2000 Z28 engine replacement

[PeteLeathersac]

Here's my 2 cents Canadian. . Since you use it little, I'd leave well enough alone. . Nothing against your dealer but some monkey-techs could cause a whole lotta' bad to a nice car? . Paint damage from the re & re, a/c and other problems come to mind? . Adding less than a quart of oil per year using your averages and having an unmolested engine compartment is better. . Who's to say the replacement engine wouldn't turn out the same anyway?? .

I'd definitely keep the old engine in the car and run Shell 15w40 Rotella oil. It's a little thicker and might reduce the slap and the consumption problem. Having the original engine is definitely a plus in my book. In 20 years the car will be worth something. If you want something to compare to valuation-wise, look to the 20 year old IROC Z28s and see the major price difference between one with it's original engine and a replacement. It's as much as a 50% difference in value. Just my 2 ruble opinion
