will remove at the owners expense.

expect bent rods, broken pistons and a possible cracked block

water doesnt compress.....thats why parts break when water is taken into the chamber...saw a HEMI last year that took on water trying to launch a sea-doo....it was not pretty

That is scary!

To anyone getting on at Brownlows. Head right as soon as you are on the ice. You should find a worn track and nice passage over the heave that is practically at shore. I felt very safe crossing at this spot. The rest of the heave seems to be slowly rising as the ice expands and contracts.

No way a block is going to crack from getting water in the combustion chamber. That's such an exaggeration... the Head Gasket would blow under that pressure long before a cast iron block would crack. More likely it would just stall.

I don't either and I always roll on the lake with the window down a crack.

never say never...it could happen and they will be looking for that when the machinist tears it down.....

but your probably right...on a stock motor if the head gasket holds you may just lose a rod like that HEMI i saw first hand....rod bent and piston went kaboom...was pretty cool LOL

I could totally see the rod going if the HG did hold, just like breaking a timing chain!

for sure the engine is done if water got into the cylinders before it stalled. i have worked in machineshops for 10 years and you would not belive what a really bad blowen head gasket will do to an engine. i remember one volkswagon that had one rod out the side of the block and the other wraped around the crank

I sank my chevy at a river crossing once and sucked my new 350 full of water.Pulled the oil drain plug to drain the crankcase(about 2 L of water came out before the oil started to come WOW),put new oil in,pulled the plugs to drain the cylinders,turned it over for a few seconds.Then we left it overnight.Next morning it still would'nt start because the mufflers were full of water and there was too much back pressure.A screwdriver and a hammer fixed those.A half cup of gas right down the carb and she sparked right up.Another oil change once we got home and it was like it never happened.That was about 15 years ago and I still have the truck.
Another guy i know had his truck roll into a lake backwards at a boatlaunch with the engine running(the roof was about 4 feet underwater)It took about a week and it was back on the road.Although he could never get the lake smell out of the cab.
The potential for damage is there,but in these instances there was no permanent damage.But a guy cannot wait to do something to fix it because raw cast iron such as the internal parts of an engine and the block itself will start to rust immidiately and then you may have problems.

This is what I would expect.

I think you would have to have some really high RPM and a large quantity of water to make an impact strong enough to break a rod.

The only way the block will crack rather then the gaskets take the force in my opinion is if the cold water cools the block faster then the iron can contract. I seen a guy try to wash his wheeler in the lake and do this.

I think (Not a mechanic) I would try replacing the air filter, and fluids, drying out the electrical in a heated garage and replacing the distributer cap/ignition box.

Default Lynnwood Neighbourhood July 11, 2004

Anyone in Edmonton will know that Lynnwood / Rio Terrace had flooded streets on July 11, 2004. Countless people tried to drive their vehicles through door deep water, only to blow apart their engines when the water got into the engine from the air box. There were right offs like crazy as alot of cars and trucks were not worth the cost of replacing an engine at new cost.

Water does not compress. Heads do crack. Piston rods blow under pressure.

Anyway, good luck to the fellow, and I hope I am wrong. Maybe he shorted out the engine control module before it drew water, and he is OK.
