Flooding rain got in my tore apart 4.0

Hey guys alot of you have probably seen the threads on my freeze plug job. I got the plugs in a few days ago but rain has halted the project since. Today the flood got bad enough to make a river through my yard that has splashed high enough to get a bunch of drops on top of my valve cover. Being as the intake and exhaust manifolds are off I know some must have gotten in the intake/exhaust ports. That and it also must have gotten in through the pcv valve elbow holes which were also open. I don't think it was much because the hood was down, but some definitely got in. What should I do at this point? Have I destroyed this engine?

You'll probably be OK but you may want to check the dipstick to see if enough water got in the top of the valve cover to register. Maybe change it out if it did and/or dump some clean oil in the valve cover while sealing those holes for now. Maybe shoot some WD-40 in the exhaust/intake ports since it was developed by NASA for displacing water.

BTW, when you go to start it with everything back together pull the full pump relay and let it crank for a minute or 2. That way oil gets back to coating everything before it fires right up w/o lubrication.

Surprised you don't have everything plugged up on your engine down there? My brother lived in Coconut Grove and we visited him every year for 25 years. One night we went to a marina and I set my bottle of beer down for a few minutes. Ever have a 1 1/2" crawling palmitto bug in your mouth?? Doesn't take very long to spit out!

just undo the oil drain plug enough to let it start dripping into a glass or glass jar and if there is water it will be at the bottom because oil floats on water .

I doubt very seriously you have done any damage since you haven't run it yet .

If you do have water in the oil you will just need to drain the oil .

Report back here if there is water and how much and I will be more detailed on what exactly to do .

Ever wonder why they die so soon after the calculated, "go to the light" entry? Mites. Mites attack all the soft joints in their exoskeletons. That or the cup of raid most people spray on them.

I know a guy in Houston who is scared to death of those huge flying cockroaches (palmitto bugs) and to make matters worse his cats bring them inside to play with! Lol!

Like you said Zee he has to kick his screen door bottom before opening it in the dark. Interesting about the mites coralman.
