Hello i have a 93 Cherokee 4.0 lots of miles still runs good but has developed a leak and it looks like the front main seal(crank seal).. have done the rear seal 2 years ago.. but what do i need to do and what is the part number or specific part name.. is it a "hard" fix? worse than the rear main seal?

all help is greatly appreciatted!!!!

 

geez anyone?

 

use lucas oil stop leak stuff. its way better than replaceing that stuff.

 

I mean how well does somthing like that accually work.. Ive read that it accualy expands the seal but breaks it down causeing worse failure down the road

 

it stopped mine. and its way easier to pour instead of wrench. so if it stops it for any decent amount of time i feel like its totally worth it.

 

how bad is the leak? on my 89 xj with 180k miles it looked like it had a leak in the front, and it ended up being that the harmonic balancer slid into the timing cover, and put a nice grove in it, causing a pretty good leak, but i only found that out when i tore the front end apart to replace the timing chain...

 

haha i see your point!
