Not enough oil pressure from hydraulic lifter gallery(being low pressure, as opposed to getting feed direct from main oil gallery).

I think the internal vct mod is a bit of a hit and miss some say it works others say it doesn't.

All I can say is that it didn't work for me, and its a head off job to drill and tap for a vct feed line.

Take a risk and find out if it works for you :P

So you ended up wanting to go the 35R? What made you change your mind? Just curious...

Ive currently sold my GTX and just purchased a 35R to throw on there.

currently she only revs to 6500 rpm as anything over that it just stops making power, though still enough to run a 12.1 on 18 inch ling longs.

With the 35R on there I can rev it just that little bit harder and gain that extra 1000 rpm. +fix the vct issue and I am back to where I started in terms of response.

Its win win, fix vct and get similar response to the gtx without vct + have that extra 1000rpm head room to get down the 1/4 quicker.

      What should I do next to hold the head on

      By Gareth87 · Posted

      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
