Bingo, hondas are all interference engines, (99%)
http://www.interferenceengines.com/honda.html

3.0L J30A1 V6 200 hp (150 kW)??????? this one?
SOHC V6

no compression on all cylinders????????? or just 1.
1: the valves were bent. at the belt snap?, (skipping 60k service !@)
2: you timed the cam wrong.
3 : The system uses the i-VTEC system to turn off one bank of cylinders under light loads
so maybe this feature is active? and you didnt check all cylinders for
compression? ???? try all 6 and post.
did you follow all steps in the FSM to do this job? y/n
or alldata.com ????

4: did you have the HLA valve lifters out. and not prime them? per FSM.
if you like this car, why not own a FSM. (or equiv)

never ever crank over any interference engine after any major work
(heads off, cam belt, change,or lost compression)
until:
1: you turn engine over by hand, sparks out.
2: then run a cyl. leak down test, first. on all 6
if not ,the 7 HP starter can in FACT bend valves.
that be Rule 1. (or $$$$$$$_)

SOURCE: water in cylinder?

If your going to do the work yourself, its not an expensive fix, little time consuming but it you pay attention to the parts when you take them off its not that bad, all in all, should be able to do it for less than a hundred bucks. Gaskets and fluids are all you need.

SOURCE: 2004 Honda Civic Ex won't start

if it sounds like it is trying to start you possibly have the firing order off. if that is not the case I would recheck the timing of belt to make sure you dont have one tooth off. stuff like that is so aggrivating, but if you have fuel and fire all you are missing is compression,if firing order isnt off, valves not being completely closed whent they need to be. due to improper timing.

SOURCE: Determining if head gasket is blown on a 1994 honda accord Ex w VTec

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.

I recently changed the head gasket after overheating. The car is not starting and emitting heavy smoke


How hot did the car get before you had to change the head gasket? If the car had extreme heat then it could have damaged the rings. The rings will collapse and allow oil to squeeze past and burn out of the exhaust causing the smoke. Also since the rings are collapsed the vehicle will have no compression hence the no start. First thing is do a compression check.

low compression can be either leaking head gasket-bad head /burnt valves--piston rings --damaged cylinder wall all of these are a tear apart fix a rebuild depending on mileage and condition of engine a replacement engine might be a better financial solution ---as for weak spark coil --wires-spark plug -fouled spark plug --and if same cylinder as damaged one the compression

I don't see any mention of having the cooling system flushed or the water pump being serviced. Both could be creating your problem. Also are you sure the new head gasket was installed properly, the right one and not upside down.

98 honda accord v6 only has 90 psi compression


90 psi compression is the minumun for gas engine to ignite, you have low compression what is the compression next to it? The compression on Honda V6 is 200psi. you can have a valve problem a blown head gasket, Also make sure your compression gauge is accurate by using another compression gauge

Does bad timing cause head gasket to fail


It is possible that bad engine timing could cause overheating, enough to cause a head gasket failure, but you would notice that happening.

It is also possible that backfiring and engine pinging (which are symptoms of engine timing being out) could contribute to head gasket failure, but again you would notice.

If you have not been aware of these symptoms, or hard starting (the most common sign of engine timing being out) then I think there is no relationship in your car.

In any case if the head gasket needs replacing, part of that job is reassembly and resetting of the engine timing. Ask the mechanic what tests were done to decide the head gasket has failed. These are a compression test, a leak-down test, and looking for water in the engine oil.

If the mechanic has said the head gasket "is failing" I would ask how he knows, because they don't do that imperceptibly, they are either OK, or they leak.

Replacing a cylinder head gasket is a miss or a hit. In some cases, just replacing the gasket may work. But if the cylinder head is bend, dealer may ask to replace it, because "machined aluminum heads rarely works". In this case the cost may be more than $1000. It is a good idea to send the cylinder head for inspection, in a machine shop. They charge $150 for inspecting, checking, cleaning and if necessary machining the head.
If the timing belt will be replaced this is an extra cost. If someone will just replace the gasket, on a bend cylinder head, it is more likely to blow out again. This problem can be solved if the gasket be replaced properly, checking and taking care for the cylinder head too.
As the coolant warms up, it expands and for that reason you have two marks at coolant bottle. Down cold and up hot. It is normal for the coolant to overflow from coolant bottle, if it is filled to the upper mark with engine cold, way up the cold coolant mark. Let engine to cool down overnight and set the level at coolant bottle at the lover mark cold. If it will overflow again this is a bad sign. The pressure at combustion chamber varies from 75 in idle up to 150 or more in higher RPM. If the cylinder head gasket is blown, then gases are blown into the cooling system, increasing the pressure, the radiator cap pressure relief valve is open and coolant is discharged in the coolant bottle. In such cases it is common for the coolant bottle to boil. You can observe gases discharging in the bottle, mixed with coolant, from the cooling system. These are symptoms of a blown cylinder head gasket. Because you replaced it once, there might be a bad (bend, deformed) CYLINDER HEAD too.
To find it out you have to perform cylinder compression test on your car (PROFESSIONALLY).
1. Start with a normal ("static") compression test. To eliminate rings, valves, holes in pistons, that sort of things. A normal cylinder balance test is also helpful (so you know which, if any, cylinder is presenting a problem). Engine should be warm.
2. Put all spark plugs but one back in. Ground that plug wire to prevent module damage. Disconnect that injector on a port fuel system.
3. Put your compression tester into the empty hole. The test can be done without a Shrader valve, but most people recommended leaving the valve in the gauge and "burping" the gauge every 5-6 "puffs".
4. Start the engine and take a reading. Write it down
5. Now goose the throttle for a "snap acceleration" reading. Reading should rise. Write it down NOTE: Don't use the gas pedal for this snap acceleration. The idea is to manually open then close throttle as fast as possible while without speeding up the engine. This forces the engine to take a "gulp" of air.
6. Now write down your readings for at least the bad cylinder (if there is a single bad cylinder) and maybe 2-3 good ones. Make a chart like this: CYL STATIC COMPR IDLE -RUNNING COMPR - SNAP Cyl 1 150 75 125 Cyl 2 175 80 130 Cyl 3 160 75 120 Cyl 4 160 80 125
7. ANALYSIS: Running compression at idle should be 50-75 psi (about half cranking compression). Snap throttle compression should be about 80% of cranking compression.
Consult a professional with the readings. If the gasket is to bad, you may have very low compression at lease in one cylinder.
If you will get a positive confirmation for a bad cylinder head then you have two options:
REBUILD THE CYLINDER HEAD or REPLACE IT.

Engine light wenton, car heated up, car would not


If the engine overheated while driving, damage to the cylinder head gasket or engine block/cylinder head may have been done, which would prevent the vehicle from starting.

A standard engine compression check will tell the tale.

A compression test would be the next best thing because if you are sure that it is engine oil in your antifreeze then it could be a head gasket, but it you don't get a bad reading from the compression test then it might be a intake gasket

How to test head gasket (non running engine)?


Yes, remove all of the spark plugs, and test each cylinder individually. This will tell if the gasket has sealed properly. Once you get the engine running, do this again to see if it can hold combustion pressures.
