  • trailblazer 302 blown engine

    I am so upset right now. My 302's motor blew up, the con rod of course just like all the other ones. I knew about the issue, I changed the oil with full synthetic every 100 hours a lot of the times it was 90 hours. Changed plugs, both fuel filters, and air filter every single oil change, I went way above what was required in fear of it not lasting. At 1500 hrs it started burning a bit more oil and then got worse. Almost 1/2 litre every 10hrs run time. Took it to a kohler dealer and they said it was normal. 3400 hours it blows up, owned it for 6 years. I paid 4500 canadian and now a new one is $7500!!! Looking for recommendations on what I should do. Buy a new motor and have it installed? If I do that with the generator having 3400 hours on it how much longer is that going to last as an estimate? Couldn't come at a worse time.

    1/2L every 10hrs run time normal?! I'd say that Kohler dealer/tech threw a rod too.

    Are you mechanically inclined? Could likely rebuild the original for less than having a complete new engine installed. That's if itsimply broke a rod and didn't damage the block and other components. I'd run the numbers including having the block bored if necessary.
