Need Advice: Oil in Radiator :-( When i changed my head and head gasket on the passenger side I torqued it down with 3 passes going up to 65 ft. lbs according to the haynes manual. But when I read on the internet everyone was telling me to do 125 ft.lbs(or somewhere around there i forgot the exact number). What torque specs am I supposed to use? The car ran "okay" with no head gasket leak, but did have an oil leak due from not being correctly sealed at the rear of the intake manifold, it was also missfiring. occassionally the car overheated( i did not let it get past the 3rd tick) but i figured it was due to not properly bleeding the radiator system so i just kept filling it up with coolant thinking the airpockets would soon bleed out by me filling everytime with the car running and bleeder valve open, and i ran like this for maybe less than a month. then the other day i opened the radiator cap and found "chocolate milk".

And if i were to do them again, would i have to remove the head gasket and get a new one or could i just re-use them and unbolt the headbolts, buy new ones and torque them down.

I really hope this is a joke. Why don't you go ahead and post your source for the 125 ft lb torque spec on head bolts.

Verdad Gallardo EDIT : Wife was trying to relay my message so im on here now to fix what she said. The most ive ever torqued an LT head down was 80 ft lbs . Not 125 like previously stated . My apologies for letting someone type under my screenname .
There is absolutely NO WAY you should be torquing your head bolts to 125 ft. lbs. That is ridiculous advice. Get some ARP 134-3601s and do them in 3 passes. 25#, 45#, then finally 70#.
What testing have you done to come up with this torque spec that will pull the cylinders way out of round if the bolt doesn't strip or break? I guess I shouldn't have trusted arp's torque spec of 65 ft lbs when I did my heads? And if you are using stock bolts the correct way to torque them is with an angle gauge not a torque wrench.
You are telling someone to torque his heads to TWICE the torque spec. Think about that for a minute...

i want to see you torque the head bolt down to 125ftlbs then take a pic of the threads in the block, or the block itself, or the bolt itself and show me the twist in the bolt.. thats near dbl the torque needed..
in my life i have never heard of anyone torquing a head bolt to 125ftlbs.. hell a bigblock head isnt torqued that high.. ive built a few engines in my 20+years of hotrodding and i've never seen a headbolt on any engine needing 125ftlbs of torque.. off the top of my head,if i remember correctly a big block head torques down at 75ftlbs..
