I'd modded my Audi to remove that little switch from the circuit, so I could move it to the side of the road with the starter motor and got used to starting that car by reaching in thru the drivers window. By the time the Quattro had gotten old enough to vote, the electricals were a little flakey - if you lost the signal from the "goose-neck" water temp sensor, K-tronic would adjust by instantly killing the engine until you got out and wiggled the connectors.

Sorry for the trouble ...

Oh that isn't even a personal best (ie worst). In high school I wanted to hang out with the cool kids, so I came across a 1959 Mercedes 190a for $65. (Not a typo). The catch was that the engine was seized. I bought a Chilton manual and did everything it said in the engine rebuild section. While I was waiting for a crank regrind, I fixed rust, cleaned polished and painted *everything* including the engine compartment. When I'd gotten engine back together, a friend and I did a marathon session to get it back into the car, which we accomplished by about 5 am, but didn't reinstall the hood. We tried to start it, and it didn't start. There were some leftover questions about the cam timing, so we took off the valve cover to recheck where the chain was set on the sprocket. Then tried to start again, but the battery was too weak.

Then in the fog of early morning (literally and figuratively) we got this brilliant idea. Let's tow it! Hooked up his Fiat 850 (you guys don't know what the phrase "no torque" means until you've driven a Fiat 850). So, clutch in, he pulled me up to about 30 mph, and I dumped the clutch. Just our luck, as soon as I did that it started raining, so I hit the windshield wipers -- which went "swish, sswich, sssswish, ssssssssssswwwwwiiiissssh" , and stopped. Darn battery - not. The car still hadn't started and by then we were going about 5 mph as 850cc of Italian ponies couldn't drag the carcass of a Benz along. I stopped. He got out, laughing hysterically. I'd never seen a OHC engine before this one, and of course the lower part of the chain dips into the oil pan for "splash" lubrication. This, the cold oil, the "pumping" chain, and the lack of a valve cover or hood, resulted in a geyser of straight 40W shooting up in the air about 10 feet and coating the entire car from stem to stern. There was about a pint left in the oil pan.

I will say though, that it remained pretty much rustfree for the rest of the time I owned it, though the *body* continued to drip oil anytime it sat in the sun for months afterward.

I am bested!!!!
Maybe---?
Does forgetting to put the oil filter back on and cranking the car up only to notice no oil pressure --say "what the ----?" and then panic-- count? It dumped all the oil out in 5 sec's.
Lesson learned if 2 or more people are working on the same car have ONE person doublecheck everything!

I think you should blame that one on L8APEX since it was his car.

You two are reminding me of the time that I broke a fitting on my '79 FB and vented the remaining Freon and a lot (OMG it was a lot!!!) of AC system lubricant all over me and the entire engine bay, the underside of the hood, the windshield and roof.

Regarding the matter at hand, if I correctly understand, the rotors are dynamically balanced and increasing the oil pressure seems to have a positive effect on that (I'm recalling Denny's observation.. what was the term... "silkalicious"?).

I have come across some mention about chatter marks on the housings of machines that see extended time above 8K rpm, and I am wondering if this modification might offer some extra assistance in this regard.

I am also wondering if the increase of pressure might have a positive effect on the volume injected by the MOP.

Can you guess what happens when you're 16 yrs old driving your 14 year old buddie's dad's 65 restored corvette in freezing rain and you shift to 4th gear and punch it in Indiana in January? Picture an old WW2 fighter aircraft with retractable landing gear. Now picture that landing gear is the rear suspension of the vette.

Then there was the time I rolled my new M3 entering an on-ramp at Mach 2. Paper license plate still in the rear window. Have you ever looked in the back seat and seen your two best buddies hanging upside down with their seat belts on laughing their asses off? The funny part was when we all had to push the red seat belt release buttons and crash our heads on the headliner.

HiFlite, where the hell did you live back then? Certainly not in MI! I never heard of a 190a, and had to look it up - I sure as hell never ever saw one on the road in the states! Ditto for the 850.

I've been wondering the same thing. Additional smoothness must be a good sign.

