A leaking front seal will allow oil to get into the area where the timing belt is located. This will cause oil to get on the belt and can cause damage. Since the timing cover must be removed to access the front seal, it is recommended to replace the belt while you are in there. Also, the water pump is driven off the timing belt. Replacement of the water pump is always recommended when replacing the timing belt for two reasons. First, it is easily replaced at this time and it is good preventive maintenance. Secondly, the water pump bearing is under tension from the timing belt and develops a wear pattern. Replacement of the belt without replacing the pump will cause the new belt to wear the bearing in a different pattern, often causing leaking in a very short time after the replacement. This would then result in having to repeat all the labor again to replace the pump. It is easy to see that for $400.00 labor, you don't want to do that again in only 2-3 months. as far as the VTEC valve is concerned, I don't see a relationship to the oil leak. It could just be something else the mechanic found during the inspection. I can find nothing in the remove/replace procedures that requires replacement of the oil pan gasket. Again, maybe something additional that is needed from visual inspection, but not needed for the front seal.
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.
severe oil leaks would be front timing cover crankshaft seal and the rear main seal or leak at oil pump at front timing cover oil leaks can come from damaged oil filter seal or damaged oil pressure sending unit.slow oil leaks oil pan gasket the valve cover gasket leaks you will see and smell smoke from under engine compartment which could be a fire hazard.
There can be alot of causes, such as valve covers leaking, oil pan gasket leaking, oil filter leaking, rear main seal leaking, front timing chain cover seal or gasket leaking even bad rings. Does it smoke out of the back? Your valve seals could be leaking. Best way to find out if you have a leak is to inspect the valve covers manually, or take newspapers and lay them under the entire engine on the ground, and it will leave the tell tale stain of a leak. Hope this helps.
The most common cause of all oil leaks is the valve cover gasket.The oil drips down from there and covers everything.If your valve cover is leaking, replace it first.
Then the second most common leak in the front of the engine is the crankshaft seal.This seal should have been replaced when the timing belt is replaced as you have everything removed to get to it, and the seal is easy to replace.However if it is not replaced at that time then you will have to remove everything again to access it.The seal is 3 or four dollars, but the labor is two to three hours and you should replace the timing belt, idler pulleys, tensioner and water pump when you are in there, as that will all be removed.Hope this help.Good luck :O)
This is the same as a Toyota Corolla. Plan on replacing the timing belt and all associated parts. The problem is either the Camshaft or Crankshaft seals. Timing cover seal does NOT keep oil in the engine. The oil getting on the timing belt WILL cause premature failure.
- cam cover gaskets (rear one drips on the exhaust)
- camshaft end seals
- distributor shaft o-ring (appears on top of transaxle housing)
- oil filter bracket to block o-ring seal (drips on front bank exhaust)
- crankshaft nose oil seal (have done with timing belt change)
- rear main seal (expensive, leave it be)
hi if your engine 22R front engine first in side timing cover where engine bully fitted there is oil seal, next valve cover front side between cover and head there seal not like oil seal half cercle shap it makes leak also front side of the camshaft there is oil seal..
