Replacing cylinder head on 1986 montero with 2.6 timing chain. just need timing marks and head torque specs.

Install the cylinder heads. Use new gaskets and tighten the bolts, in sequence, as follows:

1. Step 1: Bolts 1-8 to 20 ft. lbs. (27 Nm)
2. Step 2: Bolts 1-10 verify torque without loosening
3. Step 3: Bolts 9-12 to 10 ft. lbs. (14 Nm)
4. Step 4: Bolts 1-8 plus 1 / 4 (90 degree) turn
5. Step 5: Bolts 9-12 to 19 ft. lbs. (26 Nm)

I am assuming that you have the 2.2L OHV engine (most do). If you have a timing chain problem, you may want to think about this....this engine is prone to timing chain tensioner breakage. This causes the timing chain to jump out of time. This will often cause the pistons to slam into the valves in the aluminum head, causing valve damage. If you decide to replace the timing set, insure that you get the chain, both gears, and a new tensioner. Install them and set the timing back to correct specs. THEN, perform a compression check of all cylinders BEFORE attempting to start the car. If there is uneven compression, you will need to pull the cylinder head and have it repaired or replaced before you can operate the vehicle. This is a tricky job. Aluminum heads are easy to warp and/or crack. You will need to replace all the cylinder head bolts when you replace the head as they are special bolts that are designed for one-time use as they have a stretch factor built into them. Remember to use thread sealant on those head bolts that extend into the water jacket or you will have coolant leakage. And most, important, USE A TORQUE WRENCH that is in good working order when tightening the head bolts. Be SURE to follow the correct pattern and torque settings or you will have problems.

Help need torque spec for cylinder head bolts 1986 honda civic dx 1.5 pls...

Hi, this engine uses plated links in the chain to match marks on the gears. See figure and installation procedure below. Let me know if you have any questions and thanks for using FixYa.

1. Install the timing chain by performing the following procedure:

1. Verify that the crankshaft sprocket timing mark is aligned with the mark on the oil pump housing.
2. Place the left side primary timing chain sprocket onto the chain, while aligning the timing mark on the sprocket to the 2 plated links on the chain.
3. Lower the chain with the left sprocket through the left cylinder head opening.
4. Loosely position the left camshaft sprocket over the camshaft hub.
5. Align the plated link to the crankshaft sprocket timing mark.
6. Position the timing chain around the water pump drive sprocket.
7. Align the right camshaft sprocket timing mark to the plated link on the timing chain and loosely position the sprocket over the camshaft hub.
8. Verify that all the plated links are aligned to their proper timing marks.
   

1. Install the left lower timing chain guide and tensioner. Torque the bolts to 21 ft. lbs. (28 Nm).
   NOTE Inspect the timing chain guide access plug O-rings before installing. Replace damaged O-rings as necessary.
   
2. Install the timing chain guide access plug to the left cylinder head and torque to 15 ft. lbs. (20 Nm).
   NOTE To reset the timing chain tensioner, oil will first need to be purged from the tensioner.

1. Purge oil from the timing chain tensioner using the following procedure:

1. Remove the tensioner from the tensioner housing.
2. Place the check ball end of the tensioner into the shallow end of the Tensioner Resetting Special tool 8186.
3. Using hand pressure, slowly depress the tensioner until oil is purged from the cylinder.
4. Reinstall the tensioner into the tensioner housing.

1. Reset the timing chain tensioner using the following procedure:

1. Position the cylinder plunger into the deeper side of the Tensioner Resetting special tool 8186. Apply a downward force until the tensioner is reset.
   

WARNING

Ensure that the tensioner is properly reset. The tensioner body must be bottomed against the top edge of the Tensioner Resetting Special tool 8186. Failure to properly perform the resetting procedure may cause tensioner jamming.

1. Install the chain tensioner into the right cylinder head.
   
2. At the right cylinder head, insert a 3 / 8 in. square drive extension with a breaker bar into the intake camshaft drive hub. Rotate the camshaft until the camshaft hub aligns with the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and torque to 21 ft. lbs. (28 Nm).
3. Turn the left camshaft by inserting a 3 / 8 in. square drive extension with a breaker bar into the intake camshaft drive hub. Rotate the camshaft until the camshaft hub aligns with the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and torque to 21 ft. lbs. (28 Nm).
4. If necessary, rotate the engine slightly clockwise to remove any slack in the timing chain.
5. To arm the timing chain tensioner: Use a flat-bladed prytool to gently pry the tensioner arm towards the tensioner slightly. Then, release the tensioner arm. Verify the tensioner extends.
6. Inspect and replace the timing chain cover gasket and oil seal.
7. Apply a 1 / 8 in. (3mm) bead of sealer at the parting line of the oil pan and engine block.
   NOTE When installing the timing cover, guide the seal over the crankshaft to prevent damage to the seal-s lip.

remember head torqueing is not the same as the way we do it.you need the spec book on that one

looks like there is special sequence to reassemble and tightening, a quick note replace any bolts that have two punch marks.tighten as follows: x x x x x 10 4 2 6 8 x x x x x 7 5 1 3 9 torque all down to 15 ft lbs torque to 30 ft lbs plus 90 degrees. Good luck!
