Well you have a cost/benefit analysis to do. is it worth fixing the seal, given the age and condition of the car and the expense of getting to and replacing the seal? you are going to have to separate the engine from the transmission, remove the flywheel or ring gear to get at the seal. this may require removing the tranny on a RWD vehicle or perhaps pulling the whole engine/tranny out of a FWD car.

if it is worth fixing then buy a CD repair manual on eBay for about 10 bucks, get a buddy and some beer and set aside a weekend. rent an engine hoist.

aside from lucas additives which do not work anyway, there is no magic fix for this.

SOURCE: trans leak on a toyota pickup

No there is no internal oil seal in the tail housing.
Maybe you damaged the seal when refitting the tailshaft.. It is easy to do.. Did you grease the seal so the tailshaft wouldn't damage it upon reinsertion?

SOURCE: replaced rear main seals and oil pressure sending on a 2000 z71

Check the oil filter housing and the cooler lines at the housing. The oil filter housing gaskets are good for no more than 15k to 30k miles if your lucky. The lines at the housing are easy to strip out when you reinstall them so take your time if you do it yourself an once you are finished and ready to start the truck, let it run for about 15 minutes and constantly check the area for leaks prior to road testing the vehicle.

Oil leak front engine timing chan


1995 Tracker would have a timing BELT. Normal oil leak points (in order) on a Suzuki G16 engine are the distributor base (rear of motor), valve cover (top of motor), front main seal (behind lower timing belt cog) cam seal (behind the upper timing belt cog) and rear main seal. (behind the flywheel). I'd suspect the front main seal or cam seal. I use foot power to help find oil leaks.

How do I tell if my rear main seal is leaking in my 96 Buick regal


1. Are you losing oil? Have you been told this seal is leaking? This seal is located between the engine and transmission connection. This seal will be soaken wet with oil if failing. Your motor is probably the GM 3800 V-6...this motor is not known for excessive rear seal problems. Hope this helps.

Oil leaks under a 1997 super saloon automatic . leaks below bell housing


Could be a couple of possibilities that you'll have to get into looking for. Rear oil pan seal, rear main seal or occasionally rear intake seal will leak down back side of engine. Wipe down motor or spray w/brake clean and watch for leak.

Need a engine diagram for a 2.8 ltr v6 showing rear main seal


Just a little advise before you jump to thinking the rear main seal is leaking. The vast majority of the oil leaks from these 2.8L motors are the rear intake manifold seal and the distributor o-ring. I would check them first. The rear main seal is in the lower rear of the motor, you have to remove the transmission to replace ti.

Leaking tranny fluid by the torque converter is this my rear seal?


It is most likely the front seal on the Tranny, or a leaking tranny pan gasket.
The rear seal on the engine would leak motor oil

My ford transmission has no leaks that i can see but i have to put transmission fluid in once a week??????????????? it runs fine but where is the fluid going?


It could be the rear main seal on the transmission where it mates to the motor. The motor may be burning off the leaking fluid before you can spot the leak. It could also be leaking out of the shaft seal as well, but you should be able to see tranny fluid all over the underside of the back of your car. You should be able to see it if its leaking from the rear main too, but like I said the motor could be burning it off before you spot it.

How much tranny fluid per week are we talking about? The rear main seal would require you to pull the tranny and then you pop the seal in, not too hard of a job unless you have a transfer case. Doing it in your driveway is not feasable tho because a tranny weighs a lot and I do not think you want to balance it on your chest in your driveway.

1994 northstar motor leaking oil from engine block, where could it be coming from


Most likely it is the rear main seal. It is the seal that surrounds the crank shaft as it extends out to the transmission. The rreplacement of this seal involves removing the transmission. You could also have oil leaking from the rear side of the oil pan or the rear of the valve covers. But in most cases you can see this leakage. Therefore it is most likely going to be that rear seal.
