Need to know which oil plug to pull on a 2007 ultra to change engine oil im guessing its the one to the extreme left front

That was not the drain plug you pulled. Here is where i learned alot about my bike great source for information. And dyi guides. Idk when this was posted but you want to go here before you get into alot more of a project.

Rondy being Rendezvous LOL? Engine capacity is listed as 1 gal - 4 quarts.

On your Ultra, the oil pan is on the bottom of the transmission. If you pull the oil dipstick, you'll see that it goes down into the pan located under the transmission. The engine oil drain is the drain plug nearest the left front of the pan or in the middle of the pan. If the bike is on the side stand when your drain the oil, I'd pull the plug in the front so that all the oil comes out. If you pull the one in the middle, you must stand the bike up straight to get all the oil out. The transmission drain appears to be the pipe plug in the front of the oil pan. Go to www.bikebandit.com and pull up this drawing. It will show you the pan and the gasket. Notice the gasket closely, the hole down through the front of the pan looks like it goes to the transmission and the other plugs look like they are for engine oil. The plug you pulled out is the drain for the cam chest, I think. I'm not a Twin Cam mechanic but I'm pretty sure that I'm right about that particular plug. You probably didn't get any more than a couple of ounces of oil out of that area.

The oil tank is on the bottom of the transmission. The engine oil drain plug is on the left front corner of the oil tank. Drain the oil, change the oil filter, and refill with three quarts of any approved 20W50 weight engine oil. Check the oil level using the dip stick. The dip stick is located on the right side of the transmission. The oil cap is a large cap (2" or 50mm in diameter) with knurled edges on it. The dipstich has two marks on it. The top mark is 'FULL HOT" and the lower mark is "FULL COLD". Keep the oil level between these two marks. Check the oil level with the bike on the side stand.

Good Luck

The oil pan is on the bottom of the transmission. Look under the transmission and you'll see two drain plugs. The one closest to the front left corner is the engine oil drain. The one closest to the center is the transmission drain.

The oil tank is on the bottom of the transmission. There are two drain plugs. The drain located about the center of the oil pan is the transmission drain plug. The drain plug nearest the front left of the oil pan is the engine oil drain.

A rich smell to the exhaust fumes when the engine is cold is typical. The computer on your bike (and your car) senses that the engine is cold and requires a slightly rich mixture to run. When the engine warms up, the computer leans the mixture back out. This is why you don't have a "choke" on your bike, the computer changes the injector dwell time to richen the mixture instead of you having to use a choke.

The oil tank is on the bottom of the transmission. There are two drain plugs, one for the engine oil and one for transmission lube. The engine oil drain is the one closest to the left front of the oil tank. The drain that is more in the center is the transmission drain.

I'm guessing it could be your front engine seal...

the 2007 avalon has a cannister oil filter loof under the passenger front of the car youl see the oil pan and drain plug its just in front of the oil pan towards the front of the car its metal casing with a small square in the center thats where youl need a 3/8 exstension and ratchet to loosin the cap to change the gasket for the cap when you get your oil filter it comes with a small plastic piece so you can drain the oil out of the oil filter case, to change the oil filter itself you need a toyota specific oil filter tool to loosin(can get at any toyota dealer run about 20 bucks) take the filter out change the gasket around the case and thats it hope this helps

should be on the front left of the oil pan.
ye second one on the bottom right is transmission oil.
