As some of you may be aware i slipped and broke my GT-R yesterday.

I need helping with ideas of what has happened. the Symptoms are:

High pitch noise and white smoke from under the bonnet when trying to start.

It did start 1 time but i had a huge amount of white smoke out of the exhaust.

When we took our foot of the gas the car immediately cut out again.

Im thinking ive cracked a hose somewhere and the started motor may have pooped itself.

Thoughts?

IF anyone is keen there is a 6 pack for the person who knows what the problem is. as i'm pretty stumped at the moment.

I will be doing compression tests and all the random stuff on Saturday but i would just like some ideas on what it might be so i know where to go.

Thanks guys

yeah the smoke is white, very white. but i have not seen the smoke since yesterday when it first broke. the car won't even attempt to start now. its got that high pitch noise and a bit of smoke under the bonnet when it tries to start. hence im thinking starter motor. but im unsure

I think started motor but im not sure. im still new to the skyline engines. but yeah it sounds rooted. but im unsure as to what else is wrong. because the whole car just died on me on the way home. i thought i might have run out of petrol but after all this it can't be petrol. so im lost. hopefully me and a few mates can figure out whats wrong tomorrow. p.s Anyone Thats free today that lives like condor area free that might have an idea?

thanks guys.

what exactly happened when it broke? Ie were you driving and it all of a sudden let go? with a big cloud of white smoke coming out the back? Was the turbo boosting at all after it happened? or did you shutdown the car straight away.

I was at idle going around a corner and the whole car just gave up, rolled to a stop. i had boosted about 3 minutes before hand. no smoke when it did die. I think what has happened is i was low on fuel and there was some gunk in the bottom of the tank and ive clogged my fuel filter somehow. and my started motor just chose this time to die as well.

Check the normals such as coolant color and see if it's got oil in it. Vise versa with the oil check if it's got coolant.

Maybe post up in the forced induction or general maintenance thread they will have a good idea as well.

Check for fuel so maybe pull the line off the regulator and prime it to see if fuel comes out.

Also pull the spark plugs out and make sure it's getting spark.

Im getting no response at all anymore, when it was turning over i got white smoke out the back off the car as well as a bit under the bonnet. tomorrow im pulling the fuel filter out as well as the starter motor. from what i can see i may have lost a tiny bit of oil, coolant is fine however. I was thinking head gasket to begin with but now im not sure. as when the car died i was low on fuel its very suspicious...

when i say no response my car the started motor sequels in pain however it does try to turn over, i know it isnt spark plugs/coils so im thinking its fuel related or a head gasket. i think the starter motor just decided to brake at this time and it isnt related (i hope).

What did the smoke under the bonnet smell like?

Have you ever smelled fuel thats not burning but its so hot it turns to white smoke? a very odd smell.

Do you know what fried wires smell like? (starter motor)

The other white smoke is coolant burning, after all the water has boiled away. smells like a chemical factory. like its gunna choke you.

Your nose is a chemical sensor that is very easy to use.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
