What would cause oil to blow out the top of dip.

A clogged PCV hose, valve or intake passage to the PCV system could cause this.

Could be a cylinder wear problem-Try to do a cylinder leakdown test and reconfirm

THE LOW COMPRESSION IS PROBABLY A SIGN OF CYLINDER/ PISTON/ AND RING WEAR

YOU PROBABLY ALREADY THOUGHT THIS.

WHAT WAS THE COMPRESSION PRESSURES ON ALL OF 'EM, BEFORE YOU TOOK IT APART?

INSPECT THE PISTON FOR A POSSIBLE HOLE, LOOK AT THE CONDITION OF THE VALVES ALSO.

DOES IT RUN GOOD?

IF IT WAS "JUMPY OR STUMBLING" MAYBE YOUR TIMING IS OFF---THIS MIGHT DO SOME IRRATIC SLOSHING.I MAY CAN HELP YOU IF YOU AREN'T UP ON HOW TO DO IT CORRECTLY

I'VE HEARD PEOPLE OVER THE SAY THEY THOUGHT IT COULD BE A HEAD GASKET OR EGR ISSUE---NOT. THESE ARE THE SAME PEOPLE WHO BLAME EVERYTHING ON VAPOR LOCK!

OTHER STUFF TO CONSIDER, WITHOUT ME KNOWING THE SITUATION FULLY

OIL OVERFILLED. DIP STICK RUBBER SEAL INTACT. WAS IT "PUFFIN' " SMOKE OUT OF THE HOLE OR PCV HOLES ON THE VALVE COVER. IS THE PCV SYSTEM STILL INTACT AND WORKING CORRECTLY?

HOW MANY MILES ARE ACTUALLY ON IT? (70K SOUNDS TOO FEW, FOR AN '82) MAYBE 170K?

ON OUR JEEPS, MINES A '77 CJ5 w/258 SIX CYL, THE AVERAGE ENGINE LIFE EXPECTANCY IS PROBABLY AROUND 150,000 MILE. THAT'S SORTA WHERE I'VE BEEN SEEING THEM READY FOR A REBUILD. MAKING IT THAT LONG, MEANS THEY WERE KINDA TAKEN CARE OF.

I'VE HAD 6 CJ5s, AND A '46 WILLYS ALSO, I GOT 'EM BOTH IN 1991. IN 1993, I PUT A HIGH VOLUME OIL PUMP IN IT AND GOT MY PRESSURE BACK BETWEEN 40-60 PSI. IT IS MY DAILY DRIVER AND AND FINALLY IT STARTED SMOKING MORE THAN "I" COULD PUT UP WITH (WHICH WAS NOT REAL BAD, BY OTHER PEOPLE'S STANDARDS!). THIS WAS AROUND 140,000 MILES. BUT STILL DRIVING!

I CAN'T LIVE WITHOUT MY JEEPS, IN 1995, IT WAS TIME.I HAVE A BUDDY WHOSE MOM HAD DIED YEARS AGO, THRU THE GRAPEVINE, I HEARD HE WAS GONNA SCRAP HER "1976 AMC HORNET", WHICH WAS BURIED IN THE BUSHES BEHIND HER HOUSE. A LITTLE SWEET TALKIN', AND HE GAVE ME THE ENGINE, IF I'D REMOVE IT.

BEINGS THAT IT TOO WAS NO SPRING CHICKEN EITHER, HER 258 WAS GONNA BE MY "BUILD MOTOR". I AND ANOTHER FRIEND, TOOK OFF THE HEAD, WITH A PIPE AND CHAIN, WE MAN-HANDLED THE ENGINE BLOCK OUT. IN THE BUSHES!

IT WENT TO THE MACHINE SHOP. ONE PIECE AT A TIME. BLOCK. THEN CRANK. THEN HEAD. RODS AND PISTONS.I WAS FINANCIALLY CHALLENGED. YOU KNOW, I STARTED OUT WITH NOTHING, AND I STILL HAVE MOST OF IT LEFT

AS I GOT EACH PIECE BACK, I DID WHAT I COULD TO PREP IT FOR THE NEXT TO COME BACK. SO LIKE MY BLOCK GOT PAINTED REAL GOOD, WHILE WAITING FOR THE CRANK

SHE SAT ON THE ENGINE STAND, FOR ABOUT 2 MONTHS BEFORE I GOT IT ALL READY. AND I WAS STILL DRIVING THE JEEP!

