Message: [QUOTE="firehunter, post: 1135928, member: 1162"] I haven't had a mechanical fuel pressure gauge on mine. I am using the "middle " spring that comes with the FRx which is supposed to yield 61-65 psi. I am thinking hard about injector torque and "re-torque". I had one come loose while pulling a grade and burnt up the copper and lower o-ring but I was able to shut it off before any other damage was done. After re-ringing the one injector I checked the torque on the rest on that bank and they were right at the number (120 in/lb) but no more. After reading this from SWAMPS... ...I decided to put a quarter turn on all the bolts anyway. I only had the one valve cover off so I only did that side. I did the other side (bank) today, same results. All were at torque spec, went ahead and put another quarter turn on them. Started noticeably more crisp but I wont have a cold start on it until tomorrow. [B]Got me to thinking...when the engine/cylinder temps warm up and the various metals expand at different rates, does the injector torque get tighter, looser, or stay the same?[/B] I ask because my "loose" injector didn't show up until the engine was pushed hard up a long grade for several minutes meaning it was the absolute warmest it had ever been since this injector install. All temps (oil/water/EGT) were perfectly normal. More curiosities. Inquiring minds want to know... :thumbsup: [/QUOTE]
