Heres the problem, motor HITS vtec, can hear it audibly, 70psi of oil pressure AFTER the vtec solenoid so there enough pressure. Solenoid is working properly, not clogged or anything. Car holds boost , no boost leaks (9psi)

Car hits vtec and falls on its face. This is a brand new Honda head, that the customer had smoeone else assemble it. Im thinking the rocker arms are only engaging on certain cylinders. only thing i can think of.

 

Check cam timing?

 

Cam timing is SPOT ON

 

I had a similar problem with a car, and the intake cam was retarded a good bit. That is all I can say from a personal experience. Hopefully it is something dumb like that and not internal.

 

You definately have a problem if that is your dyno graph

 

I have seen similar graphs when the timing belt is a tooth off.

whats the gap on those plugs?

 

I have had timing off a tooth and never had a motor react like this. I think it's internal.

 

whats the compression test results?


i would assume the car drives and idles fine....all is well...then once you hit vtec it feels like a turd? does it break up and buck and sputter and ****....or just not make any power...sometimes the graphs dont completley resemble how the car "feels" on the dyno

 

mine dod the same thing, as far as power, intake cam was reatrded 10 degrees. cam gear bolts slipped.

i know you said you checked the cam timing. but i would definetley re time the car with a good light

That was exactly what I thought the first time I looked at the graph.. I had a car that was retarded like 5-6 degrees on the intake and it did the same thing..

Compression was 200-200-200-200

Plugs are gapped accordingly, no blow by, no smoke, no burning oil. car idles fine, timing belt and cam timing is dead on the money, reset it twice just to be sure.

car drives fine until vtec then falls on its face. the customer , as i said, bought this head brand new dissasmbled from honda. im thinking some of the rocker pins are missing in the head, im gonna pull the cams out tomrrow

 

take off the valve cover and look at the cams. Make sure the vtec lobes arent ground down or screwed up...

look at the middle rocker arms and make sure each one has the pin installed inside of it.

you may have to take off the cam caps and see if the oil restrictors are there

 

Oh yeah, STOCK CAM GEARS, non adjustable

 

also make sure your wideband isnt fubar

 

we dynoed a 622whp car the day after, wideband is ok

 

have u tried to shut off vtec and make a full pass without it?

bad coil maybe?

 

Had the same problem with an engine in my friends car. Timing belt was a tooth off.

 

still cant find the problem. All the rockers have their pins, timing belt is still dead on. motor runs and drives fine, just falls on its face in vtec

 

can you put an oil pressure gauge on the motor.....ive seen them go into vtec and as they rev fall back out due to oil pressure....it mechanically will not be in vtec and it will be runnign the vtec map in the ecu and run like ****

Just like my damn K20.

 

Ok, your suppose to route the air that the compressor blows out to the throttle body.

 

ok, here what i did:

Plugged all the holes in the head, ran 100psi of air pressure through the allen key hole in the front of the solenoid.

The rockers lock together, but very loosely, the pins basically slide together, but they dont LOCK

interesting.....
