Here's the head gasket:
B: INSTALLATION 1) Install the cylinder head and gaskets on cylinder block. CAUTION: Use new cylinder head gaskets. Be careful not to scratch the mating surface of cylinder head and cylinder block. 2) Tighten the cylinder head bolts. (1) Apply a coat of engine oil to washers and bolt threads. (2) Tighten all bolts to 29 N.m (3.0 kgf-m, 22 ft- Ib) in alphabetical sequence. Then tighten all bolts to 69 N-m (7.0 kgf-m, 51 ft- Ib) 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 (3.5 kgf-m, 25 ft-lb). (5) Tighten the bolts (C), (D), (E) and (F) to 15 N-m (1.5 kgf-m, 11 ft-lb). n n (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 al- phabetical sequence. CAUTION: Ensure the total "re-tightening angle" [in the two previous steps] do not exceed 180". The lettering for the bolts goes like this in correspondence to your head. C A F E B D |

for the camshaft:
tighten to 16ft.lbs. in alphabetical sequence. Oh and start with the intake cam. I don't know why, that's just what it says. A E C B F D and remember to tighen them slightly before torquing them down. Sorry for the crued figures, but the manual wouldn't let me copy the pictures for some reason. You should be able to figure out which bold is labeled what pretty easily though. |
