dump the multi grade
put in straight 30wt

 

How many miles is equal to 5 quarts of oil consumption? There is no way to burn that much and not notice some smoke.

 

goochie: Are you sure about that? That's almost a qt a day. And NO leaks?

Mine uses about 1/4 cup in 3 months--and it's hot here.

 

A late model 231 or 3.8 liter buick V6 will drop right in. I think older even fires will also. you will need to use 2 225 short water pump and maybe grind a bit on the nonsealing surface of the manifolds to allow sealing. A 225 would probably be stronger. AM

 

leaking somewhere..............or bug spraying!

 

ok just added more oil i check it quite often was a few days and heard lifters so i checked the oil 3 quarts low barely on dipstick added oil again now it seems to have slowed burning or whatever it is doin there r no oild spots where i park unless it leaks only when drivin i do see some blue smoke at start up but otherwise no burning and oil dont smell like gas as far as another 225 hard to find parts for this one couldnt imagine where to find another one anyhow without drivin 500 miles junkyards around here have no jeepsi dont see alot of oil around valve covers or on bottom of oil pan either it is weird like lookin for a needle in a haystack

 

[ I just wonder if the fuel pump is leaking into the block and diluting the oil. When you check your oil have you noticed it smelling like gasoline?[/quote]

If this were the case, wouldn't the dipstick show over full?
Oil must be going somewhere. How's the PCV valve, breather on the valve cover if you have one? I had a truck that was losing oil and the tailgate was spotted with it. Rear main was gone and entire undercarriage was coated with oil.

 

check radiator.............might have cracked head.

 

cant figure it out

like i said oil dont smell like gas and radiator is still full ang green not losing it there it doesnt seem to leak at idle or parked so i gotta believe it is being lost goin down the road somehow but underneath of jeep is dry and clean also i just got a new paintjob on it and no spots of oil on it either once i get a digital camera i will post some pics it is lamborghini green painted the hubs and lock outs green too black rims and black wall tires plan to have a buddy make me some flamed vinyl graphics to put on it too any way doesnt seem like it does it all the time eiother cause sometimes i can go a week without adding but this last week it seeemed to eat as much as i could feed it but the last few days it is holding its own

 

May be someyhing little like a stuck PVC valve?

 

You might consider the front seal on the crank. I bought and subsequently drug home a tired 67 V6 from Colorado in 92. I drove it for 6weeks in Co. Never used any oil. I never got the rpms up very high as it had a bad tire and wobbled like mad if speeds exceeded 45 mph. I towed it to Cincinnati and then drove it to Toledo - some 200 miles. I had replaced the bad tire. I ran 65 mph all the way and axles were 4.88 so I was running some high rpms. Pulled her in and shut her off. Checked oil next day and couldn't get a stain on the dipstick. It leaked terribly out of the front cover at high rpm. Thankfully, I did not blow the motor. AM
