Honda making Oil (again)
HELP ! I posted
here about a year ago about a Honda 50 HP 4 stroke outboard making oil. Well, after a new fuel pump was installed, carbs checked etc, things seemed fine for about 20 hours of run time, then so much gas started getting into the oil it started bubbling out the dipstick tube again. Dealer says it's time for a another New Pump. Now pump #3 is in for about 5 hours and it doing the same thing ! What's going on here ? The engine otherwise runs perfect-as smooth as glass- the choke is not sticking or coming on by itself--has new thermostat-none of the carbs are running rich and it is stored wiith the engine verticle,run dry on gas and the fuel hose off. There has to be know problem and fix for this engine. Changing the Oil & Filter every 5 hours is not the cure ! PS-The dealer is stumped. ....jk... |
Me thinks that you have a blown head gasket or a cracked cylinder, do,
or ask for a compression test. JK wrote: HELP ! I posted here about a year ago about a Honda 50 HP 4 stroke outboard making oil.

Nope, compression is fine. 165 lb. in all three cylinders.
All plugs are burning a nice tan color. This is GAS getting in the Oil, not water. Thanks for the reply though.....jk..... |
Under warranty yet? If yes, if no... ask your dealer to talk to the Honda
area rep. Maybe you need to find a smarter dealer to work on your engine. But until then I would gladly sell your extra oil back to the oil companies(lol)! "JK" wrote in message ... HELP !

One would think the dealer would have done the compression test as soon as
the gas was finding it's way into the oil. I would recommend you find a new mechanic, one who is familiar with Honda's and can call Honda if he has a problem he is not able to solve.

If it's gasoline finding it's way into the crankcase of a 4 stroke in large
quantities it almost has to be the fuel pump. I believe the USCG requires dual diaphram pumps with a weep hole between diaphrams. Thus when the outer diaphram fails you begin to get small amounts of fuel in the out of the pump which is VERY obvious. I agree that you should consider another shop. Since I'm unfamiliar with Hondas I don't know enough to try to diagnose the issue. On some engines it's possible to install a pump with the lever in the wrong position which can cause pump damage very quickly (immediately?). I suppose it's JUST possible there could be a carb float chamber issue allowing too much fuel to get into the engine if it is tilted just so. Pretty unlikely but a DECENT technician could certain diagnose your issue with the shop manual and engine in front of him/her. Good luck. Butch "Woodchuck" wrote in message .. . Under warranty yet?

Tom
There are more Honda's 'Broke" down here in SW FL than you would think Tom. See a lot of them with Big Damage due to broken timing belts, Lower unit failure and electrical issues due to weak wiring harnesses. This particular engine has had it share also from day ! This engine powers a trawler style boat, a ( Nimble Nomad ) which my buddy owns. He's looking into replacing it with an E-tec at this point.......jk...... |
