antil33t 90 Report post Posted January 7, 2010 When I was adjusting the tappets the other night, I found this a broken rocker shaft bridge? (is that what it's called?) Looks like it was broken off when the head was rebuilt... Would've been nice to know about it tbh. Anyone know if this is repairable? Hopefully this isn't a frequently asked question.

e30ftw 396 Report post Posted January 7, 2010 Thats out of it man, Never seen that happen to an m20 head before. I was going to say, I hope you found that chunk / debris and no damage... But if it was before the head was put on then wow. Quote Share this post Link to post Share on other sites
antil33t 90 Report post Posted January 7, 2010 (edited) Yeah, there was no debris in the head at all. I assume it was broken when the engine was being reassembled. I'm taking the car into the Mechanic to have the tappets adjusted... hopefully that bolt is able to hold the rocker-shaft down.. and I'll pluck his brains on how to fix it..., Edited January 7, 2010 by antil33t Quote Share this post Link to post Share on other sites

antil33t 90 Report post Posted January 7, 2010 I'm gonna email the dude that sold me this motor, and ask him, how the hell he did it. Quote Share this post Link to post Share on other sites
*Glenn* 854 Report post Posted January 7, 2010 Its usually caused when the cambelt breaks or the idiot who dissasembled by knocking out the rocker shafts. I've seen it heaps of times. The bolt he's put in it will now also restrict oil flow inside the rocker shaft Quote Share this post Link to post Share on other sites
antil33t 90 Report post Posted January 7, 2010 The engine isn't in too bader shape like this? (will it last for a while) or should I be replacing it ASAP? Quote Share this post Link to post Share on other sites

*Glenn* 854 Report post Posted January 7, 2010 I'd also be worried about what else has been butchered that you can't see after seeing what they did to the head Quote Share this post Link to post Share on other sites
antil33t 90 Report post Posted January 7, 2010 I'd also be worried about what else has been butchered that you can't see after seeing what they did to the head Yeah, I'm going to email this guy.... and ask him how the hell he managed to break it.. Other than that though it runs fine, Compression tests were pretty good.. all about even. Very annoying, I really can't be bothered replacing the engine again. This just needs to last a while...

antil33t 90 Report post Posted January 7, 2010 Is he a member ?? Nope, I wouldn't think so. He was selling it on trademe, we ended up ringing him, he sounded legit. Is a Diesel Mechanic. Said that he had bought a second hand head, and rebuilt it with new parts (looks clean ect) so it's got a new gasket, cambelt ect. Sounded like a good deal, grabbed it and here we are now.

e30ftw 396 Report post Posted January 7, 2010 I'd be curious to see what the bottem end looks like, If it was this motor that had the cambelt snap , if it was the cambelt that broke it. Damage to the tops of pistons etc. If it were me, I'd probably live with it. It's not like you race, or put this motor through it's paces. Quote Share this post Link to post Share on other sites

_ethrty-Andy_ 2122 Report post Posted January 7, 2010 That looks like the head off my parts 325i. I sold it to a guy not far from me about 8 months ago knowing full well about the head being like that and he said he wanted it for parts anyway. Looks like youve got it now though Quote Share this post Link to post Share on other sites

antil33t 90 Report post Posted January 8, 2010 (edited) Ahh well, I've decided that I'll try and get another head. Can I get a blank head with nothing in it? and swap in my valvetrain... the rockers I have are apparently (and look) new. Just got to find a head is all And yeah, I realise this will require a new gasket, cambelt, head studs ect. Edited January 8, 2010 by antil33t Quote Share this post Link to post Share on other sites
