I made a massive spreadsheet of every reciprocating component and all possible causes of ticking. I got through everything on my list that didn't require pulling the engine or heads. Bottom line, none of those things were the cause of the ticking. Crap.</p>
<p>Now I have to pull the engine to continue my search. But thats a post for another day. <strong>Spoiler alert, I can see that cylinder 3 is galled and I believe the piston is slapping.</strong></p>|||
