Well, just after the rebuild on my 2.0 liter, I get to enjoy the lovely sound of a stupid knock. I got home a little while ago and my dad said he heard some popping like there was a miss. I told him I didn't hear anything and pretty much thought nothing of it. Well I just went back outside to start it up again and see if I heard the popping he was talking about. And what do you know, a god damn knock is there. Definetly sounds valve related again, but I'm hoping to god it isn't anything bad that would cause a shitload of damage again. Is there any chance that I could be lucky and it's just like a loose valve for some unknown reason? I mean is there anything it could be besides a f-ed up valve that's hitting the piston and is threatening to the well-being of the motor? Please let me know. If this is a problem that's going to involve money to fix, there goes my car!

YA know there could be a bunch of things. Like Dave said parts CAN be bad out of th box. That's why the good engine builders check and measure shit before builind up an engine the final time.
Measuring valve springs is always good. mocking up a motor and measuring clearance/ interferance IS REQUIRED. Not that you didn't do this but ....... Knocks can happen. Check the easy stuff 1st even if you are absolutley positive you think it's good. an exhaust leak at the head can be loud or just a subtle wierd sound. got a exhaust stud not pulled up tight? only takes one. |
