Dreaded Oil Leak

[RyanbabZ71]

 

Seems to have gotten worse now that it has been consistantly colder out. Looks like it will be going in next week

Is it the rear main seal or oil pan leaking? That's a lot of oil dripping.

[pm26]

When I had a rear main oil leak in my '95 Nissan pickup, there was a 6 inch diameter puddle of oil on the ground every time I parked the truck. He has only a few drips. But it can get worse.

Dont know havent been able to track it down previously. It was dripping on the floor and I would only see a drop like the middle pic once every few wks. The is only the second time I have seen any spots on the ground in the garage. Now that it has gotten cold it is leaking more. Oil level is still good . Tomorrow I plan on pulling the skid plate and taking a look.

At least from what I read on the board once these problems get fixed they tend to stay fixed. Good luck.

My 07 had a problem marking its territory, and went under the knife. We thought it was oil pan gasket at first then a week later it went back in to get the rear main seal replaced.

So Im standing in my shop next to my service advisors looking at my then brand new new body style truck, one of the first to get its guts ripped out in our shop. Im smiling, transfercase on the floor, tranny on stand, driveshafts and exhaust everywhere and a customer walks up to me and says " Boy Im glad thats not MY brand new Chevy, all its guts all over the place!"

I had to smile sheepishly and say, nope, its mine.

Good news, the replacement rear main worked as long as I had the truck. The tranny came out once more when the torque converter seal started to leak, after that Im pretty sure the guts stayed in that truck.

jeez way to paint a vivid picture Maybe I should put some duct tape on it???

Mine had a *very* slow seep at the oil pan gasket, and would eventually wet the bottom of the motor. That's a lot more oil than I had, but it could still be the pan gasket. Mine had sit for a while before I bought it, so I expected something like that could happen. I recall that you ordered yours?

[RyanbabZ71]

Yes mine was ordered.

 

Also after parking last night no oil on the floor. Needs to warm up so I can pull the skid plate off. No fun in 9 degree weather

[RyanbabZ71]

Not 100% sure but I think it may be from the oil cooler lines? Also there wasnt all that much oil on the inside of the skid plate.

[foghorn23]

The lines sure do look wet; maybe that's all it is. I had a leak early on with my truck (around 5000 miles). It turned out that mine was a power steering hose that was leaking. Sure made a mess, but I was mighty glad that was all it was. A new hose, a little simple green & the garden hose after the repair and all was good. Hope you get as lucky.

 

Reading Rolling's post above feels Halloweenish.... little too scary. Hope you don't have to go there.

Well after cleaning it on Saturday and taking a short trip Sunday morning, there were no leaks Sunday evening or this morning. After driving back and forth to work it had started to get on the skid plate again. I did some digging and found one of the lines under the hood wet (see photo). Have an appointment for Friday morning. We will see

Mine has had a slow leak on the oil filter side for the last couple of years, I have just been putting it off because

I hate to take it to the dealer for any work.

Took it in to dealer today & picked it up a few hours later. They replaced the oil pan gasket, filter & put in 6 new

quarts of oil. Only time will tell if that was where the leak was coming from.

Powertrain warranty expires in April of next year.

Well got the truck back. Issue was a bad oil cooler line. God I missed the 6.2 for a day, I had to drive the darn 5.3 Tahoe
