I have a 1999 Chrysler 300m 3.5 that is leaking oil. There is no obvious source from the engine, though it is possible. The car overheated last year and I had the dealer replace water pump and timing...


CK- Try a set of Valve Cover Gaskets. It cannot leak from the front cover area because it is where the timing belt rides and there is no entrance into the engine EXCEPT the front CAM SEAL... Remove the cover and look toward that seal behind the cam sprocket. If so it is also leaking down into the front cover and beyond. But look at the Valve cover gasket first, since you mention that source.

Can my 91 toyota carolla leak oil if the bolts on the timing belt cover are all missing.


Thats a very good question, a timing belt is a dry belt. What that means is no oil should be in the general area. You have a couple of seals your camshaft oil seal and your crankshaft front oil seal. As long as both of those are not leaking then you will not leak oil in that general area.

1995 toyota camry leaking oil from behind the timing belt cover. Isn't this a major repair? Is the leak more than likely a camshaft seal?


If you haven't had the timing belt replace (60,000 miles is the suggested service intervale) this is an overlap of having the timing belt replaced.
If the timing belt is not due for replacement and its the cam shaft seal that is leaking. Its a pretty easy fix. Remove the top timing belt cover , and the crankshaft sensor wiring you may have to remove the front engine mount . Set #1 piston at TDC, Loosen tensioner w/ spring slip off belt. **Remove sprocket pull out old seal with a sharp pick. Greese and install new seal make sure its flush with its bore . Reistall sprocket. Slide belt over Cam sprocket tighten tensioner. Install cover and mount (if applicable) Check timing marks by turning crank two revolutions.
** If CamSprocket Bolt is difficult to remove then remove valve cover and use a 21mm wrench to hold the Camshaft while you crack off Cam Sprocket Bolt.
You will see the groves on the Camshaft where you can place a wrench to hold the shaft.
After you replaced the seal replace the valve cover gasket ONLY IF YOU HAD TO REMOVE THE COVER TO HOLD THE CAM WHILE REMOVING ITS BOLT.

This is about as major as it gets.

2002 Chrysler Sebring LTD Convertible, Mileage 58,300. Oil leak


That's a lot of work considering the low mileage on your car. Makes me suspect that you are taking it to the Dealership for service. if so , please be aware that dealerships are the most expensive place to have your car serviced and often do unnecessary work. If your warranty is over , find a trustworthy mechanic and tackle things one at a time. First ask him to determine where the oil is leaking from and repair it. Need more info about the trans "slip" before i sugest any action , could be several different minor problems. Good Luck.

1999 cross country v70 awd crankshaft seal replacement


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.
