Unfortunatly the shipping company in the US left the ignition on. So in the 3 months it was pumping till the carb gave up and the engine got floaded with gas. When we opened the bolt from the oil pan we got 13 Liters (3,5 gallons) of oil/gas out of the 440. Could there be damage to the seals in the engine? What would you do? Just let it dry out a bit and then put in fresh oil, let the engine turn without starting it? Carsten

Change oil filter, refill with oil, pull the distributor and spin the oil pump with a drill. Spin the engine by hand or starter, change oil and filter again, put distributor back in, run it for 100 miles then change oil and filter again. You should be set to go.

When you get to that point to preoil before you pull the dist/intergear set the rotor on #8 then pull em & preoil at that position then turn the crank CW 3/4 turn till the timing marks are on TDC (rotor would have been on #6) & preoil the other head live every 24 hour block of time like it's your last day on earth

Along with the other suggestions, I would use inexpensive oil and change it after an hour of run time 2 or 3 times before putting the "good" oil in. I flooded my 440 once and I could smell gas on the dipstick for over a year, even after changing the oil several times.

There is a rubber diaphragm inside that can tear, and let fuel dump into the crankcase. Scott B. "I'm a self-made man...

Did they cause more damage already? AFAIK they didn't run it. But the carb was damaged, too so it might have been started and they got a back fire? Who knows? When we got it pushed off the truck we noticed it won't start After checking the carb we knew why it won't start as it was closed. We opened it. Put a fresh battery in the car and it started. Ran bad and got shut off after 15 seconds by us. Pushed it into the garage. then we checked everything in detail and noticed the small on the oil pick up.

Then we took comressed air and breathed it in.trying to get the rest of gas out as well as the vapors. We also sprayed some oil into the cylinders over the spark plug holes. Then turned the engine without spark plugs. Now we put fresh oil in it and a another filter. We did let turn the engine without ignition so it builds up oil pressure. Now we started it and just did let it run in idle. So far it sounds good Carsten
