well, i have some ideas, but they are not good. it looks like it is coming out of the dipstick tube, or around the breather box (?) under the oil filler neck. it is not leaking a huge amount, just getting the top of the engine wet, with some oil pooling on the engine tin.
i have replaced the gasket between the engine and the breather box thing. that seemed to do it, but only for short drives. today went about 20 miles, and fresh oil was on top of the engine.
it seems to be coming out laterally, and not really spraying all over; just flows around after it is down.
any ideas? thanks ahead of time.
dude, you know that clip thing that holds the breather down??? right, that one....anyway, wrap a insane amount of duct tape around the bar where it makes contact with the breather box cover thingy (2 places--left and right).....so like try that, duct tape is like free.....?

so, it is possible that the spring clip is weak, and does not provide the tension needed? that would be consistant with the observation that the amount of oil leaking has decreased, but not stopped, with the installation of a new gasket.
any other possible leak points?
Several. The dipstick tube could be cracked flush with the tin. The Distributor O ring could be be old, broke, or even missing. The oil pressure sender. Any and all of these will cause oil leaks that blow all over the top of the engine.
i thoght about the oil pressure sender and the dizzy o-ring, but the leak appears to be on the opposite, i.e. driver's side. the spray pattern points in the direction of the breather box, but the dipstick tube crack theory needs to be checked out. are those tubes press fittedinto the case, or threaded, or what? there is a blob of gray stuff on the tube, hardened; an old fix of some sort?
thanks for all the ideas.
That blob of grey stuff is most likely JBweld. A previous fix. That hole in the tin should have been bigger with a grommet imo. Unvented heads can cause enough back pressure to overwhelm that gasket.
Britt, if I see duct tape on your car, I'm gonna hunt you down and make a mummy outta you with that same roll of tape!
The dipstick tube is press-fitted, if yours was cracked, a DAPO might have decided to JB weld instead of fixing it properly...
The dipstick tube was one of the few things my car's DAPO got right
masking tape wurks gud to. show a picture of the mess shane. there is a gasket in between the funnel top and the sq base too.

a couple decades ago we would have said, "dude, that is, like, so way totally gnarly hacked to the max. dude."
Kevin, i didn't realize there was gasket under the funnel. i will investigate tonight. i will also look closer at the dipstick tube. also Kevin, i have not the technology to post pics of the area, as that technology frightens and confuses me. i also have not yet been able to justify the cost. "really, honey, i need a digital camera so i can show the guys on the club website pictures of my car." nope, i don't see that one flying.

i hear ya. i have no cell phone, top that! the camera i use is the one jeanne got with her gates tlp grant. drive down and I'LL take the picture for you. i have tape though.

