Todd,
1. The engine was sitting for a year or less, and was run 3x while parked
in December '05 all was fine!
Is the engine original? If so, about how many miles?
THE ENGINE APPEARS ORIGINAL. I DID NOT CHECK THE NUMBERS OR HISTORY (DO
NOT KNOW PREVIOUS OWNER).
BOUGHT IT FROM A MECHANIC DEALER WHO HAD THE TITLE AND REG.
THE TITLE FROM PREVIOUS OWNER READS 150,000 FROM 10/09/02. THE ODO. READS
50,000 NOW. AND THE ENGINE HAS THE OLD RING ON THE AIR CLEANER THAT READS
"ROCKET 88' WITH A ROCKET ON IT. THE ENGINE VISUALLY LOOKS VERY GREASY OVER
THE ORANGE PAINT. THERE IS SOME OIL LEAKING AROUND THE TOP GASKET WHERE THE
PLUGS ARE. IT NEEDS A GASKET ON BOTH SIDES ON THE TOP (NAME OF GASKET?) I
MAY BE ABLE TO LOOK THE GUY UP AND ASK HIM ABOUT THE CAR. (DO YOU THINK IT
IS WORTH THE TROUBLE?) WHERE ARE THE NUMBERS ON THE ENGINE TO SEE IF IT IS
ORIGINAL WITH THE CAR? IT IS AN FOUR DOOR DYNAMIC 88 HOLIDAY THAT APPEARS
TO BE AN ORIGINAL CAR THAT WAS DRIVEN UP TILL 2005 WHEN THE PREVIOUS GUY HAD
A CRACKED END OF THE LOWER PASS. CONTROL ARM (CHANGED IT NOW). I WAS TOLD
THE PREVIOUS OWNER DROVE IT EVERY DAY.
2. Started it yesterday and the engine was "missing" like a shake while
in idle.
How long did the engine run before you shut it off?
I STARTED IT FIRST WITH A JUMP AND STARTER SPRAY AND IT RAN FOR A FEW
MINUTES AND STALLED AND WOULD NOT START.
THEN I STARTED IT AGAIN 2X AND IT RAN A LIKE 1 MIN AND SEEMED TO NEED GAS IT
STALLED.
ADDED 4 GALS 93 OCT AND RAN IT FOR 20 MINUTES. I STARTED IT WITH THE SPRAY.
I DID REV THE ENGINE A FEW TIMES.
IT USED 1/8 TANK OF GAS IN 20 MINUTES. THE SHAKE WAS AT THIS 20 MIN RUN.
My immediate reaction is either a piece of carbon is stuck under a valve
or one or more lifters aren't pumping up. For the lifters, it could be the
internal plunger spring is old and weak or affected by varnish and gunk.
For a piece of carbon stuck under a valve, simply taking the car out and
running the engine hard might clear it. That could also clear a stuck
spring(s) in a lifter(s) with full volume hot oil going through the
lifters.
I WILL RUN IT AS SOON AS I CAN GET IT OUT FROM THE BACK OF THE LOT AS IT IT
BLOCKED BY A CAR.
One other posibility, which goes back to the age of the engine, is the
rings are stuck and the engine is not building up enough vacuum at idle to
run properly. Did you accelerate the engine and does that smooth out the
miss and shake any? If it does at least a bit, then I suspect stuck rings
or collapsed rings. If that is the case, running a can of RESTORE in the
engine oil should free up carbon/varnish stuck rings after about 2-3 hours
of running on the road. After that, switching to a synthetic engine oil,
like Mobil 1 10/30, should clear up the rest.
IT SEEMED TO RUN SMOTHER WHEN REVED TO A HIGH SPEED. IDLE IT SHAKED A LOT.
OK MAYBE RESTORE CAN...OK WHEN I TAKE IT OUT ON THE ROAD? THE 10/30 NOW?
HOPE IT DOES NOT NEED ENGINE WORK!
3. In December I added high test 2 gals. gas with small amount of lead
additive.
4. Added 4 gals more of gas as it was out of gas yesterday
5. Any ideas of what to check to correct this?
In my experience, if a vehicle is going to set for a long time, don't
start the engine periodically, unless you're willing for it to run for at
least 30 minutes and get it good and hot, with accelerating it several
times. Short periods of running never clear out carbon formation in the
combustion chambers and won't get the engine hot enough to vaporize
crankcase contaminates. Short engine runs can lead to cold internal crap
formation, for want of a better description.
OK THANKS...SHOULD I ADD THE STUFF NOW?
OR WAIT UNTIL I GET IT ON THE OPEN ROAD?
I BOUGHT POINTS AND PLUGS SO I AM DOING THAT TOO.
THANKS
TODD
