Default DD Clutch Question

This question involves my DD. I washed it yesterday and used the water hose nozzle and squirted water through the radiator and AC Condenser. This morning I got in the car to run to the store, the car started as easy as always but would not go in gear for me. I turned the car off and worked the car through the gears with the car off. It worked perfect. So I tried to start it with it in gear, clutch pushed in, the car lurched forward. So I started checking all the hydraulic components to see if everything was working correctly. All is good here too. For kicks I tried to start the car in 3rd gear, the car lurched forward when I hit the key, and then the clutch started working right.

I am thinking water must have gotten in through the clutch fork boot and caused this. The car does have a ton of miles on it, 194000 but runs good and drives good. Any other ideas what would cause this?

Assuming your car still has the stock clutch linkage it is mechanical...and spraying water through the radiator would certainly not affect clutch operation, even if you got some water inside the bellhousing.

I once had a weld break on my clutch cross shaft; that could be the problem. If you've got the pedal pushed in and the car jumps when you crank it the clutch is not disengaging, so something somewhere between the pedal and the pressure plate is worn or broken, pedal pushrod, cross shaft, cross shaft-to-frame bracket, clutch fork pushrod, clutch fork itself, or the release bearing.

Most of that list can be eliminated as he stated:

So I started checking all the hydraulic components...
Presume that means he has a hydraulically actuated clutch.

Also, I don't think he is asking for help with that '70 ragtop as I believe DD means daily driver.

OK then, let's try this:

Spraying water on the clutch/ bellhousing STILL should/would not affect clutch operation. If anything it might make an alreay weak clutch tend to slip, making gear engagement while running possible rather than impossible...

As it stands, if we are to assume that said DD is a typical front-wheel drive compliance-mobile then OP should (again) check all the components of the system, including the pedal assembly, master cylinder/reservoir, hose(s), slave cylinder, clutch fork, release bearing, pressure plate, etc. For proper operation....

Same as above, obviously for some reason the clutch is not properly/ adequately disengaging...

I'm wondering if you ran into a case of the clutch being stuck to the flywheel and starting it in 3rd finally wrenched it loose.

You could have a master cylinder that's slightly bypassing as well, or a slave cylinder for that matter. Does the pedal feel normal or perhaps a little weak?

Usually a weak master will be visible at the interior firewall - you'll see fluid on the backside.

The car in question is a little Honda. I drive 140 miles round trip to work so I have to have something that is pretty good on gas. I think Shark Racer hit it on the nose. I know something in there was stuck together. It has never happened before to me. I just used the water hypothesis because that was the only thing that has happened. I had never heard of this happening. The car drove normally today going to and coming home from work. Clutch hydraulics all seem the same as they always do. New slave and also new master were installed about a year ago because of squeaking noises when pressing the clutch.

Any of you guys ever hear of this happening?

Apparently, it happens to Corvettes that have sat for a while all the time...
