Just find a good donor crank.

Exactly. You can't get a monkey to use emory cloth on a crank for $100.

I don't know exactly, I didn't take it apart. Possibly the filets being cut incorrectly? I'm not sure. It went across the country with a car I sold, the bearing spun in Pennsylvania. Personally, I think the new owner didn't check the oil and he knew before he left that it was leaking a bit, but I remain a bit superstitious none the less. There were a lot of spun bearings all over the country at the time and a good percentage were knowledgeable builders who turned their cranks. Basically, for the same money, I'd rather have a good polished one than a turned one.

I know where you can get a good 2.4 shortblock core for around $350, but it's a bit of a drive.

I got the crank that's been in my car for about 13,000 miles for $75. It was like new, and had never been turned. You just need to know where to look.

Hahahaha.

I was so suprised when I asked an engine builder about how polishing is done, he said just some 600 grit. I couldn't believe it.

I bought a 6 bolt 2.4 long block for $150 from a junk yard. Raptor mike said it was the nicest 2.4L he had seen hahaha. 7 bolt 2.4Ls are all over. 6 bolts are out there too..

Re: experienced engine builders only.
 

I bought four of them, had them sitting on a pallet for months. That's back when "Powderblastco" was building the 2.4's for a lot of people. Finally just sold them all off for whatever I paid. There's a guy in Duluth doing the same thing right now, they're out there.

I think CSS only charges around 110 for a basic grind, I Paid 205 for a grind and they filled in and reground one of the journals, that also came with acls to match the grind.

Thanks for the info, once I get the old crank out, ill know what to do from there. Got my 2 weeks national guard drill thing coming up, i hope I can get it pulled before then!

Re: experienced engine builders only.
 

It never really got stated, but using a reground crank without renitriding usually causes problems. I would agree with the above and find a good used crank that just needs a polish.
