The Dodge Dealer is saying the crank seal and cam seal are leaking when they went to change the oil, are these transmission seals or engine seals? do I need to place them or is there a product that will help seal these-the vehicle has 99,000 miles.

Dear Sir,
Here is the oil leaking Problem Identifying Technique

Engine oil leaks from the valve cover gasket are common.

The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.

External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.

Engine oil leaks at the distributor can be misdiagnosed as leaks from theintake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.

If the oil filter casing shows signs of distortion from excessive oil pressure, theoil pump should be replaced.

Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.

Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

I think it helps to analyse u r Problem

Because there are also cam seals & valve cover gaskets which could leak. (Both at top part of engine( Usually if you hot steam clean engine--restart engine--watch closely & may see where oil starts to leak again.

This sounds like the crank seal, the engine doesnt have to be removed, in order to get to seal is like replacing the ttiming belt, and once in the timing belt i would replace the crank and cam seals, also do the timing belt, and maybe the waterpump, you will need to remove the crank pulley and then the timing covers then align timing marks for timing belt before ou remove it, with timing belt off the crank pulley then slides off the crankshaft and the seal is behind it, the cam shaft gear unbolts and the seal is behind the gear, once the gears are off then you will be able to remove the seals from the engine,heres a few diagrams to help. good luck and i hope this is helpful,

yes, I just changed one of these recently. Had to take both front and bottom off engine. Very difficult repair, as there are no good jack points for the engine when you have all the motor mounts off.
Here is procedure I would recommend.
Remove starter and engine to transmission brackets front and back.
Remove transmission starter gear cover.
drain oil and remove oil pan.
put a block under the crankshaft and jack to release weight on motor mount.
remove front motor mount (by serpentine belt)
remove belt.
remove compressor and bracket.
remove crank pulley and vib damper.
remove timing cover. mark timing belt with direction of travel
loosen tensioner gear.
remove timing belt.
remove crankshaft timing gear and key.
remove seal and oil pump housing.
clean gasket surfaces.
replace seal and reverse procedure.

If you have questions, let me know.

List of possible locations for engine oil leaks:

Valve cover gasket
can,crank and oil pump seals.
rear main seal
oil pan gasket
Transmission oil leaks
Vents, dipstick,torque converter ( need to examine shell to pin point whether its the oil pump or a converter seal)transmission gasket,axle seals, drain plug.

First have to determine where are you loosing it from.
Possible engine oil leak areas : Valve cover gasket,oil pan gasket, rear main,oil filter. crank or cam shaft seal, oil pump. Pcv valve.
If its transmission oil leaking here are a few areas of interest: shell of transmission( depending where on the shell could be oil pump, or converter., vents, and axle seals.
If your not capable to jack the vehicle up and look for the leak , then take it to a repair shop.
Keep me posted

maybe the leak is not in the cam or crank oil seals. i have the same car, found out the leak is coming from the valve cover and crank case (oilpan).

Yes it's a bad seal and most likely the side bearing to the trans axle is bad too. Once the bearing has play, it vibrates and causes the oil to leak though the seal. Note: if one side went bad the other side is soon to follow since they have the same amount of miles on them. Might as well change both side. Good luck and hope this helps. Keep an eye on the transmission fluid level, don't want to burn out the transmission.

Your info is confusing. The rear cam seal is not inside the timing belt cover, and the crank seal is at the bottom of the engine, while the cam seal is at the top.

Is there oil at the top, around the cam seal? Or just at the bottom? It's common for the oil pump seal to leak. If you get the oil pump reseal kit, it contains the oil pump seal and gasket, as well as the crankshaft seal. Make sure you seal the oil pump bolts, Volvo has special copper washers for this purpose.

Just try to locate the oil leak before replacing any more parts. Sometimes it can be something simple like the oil cap seal or the oil trap housing.

Had similar problem (Jetta 5 cylinder 2006) - leaks in the timing chain cover, large oil leak near the tranny (sounds like your problem), leak from "ALT belt side crank pulley seal and leak from oil pan. This car has only 23,000 kilometers about 14,000 miles on it!!! The dealer repaired this at no charge...
