Alright so before I get yelled at again I hope this is a descriptive enough thread title. I also searched and could find what I was looking for so im starting a new thread. Anyways I took my truck in 2 weeks ago cause I had an oil leak. Well my mechanic put in a new crank seal. Well that seemed to do the trick untill today I noticed oil under my truck again. Sure enough I get under my truck and it looks like the oil is coming from the harmonic balancer dripping to the crossmember that runs under the motor and then hitting the ground. So does the harmonic balancer have anything to do with the oil leak or did the mechanic not put the crank seal in right.

 

5.2 or 5.9 engine? I hate to assume, but since you don't mention it and did mention the balancer I am gonna go with you have a 5.9 . Sounds like either the crank seal went bad or was not installed properly. But check to make sure its not a leak from some other place dripping down.

 

i would say he put it in wrong

 

5.9 or 5.2 both have same type of seal behind HB. And if i remember correctly i think part of it slides into seal. so either he put seal in wrong or didnt clean any rough spots or crud off HB before putting back together.

 

It's possible that there is a grove worn in the harmonic balancer and it needs a wear sleeve on it.

 

Plus on the repair sleeve.If he didn't put one on the HB it will still leak.Can you tell if it slowed the leak down any?

 

Yeah sorry I forgot to mention it is a 5.9. Im pretty sure the leak isnt dripping from above anywere. Atleast there was nothing that I saw. And It took 2 weeks before it started leaking again but now its constant. If it was installed wrong would it have started leaking right away? But I called the shop today and they told me to bring it back in on friday.

 

+2 on the speedy sleeve

 

5.2's dont have HB's since their internally balanced right?


and its possible the seal was put in wrong, and the pressurse/motion finally blew it out....maybe?

 

5.2 dont have HB? Since when cuz mine has a big *** thing on the front of crank that surely resembles one.
