I just recently bought an r34 and it has a fibreglass vented hood. Seems to leak water into the engine when it rains and the car wouldnt move and kept stalling as the water had got into the intake (i think)

i have an unenclosed pod filter... so maybe thats the issue ?

Im quite sure this isnt a normal thing to happen just because i have a vented hoods! any ideas ? im thinking of somehow blocking the vents to stop water leaking..

- attatched a photo of my engine bay and hood

thanks guyss

i had the same style on my 33, water use to enter through the left hand corner of the main opening, would go into the airbox snorkel straight into the airbox till it filled enough to go into the intake.

I cant see exactly where the snorkel ends on yours but if it is directly above the filter or even against the side that is probably your problem, could also be that the water is getting into the electronics of the afm.

FYI i hope you bought the bonnet for cosmetic reasons, i weighed mine when i changed back to the standard one, the fibreglass one weighed 18.x kg and the standard was 15.x

Removing the snorkel and fitting a cai will probably fix it, unless the 34 bonnet weighs 5x more than the 33 i will guarantee you that there is not that much difference, i dont think real carbon fiber has that much of a weight difference.

The water is getting directly into the engine bay and onto the pod fitler and i think blocking it from breathing properly ? so i dont think the snorkel would work :( and as for the bonnet.. well i can literally hold it with 1 finger and it looks so easy to snap! so im quite sure its light asss

r34 bonnets are heavy as hell

Is there anyway i can just BLOCK the vents on the bonnet?

You could get some sikaflex and thin plastic (ice cream tub should do) and stick the plastic over the holes on the inside of the bonnet, you will have to leave a hole some where tho or you will end up with a swimming pool on your bonnet.

Since it is a non turbo for now just remove the snorkel, i doubt the heat of a non turbo will hurt power, drive it round for a while with out the snorkel if you notice a big difference in power get a CAI if not then you fixed it for free.

I think the position of the middle vent means water goes to the front of the engine its jst the left..

ANd im not sure what you guys mean when you say remove the snorkel ? the water is getting onto the pod DIRECTLY from the vent not through the snorkel!

thanks for the responses!

Well in going of the exact same problem with that exact same styled bonnet on my 33, the water would come in through the corner of the vent run onto the opening of the snorkel that sits on the rad support and then run down the snorkel into my air box, in your case onto your pod filter, instead of arguing with the answers try it, will take you not even a minute to take it off, if it does not work put it back on again.

Looks like you have the very basic water injection kit lol, can only be a good thing just needs a tune with the new setup :P

Jokes aside, is it possible the water is getting in to the coil packs? there is a big thread on vented bonnets and water issues brought up just recently and water getting into coil packs that was usually the main cause for problems.

Would that cause stuttering ? and stalling ? I just assumed it was the air filter because it was wet and when my AFM was broken it would do the same thing.

For now i just put an icecream tub over it and it seems to work :)

Removing the snorkel and fitting a cai will probably fix it, unless the 34 bonnet weighs 5x more than the 33 i will guarantee you that there is not that much difference, i dont think real carbon fiber has that much of a weight difference.

acutally it would be quite a difference;

    • Yeah well per the video it took 15s for the stock unit to start up....even if I give it a few seconds discount for starting that is at least 12 sec before you get a reverse camera if you are trying to leave a park.  The android unit is way faster, but 2016 for the stock unit is a long time ago in consumer electronics
    • Yea that’s why I said ima test them with multimeter and see the reads.
    • Only at idle. Isn’t a problem when rev it seems.
    • @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?  
    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
