We finnally got our alcohol system correct i think, BG bypass and a EB mech pump. What a nightmare.

Anyway, in the process we milked up the oil pretty good. Whats the best way to clean out the engine after doing this? Makes me really nervous to see milky looking oil in the engine.

I was thinking of getting some high detergent oil, and then running it for a few minutes on it, then changing to our regular stuff. This sound like an ok idea?

from what I've seen milky oil on alcahol is the norm. It has to do with the alcahol getting by the rings before the engine gets warmed up. I've never ran one just worked on car that did, what I was told is you want to get them warmed up as quick as you can once started and never start them for just a minute or to move them around the garage. I'm sure you'll get more replies from someone with a lot more experience than me.

If your getting your oil milky then you have more problems... It isn't normal to have it turn a milk color unless you fill the crankcase with alky. I'd just drain your oil, change the filter and fresh oil in it and go. It'll clean itself out.

If your getting Alky past the rings then there are more problems yet hobby39. All that should be burning. Sometimes if you get pulled in on the wrecker and don't have a shut off valve you can easily fill the crankcase up, or even the cylinders.

I had the throttle bypass and also ran into the milky oil problem. If you change the oil then start it up and let the new oil warm up it will evaporate any fuel left in the crankcase

Ok, we'll just change it and keep an eye on it.

I believe we finnally got it all set right. Combination between float levels and fuel pressure. We shouldnt milk the oil up again i hope.

One other thing you may think about is that standard crude oil such as castrol,valvoline do not mix well with alcohol.I say this with experience.I drag raced for 15 years then switched to turning left in a latemodel always using alcohol.Iam not sure why but the above oil even with good ring seal would always turn a little gray after a couple weeks of racing, just recently I was at our local speed shop and they were selling this oil called The Green oil from brad Penn Lubricants and told me that this oil would not turn even after several races.I thought they were full of it but believe or not I poured it in green an after three nights of racing I drained it out and it did not change color at all.I do not get any milking on the underside of the valve covers anymore either.I also noticed that my oil pressure rased 5 pounds at idle and after the feature my oil pressure does not drop like it use to.I have no connection to this company but if something is good it should be put out there for everyone.One other thing, it use to be the old Kendal GT1 from the past and it is cheap at $26 dollars a case.I dont care if anybody believes me but I dont have to worry about staining my cylinder walls or bearings like I use to.Just a thought.

if you run alcohol your oil will be milky looking, since you burn twice as much as reg fuel. you have no problems it all normal. talk to some sprint guys or late models that run 50,000.00 engines they do the same

We run Penzoil racing oil, supposedly it handles alcohol really well. Our engine builder likes it.

We finnally got the alcohol system set up properly so i think some of the problems will go away. I was just a little worried, its only the 2nd week on it.

Were planning on changing it every other week.

I looked at that website, interesting, i must admit i would preferr not to see any milking fo the oil myself.

Penn-Grade 1 Racing oil, is that what your using?

I'll try it, if its the old Kendall stuff our engine builder will be on it as well.

Yes, that is what Iam using in a Rayburn Latemodel right now. I took this off the box:Brad Penn Ind.

To whoever said that if you use alcohol in a car that it will be milky is wrong!!The only time in a sprint car would it milk the oil if the pill was to big or something wrong with the injection and on a latemodel if the float would stick or the regulator on a manual pump has something wrong maybe something wrong with a belt drive pump or fuel log or even the bypass.The only time I get milky oil is when I initially start a new engine with a alcohol carb and on my drag car when I first put injection on and the pill was too big.Once I have got the fuel system setup right I never milk the oil and If I did I would find out why because something is wrong.When I used valvoline or Castrol it would turn it dark but not milky.I am not cutting down Castol or Valvoline but they just dont work as well with alcohol.Even the best sealed piston and rings allow some alcohol in an engine.Plus as anybody who runs alcohol knows it draws moisture and thats why you get water dripping out of the valve cover breathers.Like I said since I put this new oil in it I dont get that milk look on underside of the valve covers.

We have been running on methanol for about 5 years now. We have always had somewhat milky oil when we go to change it. This is extremely normal and there is nothing wrong when this is happening. Everyone around here has the same problem. I know an engine builder that says they run synthetic oil in their motor and drain it every other week and place it in the sun with a mest net over it to keep it clean. They put it in the sun to let the methanol evaporate and then they re-use the oil. They do that once and then change oil the next time.

popper23 is right. alcohol engines almost always have milky oil when its cold due to the fast evaporation and cold temperature condensation. once it warms up it should go away. if it dont, then you have other problems.
let engine warm up good before revving it and you should never have a problem.

All I can tell you is the oil in both my latemodel and my drag car do not milk the oil unless to much fuel gets in the engine other than normal operation.The oil will turn dark but unless something has gone wrong with my fuel system I dont get a true milky oil like a blown head gasket.I run Torco methanol which has very little if any problem with moisture.We buy it by the drum and it goes straight into the car or the extra fuel jugs and it is used the night of the race.Also now that the temprature is hotter and the cold nights are gone we have no moisture.All I was trying to say was now that I use the brad penn oil which is designed to mix with oil better than convetional oil I have no more problems with any moisture.Like I said before I dont care if anybody believes me but it is used in 4 cars including mine and none of us have any problem with water in the oil or moisture on the underside of the valve covers.I dont what kinda of money you put into your engines, but I spend way to much to have water going through a $15,000 engine.I have seen what moisture will do to a cylinder wall and it is not pretty.One more thing to actually reuse oil that has been run is a little crazy, oil is so cheap and I put the kinda money in my engine that I do I have never heard of such a thing in 20 years of racing.Do you realize how bad oil picks up dirt and picks up impurities, to have a quality engine builder tell you that is something that may have been done 20 years ago.If your are going to do that why change the oil at all.The only time I reuse oil is in the military and the oil is put on an oil analysis program and it is costantly checked.I would reuse gear oil because it has no foriegn liquids being put into it.
