<p>[QUOTE=&quot;rte, post: 26069943, member: 78199&quot;]I figured out the issue. Timing belt slipped or jumped a few teeth out of time.</p><p>The cause of that was the bolt on the tensioner pulley came loose.</p><p>It came loose because someone at some point overtightened it and it started to pull the threads out of the aluminum head.</p><p>I was able to get a longer bolt and catch the rest of the unused threads in the hole.</p><p>It started but has a top end rattle... thinking valve train noise.</p><p>I have a video and was going to ask my neighbor for a second opinion before I tore into it further BUT I couldn&#039;t catch him on Sunday.</p><p>I tore into it Monday afternoon as I had a few hours of free time.</p><p>I&#039;m at the point where I can check the valve shim lash.</p><p>My neighbor listened to the video but said he couldn&#039;t tell, would have to listen to it running.... I&#039;m thinking now that I might have jumped the shark and done more than necessary but I&#039;m learning and can put it back together if I don&#039;t find anything with the valve lash clearance test.</p><p>Should know more today as the spark plug wires came in yesterday and I was able to get the broken boot out of the #4 plug tube...so making progress, but probably didn&#039;t need to pull it this far apart and made extra work for myself.</p><p>That&#039;s how we learn sometimes.</p><p>Thinking it could be as simple as the oil didn&#039;t get up to lubricant the valves from sitting? I figured I had turned the motor over enough to get the oil flowing but the top end was still rather dry.</p><p>I&#039;m erroring on the side of caution, because I haven&#039;t messed with this motor this deep.</p><p>The rattle I wasn&#039;t expecting and honestly it TILTED me a bit... Toyota motors are usually really quiet.</p><p>I&#039;ve had a few and never had a valve lash clearance issue...it&#039;s a combination of I don&#039;t know, I haven&#039;t seen it yet and I didn&#039;t wait for a second opinion.</p><p><b>I only have an extra $35 in it so far and that&#039;s what I needed in parts to replace anyway to make it work or run.</b></p><p><b>[ATTACH=full]1660111[/ATTACH] [ATTACH=full]1660112[/ATTACH] </b>[/QUOTE]</p><p><br /></p>
