Default 97' ford f150 exhaust/snorkel

Few questions..

I go out and play in the mudd alot.. Nothing too deep but sometimes deep enough to go over my exhaust. how bad can that be? and what do you suggest? (stakes maybe)

I have water hit my air intake many times. Would it be beneficial for me?

Also, I'm think of trying to get a bigger engine. But I dont want too if mine will do. I have a 4.2L, the truck is 4wheel auto.

Thanks, Any info is help.

I wouldn't worry about mud in your exhaust pipe, but if you really don't want to take any chances, just plug your exhaust next time you know you'll be out in deep mud with a potato or something that will be able to take form to your pipe for a nice, sealed fit. As for the engine, keep the 4.2L and just do some simple mods. Start by taking your air filter off for better air flow. And don't worry about the water in your intake; it's actually quite beneficial as it cleans out oil sludge and carbon build up. Also, I put one of these adjustable power bands on my truck and will say it will woke it up. Good luck!

haha.

exhuast under water doesnt hurt anything as long as the engine is running the exhuast forces the water out of the pipe. as far as water hitting the intake thats what the filter is for. the only time your really need a snorkel is if your entire engine is under water. the rule is you can go into water as long as your intake is above it ;) but water spalshing on it i wouldnt worry about.

As said above. Underwater exhaust is just fine for the most part.

A small amount of water splashing onto your engine is alright in limited amounts. You air filter is NOT for filtering WATER from the AIR. It is for filtering dirt from the air. Water going INTO your intake is never a good thing, and even in limited amounts can lead to engine failure.

You are the best person to justify the cost of a snorkel setup. Are you really seeing enough water for that? Or are you just splish splashing around in it? You must be cautious either way, but my best guess is you don't need one.

On the 4.2L bit... 1997 and 1998 were BAD years for the 4.2L. The 4.2L in itself is such a sorry replacement for the 300 Inline.

I would feel very nervous wheeling a stock '97 4.2L, as even under normal driving conditions they rarely reach 100k without rebuilds. If you have the cash and really enjoy your sport, then I would run the 4.2L til it dies and replace with a 4.6l from a wrecked donor truck. I would not under any circumstance spend any money to "upgrade" the 4.2l

I just had to replace my engine for getting water in the intake for mudding. I have been looking for a snorkel sir my 97 f150 and can't find one, does anyone know where I can get one? Don't want to have to do it again.
