Thanks for using FixYa.

To install:

1. Install a new head gasket on the engine, making certain it is positioned correctly. The cylinder head dowel pins and the oil jet must be in place. Refer to the illustrations if necessary.
2. Install the head. Lower it straight down onto the block, aligning it correctly.
3. Apply clean engine oil to the bolt threads and the contact face of the bolt head. Install the head bolts finger-tight.
4. On all models except 1988-89 DOHC Prelude and 1992-95 Preludes with 2.3L and VTEC engines, tighten the head bolts following sequence A. On 1988-89 DOHC Preludes, use sequence B. Use sequence C on 1992-95 Preludes with 2.3L and VTEC engines.
   1. On 1984-89 Accords and 1984-91 Preludes, tighten the bolts in two passes. The first pass should bring the bolts to about 22 ft. lbs. (30 Nm). On the second pass, tighten the bolts to their final torque of 49 ft. lbs. (68 Nm).
   2. On 1990-93 Accords, tighten the bolts to 29 ft. lbs. (40 Nm) on the first pass, 51 ft. lbs. (70 Nm) on the second pass, then tighten the bolts to their final torque of 78 ft. lbs. (108 Nm).
   3. On 1994-95 Accords and 1992-95 Preludes, the bolts are also tightened in three passes. Tighten the bolts to 29 ft. lbs. (40 Nm) on the first pass, 51 ft. lbs. (70 Nm) on the second pass, then tighten the bolts to their final torque of 72 ft. lbs. (100 Nm).

5. If applicable, assemble the intake and exhaust manifolds to the head. Use new gaskets.
6. If applicable, install the cam, rockers and camshaft holders.
7. If equipped, install the EGR crossover and air suction pipes.
8. Connect the exhaust pipe to the manifold using new nuts.
9. Install the timing belt.
10. Install the valve cover.
11. Install the cylinder sensor (if equipped) and the distributor.
12. If applicable, install the alternator.
13. Install the power steering pump, then connect the inlet hose to the pump.
14. Install the accessory drive belts. Adjust the belt tensions.
15. Install the heater hoses.
16. Install the cruise control actuator if it was removed.
17. Connect the spark plug wires. Connect all the wire harnesses and vacuum hoses to the cylinder head, intake manifold and throttle body/carburetor.
18. Connect the throttle control cable and/or accelerator cable at the throttle body.
19. Connect the fuel lines.
20. Install the brake booster, PCV and charcoal canister vacuum hoses.
21. Install the air cleaner and intake duct.
22. Refill the engine coolant. It is recommended that the engine oil be changed whenever a cylinder head is removed.
23. Connect the negative battery cable.
24. Start the engine, allowing it to idle. Bleed the cooling system. Check the work area carefully for any signs of fluid leakage or any indication of the timing belt rubbing or slapping the covers.

On 1990-93 Accords, tighten the bolts to 29 ft. lbs. (40 Nm) on the first pass, 51 ft. lbs. (70 Nm) on the second pass, then tighten the bolts to their final torque of 78 ft. lbs. (108 Nm).

The Head bolts are located below the cams, so you have to take the cams out to get to the bolts.
The torque specs for the head bolts in sequence is 20, 40, then end at 63ft lbs. Be sure to apply anti sieze or dip the head bolts in oil, before you torque them down or you might pull out the threads. (Not a good thing TRUST ME!)
Hope this helps.

I have a 1998 Honda Accord EX. I had the check engine light come on as well and I had the code read by PepBoys. The code was:P1259 or VTEC SYSTEM Malfunction.
I Don't know jack about were to start to fix this problem, so I bit the bullet and took the car to my Honda Dealer. The problem was checked out and was told this.
( REPLACE VTEC VALVE ASSEMBLY)
I had them do the work because I dont know how to do this. So after $204.00 in Labor and $162.29 in parts, for a grand total $366.29, The car was fixed!!!!!!! Run's great and no check engine light on anymore. So to help you out as best I can, here is the numbers that are on my work sheet. I dont know witch numbers represent the part number but this is how it looks on my paper.

1 15810-PAA-A02 8108797-90870 VALVE ASSY, SPOOL $150.75

1 15825-P0A-015 8161598-15999 FILTER, SPOOL VALVE $11.54

There you go! I hope this gives everyone a place to start. maybe get your self a Haynes Repair Manual (#42014 is for the 1998-2002 Honda Accord, all models) and try to do the work your self. Good luck to all of you form Donald M. in SoCal.

White smoke out of the exhaust is one indication that the head gasket is blown. Another is to start the car and check the oil on the dipstick. If it's frothy or looks like a milkshake, this is another indication of a blown head gasket. The milky appearance indicates that coolant is in your engine, caused by a bad head gasket. If none of these symptoms occur, then the problem lies elsewhere. Hope this answers your question and feel free to post back with any other concerns or questions. Thank you.

start in middle and work outwards left right left right with the bolts ,torque ??easy start with a rachet which will allow about 40lbs then a snap on knuckle bar till you can feel bolts stretch.as to type of head???is it 8 valve or 16??16 valve dearer to do
