I have a 1998 nissan losing oil can smell it inside car looks likeit might be leaking from vavle gasket turn engine on and is smoking by the exhaust manifold however back side of cover clean front side lots of oil along it also on left side of egine lots of oil on a small canister with hose going to it thanks
You need to find out just were the oil is leaking from to start with .I have just done my Mercedes with the same problem valve cover gasket was leaking .Oil was leaking down the side and on the plugs that are hot ,, so it burns off the oil ,this is what you can smell. If other items are doing the same you will need to do that part as well..The breather system may be blocked up also if it is not breathing oil will build up . Good luck

CV joint has gotten debris and moisture inside. The CV boot is bad and not protecting the joint. Now its metal on metal grinding. This happens when turning as there is more pressure on the joint. Please fix this ASAP as it can be dangerous to drive on a bad CV joint. While I have seen people drive with a bad CV joint for over 4k miles, it is NOT recommended!

Back to what I said before, only perhaps it didn't get really hot. Only two major causes of oil burning. 1. rings and cylinder walls are worn or 2. bearings are a bit out of clearance and throwing more oil on the cylinder walls than the oil rings can deal with. Other reason should have been taken care of when head was done: valve guides & seals. You can still read good compression with certain conditions. a more accurate test is a cylinder leakdown test. On another idea, if one cylinder was being washed down by coolant, it may have unseated the rings. sometimes they recover from this, sometimes not (likely in the cylinder with warped valves. Check that plug for oil fouling...could be where miss is.

replace the front oil seal. first i would clean the engine with purple power (degrease etc.) then look at the engine and make sure the leak is not coming from above like possibly the valve cover gasket or from the oil sending unit. try to tighten the bolts on the valve cover and even the oil pan. you never know, you may get lucky. i don't know where you are but front seals are cheap but the labor on the job is what costs you.

If you cant find the leak give the engine a good wash down , makes it easier to spot the leak.

When diagnosing a water leak, here's a handy tip. Check the accumulated water. If the water is dirty, look for leaks from the underside of the vehicle (floor, wheelwells, etc). If the accumulated water is clean, look for leaks from the topside of the vehicle (trunk seal, window seal, etc). To find where the water is coming from, shut yourself in the trunk with a flashlight and have an assistant run water over the trunk with a garden hose. You may have to remove some of the interior trunk trim to see exactly were the water is coming from, but chances are you'll find it. Also another common cause of water leaks are from impact damage, so check for collision damage repair. while your in there. -hope this helps.
