Thanks Steve I really appreciate the info
I'm afraid there's more to the story about oil drain valves for your Arrow. But there's good news too!
The FAA issued airworthiness directive 81-11-02 R2 that mandated that placards saying, "Unapproved Oil Drain Valves Can Cause Inadvertent Draining When the Gear is Retracted - Use Only Piper Approved Part" be placed one on each side, on the lower engine mount beneath the intake and exhaust tubes. The AD mandates that Piper drain valve part number 492-172V be installed. Unfortunately, this valve lists for over $1800 from Piper.
It sounds like you have the valve but don't have the fitting that opens the valve to drain the oil that will work on your airplane.
There's a picture of the correct valve here: www.ebay.com/itm/New-Piper-low-profile-o...series-/162083244049
I spoke with Ryan at Saf Air ( www.saf-air.com ) He asked that you call him and said they have a new low profile valve that may work for you. Ryan's number is (734) 522-8360..
There are two systems. The pitot system is very simple--there's a hose from the forward side of the pitot mast to the back of the airspeed gauge.
This system rarely leaks.
The static system is most likely where your leak is.
The static system originates from a hole in the aft edge of the pitot mast.
Both the static and the pitot pressures are routed inboard to the wing root, then forward along the wing root to flexible hoses that transition between the wing and tubing in the pilot's side fuselage sidewall. Then up to the airspeed instrument.
The pitot (airspeed) tubing ends at that gauge. The static pressure is also routed to the vertical speed instrument (VSI) and the altimeter through "T" fittings on the back of each instrument then on to the airspeed gauge.
In addition to all the "T" fittings, there may also be a leak in the case of the VSI, altimeter, and A/S instruments.
There's no easy way to determine where the leak occurs. I would first look behind the panel to see that all the connections seem secure, and that any rubber tubing, if used if still flexible. I would also look at the tubing in the wing root to see if it has deteriorated.
One way to determine the source of the leak is to split the system in half; in other words, test the first half for leaks by disconnecting it from the second half and plugging the connection between the two halves. If there is no leakage in the first half, then the leak has to be in the second half.
There's no easy way, I'm afraid. This is one system that has many options for leaks.

It's on the way, it looks like it might do the trick. Thanks!!
There are no pins like on the top cowling.
The bottom cowling half is held to the airframe with 11 screws.
Remove the screws, supporting the cowling as you go, and then you can remove it.
You should have a screwdriver handy because you may have to loosen a clamp that holds a length of orange blast tube to the cowling. Just loosen the clamp and slide the tube off the nozzle fitting.
It does take a little maneuvering to prevent the lower cowling from getting hung up on one of the nose gear parts and the muffler down tube, but it's easy to do if you pay attention.
When re installing it, I like to use small awls or punches to put through the holes in the lower cowling into the correct screw holes to "hold" it in position before I begin installing the screws.
I also wait to finally tighten all the screws until all the screws are started in the nut plates that they screw in to.
After finishing, take one more look to see that all is right.
This change is pretty common. Piper installed rams horn yokes in later airplanes. You may be able to install one of those in your airplane; it will depend on the whether the length of the shaft attached to the old and new yokes is the same. One other factor that comes into play is the diameter of the shaft.
As you can see from the parts posted on this site: www.texasairsalvage.com/Airframe_list.ph...Control-Yokes&goto=1 the newer style yokes are readily available.
Here's another source: www.flyingfishaircraftparts.com/products...es-1-5-8-shaft-20575 .
They are even available on eBay: www.ebay.com/sch/i.html?_nkw=piper%20control%20yoke .
If you would be satisfied with a simple press to talk switch that attaches (via velcro) to you existing "bow tie" yoke, they too are readily available. I have one of the simple velcro style PTT switches in my Comanche and it's provided good service for over 10 years.
You can purchase a new rams horn yoke from Avion at:http://www.avion.com/PiperControlWheels.html.
Finally, I believe you can replace your "bow tie" yokes with rams horn yokes which were installed in the PA 32 beginning in 1970. That would be the easiest as far as paper work.
Looking for advice on how to remove the bottom cowling on an Archer II. I see the screws on the both sides towards the back. If I remove those, are there pins in the front similar to the way the top cowling is fasten? Thanks

Center Vent Duct P.N. H76307-07 overhead airduct, used in good condition taken out of a Piper Archer PA28-181, ($60. plus shipping).
We have encountered a leak in our system and was wondering if anyone has done a replace/repair of the line from the panel to the pitot tube? Any hints.
Reference first post I’m new to this forum, not sure what blue and red icon I must have inadvertently selected, I hope that’s why there’s no reply to my question. I would think with all the Piper folks here someone surely would have changed old style yokes out for newer versions.
I'll look into it for you.
Does anyone know of a company that manufactures and sells pleated cabin window shades for a 1979 Piper Lance?

I’m new here I have a 1965 PA32/260 and would liftoffs upgrade yokes to newer ram horn style with mic switch. Any suggestions on the change out and where to purchase along with any paper work required
Would this work?
The best I can do is give you some names out of the Aviation Electronics Association (AEA) Pilots Guide.
It lists: 1) Aero Industries ( www.aeroind.com ) at KRIC0; Bay Avionics ( www.bayavioinicsltd.net ) at KPVG) and Heart of Virginia Aviation (flyhova.com) in Ashland (KOFP).
There are other listings in Leesburg, Manassas, Lynchburg, Winchester, Midland, and Salem.
Let me know if you want more.
