Gday guys, I have a problem here, possibly more than what i first thought. This is the problem. In the mornings, the car will start fine, and run fine. But, after a while, once its warmed up etc.. it will start dropping cylinders. as if the fuel is not being burnt? i have checked the plugs, they are fine. I have checked the coilpacks, and the resistance seemed to come in at the correct ohms. But, it just seems to not want to work.. So thats why i ask what would be the symptoms of a cracked block? maybe its leaking water into the block causing non explosing? any ideas people?

Thanks for your help.

Coil packs for sure.

Unplug each one whilst its running warm. When you find the pack that makes no difference to the way its running, you've found the dud.

If it were head/head gasket there would be steam out of the exhaust and oil in coolant/coolant in oil

I bet its the coil packs, one or more is stuffed its a common R32 problem.

Ok, i will take a look at that, see what happens... so im assuming you mean, pull the plug of, and on again. Im pretty sure thats what your refering to. i will take a look at that. If it was pumping steam out the back end, would it be a white colour?

Yeah that's what I mean, unplug and plug one at a time. :(

It will be white yes. You can also get an 02 tester. Mechanics have them. You stick them in the radiator inlet when you remove the cap and pump it a few times. If you have a stuffed head, the liquid inside turns to green from blue.

Takes about 10 seconds to check.

      Nope, still smaller rear, put on the 4inch exhaust and picked up power everywhere, ended up just shy of 800rwhp.   Didn't seem to be hitting any walls either, so perhaps could have pushed for more but all maybes and the fish that got away etc etc.

      This could be sold and shipped to the US for many gold pieces. RMS has no say in that. Ask various Western Sydney inhabitants how it works.

      Ha ha ha, mine loves to spend, all on the dogs (they're our kids, and her spending would likely rival that of some people raising children!) the only benefit is, her spending is tax deductible as she runs a business in the dog industry 😛 The above all means she can spend race car budget quicker than I can. 😛 That and a lot of the things I want are very expensive, and I can be a bit "you want how much for that?!" And at other times overly impulsive. Or I start the w days of research, get to day 1.5 and get really annoyed that no one will advertise actual specifics and it's just marketting BS and I go "well, now I don't want anything to do with that now!" Also I hate paying lots of money for something I can make from $50 in materials. Then I get the shits halfway through making things and wonder why others who just buy parts have more fun... 😛

      Their 240Z with the RB26 would be a real nice thing to have in a garage to come out for an occasional weekend cruise It's such a cool thing in so many ways Sadly, we have a blue 240Z shell that I walk past every day, just sitting outside a shed at work, it has been slowly disintegrating and falling apart into the ground for the last few years, the owner cannot be found, and I am unable to "claim it" I've been told by work and the RMS, the rust in the body is excessive though, and it has had most of the salvageable stuff, like panels, trim and switch gear stripped off it over the last year or two, work keeps threatening to put it in one of our metal scrap bins, I wish they did though, as it makes Mark sad walking past it
