Re: 2000-2001 owners, chime in...0331 head
Get a 99. Skip the 00-01.
99s have more power and get better mpg. Don't crack heads, have better front diffs.
My second choice 98
Then a 00-01.
If you want to get crazy like supercharger/turbo/stroker, I would do a 97-98 as the PCM is a little dumber.
The issue isn't just that the head cracks, it's that it lunches the whole engine. For the most part they barely seep fluid, not really leak, so most people won't notice the loss of coolant. The quick lube place tops it off every 3k which doesn't help.
Most of the time what I see Is customers bring it in for little or no oil pressure. One look under the oil cap reveals a sludged up mess of coolant/oil mix. Coolant doesn't make a good lubricant for bearings.
If you find a good deal on a 00-01 that you can't pass on, check under the oil cap for sludge, then if it looks good and you buy it, shop around for an 03 and newer head to swap on.
