What oil brand and weight are you using with hydraulic lifters in 258
A few months ago I replaced a bunch of things in the old 258 including the cam. After researching about breaking in the cam I learned that oils today do not carry the amount of zinc and phosphorus as was needed many years ago for flat tappet cams. I have been through 4 oil changes in the last 6 months and haven't used the same thing yet. I have used everything from royal purple racing to the Walmart conventional w/ comp cam break in additive. What does everyone suggest?
I don't know if there is a "right" answer, but for the last 20 years, Ive been using Valvaline High Milage 10 W 40 in all my stuff. Ive gone over 5 K on many a change with no problems.
Break in oil is always a good idea on new stuff.
The Rotella T6 has been in Grammys CJ almost since the product first came out.
There is a guy or three on the WJ Fourm that ran Walmart supertech in his 4.0 and his wife's and I think a kids............they all had well over 300,000 miles on them at the time he posted. A few others mentioned their really high milage rigs on it too.
I use Rotella T 15w-40 and a Wix 51522 oil filter in my 85 CJ 7. Seems to be a good combination.

I just tried Defy by quaker state without the break in this time because I was getting white foam in the dip stick which I thought was water but now believe to be additive????
I am also getting smoke from the exhaust that will not go away. It only comes from 1st gear out of the gun. I thought it was from the grease and additive from the rebuild of the heads. Not sure on that either though....
This is real foamy though. I dont know if you have heard of this but my hood leaks onto the valve cover. I thought water was getting into the breather hole so I fabricated a water shield for it but I still get white foam.
I also checked for a head gasket leak and was okay in that department.
