Too much water. distributor, or clogged exhaust?

[Brett06]

Ok so this Weekend i took my 80 through about a three feet deep of watery mud in a rutted out hole about 30 feet long.

i got through it but in the last few feet the engine started a major loss of power, not long after i saw my hood vanish under the water the engine began to knock with every thump of the piston. at the same time it slowed down drastcally and clawled out of the hole. after wards the engine was having trouble and a few times i died when i gave it gave . it idlled really rough for a while and it was hard to get it goin fast at all.

when i had it running it spit a bunch of mud and water out of my exhuast. :whoops:

also the air filter was fine, no water or mud in there.

eventually i let the engine sit for about 10 minutes and idle
for a while it was rough but after about 5 minutes it randomly started idling smoth. so after that point i got in and havent had a problem since.

i was wondering if anyone else has had any similar issue happen to them.
im thinking it may have been a distributor lead but idk.
if it was a disributer, is there any way to seal it off so i can go in deeper water?

tell me what yall think -Brett

I think you oughta check all your fluids!

i had similar troubles with my 80. on the base of the dizzy there is a breather hole. i siliconed a breather hose into it, and have never had a problem since.

e9999 ya i got my oil changed andi ive checked everything else and it seems to be ok.

but its seems i came out better than everyone else. my friends with a ford 150 with a sixinch lift and my friend with a wrangler with a four inch lift went through it. and now both of their gearboxes are jammed in fourwheel drive.

i laughed, aww the joys of alltime 4

Ummm.... don't laugh too loud. Full time 4wheel drive transfercases are just as prone to water damage as part time cases.

Have you extended your differential breather lines? If not, you've probably got water in your front and rear diffs, maybe your transfer case.

Your wheel bearing grease might have water in it too, now, so you might want to check.

 

[Brett06]

ya i checked by bearings and their fine, but is there an easy way to check for water in diff and tcase, also what lines would i use to install longer breather lines?

 

[Rich]

After the truck has been sitting at least overnight, drain some gear oil from the diffs & transfer case. If water comes out with the oil, or if the gear lube is milky, then it is water contaminated.

1/4 fuel line works well to extend the existing breather lines.

This discussion begs the obvious question from deep water rookies like me:

Short of a snorkle, what modifications should an 80 owner make to help with water crossings?

The breather extension seems like a must-do mod for any 80, regardless of deep water or no. I did this one already.

The breather hole on the bottom of the distributor is news to me. Plumbing that seems like a reasonable idea.

Any other recommendations?

Hayes,

This thread discusses things to do when fording.

==============================================

Tips in fording water:

Both my cruisers have a fording depth spec of 70 cm or 27.5". I have never measured it, but I think it's the level where the axle and transmission breathers end.

I've driven through much deeper water (coming over the hood) and with the proper precautions and modifications I think you can easily prepare it for something like 40" fording depth

1. extension of breather lines. Purpose: prevent water entering the driveline and mixing with oil. To my knowledge, the following items have breather hoses:
front and rear axle, transmission, transfer case, diff lock actuators front and rear, winch. You would replace the attached hoses by longer ones and run those to a high location in the engine bay or, like I've done on the 74, drill holes in the air filter housing, fit with nipples and connect the hoses there.

2. move the air intake higher by adding a snorkel. Purpose: prevent water being sucked in the engine and damaging or destroying it.

3. after a water crossing, lubricate driveline and steering. Purpose: minimise water ingress and deterioration of grease. Keep a grease gun with the right grease (NLGI.2) handy so it is not put off. Use grease with the best water repellant properties (typically with Molybdeen-disulfide doping).

4. If you cross water regularly, you probably want to repack the wheel bearings more often (half the interval, and check if grease shows water contamination).

5. if you have a petrol engine, waterproof the ignition components. Seal as much as possible or, minimum spray WD40 or similar on the electrics that will see water (immersion or splashed).

6. Check sealing of lights. Water ingress quickly corrodes reflectors. I have all my lights sealed with silicone. Have not seen a problem with pressure differences (opinions vary). Most Toyota lights have a vent tube that points downward. Add a short hose to extend it further.

7. Check the fuel filler cap for tightness and that the pressure relief valve works.

I may have forgotten a few details, but this will prevent the more serious problems.

Then there are a few driving tips:

• Switch off headlights and wait a couple of minutes with the engine idling before entering the water so hot items can cool down a bit.
• Walk the crossing so you know / feel what is under the water (rocks, holes, bottom consistency).
• Switch the heating / AC to off and the selector to recirculate to prevent the fan sucking in water.
• Don't enter and exit the water always at the same location. A hole will develop.
• Put up markers to indicate your best line to follow
