Thumbs down Oil leak...

Hey guys. Got to looking under the hood today after seeing a small bit of oil underneath my new 97 d21. I noticed that under the distributor there is some oil pooling close to the block. Also I have oil on and behind the belt and pulleys in the front. No oil on the passenger side, and it seems to be dripping toward the front of the engine on the drivers side. I'll get some pics when I get home. I got a Flickr account today so I could post pics, because my new wheels, tires, and headlights came in today. As well as having a brand new windshield put in. I think it's all gonna look real good. Anyways, any idea about any common leaks in that area. I've searched a lot, but my engine knowledge is complete shit, and I don't see much at all about leaks on the drivers side, unless it's at the rear of the motor. Anything that can point me in the right direction is appreciated.

If you're not sure where the leak originates, it's time to get under the truck and have a look around. Bring paper towels because you might have to clean up some old dirt and oil in order to see the leak. It's not uncommon for front crankshaft seals to leak and it's also common for cam shaft seals to leak. Other culprits are the valve covers and the rear main crankshaft seals.

When it was time to fix my leaking cam shaft seals, they went ahead and replaced everything on the front of the engine. It's one of those "as long as we're in there" deals. Seals, timing belt, water pump, and oil pump.

Seconding the valve cover gasket. It's a snap to change.

Thanks a bunch fellas. I'm gonna roll up under there tomorrow and see what I can figure out. I'd like to learn how to fix my own shit. Guess this is a good place to start. I'm also gonna attempt lowering it this weekend.

Just some FYI: I don't think Flickr will let you post to a forum. You can put a link up, but you can't show the image in your message.

For that, you'd want http://imgur.com or ...well, I don't know what else anymore.

Thanks, JP. Flickr sucks anyway. I just googled image hosting services and picked one at random.

After you upload a pic to your imgur account, click to view it and you should see something like the screen below.



Above is circled the links to click to size the picture.

Click the size you want (Huge generally works good for full size forum posts), click the little Note Icon next to the BBCode url to copy the link to your clipboard, then paste that into your message here.

Also, since you have just started and just bought your truck, you might want to start a build log for it. You can use that to record your mileage, oil changes, new tires, etc. It will give you one spot to go in and see when you did what.

That is most helpful of you, sir. That is a fantastic idea. I had thought about that last night. I'll do that.

And that bike is sweet....

Was sweet.

One of the roller lifters froze a bearing, overheated, and shattered. It turned sideways in the aluminum block, tearing out that hole and ground the lobe off of one of the cams. Steel shavings from the cam lobe and aluminum shavings from the block were carried by the oil all through the engine. They got into the crankcase bearings, camshaft bearings, lifters and piston rings. That whole engine was ruined.

The Harley dealership wanted $4600 for a new engine (XR1200 engines are hard to find used, which makes them almost the same price). After buying the engine, I'd have to pay installation and have it tuned again to fit the intake and exhaust changes.

The bike was a 2009, and tricked out race versions were selling for only $7,000.

I found someone willing to give me $4,000 for it. So we parted ways.

It was fun, though.
