Re: 1gm10 low oil pressure after changing water pump
the water pump to my memory is driven from the motor and not a pully. Correct? If so, then the second time you checked the oil, you found water again? Am I reading your notes correctly? If this is true, your inner seal in your waterpump is shot an allowing water to enter the oil. In any case, your best bet is to rebuild the waterpump, kit about 50 bucks, replace all hoses, inspect your exhaust port where the water mixes to cool the exhaust, most are eaten away. Your front and rear main seals most likely need replacing as well. If you buy a complete gasket/seal kit and replace them all you will not regret it. The engine is small light and simple as a lawn mower engine. The manual tells you step by step how to take apart and put back together. I have a Flicka an it has as Yanmar YSB-8 engine and I plan to rebuild it as I am restoring it now. I also have one finished in the water getting the bugs out for summer use. If you do a partial, you will have something else leak, bite the bullet and also get new pencil zincs for the motor. been there with this thread. look up your local yanmar dealer in your state and give them a call for parts as they got them. good luck!
