OIL DRAIN PLUG?

[Big D]

Tony, Mercs or Crusaders no problem. No need to insert an extraction tube down the dip stick tube so you get full flow from a much wider tube to begin with. Mine, I set it up with the smallest tube supplied which I think is less than 1/4 ID and walk away for a while, that's how long it takes with oil hot, manual vac pump and electric commercial unit tried. It's just so much easier, cleaner and faster from the bottom of the pan on an older Chrysler.

Larry...is this what your talking about?

The blue tube is the oil dipstick tube. The brass fitting in between it and the oil pan was added later for the oil change system. The black hose runs to the mounted oil changer pump, which sucks her dry in 7 seconds into a five gallon bucket. But this system is very expensive. I think what your talking about comes standard on most newer merc and volvo inboard/outboard gas engines. It's just a hose that runs from a fitting just like mine about 14" up and attaches to a clip. There is a plug in the end of the hose. But you still have to hook it up to a pump, just alittle easier. Using the dipstick tube to suck it out is fine as well.

I think that this might help you do what you want to do. I work for a high end car company as a technician and have used these with out any problems for years. We use them in heavily modified cars where the drain plug access is blocked. It is like the t block in the picture posted earlier but is has a spring loaded locking valve. In the picture that was posted earlier there is no valve. If the rubber hose springs a leak all the oil is dumped in the bilge. look at the n series valves the have hose fittings.

Hello gang,
My 360 chryslers have a removable dip stick tube at the pan and when removed I can put a small hose in and siphon the oil out. We use a plastic bucket with a 12volt pump attached to the lid and a small hose in the pan. Oil should be hot to get the best pumping action. Works great and I can empty both engines in the bucket.

i have the same drain fitting on the front my chrsyler 318 and when i first got the boat i thought yeah that will be great i could attach a permeant hose here and suck out the oil. well after i did i could not get squat amount of oil out due to the engine angle. so back in the plug went and now i take and screw out the dipstick tube at the block and insert a piece of copper tubing that i can bend and then attach that to my mitivac. works great.removing this allows a bigger suction tube. i would think very hard about putting a piece of plastic tubing in there. especially if you have warmed up the engine. if your not careful you could insert it to far it could actually bend up and get melted on to the engine block and then your stuck. who knows on what. thats why i use a piece of copper in there.

Ron, all,

Yes, thank you for the info. I assume the drain is in the rear of the pan, from the looks of it, good location for it.

I wasn't planning on using plastic tubing for the tube, most likely copper? But, I'm not going to put anything in there until I know, what, is in there. The pan may have some sort of baffle that the tube would have to run over, this along would stop the plan.

I, for the life of me, can't understand the thinking of engineers when they design a marine engine, knowing there will be a slant to the engine,,,,not providing a drain at the lowest point in the pan? I guess, being really smart, doesn't mean, common sense goes along with it.

But as with most I do, I'll mull it around in my head for a while, and see what pops into it. Time to do some Google searches for pic's of the pan.

g36,

You mentioned that you had the same front drain plug on your engine, and I was wondering if the majority, if not all the oil is laying to the rear of the pan, and did any oil come out when you removed the plug?

If it were the case that the oil only reached a level just below the plug, that, that would be a good place to place a tube into and pump the oil out. Then simply replace the plug and fill.

If the oil is a little below the plug, all I would have to do is remove the top step, remove the plug, place the tube into the hole and turn on the pump. I would have greater control of the tube, being able to rotate and place it at the lowest point in the pan.
So, could you shed any light on whether or not oil would flow or did flow from the plug when you removed it, in an excessive amount or none at all?

Perhaps that's what the engineer's had in mind, when they placed it there?

Thanks,

Larry

since you asked
not much oil came out. yes the majority will be in the rear due to the slant. the front of my engine isnt all that easy to get to. on my 2 engines the oil dipsticks are accesable very easily becasue they are both inboard on the engine so it is very easy. i was going to attach a permeant fitting so that was what i was doing up front. if you cant get to where the dipstick is attached at the engine block i guess you could snake a tube from front to back but it would be much simiplier to just enter the dipstick hole since it is already in the correct place for most of the oil. i dont know if you planned on leaving something in the pan from the front but i wouldnt feel good about it on my boat. maybe if the pan was off and it could be secured. it doenst take that long to warm the engine and suck it out of the dipstick.

g36,

Thank you, your info has been most helpfu.
