I pressure washed my engine...

I then decided to rebuild my carbs (dual kads). I pulled my intake manifolds, it's a single port engine, while I was removing the intake manifold gaskets I noticed water in the heads.

Not much water, I was able to wipe it out with a shop rag, but I'm a little concerned water water .may have gotten in one if the cylinders. Should I pull the engine, exhaust, and heads? Or should I rebuild the carbs and start it up

If it's just been a few days start it up.

I ended up pulling the engine...I have a leak, I'm suspecting it is the input shaft seal.

I pulled the heads on 3 and 4 side and there wasn't any water...hopefully it isn't in the crankcase lol

I'll drive myself nuts to the point i split the case jk lol

Drain the oil and you will know.

A lesson learned, & the 2nd worst thing you could do here is to ignore that water.
Whether or not there is a next time - just pull the plugs, roll it over a few revolutions, then spray a dose of Silikroil thru plug holes into each chamber & repeat rollover.
Change oil, install plugs, light the fires & then be sure to warm it up REAL good.

I'm gonna guess that you probably hit the carbs with the pressure washer.. causing water to run down the intake and into the head past whatever valves were open..

pull the plugs, crank it over with the starter a couple of times, reinstall plugs and it should be fine..

I hydro locked mine last year because we had torrential rains one weekend and without the rain tray installed on my decklid, my dual weber IDFs sucked up enough water through the filters to drain down the intakes.. Pulling the plugs, I watched about half a cup of water shoot out of the #1 cylinder and probably a 1/4 cup shoot out of #3..

Now I run a rain tray and haven't had any issues with water..

did you remove the rockers when you pressure washed?

Also, did you remove the oil cooler when you pressure washed?

Guys, if you are going to pressure wash the engine and it is not apart, seal all the areas where water can get in. If you remove the oil tower, have a plate torqued down in it place before applying water to the case. Remove the rockers so all the valves are closed.
