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.

1992 Ford Crown Victoria Oil Pan is leaking. Is this a major problem to replace? Fred


It is recommended that you lift out the engine before attempting to replace the oil pan. Once the engine is lifted you can remove the bolts, remove the pan, clean all the old gasket material.
Installation: Remove the rear main bearing cap oil seal Remove the timing cover oil seal Clean all the mating surfaces and seal grooves Install new oil pan front cover seals Install a new rear main bearing cap oil seal Install new oil pan side gaskets on the block Make sure the tabs of the front and rear seal fit properly as these are critical spots Attach the oil pan to the engine block and install the retaining bolts

Have oil leak not heavy, but it leaks any answer were it could be coming from..


Valve Covers, Head Gaskets, Oil Pan Seal and a number of other spots. You'll need to clean the motor with Gunk Engine cleaner and then look for the largest build ups of oil and crud to get a better idea where it is.

How do you replace a gasket and cover for timing chain and rear seal gasket for oil pan on a 1978 Chevy 350 motor


the oil pan will need to be removed to repalce the rear seal, so replace the front seal and gasket then, replace the timing chain/gears if sloppy, then reinstall the oil pan.

Change front main seal , leaking oil around timing chain cover. could be seal around harmonica balancer.


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.
