I'm in the market for an H1. I've seen many posts about the #8 cyl cracking in '98s. Is this the only year with this problem? I have seen several newer models with "new engine"s. I met up with Kevin and his veggie oil H1. Pretty cool idea. He even let me drive it. Thanks!!! I would most likely convert mine to SVO if I got one. I feel I could do the conversion myself with the supplies from goldenfuelsystems. Thanks for any info on the bad #8 years.

There are some trucks as new as "2001 model year" that may be at risk for the cracked block issue; it all depends on when the engine was manufactured.

If the 4th character in your VIN number is a Z your engine was manufactured by GM and is potentially at risk. If the 4th character of your VIN is an F your engine was manufactured by AMG and is the newer design so you don't have to worry.

If you have a GM made engine, you can check the casting number; GM made changes on engines starting with casting # C-159 to resolve the problem, so C-159 and later engines are the enhanced version.

Many trucks with the "Z" in the VIN already have the improved block, but some do not.

Hope that helps...
