Oil Ficker!!??

[bradseals]

hey everyone . I'm in a sort of predicament here . . I purchased a remanufactured engine recently and lately have been cleaning all the miscellaneous covers and putting this thing together but I think I'm in some trouble . . I was at one of the local shops today getting some torque specs from a friend and happened to notice a small oil "flicker" that appeared to go on the crankshaft in front of the small timing gear. . in a panic I asked the owner if he thinks my remanufactured engine had come with one already on it and he told me hes pretty sure that the one off of my original engine was supposed to be cleaned and reused on the new motor but I know I didn't take that off or know at all that I needed to . . .so my question is have any of you ever dealt with or purchase a remanufactured engine . and did yours come with one? how critical is this part? any help or advist would be appreciated because ive alreadt put my cover and oil pan with the new rubber gasket on ..  in the event that I have to pull the damn thing back apart would I be able to use my oil pan gasket again or should I take the hit and purchase another one?

:doh:  thank you all , brad

This "flicker" you're referring to is called an oil slinger.  Looks like this, right?

 

Yes, you clean and reuse your old one.  I did when I did my stroker for my XJ.  Installs like seen below:

 

 

As far as reusing your oil pan gasket, you should be fine to reuse it so long as you don't damage it removing the pan.  It's rubber and from the sounds of it, it hasn't been on there very long, so it's by no means unusable.

I don't think you have to remove the oil pan to install the flinger, just the timing chain cover. I would first pull the vibration dampener pulley and remove the oil seal to see if the flinger is in there or not. If it is there, put in a new oil seal, replace the pulley and you're good to go. If you can't see it, pull the timing chain cover, put the flinger on and re-install the cover with a new timing clover gasket set (you can probably re-use the old one).

Did the reman engine come with a new dampener pulley? If not, I would buy and install a new one while you have the engine apart.

If the remanufactured motor came with a new Mopar harmonic balancer the slinger is supposed to be omitted.

 

I don't quite get it, but when I ordered a balancer for my rebuild I was informed the part # was old and has been replaced with a new part # which was about double the price. The documentation with the new part # indicated the slinger needed to be omitted.

thankfully I haven't yet put the harmonic balancer (crankshaft pulley) but I did purchase a new one awhile back so thatll be okay . . I supposed ill have to replace my seal and cover gasket just to be safe because I DO NOT want to deal with replaceing all of that when I do put the engine in  . its 100x easier with it on the stand thanks for yalls input  . I just have to go about finding one of those damn oil slingers  :/

^^  This is 100% correct. The old Mopar balancer, p/n 33002920, requires the slinger installed. The newer Mopar balancers with an AB or AC suffix however are slightly thicker than the old balancer. So to seat all the way on the crank the slinger needs to be removed for the new Mopar balancers. However if you use an aftermarket balancer, like a Dorman or Pioneer, the slinger needs to be there as it's the same thickness as the original Mopar damper.

 

As far as the oil slinger being necessary or important for lubrication, it isn't. It's only necessary as a shim.
