strange noise and oil leak

Recommended Posts

99 24 valve, going uphill anywhere from 1500 rpms up, dosent matter what speed, im getting a strange whining noise. coming from the drivers side of the engine. any ideas? its not the turbo im pretty sure. also i have an oil leak coming from the bottom of the tranny bell housing, right on the edge of the cover for the flywheel and the torque converter. are the 2 related? havent noticed a loss in power, anything

Rear main seal leaking maybe. Tranny whining. Are you sure it is oil and not tranny fluid?

I would have to stick with the rear main seal leaking. Is the whining a new  noise?  Next time you pull that hill and it starts whining left of the throttle and see if it stops. If it does you are hearing the turbo spool.

Someone just last week had one of the intake cover bolts lose leaking air making noise but he had lower boost and more smoke, still worth pressure checking system for leaks. Could it be a belt making noise? Or possibly a bearing going out on one of the pulleys, noises can travel through things too and make it look like something it's not. 

I personally don't think problems are related, unless vacume plump seal is leaking, then maybe.

I am with DieselFuture check the vacuum pump, lay underneath while idling in park, if vacuum pump seal it's against the power steering pump and that could be whining. Usually will start to leak while idling, mine started under load though on a 2 hour trip then started getting worse until it leaked all the time when running. Steady drips while idling.

so i found out it only leaks at idle. vaccume pump is dry not a drip. im thinking just oil pan gasket. still unsure about whining noise. pretty sure its not turbo as i havent lost any power

 How about your tappett cover. They can leak and oil will show up all over from the air blowing around under the hood. My rear main is leaking, comes out right where the bell housing meets the tranny. Only place it can come out. 

 I just resealed my vacuum pump, never heard it whine. Not saying it isn't possible.

Post a picture of where the leak is coming from, may need to resize it so it uploads.

And you can post a video on YouTube and put a link here for noise issue.

its coming down right off that cover. but it is not coming off the bell housing so its not a rear main. and i can try to get a video but it will be hard to hear because its so loud in the cab bc of stacks

I had that leak, my oil pan gasket was flat from being tightened too many times. I had oil everywhere from the wind pushing it. If you need any pointers on the oil pan gasket let me know. It wasn't a bad job, oil pan gasket can be done with motor in the truck easy enough.

 

If you need to do any other work, like on trans, it would be a good reason to yank it. With that said, I would assume you can maybe do the rear main with the transmission pulled, can someone verify?

You have to pull the TC and flex plate.

I would love pointers on how to fix oil pan gasket leaking. My front cover, tappet cover, and oil pan leak. Brand new rear main seal 1000 miles on it or so. If I get the oil pan gasket to stop leaking I might get an itch and want to fix the other 2 leaks aswell. ALSO, What can I do with the front case vent to stop it from dripping on front axle?

Here is my oil pan story: Just did this about a month ago. I bought the gasket at Napa, make sure you get a one piece to make it easy. I highly recommend Permatex Right Stuff. I’ve used it on over a dozen oil pans and pretty much everything that needs sealed except fuel. Loosen the motor mount bolts, don’t remove them. The top of mount on frame is angled so it will lift. I chained a cherry picker to the motor with the lift eye at top of motor and one on the motor mount on the opposite side. Use something to protect the fuel injection lines. I also removed the starter to make room to use chain on motor mount, I wrapped chain and used hook on the mount that bolts to the motor. Unbolt the fan from the fan clutch so you don’t break the fan shroud. Lift the motor with picker, make sure the mounts move, the first couple times I lifted the whole truck and the motor never budged. I used a bottle jack to lift on the passenger motor mount then with picker down and got that mount to move, then the picker lifted it. I lifted until the motor hit the firewall, my air box lifted free so if yours is tight you might want to remove the hose from the filter to the turbo input. Then I still didn’t have enough clearance, due to the oil pickup tube, so I put a small bottle jack between the steering brace and the bottom passenger corner of motor right beside the oil pan. There is an exposed flat there beside the pan corner. Lifting there lifted just the front of the motor and gave me tons of room to get the pan out. Clean, new pickup tube gasket ( torque to correct specs) and then I put a thin layer of right stuff on the bottom of motor, this held the new gasket in place and makes it much easier. Then I put up pan and hand tightened bolts, let it sit for 30 mins to setup and then I torqued to spec all pan bolts.
