January 4, 200422 yr I have the service manual for the '98 DOHC EJ25 I am working on. The section for the cam installation lists the following torque specs: ft-lb : 14.5 ± 1.4 what does the ± 1.4 mean ? Thanks, Rob.
January 6, 200422 yr thats plus or minus 1.4 foot pounds. The amount you can be off and still within spec.
January 6, 200422 yr It's kind of scary that you are working on an engine and don't know what a tolerance number is. I guess I've been around the military too long, and think this is very common knowledge... Tiny

Tiny There would be an awfull lot less hobby mechanics and even less internet resources if people would be scared to try something new. I think the technical term is 'learning'. ;) Rob. BTW, thanks Shawn.
January 6, 200422 yr Sorry, didn't mean to ruffle your tail feathers or make it sound like you shouldn't be learning. I learned just about eveyhting I know by tearing things apart. But by your original post, it seemed you were knee deep into a rebuild, and that's why I made the comment. That kind of info you should know before hand. But, as my dad used to say, if you meet someone that's never made a mistake, you'll meet someone that hasn't done much. My mistake... Tiny
January 6, 200422 yr Originally posted by cookie That had torques like very tight and good and firm listed in the manual. Nice! Honestly.....after wrenching enough, you get to feel what's about right. Normally I'm in the ball park 5-10 ft/lbs if I bother to check myself. Certain things though I will use a torque wrench because they're more sensitive.

Tiny No problem, Tiny. I guess I was a bit hot off the handle.. It's hard to get an 'emotions' reading from an internet post. No harm done, and point well taken Rob.
