Question:
My Poulan Wild Thing 2375 Type 6 leaks bar oil when in storage. Could this be a seal leaking in the oil pump? If so, is the seal replaceable? If the problem is not a leaking seal, what might be the problem?
Answer
Jerold,
There are no seals inside the oil pumps, the suction & discharge lines are connected to the oil pump. The oil typically leaks in one of three or maybe four places, The easiest way I found to detect where the oil is leaking from, Is to place a piece of newspaper on a tray or pan (ie. like a cookie sheet), make sure the bottom of the chainsaw is completely dry & clean of oil, then set it onto the paper. You may need to check it every day or every other day, and as soon as the oil starts to leak it will leave a stain on the newspaper. Here are the four places that you will probably see oil: (1) Looking from the handle towards the bar, on the left side of the chainsaw, directly below the oil fill cap. I have found this problem on a number of chainsaws, and I would have swore it was leaking out of the oiler, but nope it was a bad seal on the oil cap, so replace the seal or cap. (2) Next place you may see an oil stain is directly under the bottom front of the chainsaw, this is where the suction line is attached to the bottom of the oil tank, and there is a seal grommet built into the suction line, If this is leaking however you may need to do a considerable amount of dissassembly to get to the suction line, you may need to replace this line. (3) The third place too look for a stain is on the right side of the chainsaw about center, where the oil pump is located. You may have a bad suction or discharge hose fitting to the oil pump, they are both located there, you will need to remove the bar, chain, clutch, and oil pump to get to the ends of these hoses, and see how they are connected to the oil pump. There are a couple of different ways that they might be connected depending on the type of oil pump. In any cases the connections have to be a good tight connection, and may require replacing the oil lines, if they are damaged or deformed. (4) The last place that you may see an oil stain on the newspaper is directly on the right side of the chainsaw under the clutch cover, this oil is typically dripping off the clutch cover or from the residual oil, that runs back in the bars oil groove after a chainsaw is shutdown, This typically will not be a lot of oil, and should not be draining your oil tank, but may show on the newspaper as being worse that it really is, and usually just requires wiping it off with a wrag or shop towel.
I hope this helps, and please don't disregard the seal on the oil cap, that one cause me to search for a while because I couldn't believe that so much oil could leak from the cap seal. Also some cap seals can be removed from the cap, and then simply turned over and re-installed, and fix the problem, or you may need a new cap seal. Also, I forgot If either of the hoses are split or damaged then the oil could be leaking from there, but I have not seen too many of these problems.

Agree with Karla for things to check. Now I personally have seen the oil pump piston and cylinder so worn that they leak on so saws. They are basically metal on metal contact with a thin oil film lubing the works. Once worn enough the static seal no longer holds the oil back and it simiply seeps around the piston/cylinder contact area.
If you not to find the leak fairly easily you may need to an UV dye leak tracer but most leaks are can be found without if you pay close attention to details.

Thank you Eugene.As I told Karla, I hope it is just the cap seal.

Karla, thank you for the reply. I'll do as you suggested about placing the saw on clean newspaper. Hopefully it is just the cap seal.

Hi Karla, I did as you suggested and cleaned the bottom of the chainsaw and set it on newspaper yesterday. This morning a spot of oil about the size of a quarter showed up at the right front corner of the saw and there is oil in this area on the saw. There is also oil around the square cover on the bottom of the saw. Is this Place 4 you described in your answer? The amount of oil is minimum since I cleaned the bottom of the saw, but my experience has been that over a period of time it has been more than a minimum amount that has collected in the bottom of the saw case, but not enough to drain the oil tank. Thanks for your help.

Jerrold,
I did get your recent reply, and sounds like you may have two leaks, similar to the one in this "Youtube" video, maybe still the oil cap seal, and also the hose connector fitting behind the chain guard. see video.
Here is a "Youtube" link, he is using a similar technique to my Newpaper technique, on another Poulan model, so maybe this will help:

If you have a similar metal plate, called a "chain guard", you my want to try what he did, by pushing in on that part. Also I still would not discount the seal on the oil cap, because the oil can dribble down from the cap and follow the plastic case housing, and then drip off at the lowest point. Anyhow, I hope this helps and you will need to do a little more investigating.
I hope this helps,
Karla