Eric and red:
Shane,
If I can deviat for a moment and get back to your question;
The dip stick is a viable source of the leak - especially if there has been any fix there in the past. Some others to look at are:
thanks for the insight, Gerard. i suspect that after 33 years the bail might need rebending a bit. the gasket sealer stuff sounds like i should get some. i hope this isn't my dipstick tube; one of the places oil pools is on the TOP of the dipstick flange. go figure.
i will investigate and repost. thanks again.
Kevin, i may take you up on your offer of duct tape someday. but more importantly, i wonder where you got your synchrometer with the wide neck (for outside carb throat); everyone i have spoken to only has the rubber cone for inside the carb throat.
Clean everything up really good, spotless, no oil. Run the daylights out of the thing, so you know it's spit oil wherever it's leaking. Park the car in the garage and wait until dark. Pull out your handy-dandy groovy mini blacklight, 'cause engine oil, transmission fluid, and other petroleum based products will flouresce under the most hip blacklight!
Perry, not only do you sell awesome brake rebuild kits, but you know the most kewlest of little tricks! i had no idea you could be so kewl from tennessee; but i have never been there, so how could i know?
thanks for the tip!
it fits inside my velosity stacks. you have pretty small carbs! . that brand is all the same. your 34(?)s have no single stacks?
k
the 34s have just a throat. not really a stack. your synchromter fit perfectly around the outside of it. inside there is a squarish thing which prevents an inner seal. all the synchrometers i have been ready to buy only have the rubber cone, not the sleeve/cuff thing on the outside of the synchrometer body.
off to look at oil leaks. thanks, as always, Kevin.
ne winfo/ speculation. oil only appears after engine gets good and hot, then seems to be spraying (?) from about the height of the gasket on the breather assembly (if that is what the think is called that the oil filler ncek bolts to), and only on the left side of the car. not a lot of oil is involve here, though i only had an hour total run time on saturday. so, here is my ideal...
last fall i put on new breather tubes, and i used 1/2 inch fuel line from the FLAPS. is it possible that the fit is not snug enough to keep a tight seal after the rubber warms up? the leak seems to come from the area around the three way fitting by the dipstick tube.
opinions? would hose clamps fix it? i guess i could try.
shane, i was at ovals on sat and picked up a few extra cork seals for the square base. there should be a gasket under the funnel portion of the fill tower, is there one?. wipe everthing down with cleaner and check again? the leak point should be pretty evident.
k
Shane,
The three-way you're taking about is a viable source of leaking. Two of the hoses come from the heads. The thrid hose, on top, goes to the air cleaner. Because its a tight fit there, I've opted for a spring clip type of clamp. They seem to on reasonably easy with a plyers. I also use the fabric-coated vacuum hose for these rather than the straight rubber hose.
Enjoy - and stay dry!
Kevin: i have replaced the cork gasket, and yes, there is a rubber o-ring under the funnel. all is good there.
Gerard: as for the three way fitting, that is the plan for after work tomorrow is to put new hose clamps on all those babies. i hope it works.
i dribbled oil on my driveway tonight, trying to adjust my new headlights; hella vision plus H4 with yellowstar bulbs! very kewl...
those fancy lights will illuminate the mess in the driveway quite nicely. no driving at night with just the fog lights.
k
the yellowstars project a yellow light, which mixed with the pilots makes for an awesome light spread. check out www.rallylights.com; they ship when they say, and the prices are good!
ok ok, i have hose clamps on the breather hoses. took the car to work yesterday, about a 40 minute drive. very fun, btw. leaked oil out of the same nondescript place. soo...
this morning i was poking around and felt that the breather box could tip back just a hair. so, off comes the clamp, previously thought to be tight, and with the help of vise grips and a pair of channel locks, put a bit more of a bend on there. we shall see if that works. the spray pattern always looked like it cam from that area. stay tuned for an update this afternoon or evening.
well, it still leaks.
after getting the engine good and hot ( a 45 minute drive home) i popped the engine lid and looked inside as a held it at 2000, 3000, and 4000 rpm. nothin'. couldn't see from where all the oil on the engine could have come from. it was there, but nothing else was added as i was watching. hmmm... back to the drawing board, and thinking board.
if anyone reads this, and you have an idea, i am all ears. thanks!
a little to add to my questions:
is the crankcase pressurized? i know that at 2500 rpm oiil pressure should be 42 lbs or so, but is that "pressure" as in blow up a ballooon pressure? could this be combustion blowing by thge rings?
i realize that my questions make it very clear how little i know, but you are all tolerant and understanding, right?
thanks ahead of time.
Shane,
Did you determine that all the "top-of-engine" oil problems we re resolved? Is everything sealed to prevent leakeage?
If so. Do you have some way of looking under the car (aside from running yourself or someone else over with it )?
You really need to get under the car with a light so you can trace where the oil is coming from. Looking from above just won't cut it in most cases.
Can you get any pictures - that would help us?
alas, no digicam. i determined that the oil leak was coming out of the top because that was where the oi8l was pooling. also, clean, new hoses would be spattered with oil after being cleaned. this is especially true right next to the oil filler /breather. some of the oil drips down underneath, but a wiped clean top get oil pooling on the tin and block.
i have looked underneath and nothing looked like it was dripping.
i still need to mess with breather tube attachment piece on the breather (the little plastic neck thingie), and perhaps the oil cap. does that have a gasket in it? because mine does not, just plastic.
more investigating tomorrow, after painting the living room ceiling.
thanks, Gerard!
Shane,
Yes that cap is supposed to have gasket to seal properly. Sounds like you may have found the problem. Check on the filler neck to see if oil has accumulated there at all. If so, then thats the source.
Good luck.
