Oil leak from harmonic balancer Chevrolet 350?

The oil leak is probably comming from the top of the oil pan there is a rubber gasket that goes between the oil pan and the water pumb which would make it look like its comming from the harmonic balancer, try replacing the oil pan gasket this should fix the problem. New answer: There is a small round oil seal / Harmonic balancer seal that fits in the timing cover and the balancer slides through the center of it. That is probley were your oil leak is. Most of the time the balancer itself gets a groove wore in it over time from that rubber seal running on it. You can repair the balancer by buying a Harmonic balancer repair sleeve/ speedy seal. Also replace the front timing cover seal.

How do you replace gasket seals at the timing chain area oil is leaking out in that area of my 1998 Nissan 200sx-se 16l?

If the oil is leaking from the timing chain cover behind the Harmonic Balancer (main large double pulley the belts run on). After removing the belts you need to remove the Harmonic Balancer using a puller, not to damage it, and then replace the seal in the cover. Inspect the back side of the Harmonic Balancer. The seal only seals to the shoulder of the Harmonic Balancer not the back face. If the shoulder's surface is not smooth replace it or it will leak again. Apply some light grease on the seal and mating surface of the Harmonic Balancer and reinstall. Re-install the belts. If it is leaking around the edges of the cover the sealant may need replacing. Also check the condition of the sealant around the oil pan. Both would require removal/cleaning and re-sealing.


What are the signs of a blown ring seal?

Blue smoke out the tailpipe--lots of it. If its a blown ring seal, then the oil is being "blown" into the air cleaner, burned up and out the exhaust. Also, the engine oil level will be next to nothing.


Changing a front oil seal on a 350?

This can be quite a job depending on the year of the vehicle. If it's an older vehicle things are a lot easier. Basically, you have to remove everything from the front of the engine so you can get at the harmonic balancer. If you are real lucky you may get by with just removing all the belts. On some vehicles you can get at the harmonic balancer from underneath the car or truck. One way or the other, you have to be able to get at the harmonic balancer. There is a 5/8" bolt in the middle of the balancer. Remove it and use a harmonic balancer puller to remove the balancer. At this point you can see the seal that the snout of the balancer went through. You need a seal removal tool to get the old seal out. Most rental places will have both the harmonic balancer puller and the seal removal tool if you don't. Get the old seal out. Now, take the new seal out of it's package and use a little motor oil on your finger to lube the rubber on the new seal. Put the new seal in using a hammer to tap it into place. This can be a little easier said than done sometimes. Use care not to damage the new seal. Try to get it lined up evenly and just tap it in a circular pattern to get it started. Once you have the new seal in... take a look at the snout of the harmonic balancer and make sure there is not a groove in it from the old seal. If there is one, head to your local auto parts store and grab a harmonic balancer repair sleeve. If all is well you need to use the balancer tool to put the balancer back on. Most balancer tools double as a remover and installer. Make sure you have the key on the crankshaft snout and the groove in the balancer lined up. Once you have the balancer back in place put the 5/8" bolt and washer back in. Use a torque wrench and tighten it to factory specs. If my memory serves me correctly it's 65 ft. lbs. on a chevy. But don't rely on my memory. Now just put everything back on the engine and you're back on the road. This may be a job for a mechanic if you have never done anything like this before. But, it's an expensive job. It's also a good learning experience to do it yourself and save several hundred bucks. The seal itself should be under $20.00 Take pictures of the front of the engine as you remove things. Better yet, get a buddy to video record as you go. It will be a big help when it comes to putting it back together. Also, label everything you can. It's usually a lot harder putting back together than it was taking apart. I would plan on making a weekend of it. Good luck, Guy


How do you change the front crank shaft seal on a 2000 Chevrolet Impala 3.4 liter?

Pull the balancer then the seal. NOT EASY


How do you repair an oil seal leak?

Depends on which seal and which model vehicle, but it involves replacing the bad seal. Rear main seals usually aren't that difficult - though again, depending on the model, it may involve dropping the transmission. Front seals or crankshaft seals involve pulling the harmonic balancer (if you have one), pulling the timing cover (if you have one) pulling the old seal from around the crankshaft and tapping the new one into place.


How do you replace the front crankshaft seal on a 1993 Saturn sl2?

First you will need to remove the Harmonic Balancer pulley from the engine. This may prove to be difficult being the bolt that holds the pulley on is tightened to 220ft lbs. once the bolt is removed the pulley should just slide off. behind the pulley is the front crankshaft seal, use a good seal remover tool to pry the old seal out. reinstall the new seal with a seal installation tool. make sure the crank pulley is tightened back to 220ft lbs.
