one of my engine builders told me the best ones always have a little leak!

Flying Finn

I'd take care of it. Especially if it's from valve covers which is a very easy to fix.

Us guys with lexan windscreens will thank you for fixing the leak. I too have been stuck behind a "misting" car more than once.

Your car doesn't leave a drop?

Geoffrey

No, you can eat off of it.

Venison?

geez. i hope you guys never attend a vintage race! pretty much with at least half the vintage cars they are seeping/burning/leaking just about every fluid that they carry! lol! my Super Seven is pretty good about it; it will weep, but not enough to do more than crud up the engine bay and down by the tail shaft and rear diff a little, too. most of those older motors just don't seal up very well, and they have blow by issues, too. the old style cork gaskets and rope seals don't particularly help much, either. check out the vid below and you will see what a pack of formula fords and Mallocks and whatnot can leak! (my poor old camera was soaked in fluids by the end!!):

they started me in the back of the 'fast' pack because they had moved me from small bore (where it would have been a case of 'lets see how many times i can lap the entire field in 20 minutes; the next fastest car was 9 secs a lap slower than i) to Open Wheel/Sports Racer. i was the only 'street car' in the heat! near the end, the lead S2000 had a rear upright failure under braking and crashed hard into the tire barrier; he was ok, but the car was pretty much wrecked and he was very stiff the next day. i'd have gotten him in the next lap or so, anyway (either under braking coming into T1, or braking going into T5 at the bottom of the chute, just as i got that very strong Mallock).

anyway, you can see the fluids flying up from the front pack; it really doesn't bother me; its all part of the race, and of the game! i don't mind racing with a car that is misting or weeping a bit; i'm not too happy when there is enough fluids coming out to make wet marks, though. thats 'too much' and the car needs to come in and retire.

Pffff....

You might let a little fart squeak out your **** once in a while. It's good for your disposition. I've been doing this for 18 years, and for that 18 years I've been cleaning oil off my windshield, mostly always from 911s. Anywhere from a little mist to a full 10 quarts. The mist is just part of the game when you drive on a track with 911s. I've learned to accept that. Anybody that thinks a little mist is gonna wreck somebody needs to have their colon examined. It's the 10 quarts all at once I can really do without.

Oh... and try not to take yourself so seriously. You'll have more friends that way, and you might develope a sense of humor in the meantime.

The 964 motor that Chris Cervelli built for me was dry as a bone too. My '84 Carrera motor was dry, both stock and after a full rebuild. My old 914 2.0 motor was also dry. They don't have to leak.

Hey guys, thanks for all the input!

FWIW, here's my "history" on this issue:
I had turbo VCs already, then replaced the gasket as a part of a recent valve adjustment (and clutch replacement). It had seeped prior, but only at track; dry on the streets.

Seeped again with that new VC gasket. OK, so I'll go billet route: ordered Hargett alum VCs with the 964 runner o-ring. Fine on the street; perfectly bone dry! Seep on the track. Again, minor, but enough to lightly mist the rear end. OK, so I tighten up the VC nuts just a tad for Sunday's sessions ...ugh, still seeping. And yes, I checked pretty darned closely that no oil seems to be coming from above the VCs; all looks really dry, not to mention apart from this issue, the engine is all dry and seep free!

Currently: just replaced the rubber o-rings again, was extra careful that I did not overtighten nuts, and all is good again on the street; bone dry. I hope it'll be fine for this weekend's TT.

I posted this up to you all because I am wondering how much time/energy should I spend on this. While I understand I don't want to **** off any of my cohorts on the track, I also realize this is somewhat part and parcel of being out here, no? And Thanks, John (Redline man) for your sentiments!! Afterall, I put up with innumerable other cars' maladies w/o complaint. Your thoughts and advice most welcome. TIA!

Sure that is where it is coming from the VC and not just the oil drain tube O-Rings. Also keep the pointy end of the car forward on the track could help.

Flying Finn

OK, you've done quite something already.

Have you asked fellow trackers if it shows up on their windscreen?

I'd think slight mist that only shows up on the rear bumper isn't enough to cause problems for others. Maybe some "grime" on the nose but nothing that affect handling etc.

This reminds me of a "case" I watched at SP a few years ago. A 914- 6 was having a hard time keeping the VCs from leaking on the headers. Nice and dry idling in the paddock but not so good on track. Spent day one dithering around cranking on the VC nuts and the like. Early day 2 he hosed the track after the case pressure got high enough. His cost his group almost an entire run.

There is likely a reason you are having a hard time sealing the motor. Case pressure from high blowby or a blocked breather system should be looked into.

Edward

Hmmm, thanks kurt. That is something I had not thought about ...will definitely look into that! Much appreciated!!
