OIl leak in 2001 Grand Cherokee Laredo

My 2001 GC Laredo is leaking oil, it has smoke and burned oil smell. Most likely the valve cover gasket or rear seal. What is involved in the repair of each and a ballpark estimate of repair cost.

    oil appears to be leaking from a steel plate or cap which is bolted to top of the left (passenger side) valve cover, toward rear of the valve cover...intermittently blows big clouds of foul oil-smelling smoke...but does not seem to be losing much oil according to dipstick...however, can't seem to keep water in radiator so could be oil in water... is this something a can of sodium silicate block seal could fix? or do I need to spend a couple grand on this van which I only paid $400 for, and replace the: head gasket? valve cover gasket? or rear main seal? or all of the above?

Valve cover gasket is like $20 and a do it yourself job, just buy a manual like a chiltons from an auto parts store. if it was valve cover, the smoke would be coming from engine, not tailpipe.

rear seal is in between engine and tranny, this would cause oil to leak on ground, but not to burn

if smoke is coming from tailpipe, your piston rings might be going bad. that is an expensive repair, but switching to synthetic oil may give you several more years of life out of the piston rings, synthetic oil has a way of soaking into bad piston rings and temporarily making them like new again, unless they are already too far gone.

Smoke comin from top rocker cover smell like burnin oil


Could the smoke be coming from the exhaust manifold on the passenger side of the engine? When the valve cover starts to leak, it is common for the oil to leak down and burn on the outside of the exhaust manifold.
Replacing a valve cover gasket is not difficult or expensive, and it is common for BMW valve cover gaskets to get brittle and shrink and start leaking every 10 years or so. My wife's 330 needed a new valve cover gasket at 6 years.

I havea daewoo nubira and we replaced the valve cover gasket yesterday , did an oik change and now the engine is smoking white smoke. Try to check to hoses, could not see a leak. Where is the cylinder...


Hello and welcome to FixYa!

The cylinder head is located on the center of the engine. Yes it can be a worn out head gasket or piston rings. If the piston rings are worn out the oil is burnt that's why it emits white smoke. You will need to replace the head gasket and piston rings.

Hope this helps and thank you for using FixYa! Have a good one!

Oil smell smells like it is burning oil last oil change was 3 months ago


Common causes of smelling "burning" oil are:
  1. a leak in the valve cover gasket. When oil leaks from the valve cover gasket, it will often burn off on the manifold.
  2. a blown oil seal causing oil to burn off on the exhaust system
  3. check your exhaust for "blue smoke" a sign that the engine is actually burning oil. Just guessing here but a 16 year old Volvo is bound to have quite a few miles on it.
I hope you found this post helpful in diagnosing your problem. Thank you for using Fixya! Greg

Burning smell and smoke coming from hood


you may have an oil leak and the oil is burning off of the hot exhaust or engine youll have to open the hood in order to decipher where the oil is coming from. or if its even oil it could be transmission fluid coolant a number of things youll have to see if you can tell exactly what it is thats leaking but my best guess is its probably oil.if it is oil its more than likely coming from the valve cover. id check there first.

My engine is smoking and smells like burnt oil? maybe. there is a gear symbol with an ! next to my park/drive on the dash board


Perhaps oil has leaked onto the exhaust manifold.
Check the oil pressure also.

Oil LeakOil leak, probably valve cover gaskets need replacing or just tightening. Also if it started suddenly after an oil change, the filter may be leaking, or you spilled oil on the manifold.
This MY & others had problems with both the cranshaft oil seal. The rear one leaks onto the exhaust and can make a horrible burning oil smell, notably when you stop after a long drive.
Head Gasket
Outbacks up to 2001 have issues with head gaskets, its a widespread problem. If the smoke is white and smells sweet it is coolant leaking into the pistons via a head gasket. Replace the head gasket before it fails. If you blow the head gasket it will ruin the engine.
Cam Seals
It is most likely the cam seals dripping small amounts of oil onto to the bottom of the engine block. When the engine warms up, it will burn the oil off.

Oil smell in my vw


Sounds like valve cover gaskets need to be changed - they're a common failure on the 30v engine. Fortunately, they're also relatively inexpensive ($25 per cylinder bank - you need two - from www.ecstuning.com). They're also easy to change. They'd easily explain your oil smell - oil leaks onto hot valve covers and burns. Also, the misfire could be (not a guarantee, but it's possible) a result of valve cover gaskets as well - there's the main gasket which seals around the edge of the valve cover, and a second gasket shaped like three rings. This trims and seals the openings around each of the spark plugs, where the plugs are inserted through the valve covers. If you're leaking there, you can drown the top end of the plug in oil. If that gets into the spark wire boot, it can cause a misfire.
