So I noticed every time it rains my engine is a little wet and only where the injectors are. So my injectors fouled out 3 months ago. When I pulled them out I got a suction vac, inserted it in all 8 holes and took out about 1.5 gallons of water. How do I stop this from happening again and fouling out my new injectors??

 

The 1.5 gallons of water was INSIDE the intake manifold, and pulled out through the injector bosses? And this is a stock LT1engine?

 

Also need to provide basic info about the car - year and model, in particular

 

Sorry for being a noon but yeah through the injector bosses I got the water out. And it is a 94, trans am LT1 nothing is stock on it. Headers, cam, cold air intake, 3.5 exhaust all around, new suspension

 

Does this car have a hood?

 

Yes it has a hood..

 

Do you have a aftermarket "cold air intake" where the air filter is mounted down low around the bumper area?

you sucked 1.5 "gallons" of water out of the intake through the FI holes??

is there water in oil? (does oil look "milky")

 

Then I am at a loss as to how the top of your engine is getting wet when it rains. Such a bizarre thing. Is this when sitting still or driving?

 

Water entering the injector bosses would flow by gravity all the way to the intake valve. If the valve was open, and few will always be open at any given time, based on cam position, the water would then flow into the cylinders. Those cylinders would hydrolock.

The base of the injector is sealed to the intake manifold by a rubber O-ring. If the O-rings are damaged or missing, there would be a huge vacuum leak, and the vacuum could suck the water into the cylinders. But very unlikely all 8 injectors would have this problem. And I don't see how the water could be sucked out by vacuum, unless you pushed a hose all the way to the valve.

Something doesn't make any sense.

 

Do you have a thick rubber weatherstrip between the top of cowl and the bottom of the trailing edge of the hood? I removed that weatherstrip in attempt to let hot air out of the engine compartment at the track. When it rained, water would drip on the PCM and the back of the engine. Needless to say, I reinstalled the weatherstrip.

 

I hope I am wrong, but this sounds so bizarre that it is some kind of a bad joke.

With my limited knowledge, it just doesn't sound like a engine could be running with water inside the intake, mixing with oil and vacuum suction etc. and still be running for a length of time to accumulate 1.5 gallons of water !!!!!!

This is pretty CRAZY !

He also didn't answer post #7 and #10 yet.

 

So if you know that whenever it rains your engine gets wet, why aren't you addressing the problem ?

Why wouldn't you at the very least put a cheap plastic cover over the entire car!
Summit sells them for around $10. You could have taped the hood and cowl vents off.

Wouldn't common sense tell you to do something, anything to prevent this?

I don't believe this is real...........

yea I couldn't believe this post,if that person is trying to solve this problem they would have signed in,but I think they are just screwing with everybody n wasting everyone's hard earned time. Let's move on
