Car Forum / Nissan / Nissan Cars / February 200896 Sentra leaking oil by distributor... Need info
My 96 Sentra GXE is leaking oil. I inspected it closely and noticed that there is quite a bit of oil on the underside of the distributor and the surrounding area. I took off the distributor cap today, and, it was not wet on the inside of the distributor. I would appreciate some thoughts about where this leak may be coming from. Thanks > My 96 Sentra GXE is leaking oil. I inspected it closely and noticed > that there is quite a bit of oil on the underside of the distributor > and the surrounding area.

Thanks The distributor is connected to the exhaust cam. There's a seal that prevents the oil from the overhead cam area from leaking to the distributor area. Over time that seal breaks down. You should replace the entire distributor because the cam position senor is part of the unit. If you haven't done so already, you will start to experience drivability problems from that leak. You can find distirbutors on Ebay for about 150 to 200 or get one from the parts store for 300-400. It's a bit pricey, but it will last for the entire remaining life of the car. Not the cap and rotor, of course. That still wears out regularly. CD > The distributor is connected to the exhaust cam.

I know this has been covered already, but isn't there *any way* around the problem of a failed seal in the distributor? Between $150 and $400 from the loss of a damn seal. Little story: Back in the '70s, the door latch on my old Ford failed and I had to tie the door shut . The dealership's mechanic said ~$130 to replace the latch mechanism. Well, I didn't have $130 and what did I know about car repair, so I drove home with my door roped shut. Poking around the door with a Phillips screwdriver I removed a plate and found exactly what was wrong. Rust had destroyed a little spring in the latch (like it was destroying the rest of the car). Ace hardware had an almost exact fit, and the door latch was good as new. Cost: 10¢. That's where I'm coming from. > > The distributor is connected to the exhaust cam.

Nisstech mentioned in his post about replacing the seal. Perhaps he can describe that a bit more? As far as I could tell from the distributors I've replaced, that seal wasn't a serviceable part. It was integrated with the distributor.

SignatureJim Yanik jyanik at kua.net If no oil is getting into/inside the distributor there is no need to replace it. You may want to look and the valve cover gasket for leaks and you may want to replace the o-ring on the shaft of the distributor, they tend to get hard over the years and will leak. > My 96 Sentra GXE is leaking oil.

I would appreciate >>some thoughts about where this leak may be coming from. Thanks You're right. My apologies. I incorrectly read that there was oil inside the distributor. The OP was describing the leak as all around but not inside. I was unaware that just the o-ring of the distributor could be replaced. Which part is that which I can get separate from the distributor?
