Me and my car were cought in a flash flood it dosent work anymore ( is there anything I can do?

WanganDevilZ

Any water in the interior of the car?

Sounds like it's time for a motor swap now

Male

Yes an I believe that some water got in the intake system

cbaumy34

L28et swap time its meant to be! Sorry to about the car on a side note but if it happened to me it would be my excuse to do a swap because there is a great chance ur engine is toast

Male

FML! And yes thats exactly what I was thinking and ive bein realy considering a rb20det because I can't find a l28et

Male

The mechanic told me it might be hydro locked or somthing like that and to wait 3 days

NismoPick

Wait 3 days? For what? The rust to start in?

Pull the intake boot off & clean / dry.

Pull the spark plugs and crank the motor... that will get any water out of the cylinders. Then do a compression check.

If you shut off the engine right away in the water, you should be ok. I had several friends dunk their cars in lakes in high school.

Male

I took off the intake filter and drained the water and I'm about to do that and the car died on me in the water and wen I try to start it it just dies on me dosent even atept to turn over

WanganDevilZ

Best way to prevent rust and other nasty stuff, I'd take the head off and personally collect all the water out of the cylinders.

Were you on west street?

Male

By 21st and amidon

Murph Z32

Ya it gets bad over there too.

Male

Yey! Rb20 now I need to start saving But I don't know if I should sell the car and start over with a 240z or just swap the motor

Male

Wait is my engine officially dead now ?

WanganDevilZ

In so many words


The Rb20 will not swap directly over to the S30 Chassis, there is a website that sells motor mounts for the Rb25/26, but not the Rb20, you'll need to have them custom made for the S30 Chassis

Now, the Rb25 will make your vehicle fly down the road, but the 20 is a sufficient replacement

Sorry about your motor, doing a complete overhaul would be a good option, but for a new motor, an extra cam, and better parts available, I'd do the route again if I could

NismoPick

Why don't you do a compression check before ***-U-M-ING the motor is dead?

Male

Well I'm letting it dry out side intell my battery is charged so I can try to turn it over

There is no reason to pull the head or do anything drastic. Make sure the water is out of the intake, pull the plugs, blow some compressed air down into the cylinders to get most of the water out (you can spray some WD40 in them to displace the water). Pull the distributor cap, and dry out the distributor. Crank it over a few times, then put the plugs back in and it should start. It may not run well right away, but keep it going and it should clean and dry itself out. If it doesn't start, then some other electricals might be wet. Either wait a few days for them to dry or start blowing some compressed air around the relays to dry them faster. If you just let the car sit, then you might have a problem with water rusting in the cylinders, but if you crank it over a few times each day, the water won't have a chance to do that. You should check your oil too to make sure you don't have water sitting in your pan. If you do, remember the oil will sit on top of the water, so you can pull your drain plug and let the water out, when you see oil start to come out you can put your plug back in.

Male

Ok remove plugs then blow compressed air then spray some wd40 then remove distributor cap then attempt to turn over?

Male

And I don't have anything to do a compression test

cbaumy34

Stop by the good old auto zone and grab a compression tester. saving this engine will be the cheapest route for you. .. but confirming its dead will help you in your future plans for motor swaps.

Male

Ok I think I blew a fuse because I went to oreilys to check my battery and it was fine and when I plug it in it has no power and no lights turn on can you inspect them by looking at them?

NismoPick

Yerp...

Also check the fusible links. And make sure the ecu still lights up (the ecu doesn't like even a drop of water).

There is no reason to suspect you have a bad engine. Don't buy a compression tester yet. The reason the mechanic told you to wait a few days is to make sure all the water is dried out of the electronics and connectors. 9 out of 10 times, in this situation, you have fouled your electricals and they just need to dry. Blow out your distributor cap and the distributor until they are both dry. Put the cap back on. Now you need to trace down your bad electrical connection. It won't hurt the engine to wait a couple of days for it to dry out. If you want to buy something, you can buy some electronics cleaner or starting fluid and use it to dry your electrical connections. Disconnect your electrical connections and spry down both sides of the connections. I'm guessing water only got about half way up the engine, so start low and work your way up. If you have a multimeter, you can check your connections that way in order to find which connections are bad (this would be the "correct" method). If all else fails, I can come to you on Tuesday and bring you the 280zx parts, and look at your car. You've got my phone number, give me a call so I know what tools to bring. Also, if you want to call me anytime, go ahead. -Kyle
