Everything looked great till I removed the front main bearing cap. Is this a common fault? Has anyone had this before and what would cause the main cap to break? It's not a fresh crack so I was racing this way.....time to buy a lotto ticket? Dragged a spare engine out from the engine shed and will send it to the machine shop on Monday. <div>I checked a few other mains and nothing I have lines up close enough to line hone ...also a Triumph thing? <br clear="all"><div><img src="cid:ii_lsrk43wn0" alt="image.png" width="452" height="293"><br></div><span class="gmail_signature_prefix">--Cheers!!!</span><br><div dir="ltr" class="gmail_signature"><div dir="ltr"><i><font face="comic sans ms, sans-serif">Mike Deweerd</font></i></div></div></div></div>
