Oil in intake!

[Speedling]

Ok, so, we all know we gotta watch the oil etc. blah blah.
When I purchased it, I was very careful about putting exactly as much oil in as I took out.
Turns out that was too much on the port side, and I had oil on that side. I still have to clean it all out!
I just changed the oil this year, and only put in ONE quart. Took it out on the lake last week, checked it to add what's needed, and they were BOTH OVER and there was more oil in the Port side intake again!
Now, I'm not currently running the filters, so it's not a huge deal about fouling the filter, but how do I clean up this mess? Get rid of the oil? Just keep taking oil out? Do another oil change just oil to get things right?
I have a puddle in the intake! How the heck do I get that outta there!

Ok, so most of this is probably just venting...
Would carb cleaner be any good at cleaning out the intake stuff?

First, always make sure the engines are level before checking the oil. If you are on water, that is good.

Second, I would extract with your oil extractor back to the proper level. Be sure you wipe off the dip stick each time after waiting some for the oil to drain back. If you are in rough water, you will not get an accuarate reading, of course, as the oil will slosh.

As for cleaning up extra oil in intakes, etc. I would begin with paper towels to sop up as much as possible. Yes, carb cleaner will cut the oil, but then you need to sop that up. So use that *only if you have oil in crevices or somewhere that you are worried about.

There is no way to extract to the correct level. You have to run them at cruise for until warm and circulated, then at idle for 2 to 3 minutes to let the entire oil system stabilize. Then read the level and adjust. I would take out enough to get it to the bottom of the dipstick and then run them 5 minutes or so, idle 2 to 3, and check again. But you must have oil at least on the stick to safely run it. So maybe take out a 1/2 quart, run, check and repeat if necessary? Once it is under the full mark, your good. Agree with sopping up as much as possible. They must have been overfull when you changed it without having been ran between. I'm not sure on the intake sprays...so won't add anything to that discussion.

I think adding anything to this will only compound your problem. I used a screwdriver to push paper towels into the crevices that had oil. Cleaned up well.

I'm curious as to what type of oil extractor your using. I ask this because I can suck out 2-2.5 quarts out of each engine. I don't understand how you could you sucked out as much oil out of each engine as possible and only out back one quart and be overfilled.

Does the engine run ok?

I am using a basic hand pump with tubes attached. In fact I used different tubing on the dump side. I got at least 2.5 out of each, but put back less than that with intent of filling on the water. I brought an extra 2 quarts, one for each engine, but they both read over full already! I hope to check again on water this weekend after I pulled a half out of both.

 

[txav8r]

Something doesn't add up @Speedling . Not doubting your knowledge at all here. But if the level was ok before, and you added exactly the same back, it wouldn't be overfull. If it is and something in the situation wasn't missed, you may have a fuel or water leak! Check the oil for fuel smell and/or muted color. Based on all your previous posts, I figure you know all of this and are stumped as to why. Could it be you just made a mistake in calculating how much you put in? Stuff happens. I have done 6 to 8 changes and never seen my dipstick register any higher than what it was before I changed it.

If I am doing the math right the engine had 6.5 quarts in it when you started. It seems hard to imagine the engine starting, much less running well with that much oil in it. Something seems really off.

No water in the oil? The oil from the extractor is measured accurately?

 

[itsdgm]

@txav8r @Speedling that's why I was wondering if the engine was running ok. Do you have any fuel smell in the exhaust while running on the water? Or any fuel smell/frothy mixture in the oil? Could be indicative of a stuck fuel injector or water leak into the oil making it appear to be overfilled.

Hopefully were just overthinking this and maybe you did just overfill. Keep up posted.

 

[Speedling]

Well, I think the first time I did the change, LAST year, I just put in WHATEVER I TOOK OUT, meaning, if it was overfull, I just put it back in, and measured it very carefully if I recall. There was a little oil in the intake then, but I tried being very carefull about it if I recall. So I probably OVER filled it again. It was pretty oiled up when I did it this year. I wiped everything down, and yeah, I thought I had left a full quart low to what it should be!
Maybe that was still too much?
It doesn't smell like fuel at all.
I did have ONE overheat on this paticular engine after running full throttle on coldish water for a good 20 minutes or so, and cruising for a couple hours before that (Peoria to Starved rock run). Turned off the key, started it right back up and all was fine.

I will be checking it often now and looking for anything out the ordinary!
I hope to be out this weekend mainly for making sure all is well with this matter. I hope it's just that I over filled it and the guy before me just WAY over filled it and had done his own maintenance.

Found this thread while searching for 'oil in intake'. Reason for this is because while ribbon deleting work continued today I noticed oil inside the intake. A fair amount (guessing about 1/8 cup?).
So...that's generally a no-no. What gives and is this a known issue or is there a known reason/fix? This thread was not 100% clear on cause, suggesting possible over fill on oil level but still not clear on WHY it happened.

It really isn't an issue and there is no fix per se because nothing is broken. If you put too much oil in the engine it has to go somewhere and it spits it out in the intake. To me there is only one way for it to happen...that is for someone to put too much oil in. There are so many stories of overfilling.....even dealers doing it.

You have different engines so I don't know if this is the same, but measuring the oil with the boat on the trailer cold, the oil is barely going to touch the dipstick to under the L mark to be in the appropriate range when checking on the water warmed up per the manual. Many people measure cold on trailer and fill to where it reads F on the dipstick. This is overfilled. That's why folks say only put back as much as you take out when extracting and don't go by dipstick on trailer. I've found that the range from properly measured L to H on the dipstick is a little over 1/2 Q to 3/4Q. I try and shoot for 1/2 way between L and H. This impacts how much you get out when changing and most on the MR1 should get between 2-3q.

Now, if you have a stuck injector dumping unburnt fuel into the engine, it can mix with the oil and you will have a mixture of oil and fuel causing overfill, but I don't believe that was the case here. Folks were just speculating since the OP was sure he measured carefully, but something isn't right and it's most likely human error in assessing the initial level of oil, how much was extracted, and how much was put back in. I've never seen any major damage from overfilling, only a mess and ruined air filters.

Ok, thank you @scokill. Overfilled engines is entirely likely since I did indeed change and refill on the trailer. So I will adjust accordingly now. Appreciate the clarification!

No problem I don't know about your engines as they are different. I would yield to other folks with experience with your engine. Always read the manual on how to check accurately warmed up on the water or as recommended.
