R33 Gts-T Knocking Noise

[mbwilding]

Hey. I just got my r33 gts-t back on the road. Redid the timing and she was running sweet. Had the timing fairly well advanced, and the car had lag issues before but the advanced timing via the cas fixed that. Went and did donuts and holding just below 7k and I have a feeling the radiator had not much liquid in it and it seemed to be overheating. After I finished spinning and pulled out from the burnout the car stalled. After I got the car started it seemed to idle alright, but there was a strange knocking noise and it seemed to be coming from the rear cylinder. So I got the car toed and haven't bothered to run it because I am afraid I might hurt the car.

It had been blowing white smoke too.

Does anyone know what could be causing it and or how to fix it?

Much thanks in advanced.

Matt.

do they have tappets or hydrolic lifters? sometimes they fail under strain..

maybe stop doing burnouts?

[rickr333]

In my experience with other older types of cars (not imports or nissans but hey an engines an engine right??) white smoke usually means water getting int o a cylinder from a f**ked gasket or cracked head hopefully just head gasket try letting it idle with radiator full and look for bubbles, if u get them then gasket. Theres another way where u use a compressor thru the spark plug holes and also watch radiator but Im not 100% on that one

Was there water in it in the end??

It only seems to tap on idle, when the revs picked up it goes away I think. Could injectors cause this? higher fuel pressure at higher rpm masking the potential problem with the injectors?

@AaronNM35

Pretty sure it's stock so it would be tappets. thanks for the feedback

@rickr333

There was coolant in it, I had to dump it when we were looking at the engine. Thanks

You did burnouts at just below 7k rpm and you're wondering what's causing your knocking problem? Give me a couple of days, I have to come up with some theories.

I also am afraid.

Try doing burnouts in a higher gear. So u dont stress the motor so much

My mates found the problem. the rear piston con rod has detached from the crankshaft, or is loose

We are going to rebuild, thanks

.. why oh why did they get rid of the rep system - perfect opportunity for people to put it to use ..

Minor issue... Just stick to 6000rpm and it should be fine

there's ya problem

that's a surprise

I thought it would have been due to faulty headlight wiring

+1 for you

but im sure you checked the oil level first....

[Birds]

Oh a loose conrod, that's not right...your engine timing must have been slightly out...can't think of any other cause. Tell your engine rebuilder to use a left handed torque wrench when he's torquing up the end caps...RB engines respond to them more positively than conventional torque wrenches...a lot of rebuilders don't know this.

[tm_r33]

Also make sure you do some more burnouts to run new engine in. kicking the clutch regularly and changing road surface mid burnout should do it

my cosin werks for nissen an he rekuns dat yur enjen is brocken bro

my mate rekuns u shuld chuk in a holden RB30 enjen wif a doze pip u cn rip mad az skidz bro.