RIGHT OFF THE BAT, I PUT IN A HIGH VOLUME OIL PUMP, THE LAST PART I NEEDED WAS THE OIL PAN. THE "HORNET'S OIL PAN" IS NOT THE SAME AS THE JEEP.

I WAS VERY PICKY THROUGHOUT THE WHOLE PROCESS----I REPLACED THE CLUTCH AT THE SAME TIME----ALL PARTS AND MACHINING COST ME RIGHT AT $1500.00. BUILDING AND ALL LABOR WAS. ME!

THE NEXT EARLY MORNING SATURDAY THAT CAME UP---I SNATCHED MY ENGINE, REMOVED AND CLEANED THE OIL PAN, AND PAINTED IT WITH SEVERAL COATS. I GOT IN THERE AND CLEANED THE ENGINE COMPARTMENT, REMOVING ACCESSORIES, PAINTED IT RED INSIDE. I DID WHAT I COULD WHILE IT ALL SAT IN THE SUN AND DRIED. SLAPPED IT ON, INSTALLED MY "NEWLY BUILT ENGINE". STICK ME WITH A FORK, I WAS DONE AND DRIVING, BEFORE 1600HRS. PERFORMED ALL BY MYSELF

DID USE THE ENGINE HOIST, ALL DONE IN THE CARPORT, AT MOM AND DAD'S HOUSE, I LIKE THE "ENGINE SWAP" IN ONE STEP PROCESS. STUFF AIN'T SCATTERED EVERYWHERE. YOU 'MEMBER WHERE IT ALL GOES. YOU DRIVE IT THE DAY BEFORE, AND THE SAME DAY YOU SWAP

THIS BEING THAT "I WAS OLDER" AND NOW REALLY TRY TO "OVERKILL" MY MAINTENANCE----SINCE THEN---I REPLACED A CRACKED HEAD (ON BOARD IN 2003) AND WENT FROM THE ORIGINAL CARTER BBD CARB---TO A WEBER 32-36 PROGRESSIVE CARB---NOW I'M HAPPY WITH THE HOLLEY 390 CFM 4 BARREL I INSTALLED. IT'S THE TICKET!

SO HERE'S SORTA THE HISTORY AFTER REBUILD IN 1995

AFTER THE 5TH OIL CHANGE (500 MILE INITIAL BREAK IN) 4 MORE EVERY 3000 THEREAFTERON THE 6TH CHANGE (GOOD BREAK IN TIME) I STARTED USING ONE QUART OF "LUCAS OIL STABILIZER" WITH MY 4-1/2 QUARTS 10W40 HAVOLINE OILHAVE DONE THIS EVERY OIL CHANGE SINCE! IT DOES COST MORE, AND HERE LATELY EVEN MORE!

---I REPLACED THE TIMING CHAIN TWICE (A LITTLE NOISY, HAVING USED BOTH GEARS MADE OF METAL). INTERVAL?

----HAD ORIGINAL HEAD MACHINED, REPLACED THE CRACKED ONE IN 2003 (HENCE, BLOCK IS STILL BLUE, HEAD IS NOW GRABBER GREEN!--2003)

----OTHER THAN THAT, THE SHORT BLOCK IS STILL THE SAME INSIDE----I DRIVE "MR. JEEP" EVERY DAY, IF I'M NOT DRIVIN' "WILLY" (MY '46)---I HAVE RIGHT AT 213,000 MILE ON THE "ENGINE" NOW.I HAVE A "HINT" OF SMOKE WHEN I START IT UP----VACUUM GAUGE IS READING 21Hg STEADY.

I FIGURE I CAN GET ANOTHER 2 YEARS OUT OF THAT ENGINE

I STARTED BUILDING "WILLY'S" SPARE ENGINE A FEW MONTHS AFTER "MR. JEEP'S"---I USE LUCAS IN HIM TOO---AFTER A GOOD BREAK-IN PERIOD---HE DOESN'T GET THE MILES THAT THE CJ5 DOES

LEMME KNOW WHAT YOU WANNA TRY. AND IF I CAN HELP

IF YOU'LL LOOK AROUND IN THE 2CARPROS CJ 5 AND CJ 7 FORUMS, YOU'LL SEE SOME OF MY "HELPIN'"
