What could this be? attached video

[amnash]

did some work on the skyline (oil cooler filter relocation, rad hoses and power steering lines) and wanted to start the engine and bleed coolant and let it idle for a while to get oil through the cooler etc. so engine was running for a good 10 mins water was up to temp and was trying to get the rear speakers to work while it ran(another story) and all of a sudden the engine stalls and there's a slight bang... try to start it again and it just wont start.. the video below is me trying to start with WOT and while cranking there is a knocking coming from turbo side.

first i thought the power steering pump was siezed becasue the previous day i started it up and the pump sucked the reservoir dry filling the new line, soon as i noticed i shut down got some fluid topped it up today before starting and was fine for the first 10 mins. removed PS belt and issue remained.

the oil i put in was 5w40 amsoil, i know its a bit thick. but the temp was about 5 degrees was thinking maybe the oil was too thick to reach some parts of engine causing seizing somewhere?? maybe to thick for turbo lines?? .. i hope not. during the first 10 minutes of running the oil didnt was up that much either(the gauge didn't even move yet, gauge starts at 140F)

could installing the oil cooler filter reloc. lines backwards F things up? (im pretty sure they're installed correctly, used greddy's diagram)

Man... that doesn't sound too hot...

5w40 should be ok for that temperature (it's 5W cold weight after all) but I'm wondering if you didn't get starvation while your cooler lines and core was getting filled (also does it have a thermostat, maybe there was a huge pressure drop when it opened?)

[amnash]

i check oil level constantly and it never actually changed... this car is gonna give me a heart attack anytime now.

i installed the cooler lines in accordance with this picture:


But this picture on FRsport is making me think i installed the to and from engine lines backwards..

[amnash]

could oil starvation to the engine actually seize it enough so it wouldnt start?? and again.. the dip stick is showing lots of oil (almost 5L in there)

edit: went back and got one last video thats better quality.

Make sure you don't have too much oil and hydro lock your engine. I don't thing you seized your engine, a major oil seizure usually stops the engine completely . Given that you changed the ps hoses and coolant hoses there's a possibility that you broke a vacuum line or something. Look around where you worked and double check the oil relocation lines

[amnash]

can someone whos installed one of these cooler kits confirm if ive installed the oil lines going from the engine to the filter block correctly or not? again, installed them the same way as the Top image. and the second video shows the lines on my car.

[amnash]

would the engine run for 10 minutes though and then suddonly hydrolock?? the oil was to the FULL line on dip stick on start up, wanted to compensate for the drop when core filled. i will take the spark plugs out and have a look though just in case.

Will the engine turn over? I've seen bad hydrolocks caused by faulty injectors. They basically fill the cylinder with fuel. You cannot compress a liquid so it stops the engine dead.
Sorry if I'm off base, can't see your vids on iPhone.

Edit: Ok, saw the vids. That looks like an rb25 right? If so, the cam phaser in the intake side may be to blame. If oil pressure is lost or too low it will adversely affect the phaser's position thus giving you incorrect valve timing. On the flipside, if dirt or debris have gotten into the system it can also cause the phaser to fail by plugging it's oil passages. Incorrect oil viscosity will also effect operation as well.

So as of now the car will not start and run on it's own?

It not oil starvation. But your cooler line is definitly installed backward so i think oil passage was block itself because oil fiter is made to work one direction only
Did you have oil pressure reading ????

just went and removed the spark plugs. the plugs aren't fouled and the top of the pistons are nice and dry. so its not hydrolocked.

great... the diagram i used clearly shows the exact opposite of what youre manual shows... im so F**king pissed.. i dont understand why there would be two different diagrams..

i will switch the lines around and see what happens.. but if the filter acted as a check valve preventing oil getting back into the enging its probably f*cked the bearings.. fml

whom ever made that false diagram needs a bullet to the side of there head.

[nick-nismo]

ya you have it correct. i remember hearing how some people don't like the greddy coolers because if you smash the cooler, the debris (if any) doesnt pass though the filter before it enters back into the engine.

[amnash]

the way i have it installed is correct? or the picture showing the two diagrams is correct?

[caliber676]

If you really felt so inclined you could take the system out and put the oil filter back on, see if the car starts. Otherwise I would get concrete evidence that your relocation and cooler is set up properly before starting again

[amnash]

im pretty confident it will start, im just hoping that knocking sorts itself out. if voodoo is correct about the cam phaser thing(that i didnt know about) it makes perfect sense if the timing was thrown out that it was having trouble starting all of a sudden.. the car was running fine for 10 minutes then a slight bang then trouble starting. I'll switch those two lines tomorrow , that cam phaser should get its oil pressure correcting the timing and start it up... and prey to the car gods that knock goes away (I'm not very confident it will )
