rain Suck into intake

[YermanCars]

1984 3.2 turbo

Well Disaster Finally Happen I got stuck in some real heavy rain and I don't know what happen but the car started boging out

I thought it was the ignition but it all checks out i think the rain got in the intake because there was like 1/4 cup of water in the intercooler and u could see the water stream when it dried up but it starts but real rough at idle but If u give it gas it bogs and dies I pulled the plugs and cranked it to get any moister out but still the same do I have to pull my heads off or any suggestions

I'd say to let it idle until it dries out completely. Heat and suction should naturally remove the moisture from the intake and combustion system. I think the worst thing would be to let it sit and give the water a chance to start the rust process.

[YermanCars]

How long should it sit at idle because i had it running for about ten min

I don't know squat about turbos, but I seriously doubt you still have any water in the engine, if you did to start with. Pull you distributor cap and see if there is any moisture there. I suspect some part of the ignition is wet.

[YermanCars]

Check the ignition cap rotor coil put dielectric grease on every thing

i know water into the intake on a friend's 4x4 was disasterous. the idiot was forging ahead in flooded streets. water went in, was incompressable in his cylinders and he bent a rod. what a mess.

[YermanCars]

thats what my brother thinks what happen

[jdowty3]

I'd let it idle till it was at full operating temp and you can rev it without bogging. But Kurt is right, you should check the ignition for moisture. I don't think you have to worry about bending a rod in your situation but it's good info for the future. Amazing what a simple thing like water can do.

It sounds like water got into your distributor or other electrical items. Too much water in the intake would not let the engine run at all.

[Venetian]

On a similar note, do you think a Fabspeed type air box cover could allow enough water into the intake to cause a problem? I guess an open K & N could have the same potential problem as well??

If you had it turning while it rained chances are your motor is OK.

If motor was shut down, ingested lot's of water and then restarted (=hydrolocked) then you have bent the rod or did some other serious damage.

Hydrolock happends only if you drive trough the pool and intake (very low placed on 944's for example) inhales water.

There is no way rain could hydrolock your engine while it was turning. Must be ignition or such.

Goran:

If you're driving a 944 through a puddle how does it inhale water if the engine is not turning?

I'm not clear on what you're saying.

I think Yerman believes a large amount of water entered his recently modified intake while driving.

[YermanCars]

rick it did i poured about 1/2 cup of water out of my intercooler

[fredmeister]

The lowest point on the intake system should be the turbo itself so pull the inlet hose to the compressor side and let the water leak out of there and the housing itself. Then pull the plugs and turn the car over, any water in the intake should get blown out thru the plug openings in the heads. Any remaining will get sucked in eventually, and should help make the car run cooler too.

What I'm saying is this:

Only way to bend a rod is to submerge intake into water or pour really big amounts of water into it while engine is turning or try to start it with cylinders hydrolocked. Driving in the rain will not do that. You can actually squirt really obscene amounts of water into engine before it starts cutting out.Chances are, you have really clean piston heads and some wet ignition parts.

Of course, if you actually shut down your engine in the middle of the rain instead of driving it somewhere dry, and then tried to re-start it with one of cylinders filled with water then you would bend a rod as well.

With other words, as long as engine is turning it would inhale the rain w/o any damage (as long as your intake didn't get submerged under water). If you stopped it, let the water accumulate and then tried to re-start it then it's toast.

moisture inside the distributor cap. 3.2s are famous for it.

There is no way your motor could injest so much water in the rain to hydrolock your motor, unless you were driving in a pool of water. Guys with turbos and water injection typically inject quite a bit of water into the intake system when the car is running at high boost, and the engine likes it. Maybe besides a wet ignition system, the water in the bottom of the intercooler blocked the flow of intake air.

I'll second JW's water in the cap.

This is the third time i say it I already check ed and wiped out the cap and put some dielectric grease in it tommarow morning I look at it some more
Thanks guys for all your help

[cyprusx]

Spray some WD40 in the cap and give it a try... WD40 will displace the water/moisture...
