H22 w/2 problems
 

H22 in a 92 civic CX
P28 Chipped (base tune) & stock P13
Sk2 IM (no egr)

problem 1. vtec disengauges after 2-3k rpms
VTEC will engage, will last for about 3k RPM's then Cuts out and a cell comes on. Code 21.
Manually checked solenoid , and it clicks/engages.
Hard wired it from the solenoid to the ecu. (A4 pinout). Still will only engage for about 3k RPM's.

problem 2. Leak coming from top right corner of head.
Thought it was just a bad seal on the HG, so I replaced it with a new one. Still leaking , same spot.
The whole build has about 90miles on it. Gotta work out the bugs, so we can boost.
If it matters The motor:
H22 Sleeved by Benson
9:1 CP pistons
Eagle rods
balanced crank = Benson
New everything H2O pump,oil,belts,bolts,bearings everything
Morosso Oil pan & pick up (replaced after 90miles with stock set pan/pu)
Head PnP by Portflow
Supertech valve train
new seals
Skunk2 Pro-seiries IM
BDL 70mm TB
Hasport mounts
DSS axels
Kazaa LSD
CC twindisk

Lol at kazaa lsd. Are you losing oil pressure?

Re: H22 w/2 problems
 

what was I spelling?kazaa? KAAZ LSD.

as for the oil pressure, I'm not shure. I have no press guage hooked up. I thought about that, but wouldn't my stock oil light come on, or start to come on if oil press wasn't there?

top right corner in red...

Attachment 10357

that is where my oil spell is happening. This is the 1st H22 I've ever worked on, so I'm starting to 2nd guess myself on little things.

Such as, should the dowl pins be on the front of the block? I noticed that these are placed on the rear. Witch got me to start thinking, maybe thats why it leaks in the back?

Re: H22 w/2 problems
 

No the oem light is the 'your ---- is now fucked up' light not going to tell you there is less than 70psi or whatever it takes to engage vtec.

Re: H22 w/2 problems
 

good point. I'll head down to the parts store tomarrow and pick up a press guage. See what its at.

Re: H22 w/2 problems
 

your gonna need a T off of the oil pressure sender and a line to hook iot to the gauge, i have a pressure gauge that would work as a oild or fuel pressure gauge. IM me and let me know if your interested before you head into town

Re: H22 w/2 problems
 

get a tuner toys fitting or the stealthmode

It makes this ---- way easier than stripping the threads.

Re: H22 w/2 problems
 

I'll have to look into those. I'm on my way now to shucks to get the guage.

Re: H22 w/2 problems
 

I have the same issue, though I replaced my cam seals and it went away for a while but now it's back and my cam seals are not leaking. Just fill the bitch with RTV and see what happens.

Re: H22 w/2 problems
 

And your running leaner on the #4 cylinder or your gap is bigger on the plug

Re: H22 w/2 problems
 

that gap might be bigger on the plug. I'll check it once I work on the car again.,

Picked up a oil press guage, and order the fitting from stelthmode. Just waiting on it to see if I can see a drop in pressure.

I really dont think its my cam seal leaking. I don't see any oil on the back side of the head, leaking down. Just on that 1 spot.

Re: H22 w/2 problems
 

More than likely its a cam seal. I did a H22 build and it leaked there. It was even a brand new cam seal, (aftermarket) I swapped on a used B16 cam seal and the leak was gone. Check the cams as well make sure they dont have a huge groove on them, this is where the seal rides. I recommend using emory cloth/scotch brite to make it smooth.

Re: H22 w/2 problems
 

Aftermarket fuel rail or stock one?

Re: H22 w/2 problems
 

He's using a BDL rail.

Re: H22 w/2 problems
 

hopefully that will take care of the oil leak.

I think the fitting came in from Stelthmode today. (package @ moms house).

If so I'll switch out the cam seal tonight and plug in the oil guage.

Re: H22 w/2 problems
 

Thats the explaination for the #4 running lean, BDL's inlet fuel fitting overlaps the injector boss port so the fuel has to backwash to get to the injector. Try removing the inner steel collar and filing down the port fitting.

Re: H22 w/2 problems
 

Thats not it son.

Re: H22 w/2 problems
 

the T came in saturday. So today after work I'll hook up the oil guage and go for a drive. Updates later on tonight.

I did mention that this motor will be boosted?

Re: H22 w/2 problems
 

BINGO* You really do know your stuff Jeff. It is the cam seal. Got my nose in there and really watched it. There was a leak dripping down the head onto the block

on to the next problem. VTEC disenguagement.

Oil pressure guage hooked up results.

Idel: 30psi
driving: 80psi
floor it lightly: 94psi
just befor vtec hits: drops 2psi (92psi)
VTEC : 100psi (maxed out guage)
VTEC shuts off dropped amost 2psi. (this is in 3rd gear) just about 99psi

Now what?

Re: H22 w/2 problems
 

If oil pressure were the problem you'd get a code 22 for the pressure switch, not a code for the solenoid.

If the VTEC assembly was hogged out/worn so there wasn't enough actual pressure to maintain VTEC, but the pressure at the switch was still >50-55 psi so the ECU thinks there's good pressure, then you would pop in and out of VTEC with no codes.

You really need to triple check your wiring, and test with another solenoid, test with another ECU. Start with the VTEC solenoid, and check the screen for bearing debris. Any VTEC performance engine you should pull the VTEC solenoid every oil change (or anytime there's a wierd problem) and check for debris, it will save your a$$. Buying rods/blocks/cranks gets expensive.

I've seen a few odd P06-->VTEC conversions where VTEC works fine but throws a code 21 the instant you let off the gas pedal, I typically disable the CEL. Doesn't sound like an issue here, I mention it only for trivia since I've covered just about every other VTEC problem possible.

Re: H22 w/2 problems
 

Did you guys end up installing that o-ring right under the center cam holder?

Re: H22 w/2 problems
 

We have tried the P28, and a stock P13. Both ecu's result in the same thing.

Also tried another solenoid and another new screen. Still nothing.

Added a couple more gorunds to the motor/vc/head tonight to see if that might be a factor. NOPE.

and Yes, we installed the proper o-rings in the head. (2 of them).
