Seeking advise - oil leak
Hello everyone,
I purchased a one owner 2005 ls430 with 144,000 on the clock. The TB was done at 88,000 miles. I recently noticed a oil leak and a burning oil smell. I took the ls to my mechanic and he says the crank seal is leaking and the valve cover gaskets need to be replaced. He wants to replace the TB when he makes the repairs on the seal and valve cover gaskets. My question is should the TB need to be replaced?
Thanks,

TB isn't scheduled to be replaced for until you hit 178K. If you are going to pay him to replace the crank seal it probably wouldn't cost you that much more to get the belt changed now. How much does he want extra to change the belt?
The burning oil smell is probably coming from the valve cover gaskets. You could simply take a socket and see if you can snug down the valve cover bolts to see if that stops the leak. Doesn't cost you anything to try...

Glad you handled the matter yourself and saved a ton of money. Have the crank seal replaced when the car is ready for it's next timing belt service.
Just a quick note- the valve cover bolts are rated at a VERY low torque of 53 in. lbf (yes that's INCH which converts to 4.4 ft.lbf). If you used a 3/8" drive ratchet you probably over torqued them. No need to run out and buy a small torque wrench that measures in.lbs but you might want to go back and double check. Over torqueing can crush the gasket making the leak more serious than before.

Yes, I saved a ton of money doing it myself and thanks for the help. I used a 3/8 ratchet I didn’t think to look up torge settings, Well now I plan to do the valve cover gaskets myself if they ever start leaking again.Wow, if you purchase the right tools for the job you can get the job done.
Thanks,
Thanks,
