Problems with EK4 in the rain ???

[Han17]

I am having problems with my 95 Civic Ek4 when it rains and it is very puzzling.

Just so you know whats happening I have an oil leak and a clutch fluid leak but i know where they are leaking from and have my car booked into Honda to get them sorted.

Now the puzzling part is, when it rains and only when it is physically raining, my car starts to bog out at about 3000 rpm and then the engine cuts out. By bog out I mean it starts to lag massivly and just sounds like there is water being taken on somewhere. I can then wait 5 or so minutes and it will start again but it does the same again after a couple of mins if it is raining. As soon as it stops raining it drives fine.

Any thoughts???

Is your air intake OEM? Or modified in any way?

[Ek4Vtir]

sounds realy bad recommend you take the car to the mechanic for full check up.. Common sense at if u keep driving it the problem is gonna get worse, therefore costing more $$$ safe then sorry mate

intake is a CAI but it's never had this problem before in the rain neither has mine that has a similar intake

[dupac->]

check the front bar generally water will sit in between there and the splash tray while raining.

cai are overatted.

sri + stack way to go :thumbsup:

Yeh which is why ive booked it into honda to be sorted. But i gotta drive for work so I'm kinda screwed if it rains! It's just annoying cuz i don't know whats happening so I'm open to all suggestions

Intake came with the car when i bought it :P

Remove half the CAI piping when it rains, so the air filter sits in the engine bay. Not the best for performance but give it a try and see if you still experience the same problem.

[Han17]

yeh i was thinking about even putting my stock one back on to see what happens...

[dupac->]

i cant see how water could enter the engine bay.

but from where the cai is usually located in the ek4's water seeps through the front bar under the headlight and sits there where the pod is located.

so yeah put back on the stock box if you got it..

happening in heavy/constant rain?

or any kind of rain?

[Han17]

any rain... and as soon as i get to a clear patch its all good again.

Yeh i'll shove my stock back on and see if it rains for me to test it out..

I have an injen cai that is feed by a bellmouth mounted in the bar and i've never had any problems with water entering even when driven during really bad rain

Hannah if you want i'll put ur airbox back in thoe to see if it solves the problem

[TONTON]

yeah def your cai, just remove some piping to make it a SRI or stock airbox...

keep us updated!

yeah i've run a cai aswell....... in my ek4..

never had a problem with rain or water for that matter.. even after a carwash its fine..

but hannah seems to have this problem in the rain only?

my only suggestion.

change the intake and then go from there.. and wait for the rain LOL

[dupac->]

check if your splash tray underneath the front bar and all that especially where the pod filter is located to see if in still intact.

if theres no black tray there that could be ur prob? splashing water?

yep splash tray is intact but she has no inner gaurds same as mine

[Han17]

yeah the guy who had the car before me never had any problems with it and it was all fine in the rain etc up until a couple of months back (honda supposedly fixed the problem).


Hannah if you want i'll put ur airbox back in thoe to see if it solves the problem

Thanks Darryl :P tho this time i really need to watch you do it so i can do it again at a later date...

[JasonGilholme]

i doubt its intake. it could be something electrical.

check the O2 sensor and its plug. its pretty close to the road and may be loose and getting wet/damp.

it would also explain why the problem clears up quickly when it stops raining as the heat from the exhaust would dry out any water thats cause the problem.

i doubt honda will be able to find anything to do with your problem in there nice dry garage..

[DLO01]

Its not the intake. Maybe something electrical or sensor like Jase said.

[ek4-guy]

hahaha good minds think alike my amigos

[trism]

yup, its electrical

especially if it only started happening after it was ****ed around with by honda

[Han17]

ive had a couple of problems with the electrics since i bought it but just small stuff with the speakers... so it really wouldnt surprise me if it is electrical.

[vinnY]

just a thought, cracked dizzy cap letting moisture in?

[ek4-guy]

just a thought, cracked dizzy cap letting moisture in?

honda just replaced the coil i hope they would have noticed an aged about to crack dizzy cap

[Limbo]

i have my cai in the front bar and no issues

[Killa From Manila]

[RtN]

i have my cai in the front bar and no issues

same, i have injen i think it sits like where the foggies are! it's all good in rain. and when i had a mugen bumper on = massive hole exposing the CAi it was all good too.

[ek4-guy]

i bet u it wont rain nemore :P

lol i'll hose it

[Han17]

i bet u it wont rain nemore :P

haha knowing my luck it wont!

[tiamo-90]

rain dance :P

[Han17]

UPDATE:

I took it to Honda on Friday and they sorted out the oil leak and I have to replace the Master cylinder for the clutch fluid leak.

As for my main problem they cannot find anything wrong with the electrics and are pointing their finger at my air intake as many people told me they would. I am going to put my stocky back on there and look for some wheel guards I can chuck in there and see what helps.

So there's my update for now. I'll keep posting with updates on what happens :)

[Han17]

ok so i put .. sorry Darryl put my stock intake on my car.. and its fine.

[trism]

odd

figure out where the water was sitting?

[Han17]

the filter was drenched inside out.. so im just hoping it hasnt sucked too much water up into the engine :S

[omgzilla]

I'd be thinking that due to having no inner guard liners etc the water is splashing up onto your filter. The engine is then having 'breathing' problems - not able to pull enough air through the water soaked filter and starving of air, creating your 'bogging' in power. As it dries out - 'breathing' is returns back to normal.

I believe it would be more along the lines of my above statement, rather than it actually drawing water into the engine. You'd find that water will only really be sucked into the motor when in filter/inlet is completely submerged in water. Especially with a CAI (long inlet tract) there would need to be alot of vacuum to be able to pull water droplets up and along the piping, i would think.
