Well I was out 4-wheeling today and came across a pretty big mud bog so I decided to go through it. I was in first gear going about 5 miles an hour, as soon as I hit the mud bog I floored it and about a split second later my engine shut off. I let it sit about 10 minutes and it still wouldnt turn over so I assumed it was hydro-locked. So once I got pulled out of there I removed all the spark plugs and got pulled down the street with my truck in gear so all the water would shoot out of the cylinders, after it looked like all the water was gone I put the plugs back in place and fired it up. It hesitated but started up and sounded like a damn lawn mower, it's idleing at about 600 RPM's but veerrrry shaky, sounds like a thrown rod or a valve. I shut off my motor immediately and walked in front of it to notice ALL my oil pouring out of it, havent found the location yet. I'll have to wash it down and look at it in the morning but I was wondering that if this was caused by a hydro-lock what could have broken? Thanks. BTW, heres a couple pictures.

yep sounds like it sucked in water and trashed your motor

kyle_22r

if you're losing massive amounts of oil my bet is that you punched a rod through the side of the block.

Elton

now would be a good time for the 3.4L swap

leebee

ouch! thats gonna cost ya! looks like you have some work ahead of you, i agree, 3.4 swap would be the way to go. good luck, keep us posted on developments.

Running a aftermarket open element filter didn't help out your situation much

4mydogs

I hate mud.

Red3.slow

Yeah the aftermarket filter probably lead to your engine's demise. I got stuck in a very simmaler situation except the water was slightly deeper (3 inches of water inside, pain in the a$$ to clean up) I got a little water in but I hate to say it but i think the stock air box saved me.

Well the ÅÅÅÅty thing is I put that air filter on about 2 hours before I went into this puddle. I think once my new engine is put in I'll be buying a snorkel. I dont think I'm going to go with the same one, I'll probly do a 3.4 swap, does anyone have any detailed guides to doing this swap? And also, where should I order a rebuilt 3.4 from? Thanks.

Water doesn't look that deep really. If you had gone in easy, probably would have been OK... The entry is when you need to be most careful, once you get in and leveled out, THEN you can get on the skinny if you have to!

Elton; the search ID's expire after a few minutes, it's not practical to link to them. For example, If you click on that link now, it'll show nada.

You'll need to post links to the threads themselves...

Elton

i didint know that guess next time i wont post a link .....just search for 3.4L swap

{hijack for tutorial}

Yeah.. it's based on how the backend of the forum software runs.

When you search, it actually builds a temporary "table" (database) of the results. That way, you can still have access to it while you're looking through the options. But, that table takes up disk space, so to keep things neater and tidier, the temp tables get purged (deleted) after a while. I think it's 60 minutes...

who is that intake made by? Would you want to possibly sell everything but the filter? If so i would like to know......sry for the hijack.

KTMR1der03

Nah I'm going to be keeping it, my dads going to have one of his friends (Mechanic) do a motor swap for us, still talking to him about a 3.4 . The air filter is a K&N FIPK.

Does anyone know what else could have been damaged from the water, I did feel a clunk underneath my foot once I got it started, but is there another part that could make a clunk, and then pour out all my oil? The engine wasnt pressure-started with a whole lot of force, so I'm wondering if something else broke instead.

Elton

you would be amazed what water does to a motor ......i used to have a 4runner with a 3.0 and compared to the 4runner im driveing now with the 3.4 it has more power than a 3.0 would ever have

Tofer

sorry to hear about that... let me know if you need any help i am in the area now. i'd like to see the 3.4 swap so i can do it later

KTMR1der03

Well I'm not going to be the one doing it unfortunately, I have no experience doing something like that to a car but the guy who will be doing it is a friend, so I can still post pictures and list problems he encountered etc.

Am I going to need to regear with this new motor?

Elton

no it will be fine...........im guessing your going to stay away from wheeling in deep water
