Yes. It's the snowball effect, if I do that might as well do this. If I do this might as well do that. Oh and while I'm in there I should probably replace that etc.

 

I have a horrific amount of blow by. At least horrific to me. According to some people here (one guy said he was losing a half quart a week) not so bad but the ocd part of me finds anything more then a drop of oil a week unacceptable. My 46 year old 289 doesn't even come close to the amount of blow by my jeep has. I cleaned the baffles and the ccv vacuum line and put a new oil filler cap on it. That's why I was thinkin about throwing rings on it.

 

Is it blowby as in crankcase pressure or just oil in the air filter?

Here's why I ask.



Cruiser’s Valve Cover Mod
Most early and even later Renix 4.0s could be bothered by excessive oil in the air cleaner box. A fix from my old days as Service Manager at a Jeep dealership follows. Information was provided to me from a buddy at JeepTech during those days. I don’t believe it ever came out in a Technical Service Bulletin.
　
Remove the valve cover and turn it over. Next, remove the fluted tubes that are now facing you by removing three screws on each. Chop 1 inch off each of them. Then, about a half inch up from the area where you just sawed them off, drill a half inch hole in the tubes so the holes will face the rear of the valve cover. Clean and de-burr/sand all rough edges nicely, clean with solvent, and reinstall. Don’t be concerned about the chintzy gaskets that will probably crumble into oblivion when you remove the fluted tubes. They can go back together without gaskets.

 

Ok its oil in the air box but when I hold my finger over the end of the ccv tube to the airbox there is pressure. Seems like this should be normal as I know there is no way the vacuum side will actually cause a vacuum but I figured it was the reason for the oil in the air box.

 

And your CCV hoses/tubes/orifices are clear?

 

Yes

 

Do you use oil between changes?

 

Very little

 

Probably don't need rings then. The valve cover mod may work for you.

Still thinking of changing the oil pump and checking the bearings?

 

Yes. Need to fo pan gasket and rear main.

 

Perfect. Get the FelPro one piece pan gasket then.
New oil pump for sure?

 

Ya might as well while I'm there.

 

High volume or no?

 

No just stock. You think I should go high volume?

 

Price them out and decide for yourself.

Many times a Melling HV pump with new pickup is about $3 more than a stock pump with no new pickup.
