Default Hood Vents

alright so i dont know anything at all about hood vents minus there purpose, but i was curious if it would be worth my time, and which would be a better fit for my situation.

First of all, i do like to play in the mud and water a lot, so the top of my hood is wet or muddy, there is also the fact that the jeep is parked outside 95% of the time and im in colorado so there is snow, so things basically need to be water proofed or something along those lines

1) which is more affective, Propping the back of the hood, or cutting into the top and putting in vents

2) which is going to allow less water and crap inside the compartment, while stilling giving acquit ventilation to the engine

Thanks for your help in advance, here are some photos to show kinda what i am thinking about

I recently did the vents on the right and so far have no complaints. Haven't been on the trail with them yet, but I've been caught in a few heavy rains recently. I like the popped hood, but didn't want people thinking it was broken lol. It's also apparently dangerous in a head on collision or something too hah. If you do the vents on the right, just use dielectric grease on your stuff and you'll be fine. I haven't yet, but it's on the to do list.

The thread that goes along with the white XJ is quite detailed in how well it works with rain. Read up on that one. But suffice to say he made drip pans and has had 0 problems.

I would NEVER put spacers on my hood unless its strictly a trail rig. What is gona happen to that hood in a frontal impact?

Those hood vents are supposed to work pretty good though! I will be doing that mod in the next few weeks.

here's a solution to the hood spacer dilemma. if you have time and a welder you can do this.
no rain in your vents, no decapitation in a crash. thus why I chose to do this with my hood. also because I like the way it looks

still got some work to do.. I promise it'll come out nice in the end

thanks. maybe make friends with someone who has a welder and pay them $40?
I'm really happy with it. but my second option would've certainly been vents

What exactly are you trying to accomplish by installing vents? I put a set in mine to try to reduce some heat under the hood to save rubber, plastic, electrical components. My cooling system was fine, no overheating but vents don't cure this anyway. Dielectric grease on the TPS is key since they are very temper-mental about water. I did the IAC, TPS and Map Sensor plugs. Never had issues. Having water drip in shouldn't be a problem considering most of us run them through mud and water anyway. (Unless you only do rocks) The thing with heavy amounts of snow is snow in heavy amounts is quite heavy. You'll need a set up that can withstand the weight so they don't collapse. But most techniques on hood vents already done are up to the task. I have yet to see a thread where someones vents fell in due to too much weight.

Hood vents can also help with heat soak issues.

x2 on that. with my cowl hood I also got a radiator, zj fan clutch, transmission cooler, 195 tstat, new heater core, new hoses, and I'll pick up a 97+ fan when I get the chance.

dont go cutting away to cure the overheatsies

It won't cure overheating but will help it run cooler.

Well before we go in to a discussion that has been beaten like a dead horse (vents and overheating issues) lets 1st find out why exactly the OP is even looking to do this mod.

Engine doesn't run hot, just wanted it to run cooler, I have seen thing done here and there on the Forum and was just pretty much curious as to what would be more affective if i did decide to go down that path

venting is only really helpful to release hot air build up on the trail at low speeds. all the methods work it usually comes down to preference and ease of install
a good system flush will be more effective to help run cooler.
here's another innovative venting idea you may consider.
