MS-310 Chain Lube Leaking----Need HELP!

I'm a BRAND NEW Newbie. I don't normally join forums; but I'm desperate for an answer/help with my Stihl Chainsaw Model MS-310. I was born & raised in the SE Woods of Mississippi; but I joined the Navy and after my Tour was up, moved to the Great Northwest to live, hunt, & WORK. After 20 years of cutting Firewood with a Husky Chainsaw, I moved back Way Down South and was advised to purchase a REAL chainsaw....a STIHL. I was further advised that in order to enjoy trouble free continuous use of my Stihl, I should take it to a Stihl Authorized Dealer and have it annually serviced. I will honestly admit, I have a problem letting other folks work on any of my equipment; but upon the insistence of my oldest son, I relented this year (he volunteered to pay). I just started to cut some additional firewood for our Southern MS winter needs and discovered that the Chain is not getting any lubrication. Upon further detailed troubleshooting/investigation, I discovered all my Chain Lube Oil was coming out the front of my Stihl. (Lots of oil) As most of you longtime Stihl Owners know, Stihl is "Stingy" with the Maintenance info they make available! I have attached a pic of the hole where the Chain Lube is pouring out of.
I said all the above to ask this; "Can anyone please advise if there is something supposed to be in this hole? and if so, can you tell me what the part # is?"
Very Respectfully,
The NEW Newbie
P.S. First thing I did was REPLACE the Oil Pump Assembly & all Hoses--Still Leaks out same Hole, shown in attached Photo.

Thanks for the prompt reply Mark!
I have already performed all the items listed on page 9---All NEW---Chain Lube is still being pumped out the front of the SAW, from the hole shown in the attached photo.
Does something belong in that hole?

Well Mark has sen you the service manual, I shall attempt to do the parts book.
There does not seem to be anything listed for that hole.
It could be a machining hole used to make the hole for the elbow and if that is the case a blanking plug should be in there.
However the seal between the pump & the elbow should be oil tight as should be the joint between it and the outlet to the bar.

Please only read the the document on your computer as you can see it is not allowed to be printed and the Stilh fairy will pot a spell on your saw & it will for ever more run backwards.

I would say there is suppose to be a ball bearing pressed in that hole, and it came out. May not be a separate part. You may have to find something that fits.

Thanks!....I think they already put a SPELL on my SAW.......I should have kept my HUSKY.....I just got tired of hearing all my Southern Stihl owner Friends telling me I should "GIT a REAL SAW".
Maybe one of them will let me look at his STIHL. Hopefully I can see if there's really something missing where the HOLE is.....?

One of my Buddies sent a photo of his MS-310....See attached......Do you know if there is a STIHL Part # for this?
This ORANGE THINGY is missing off my Stihl; and all my Chain Lube is being pumped out this hole!

I don't believe it does. I think it is a one-way, duck bill valve that is press fitted into the case. You may be able to match one up and fit it in. They are used in a lot of gas caps on 2 cycle equipment. I will look though all the IPL's I have for Stihl, but don't believe I have seen that as an individual part.

I lied, not a vent, but rather a plug.
Try: To replace you can use a grub screw, part number 9134 381 1230. On installation use Red Loctite 262 on the threads. Leave approx 1.5mm of the head of the screw exposed above the surface of the housing.

I'm not sure i can contribute anything more than you've already read in the previous posts.
I would like to add that as Stihl owner for over 10 years, I am very happy with Stihl Chainsaws. However, I disagree with your southern buddies saying that only a Sthl is a "Real" chainsaw. Husqvarna makes some fantastic saws. If you look at professional logging and guys whom run Tree Service companies, it's almost a tie between Stihl and Husky. It's honestly 50/50.
As I've posted in other threads, both saws have their strengths and weaknesses. To boil it down to very quick one liners, Stihl tends to have more broadband torque and power to get through the toughest wood. Husky tends to have a higher revving saw with the advantage of quicker cutting that is especially handy for that final cut when felling a tree and getting out of the way. Those higher revs potentially cause early wear on bars, chains and motors. Stih's lower revs potentially cut productivity if you are trying to get through a lot of wood quickly. There are other things to consider, but my opinion? Flip a coin. Husy heads, Stihl tail and buy either.
Since you HAVE a Stihl, go with it. It's a GREAT saw. If you really and truly want a Husky, fix that Stihl, sell it and buy yourself a Husky. With EITHER saw, you will have a great saw.
The point of my post is that I don't think you are jinxed. Any saw can give you a headache. I've heard some of the big box store model Huskies (Like you find at Lowes) have been a problem for owners. Some won't buy Husky because they sell to Mass Merch. Others won't buy Stihl because you can only get them through Dealers. But...You just never know. Go with what you want and be content. One advantage to me is my Stihl dealer. He's fantastic. There is no Husky dealer near me and I'm sure not taking to to Lowes for repair. I actually do most of my repairs too, but it's nice to have a dealer that I can trust just in case.
Keep us posted on that repair. We may have the same problem some day and your report may help us.

I'm in nearly total agreement with you.....and I do appreciate each and every response to my "PLEA" for HELP!
Really am reluctant to put a self tapping screw in that HOLE. I'd prefer to discover exactly what is supposed to be in that HOLE; and put the correct part back in it.
The same Dealer that performed my "Servicing" also offered to plug that HOLE with a SCREW......I'm hoping for a MIRACLE DISCOVERY of the correct "ORANGE THINGY".
Although, I really do know how to "RIG"; I'd prefer not to. I will have to break out the OLD Husky if I don't get an answer pretty quick......Gotta keep the BOSS WARM.....

Generally if it is not shown on the perts break up then it is not a service removable part and that usually means a supposed perminant blanking plug.

Sorry really late to the party, if you have not already replaced it do not get the orange plug, those will pop out over time and pressure.
You want the metal cone shape screw "which you can get at the Stihl Dealer", it will cut its own threads right in there and you do not have to worry about it coming out again unless the case cracks and allows it do. I have added them to three saws for different people myself and once they are there, they are there.
