I retorqued my T/D today, I pulled it to 100 on a fiber gasket with the ARP 12 m/m studs,I initaly did them at 80 when I put it together and then 85 after it ran a few times, maby a total of 20 minuets at that time. Also did it cold then too. I couldn't realy say any fealt loose but I just went to 100 1 at a time in the right sequence. My uestion now will retorquing change the timing? I saw this on a post the other day and thought the person was joking But I can tell you this engine does feel like the timing has changed as doesn't have the zip it had yesterday and idles slower also, smooth on all 4 like before but slower and not quite the same pick-up as before. I can't imagine just pulling the bolts a little more snug could change that, It's not like the head went another 1/4 inch down or something which I could possibly understand, just a microscopic amount if even that. It is definately a little slower though and does idle slower when warm than before and it sure feels like timing to me. Every cylinder feels equal and none miss or stumble, could it actualy have changed time at the pump, seems unlikely to me but thats just what it feels like.
