Exclamation Replaced head gasket. Still overheating.

I had my uncle do my head gaskets for me in trade for some labor. He said he lost the paper with all the torque specs and head bolt tightening rotations so he just used his own strength to tighten them all down 1 by 1. After completion, the motor is still overheating on me.

Since he didn't use the:

1) Tighten all bolts to 29 N-m (3.0 kgf-m, 22 ft-lbs) in alphabetical sequence.
2) Then tighten all bolts to 69 N.m (7.0 kgf-m, 51 ft-lbs) in alphabetical sequence.
3) Back off all bolts by 180" first; back them off by 180" again.
4) Tighten the bolts (a) and (b) to 34 N-m (3.5kgf-m, 25 ft-lb).
5) Tighten the bolts (c), (d), (e) and (f) to 15 N.m (1.5 kgf-m, 11 ft-lb).
6) Tighten all bolts by 80 to 90" in alphabetical sequence.
CAUTION: Do not tighten the bolts more than 90".
7) Further tighten all bolts by 80 to 90" in alphabetical sequence.
CAUTION: Ensure the total "re-tightening angle" [in the former two steps], do not exceed 180".


could he have damaged the head gasket or left a leak somewhere? He put 5 quarts of oil in last night and now my dipstick is registering 6-7 quarts and the oil is thin.

wtf?

sounds like theres coolant in the oil. if it is a milky color and runny it usually means theres coolant in it. -for future reference, dont ever put anything together unless your 100% sure about it. theres a reason they have a certain sequence they want you to follow

I've done more motor and transmission pulls than I can think of, but I didn't have the time for this one.

Oil is NOT milky, however I've just learned that he didn't put in any coolant in the system, only water.

I figured this was going to be my only choice, I just don't have the free time.

he may have damaged the heads themselves if he didn't torque them down in the proper sequence and/or over-torqued the head bolts.

So is the head gasket ****ed then? Can I pull the motor back out and tighten the head bolts in the correct sequence? I don't have the cash for another set of gaskets.