It will be hard to prove but silkilicious continues.
I have noticed an increased omp oil use but i dont see how that is possible and and i am just crazy.


back in the 60's my best friends father owned a juck yard. Needless to say we would get old jalopies running and have our own demolition derbies (before they existed).
I can tell you this a 53 chevy would not make a good rally car and it doesnt like jumps at all.
Packards and Chryslers were the best. So much METAL---yeeee haaaa--those where the days.

cars, girls, and oil pressure

We were a strange group of kids ... in southern Indiana. The first car I drove on the road, illegally, was a 1958 Fiat 1200 Roadster. I promptly spun it into a ditch; my excuse was it had 3 different-sized tires out of 4! The Fiat 850 sedan/coupe was I think a 1969, and had the high compression engine with around 50 hp, which did ok with a car that maybe weighed 1200 lbs.

http://en.wikipedia.org/wiki/File:Fi...ort_1969_1.JPG

One day, somebody bet my friend that he couldn't jump the 850 over one of those concrete block things in the high school parking lot. He took the bet, unfortunately picking a parking block that had about 4" of rebar still sticking out of it. He got half-way over, until the rebar punched through the bottom of the passenger side floorboard under the rubber "carpeting". Unfortunately, the forward momentum of the car was dissipated by bending the rebar and effectively stapling the car to the ground. It took the entire hs band trumpet section to pick the car up and move it around until it came loose. The rip in the floor with right where the spray for the right front tire hit when it was raining. I rode with him often in the trips back and forth to college - and when it rained the water pressure would lift the rubber enough for water to come in, but acted like a diaphragm valve when the water wanted to come out. The passenger footwell would fill up until the whole car was 3" deep in water which only 'drained' when you opened the doors.

Then there was the time we lost one of our good VW motors - cause a couple of guys got drunk at the drive-in **** movies (the freight trains would stop for a while to watch from the nearby tracks, then pull ahead and stop again for the guys in the caboose to watch for a while) and fell asleep going home. The VW putt-putted across a corn field, went into a river, drifted for a couple miles downstream, where it lodged on an island - and it still sits to this day I'd imagine.

Or the time another friend was making nitroglycerin in the garage, knocked off a jug of the unprocessed mixture onto the concrete floor, and blew up the garage together with his parent's matched pair of 1967 T-birds. (He was deaf for a few days - any brain damage would have been unnoticed.)

Or another friend who set the still-standing over-the-speed limit for the town of 139.5 radar-timed mph in a 25 zone in front of the high school. It was a legendary AAR 'Cuda with a 340 ci triple 2-barrel carb factory original setup - I drove that thing a few times -wicked.

Or our little plot on graduation day: opening the doors at both ends of the looong high school main hallway - and doing a wheelie on a trail bike the whole length.

Or the Lamborghini 350 GT that one of the guys picked up for almost nothing from a Cadillac dealership. They'd sold the thing like 3 times, but it'd quit running after a hundred miles or so. Had this little brainstorm, bought it, and pulled all the valve shims out (lots of em it's a V12), laid them on the garage floor, beat the heck out of 'em with a hammer and re-installed. Ran perfectly after that! Got it up to about 170 mph at the local airport before running out of runway. Unfortunately the main company's corporate jet guys complained when we beat them in a drag race one night.

Then add hot girls to the hot cars .... but I'll skip that part, other than saying the loss of bench seats was a major blow both to the auto industry and male hormones. Kids these days don't know what fun is!

uh, back on the subject ... I made some extensive comments on the oil pressure thing over in the Mazmart mod thread that are perhaps of interest.

S2 Oil filters

Someone asked about getting these 09 and newer filters at a good price:

Great news!
Earlier I took apart an OMP, and I have to say, it has not very tightly sealed inner parts (cylinder-pistons-plungers), so the higher pressure at the OMP's feeding drill can help on higher oil rate as less oil flows back instead of getting to the nozzles.

Hmmm... this alone might be reason to implement this mod, though I now have to hold off because there's some question as to whether my original 2004 vintage engine is suffering from loss of compression (starts quick and easy when cold but is fussy to start when warm). I'd hate to go to the trouble of installing the mod only to have to pull it off to transfer it to a new engine. On the other hand, the extra oil injection might help is the problem is only slight.

In any event, either in this engine or the next one, this mod is going in.

I didn't write much, err.. at all, here lately.
Many of you earlier posted that the previous rotaries had higher viscosity oils as a factory choice so i picked my manual again to look at the oil specs for our cars.
The suggested grades range from 0w30 to 10w30, with the 5w30 dexelia in the middle.
Do you think that Mazda may tell you not to go abowe the 30 grade because of the reduced oil pressure, IE indirectly admitting that the under-pressured (from the earlier rotaries) oil system may not be adequate?
I didn't notice a real oil pressure change while switching from 5w30 to 10w40 but...

What do you guys think? Please leave alone the 5w20 bullshit :p what i want to know is why mazda says to change the cold viscosity while keeping the same hot one!

Yeah...G...well my 09 Japan Printed Owners Handbook says and shows ALL oil grades can be used from 0W50 to 20W50...pick which one you like for your local climate..

BORING.......
