Hi All,

So long story short, I went to get a tune lastnight and my RB25 made a lousy 230HP on 13psi. Tuner said that my VVT solenoid is not engaging & my Blow through MAF (Stock MAF) was maxing out at 5v @ 6500RPM.

QUESTION: Is there any easy way to test the solenoid? I believe it's just stuck or not engaging properly as i have power to the solenoid but nothing happens when it's applied.

The solenoid will be negatively switched. Use a noid light or a LED test light to see if the ECU is switching the earth.

Is there a way to test with the VVL solenoid out of the car?

I've removed it to try and apply power and ground to it and see if it clicks or moves. I get nothing, no clicks no moving parts nada.

to test if its the ecu causing the issue or the solenoid itself, get a small light, a brake light or something and connect it to a plug, with 2 wires. make sure the light works of course, then disconnect the solenoid and connect the light in its place, then run the wire over the engine and over the winscreen and onto the dash board where you can see it.

take the car for a drive and simply see if the light turns on! if it does not switch on then you know you got issues.

i barely ever see issues with the solenoid itself, its always an external factor, but in your case if you have connected power and ground to it, you should hear it and feel it click on and off.

      What should I do next to hold the head on

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
