1.6 engine/hydrolock question

Do you suppose you could hydrolock an engine if it was full of....say...gasoline?

Some of you may remember my 1.6 problems I've been having. I got a low mileage 1.6 engine that had had the crank case and block filled with gasoline (by mistake). I'm wondering if I should take the head off before I install the engine to make sure the valves are not all bent to hell. But, I know nothing about re-installing a head. I have a new head gasket. Should I take the engine apart and do a visual before I install it? I never heard the engine run so I don't know the status. I do know it has about 20K original miles on it. It's complete and ready to install (including the adaptor plates). I'm wondering if I should just take the afternoon and install it and hope for the best. If it doesn't run I can always re-install my 1.3 back in....

What's your opinion?

Re: 1.6 engine/hydrolock question

How did someone mistakenly fill the crank case with gas? If the motor was not run with the gas in it, it should be fine. If they tried to start it, they could have wiped out the bearing surfaces, or washed out the rings. Compression test it, and if its above 180psi, it should be ok. Not much worry about hydro-lock, as the pistons would displace the same amount of gas no matter which way the engine cranked. Also, there would be pockets of air under the cylinders that would compress as they went up and down.[img]/wwwthreads_images/icons/wink.gif[/img]

Re: 1.6 engine/hydrolock question

It had a Weber carb on it and a fuel pump that occassionally primed it. Well, the person who owned it before me never ran the car for 8 months and the battery kept it's charge. So, it kept priming the carb which eventually led to the engine getting filled up with gas.

Re: 1.6 engine/hydrolock question

hope nobody tried cranking it...that sounds pretty odd though...because the fuel pump should only get juice w/ the key on? right?

id pull the valve cover off and the plugs then turn the crank by hand and watch the valves go up a down or not go up and down a compres check would be nice
