I am working on an 01 Mitsubishi eclipse 2.4 sohc, one intake valve was bent. I did a valve job on it and now putting the head back on, I ordered new head bolts and an upper gasket its a 10 bolt head. I started by tightening the 2 middle bolts down to 58 ft PDS and in a criss cross pattern finished the rest. I then loosened them all up same pattern, tightened to 15 ft PDS and a quarter turn same pattern, went back tightened them up another quarter turn. So I want to make sure the head is torqued down to what's it suppose to be. I have googled and you tubed I keep getting 72- 80 ft pds . So what is the exact torque after all the steps suppose to be? I want to make sure its at the right torque.

Inside to outside for torque pattern, 7 foot lbs. or 144 inch lbs.

There likely is a spec for oil pan but unless you are a finatic, you really don't need to know what it is. Simple rule: Don't crank down ******* any fastener. If corners near crank ends have larger fasteners, you can tighten them a bit more than on siderails. Before tightening anything, install all bolts finger tight, to ensure that they are not cross threaded. To avoid warping pan, tighten from the center of the pan, working towards both ends, alternating from side to side as you go. When you are finished, go over it again, using the same amount of force on each bolt. As I said, end bolts can if larger in diameter, be tightened more but be careful not to tighten so much that you will either split or push the gasket out the sides.. Anywhere two gasket ends **** together, I recommend using a sensor -safe dab of silicone. An oil pan is not under any mechanical stress or pressure. I have used this method for many years and NEVER had one leak. If you really need #s, small fasteners get about 12-15in lbs, larger ones about 20.

The following is verbatum from the mitsu engine overhaul manual... Steps 7 and 8 are a bit cryptic, but it seems like after you tighten the bolts to 20nm in the CORRECT PATTERN... you then go around tightening 1/4 turn through the pattern, then a final 1/4 turn through the pattern... do NOT tighten each bolt to 20, the 1/4 then another 1/4 before going to the next bolt, the idea is to get EVEN tightening across the head, so tighten her three times around the pattern! Now for the verbiage from Mitsu's overhaul manual...


(1) When installing the cylinder head bolts, check that the
shank length of each bolt meets the limit. If the limit is
exceeded, replace the bolt. - Limit: Max. 96.4 mm (3.79 in.)
(2) Install the washers.
(3) Apply engine oil to the bolt threads and washers.
(4) According to the tightening sequence, tighten the bolts to
75 Nm (54 ft.lbs.).
(5) Loosen the bolts completely.
(6) Torque the bolts to 20 Nm (14.5 -ft.lbs.)
(7) Tighten the bolts l/4 turns (90”) more.
(8) Tighten the bolts l/4 turns (90”) additionally.

Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:

1. 20 Nm (15 lb-ft).

1. 40 Nm (30 lb-ft).

1. 50 Nm (37 lb-ft)

• Tighten to 40-50 Nm (30-37 lb-ft).
• Rotate an additional 175-185 degrees.
• Go to next bolt in sequence.

• Tighten to 20-30 Nm (15-22 lb-ft).
• Rotate an additional 175-185 degrees.
• Go to next bolt in sequence.

The gasket has metal torque limiters.use your own judgement just dont break the bolts
