  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

Connecting Rods, you Say...?

Hi All- the other day someone "gave" me a 90,000+ mile 2010 2.0T motor... because it had broken a connecting rod and thrashed the block....that is all I know of the motor's history. I took it apart to "see" what happened. Near as I can tell, the #1 rod broke in two- like a piece of hard candy- and the shrapnel destroyed everything near it. Interestingly- the Main and Rod Bearings were in perfect condition, even the broken rod, still on the crank throw, had perfect bearings in it. The 3 surviving pistons were good, straight, and within spec for the bore diameter. Here's the kicker: 2 of the 3 surviving rods were bent! looking at the beam from the side the bend is visible to the eye. Comment: Apparently the early 2.0 motors used 'powdered metal" rods, and later Hyundai went to "forged" rods for their stronger, more performance-oriented characteristics... My question is: Does anyone know for sure if the later motors indeed use forged rods, or did I just imagine hearing or reading this...? If they do use forged rods- does anyone know WHEN they changed over? I own a '13 2.0 and this is making me uneasy... if you know what I mean...! Put on your Thinking/Informed/Researcher Hats, Folks Thanks! E
 
Yeah the 13+ rods are much better. However, the BK1 intake manifold is metal, not plastic like in BK2 and it can be ported and polished. That is a decent swap since you have one for free.
 
Hi guybo- 2 questions- 1) what makes the 13+ rods better? material, construction, architecture, dimensions...? 2) will the earlier aluminum intake manifold interchange or "bolt on" win place of the plastic one I have in my '13? Thanks
 
The newer rods are forged not cast. Or semi-forged anyway. A lot less BK2 rods turn into window-makers.

I'm not sure how the BK1 intake mani fits. Over at Genesis Coupe.com there's a few people who have done it, ask there.

Decent swap but a little more susceptible to heat soak. I'd go with a phenolic spacer too
