Changing oil through dipstick tube vs. using the drain plug

Mar 02, 2004 93 Replies

This noise has gone on long enough. It is time for me to put this issue to rest. I feel compelled to do so.

Firstly: One knows, presumably, how much oil is in the engine, because the engine capacity is listed in the Owner's Manual, and one has a DIPSTICK.

For example, my owner's manual calls for 4.5 quarts of oil. This is not -quite- correct, because the oil filter retains 1/2 quart. How do I know this? I've measured it. 4.5 quarts leaves the engine short

1/2 quart on the dipstick after an oil change, after the engine has been started to permeate it.

Nextly: One measure the amount of oil withdrawn from the engine.

When the filter is removed, so is 1/2 quart of engine oil. The remaining can be measured ( as I do ) by pumping it into empty 1 gallon milk jugs.

So let's put all this together now.

Before my oil change I check the engine level and it reads FULL on the dipstick, or down 1/2 quart or whatever.

If it reads down 1/2 quart because it was burned-off, then I can expect a) 1/2 quart depletion by removing the oil filter and b) 1 each filled 1-gallon milk jug.

If I get less than that, I know the *missing* oil is still in the engine somewhere, and the vacuum method missed something because the tube didn't make it to the bottom of the oil sump.

The remainder of this is left as a field exercise for the readership.

You pulled the engine oil pan?

Was it a $300.00 oil cnange?

Some engines had to be removed to take the oil pan out. Are you sure you don't mean the transmission pan?

You're WRONG!

If you put in 4 quarts, and start the engine, you'll be half quart short. If you put in 4.5 quarts, then start the engine to fill up the filter.

The oil level on the stick will be perfect.

Providing you are reading the manual properly, for the engine that's in your vehivle?

PS

Pulling the oil drain plug still leaves oil in: The oil pump, the lifters, the oil passages, the crank shaft, the heads have wet areas, so does the lifter valley.

It's not a bad idea, but. I don't do it!

at the risk of continuing the "noise", how would you approach an engine where the dipstick doesn't go into the block (this is the case with my daily driver). To change the oil on this car is something of an ordeal involving removing body panels to get at one of the oil filters and one drain plug, and removing a bit of other stuff to get at the engine drain plug and a second oil filter. It would be nice to just suck through the dipstick, but it wouldn't work as far as I can see.

oh, free "buy it yourself" donut or beer if you guess the car from that description

You just called me a liar you F*CK. Don't you ever do that -again-

You are mistaken

You are mistaken, or a mistake. The Jury is still out on this matter.

========================================================================

Having recently changed my oil and filter, I just went out and checked the level AGAIN in the garage which is level.

There is an upper and lower hole in the dipstick. The oil level goes smack Dead-On at the upper hole, which is "Full"

You call me a liar. That's after pouring a FULL 5 QUARTS OF VALVOLINE

5W-20 into the engine.

This is a V6 12 valve Vulcan engine, 182 cubic inches displacement,

152 horsepower.

You come over here, and put your money where your mouth is. I bet you Here, in the n/g, $2,000 cash, that you are incorrect and that I am right.

Don't bring anything but cash. A check from you isn't worth the paper it's written on.

According to Chrysler, your Plymouth doesn't have a dipstick! It has an Oil Level Indicator, Part # 662 598, 37 through 48

As for the cad, it's bad taste to mention gm products in the same sentence as Magnificent Mopars..

You guys saying my memory is shot? LOL, maybe so. My position is untenable and it would be pointless to attempt to defend it...besides I have to walk to the store to get my Geritol, the snow's already 5 feet deep and those hills are are getting higher...

This is Usenet, and you need to cease with the nonsensical bravado. It makes you look silly.

The first car with two filters that comes to mind is a Ferrari.

My challenge stands. Put your money where your mouth is folks. I will set the parameters anywhere you like.

Wanna bet $20? No problem.

$200? No problem.

$2000? No problem

$200,000? No problem.

Step right up and take advantage of this once in a Lifetime chance to screw yourself with your own putz.

Love it!

Thanks for your good natured humor, Arthur.

Bold words, considering LG uses recycled electrons.

Whether or not the transmission uses constant-mesh planetary gears, or constant-mesh gears on parallel shafts, the real questions are 1) does it use wet clutch packs or bands that shed clutch material into the fluid? and 2) does it use a precision machined hydraulic or electro-hydraulic valve body that is easily clogged and jammed with clutch debris?

I already think Honda blows chunks, and this isn't doing anything to sway me in a positive direction....

But decided that we needed to get that nonsense any way.

Or not caring.

So can you, and hey, I was here first any way.

jk

Not as silly as some drooling moron creating two sock puppets and making them argue with each other... which is what I suspect in this case ;-)
