potassium 88,,,norm =3!

sodium 216,,,norm=48! should not use salt water huh!!

they say prob coolant, head gasket? not enuf for crack??

CurrySoSpicy

What was your Boron level? Hmmm, well even if it is just a head gasket, you know this forum is going to wag its finger at you if only replace the gasket and put that turd of a head back on top of it.

exactly...if your gonna be down there, just replace the head and you wont be such a worry wart anymore

Used TUPY or new Clearwater cylinder head, couple of frequent oil changes to clean things out. Hopefully done. How is your oil pressure? Coolant mixed with oil can wipe engine bearings in pretty short order.

If the 2000-2001 factory 0331 head comes off for ANY reason, it should never go back on.

1st, boron ,8,,,normal =47...?

jeep runs exactly as it did 6 mo/2000 miles ago. since it has ? piston slap,we think, ill drive it till it blows and put in a rebuilt.oil and temp are stable and good. see what they say about noise??



Thanks for the notes about the piston slap. We're thinking the noise might actually be related to the
coolant that's present. Potassium and sodium likely show the contamination. Antifreeze is a common
problem for this engine - usually it's a head gasket. The good news is, you've caught the problem before it
did any serious damage. Wear looks okay next to averages, which show typical wear for this type of Jeep
after 4,100 miles on the oil. Sodium can also be an oil additive, but in this case we suspect coolant. Watch
for coolant loss and check back in 2K mi.

scuse the mess, best i can do

sorry the numbers dont show from a copy/paste?

btw, coolant goes down VERY SLOWLY,hard to notice

Could be a damaged piston skirt or something like that. Have you had this thing for a while? It's possible a previous owner overheated it and did a bit of damage.

The coolant contamination diagnosis lines up. You could do a leakdown test to confirm. Wouldn't be any harm in dropping the oil pan either and seeing if there are any little bits inside.

Have you used a stethoscope to narrow down the location of the noise? You can get a mechanic's stethoscope for $4 at Harbor Freight. Ticks and noises can bounce around so that it's not clear where they're really originating, but using the probe against the block and head can give you a better idea where it's really coming from.

I was hearing a loud tick that sounded like it was coming from the bottom end. The stethoscope narrowed it to my camshaft position sensor, which just had a loose magnet in it.

nujeepguy

yeah i still wonder if it is something outside. thought of pulling belt for a short test?? see if its something belt driven.
meantime i drive it daily,all gages stable,very slight drop in coolant.
ill get the scope,thought i had one but where?!

fijicorey25

It's similar to my report. I had a cracked head. You're gonna need to replace it at some point. I did it myself for about $600 with all the parts, fluids and miscellaneous items.

Denial.......

I think he's referring to the fact that you have solid confirmation that you have a head problem, yet you're not already making plans to pull the head.

Blackstone said flat out in that report that you have coolant in your oil. There's no way to get coolant in your oil other than either a cracked head or a blown head gasket. The time to fix that is now, before it damages the bearings. It doesn't matter how slowly the coolant is dropping. You know that it's going into the oil, and if it's going into the oil, it is damaging the bearings. When pulling a 0331 head off for any reason, it should be replaced. So just bite the bullet and order a Clearwater head.

The only other factor to consider here is the source of the noise you're hearing and whether it means you need a full overhaul. Either way, you need to do it soon, because continuing to run it like it is virtually guarantees you'll ruin that motor.

BlueRidgeMark

There is another way.

Cracked block.

Occam's razor says it's the head.

extrashaky

Doh.
