Well here are some pics of the front of the engine. It looks to me like the crank main seal is not doing it's job. Waterpump looks okay but may rebuild it anyway now that I'm "in there". I ask that the higher educated out there please share your thoughts? Thank You.

Jeff: I would remove the belt

Jeff: I would remove the belts, and crank gears. See if any of the internal portion of the seal herniated to the outside. That is what happened to me when I first put the front cover on the crank shaft. I pushed it in with a small screwdriver, but was concerned if the metal spring moved out of place.....so I removed the cover and the spring was OK. I then installed it again, and this time, the seal herniated out, again!!!!!!! Again, I pushed it back with a small scredriver, and left it alone.

It was about 1/4 inch that involuted out.

Hi Jeff,

Although I can&#39


Hi Jeff,

Although I can't say, for sure that the crank seal is the only place where oil is leaking...based on your photos, it sure looks like the culprit. While you have the belts and the crank gear off...take a close look at the inner gear which has a machined surface which rides against the oil seal. I'm of the school that any ridge is not OK...and the gear should be replaced.

Although the front seal of my BB went in without a hitch...I struggled for years with a persistent oil leak into the distributor housing (different set-up than a TR or 512). The solution, thanks to Ferrari-UK, was the replacement of the drive gear that rode on the seal. $65 for the part...and now a dry distributor...

Good luck!

Regards,
David

David: The inner gear rides against a big washer, located between itself and the seal. Jeff: You may want to check the washer for any ridges.

Henry...the inner rubber lip t

Henry...the inner rubber lip that rides on the crankshaft should be biased inwards towards the engine...not outward? Is this correct? I will order a new seal and take great pains to install it as trauma-free as possible. This seal that's leaking was $14 from one of the aftermarket suppliers. It didn't even come with a spring...so I had to get a new spring before installing it. Can you recommend a source for the seal? Thank You.

Hi David: I'll be sure to check the backside of the gear for wear. I can see your point about the suface condition. If it only has minor imperfections, could it be surface ground just a few thousandths to clean it up (I'm thinking something less than .010" max) You have a good point that I didn't consider. Thank You.

Jeff: The inner lip, with the spring, goes towards the engine.......you are correct. I got all my parts from Rutlands. I think it is very important to try and figure out WHY the seal leaked.

"It didn't even come with a spring........" WOW Is this the spring that you made at work......probably had the wrong tension on the lip. This might be the reason for leakage.

If I get a seal with no spring, I will send it back, and get the correct one.

The spring I made at work was the same wire diameter, and I matched it up with the original spring...so I think it was pretty close. The more I read all the advice, the more I think I simply screwed it up upon installation. I will call Rutlands tomorrow. Did you get those copper sealing rings you needed?

Yes. I ordered a couple from Algar.........will try to match them up with a metric supplier.

Be careful, in hitting the seal into the front cover, while it is on the car. Remember, there is no support of the cover, in the seal area, on the engine side. I feel one can crack the cover, if the seal is hit too hard....yet, one wants it in correctly.

Seal installation....darned if

Seal installation....darned if you do and darned if you don't. I will take great pains to do a good job this time.

Was Algar's price acceptable? The place I used was okay, but you had to get many more than you really need. My offer still stands if you need some extras as I still have some left. It surprised me just how much I had to torque down the banjo bolts to get the rings to "crush". I tightened them down, started the car, fuel leaked slightly, and I continued to tighten things down bit by bit till the leak stopped. I was sooooo worried about stripping out a fuel distributor....that would have been the pits!!!

I ordered 2 of each size......

I ordered 2 of each size.......there where 2 different ones. One was $0.95 each, and the other $0.45 each. Not bad if one only needs a few. But, I will be doing fuel pressure tests, in the future, and since they should not be re-used, I feel I would need a small handful of them.

I will measure them, and try to find a supplier that will sell like 50 in a box........for just a few dollars. One does NOT want to take a chance, when it comes to a possible fuel leak. You stated earlier that yours are slightly different in size. Thanks for you offer.
