Help!
I have adjusted valves before, just not on this car. I watched Eric’s video on the J Series Acura, then dove into this car. I used the proper feeler gauges and thought I had it right. Went through all the valves twice to make sure I had it right. I made sure the feeler gauges had some drag and tested it against the next larger feeler gauge: If the next larger size did not fit or was tight getting it in there I figured I had them right.
Anyway, started the car and got a high idle because I forgot to plug in the rocker arm control connections. Plugged those in and it sounded great, just like a sewing machine. Drove it two blocks and it died when I hit the gas. Waited a minute and started it. I would idle but not accelerate – it would just die upon hitting the gas. It did that a couple of times. Now it wont start at all.
Are these valves too tight? I have never owned a car that would not at least run, even with Zero clearance. What have I done wrong? Please help, thanks.
By the way, there is very little room to even fit the feeler gauges inside these heads. I figured after I got all the stuff off the top of this engine that valve adjustment would be the easy part. It was not!!

I am guessing you have something unconnected . Vacuum or electrical / electronic .
Timing belt or chain ?
How many miles ?
Go back to basics . air , fuel , spark .
God bless
WyrThat’s what I thought too. But i have been through the car several times and cannot find anything more unplugged or disconnected. I replaced the timing belt two weeks ago and it was running fine.
Will tight valve clearances cause this Honda to not run or start at all?? What concerns me is the progressive nature of this. First running fine, then quit and running at idle only, now wont even start. Weird.
Do not know about the clearance stopping the engine from start / run .
How many miles ?
God bless
WyrI suggest you order a Haynes & Chilton manual . Rockauto.com shows to have them in stock .
Check on youtube for more information .
God bless
WyrThank you. The car only ran for 5 minutes before dying, so unless those valves are plastic I don’t think they have burned yet.
This is a V-6 ?
You adjusted the valves on both banks ?
It appears to have a variable cam system .
If so , can you tell if it is OK ? I think , typically , these systems use engine oil pressure as a ” Hydraulic Fluid ” , to operate the mechanical part of the system .
If this is a V-6 , overhead cam engine , there may be 2 of these systems . One on each bank / head .
I think there is a TDC sensor , possibly a crank sensor & a cam sensor or sensors ?
God bless
WyrIs the engine getting air ? Is the throttle body / throttle plate mechanical or ” fly by wire ” ? Is it opening ?
Are you getting spark ? Plugs , wires , coil / coils OK ?
Is it getting gas ? To the fuel rail ? To the injectors ? Electrical to the injectors .
Try giving it a small dose of your favorite priming fluid . Did that help ?
God bless
WyrHi Wyr
Yes, it is a V6 3.5 liter J series engine. I adjusted valves on both banks,
all 24 valves. The rocker arm control for the variable cam timing is
on Bank B (cylinders 1,2 and three, in back as you face from the front of
the car. There is no control on Bank A.I just went through the whole engine again and cannot find anything unplugged or amiss. I just tried to start it again to no avail. I pull
ed two plugs immediately after and found them dry, so I’m beginning to think it may be a fuel delivery problem, although I never touched any of the fuel system components, electrical or otherwise. Checking the fuses now.Is the throttle plate opening , admitting air ? If so , squirt a tiny amount of gas or something equally combustible , past the throttle plate . You could even take a hand held propane torch and give it a whiff of propane ( with the throttle plate open ) .
Did you disturb the intake manifold ?
God bless
Wyr[quote=”Mahat” post=186384]The throttle is fly by wire and I cannot tell if it is opening.
Plugs are new. Coils are fine.[/quote]Just guessing , but I would remove the air duct / hose from the air filter box to the throttle body . So you can see the throttle plate . Have an assistant turn the key on , but so not try to start it , yet . Have them depress the accelerator petal . Did the throttle plate respond / move ? If not , try the same thing while cranking the engine .
Does it haVE A FUEL RAIL ? dOES THE FULE RAIL HAVE A SCHRADER VALVE ( looks kind of like a valve stem on a tire , but all metal ) ? If so , you can use it to try to measure fuel pressure .
I do not know what normal fuel pressure is , on that engine ? Maube some one else can chime in ?
God bless
WyrI think you may be onto something, Wyr. I didn’t see a schrader valve. But I just squirted some starting fluid behind the throttle plate and got it to turn over. Unfortunately, I’m by myself and nobody is around right now to help me inspect the throttle plate, but I will look at it as soon as I can.
If it is the throttle actuator, I’m wondering what I could have done to damage it? I left it on the plenum when I did the valves I only unhooked it from the air duct and unplug it from the wiring harness and both were back on tight. Besides that, it did run and accelerate a little just before it died. Strange…
