Alrighty, so I got stuck in some muddy water today and was able to get out under my own power eventually. But a decent amount of water got into the crankcase. The engine did not hydro-lock. Ran a quick trail before I noticed anything was amiss...
I drained the oil, added new oil, filter, and some Seafoam to help chase out any remaining moisture, but here's the deal:
My Jeep ('99 4.0L w/ AX-15) now sounds like a diesel. Bad. At idle in the driveway the oil pressure sits at about 15psi. At idle when driving the oil pressure will drop to zero and the check guage light comes on. Driving down the road to test it out and the oil pressure is a max of oh....about 15psi according to the guage. But for the short bit I have driven it, the engine feels like it's running perfectly smooth...just sounds like a diesel. Except there's no Duramax under the hood.
I'm thinking/hoping maybe just the oil pump is fuxored, but I suspect it's quite a bit more than that. Probably lifters and/or bearings. Oil pump I can do. Beyond that and it's going to a shop.
Ideas?
And no more deep water for this TJ. :doh:
