please explain your question?
is your problem..that it is using oil/
statement: does use oil every 4-500 miles on highway.. seals and rings seem good when I pulled plugs..
question: is there a electrical reprogram for computer? to make electrical random?.. like old NorStar problem of non-random computer program
not on this engine
the plugs do not have anything to do with oil usage
so, was there ever a fix?.. do others have same issue?
please explain....are you talking about it using oil
the computer has nothing to do with it using oil
understand.. but no evidence of hot/dirty cylinder
indicating bad valve seal or piston rings
how long has it been using oil like this
what i had heard was when go on highway and low fuel demand then engine goes down to ~ 4 cylinders to conserve and rings were not hot allowing oil to pass
since I noticed at 56K miles between oil changes as started knocking (low 2 1/2 quatrs).. Isuzu said ok.. did nothing on warranty .. wanted to run cleaner thur for valves.. at 194K and runs great yet but still uses oil and have to watch when on road trips
it has 194k on it now?
just thought they may have finally reprogrammed and fixed issue with variable electrical change .. ie alternating plug charge to level..
yep, still runs great.. change oil every 4K since I've owned.. same characteristics.. never got worse
there isnt really anything short of rebuilding the engine you can do for this oil usage problem
I know/ I know.. count blessings, but don't think rings/seals as characteristics same.. doesn't seem to need a full teardown
what weight oil do you use?
have always used Valvoline Mix blend.. started Valvoline mixed blend 15-40 MaxLife
here is what you can do
above at ~75-85K
remove and replace/clean the pcv valve
tried full synthetic for about 5K and never helped
it may be letting oil to be pulled into the intake
changed PCV at about 185K
can change again
and or/you can ue a little thicker oil[maybe 20w50] to slow down the oil usage
REMOVAL PROCEDURE 1. Remove the vacuum hose at the PCV valve. 2. Slide the clamp back to release the hose.
3. Pull the PCV valve from the rubber grommet in the right valve cover.INSTALLATION PROCEDURE 1. Push the PCV valve into the rubber grommet in the left valve cover.
2. Install the vacuum hose on the PCV valve and secure the vacuum hose with the clamp.
ok.. just trying not to gunk up valve covers with to heavy/surapy (spelling) oil
other than this,,,,there is really nothing you can do.....just keep check on the oil
i would think the problem here is an aligned piston ring..maybe from the factory..
ok.. thanks.. anyway now I know they never fixed issue before they went out of busn
this problem isnt going to hurt it,,but,,it will always use a little oil
check that pcv valve
yep.. have always watched.. better in town driving at ~1200/quart.. highway at 4-500/quart.. so don't drive out elk hunting as cost to much for oil.. ok.. thanks
you are very welcome
