Hi all,My mothers car broke down, so I did the nice thing and leant her my r33 gtst whilst hers is getting fixed. Anyways, heres the story,Driving along the M1 she says it lost power and gave her no warning. Pulled over and stopped the car and then inspected to see radiator hose broken and no water, and a cooked enginer. Oil was black and burnt to the buggery.So i was then told that some nice fellow helped and got the radiator hose fixed and and put it all back together and topped up the oil and water, but now it wont start.The oil pressure gauge does not move when cranking. Maybe this has something to do with it.I will do a comp test tomorrow when I get home but can anyone else suggest something else to look for? I know im probably looking at rings but hey, heres to hoping.Might do an RB30 bottom end now.

It turns over but has a slight bad note(Although i listened to it over the phone). seems to go dum dum duuuum dum dum duuuum dum dum duuumThere was no oil in the radiator, and no water in the oil.No oil or water leaks that can be seen (After fixing radiator hose of course).Cheers guys.

You have probably warped the head. Most good repairers will not touch the head now (ie try and straighten it).

Time for a new motor.

Alright I confirmed my fears, theres no comp whatsoever.

Now, how do i pin point whether it is rings or the head? Would like to think some of its salvagable.

I would have thought if the head was warped, you would still get comp in a few cylinders? (Along with water in oil and vice versa) ??

Your block and bottom end should be ok but the rings and the head will be shot.

So wouldnt there be oil on the spark plugs if the rings were shot? or wouldnt the pistons be slapping around? Ahh well ill replace the whole lot I suppose seeing as it looks like it cant be rebuilt.

I love it how this shit happens straight after you buy a boat lol

sad isnt it :laugh: I wouldnt mind if it happened revving at 7000rpm punishing it. But to come to its demise with a harmless lady behind the wheel was dissapointing.

I was experimenting before, and I poured oil into the cyl and the comp readings rose. I heard this is how you tell if its the rings. They went from 30~40 to 120~130. Does this conclude that its just the bottom end?

Say I took the head off and with a metal ruler there was nothing wrong with it? Does this mean that its all good?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
