PR3-3 head non Vtec, WTF????

[39erman]

WE had been chasing a problem on the dyno where the Vtec wouldn't engage. Could not find anything wrong. Was starting to think that maybe I had the wrong head gasket or something.
So It's been parked for the last month or so and decided to pull the head off. Cometic gasket is correct, head is stamped PR3-3 but there is NO Vtec oil hole in the head next to the head dowl. :eek:

So are all PR3 heads Vtec???

What's the date stamp on this head?

What's the date stamp on this head?

29961

I'm guessing that it's an '09 year?

[Richard B]

isn't the year normally the circle on the left?

Post a picture of the actual head itself. if it has a vtec solenoid and secondary cam lobes/rocker arms it's a vtec head. there are plenty of things that can stop vtec from engaging, but the most common seems to be faulty solenoids. I hope you checked that out first before pulling the head?

Per the pix, I believe its defiantly a PR3-3 Vtec head without the oil feed hole???

Is this right?

need a picture from the top at least.. i can't tell if it's a vtec head from the one you attached.

If it is, it does appear that it's missing a hole there. what kind of engine block do you have? is this a B20vtec or LSvtec type conversion or something?

[39erman]

Block is a B18C.
