oil leak

I have had this oil leaked and today I think I narrowed it down to this T bolt above the oil cooler. Does anyone know what the oil cooler is connected to and what the T bolt is?

Hoping for some feedback. Bought my daughter a regal and noticed a small oil leak on the ground. After I got it up on ramps I noticed the oil level sensor was one of the areas it was coming from. I have read over other posts on this site and have gathered a lot of information. One thing I...

My parents gave my 17-year-old son their old 2010 Buick Lacrosse CXL AWD 3.0L with 83,000 miles on it. There is a small leak between the engine and transmission. A mechanic suspects it's the rear main seal and quoted $4,300 to fix it, which we cannot afford (I am a disabled veteran). I...

2014 Buick Regal 2.0 turbo, 96k miles Hi all, I was hoping to get some feedback from anyone with knowledge on these 3 codes or turbo replacements in general. A few days ago my car started having issues and check engine light came on along with "reduced engine power" warning. I plugged my...

Rat droppings found on engine, 05 LeSabre started sputtering and vibrating while driving then it stalled. Most likely engine is misfiring (unsure which cylinder because I don't have my scan tool on me atm) since the CEL was blinking. Engine turns over fine, but won't stay running. Also noticed...

I noticed some oil building up on top of my engine, so I cleaned it up to get an idea of where the leak is coming from. I looks like its coming from a hose going into the engine. Does anyone know what this hose is for and what is wrong? There are 3 pictures attached: (1) oil buildup before...

Hey all, I have a 2015 GS and a last year I started to smell oil burning and would see smoke coming out around my passenger head light anytime it would rain or snow. Especially if the heat was on. After looking under my car I noticed that oil was all splattered on the underbody of the car. I...

Just purchased a 2012 Regal GS for my sons first car. Has 97k on it and noticed it has a slight oil leak on the passenger side near the drain plug area, but the oil seems to be all around this area on the rear of the cradle on this side. It only drips maybe a penny sized spot on the driveway...

I've got an '07 Buick Lucerne CXS with the Northstar V8, 87K miles. It's got a small leak around the oil pan, I think. (Hard to see up there) The leak is not so fast that it leaves a mess on the garage floor, but it does leak fast enough that the wind pushes the oil all over the back bottom of...

I just replaced the spark plugs on my 2007 Lucerne CXS. Took me about 8 hours. The front four were easy, probably less than an hour. To get at the back four you have to remove the secondary air injector, which is a bit awkward because it is ALL the way in the back of the engine. You'll need...

At the end of a recent drive I smelled burning oil. Unfortunately I was heading in from picking up meds for my pneumonia so I forgot. A week later still sick I ran out to see the doc and was quickly reminded. Oil is all over my alternator, trans cooler lines, and the entire right side of the...

I have a 1995 Buick Lesabre with just over 100,000 miles. I changed the oil and filter recently as I routinely do every 4-5,000 miles. After changing the oil I noticed a small oil leak which was dripping from the oil filter. I checked to make sure the oil filter was on properly installed and...
