Hi , im from the Philippines. I would like to ask help from anybody who knows how to lock the vtec rockerarm while the engine is not running. Because I want to know if my valves are heating my pistons when the vtec engages. I have type-r pistons and my head is milled a little. Im going to use type-r cams also. My car is a 1999 honda Si-R.
thanks

you can ground the vtec solenoid... it'll click.... but I don't quite understand what you need to do....

thanks guys ill try to test it tom. if i cn do it with the clay test. thanks

Rob!

yeah clay test would be ideal...

Clay test still only tests the clearance for the non-vtec cam lobes, correct? He would still need to engage the solenoid to check the clearance for the vtec lobes...right?

You can engage the solenoid all you want, but without oil pressure it wont push the valve down any farther. The solenoid only allows oil to pressurize the VTEC circuit, so without enough oil pressure you wont get the valve lift from VTEC.

you could also get a chipped ecu program that does this.

So there is no way to lock the vtec rockers without starting the car. Could you manually push in the locking pins somehow?

Marauder

To lock the VTEC rocker without oil pressure, you can apply air pressure to the head. There is an inspection hole, you must remove the sealing bolt, and then screw in an air line. You need to plug the relief hole with a special air stopper tool. You use 36 psi of air pressure to activate the VTEC rocker.

There we go...that's the info we are seeking! Thanks Marauder!

Step 7 is my favorite!

's to you M

Marauder

I aim to please!

btw....be carefull taking out the sealing plug. I took the one out of the junk head I have, and just breaking the sealing bolt loose I stripped all the threads! Luckily I have another junked head with a good one. I always like having spares around.

i read all these post and not one person asked him how much did they mill the head because this guy is about to do all this work on a b16 just because he put in some itr pistons that are the same as the pr3 pistons he took out and he is only useing itr cams
