Block pcv after catch can install


Recommended Posts

All, 

Here is my situation. Car is runnig at 1.3 bar with standard gasket.

compression and leak test was done all in green area . turbo is hybrid. not a drop of oil in intake or intercooler

what is causing the smoke is pcv valve . If I block it, car will smoke like hell both mixture of white colour and smoke . We are talking clouds and as if turbo is blown


if I keep it, it smokes and can see blue and at times white colour smoke and I can only assume it is the oil from pcv.

now I am running the camshaft cover to a catch can and the pcv to a can . I think car can't breath or is breathing too much so would a solution be to drill two more hole on the camshaft cover and block pcv?

I verified this by unplugging one side of pcv and oil was fair amount in the bonnet area within few minutes. No oil from the cam shaft covers!!! well there is but a lot smaller.

 

i don't think it is gasket or water coolant as coolant level has not gone done slightest amount in 2000 miles

thought?

You have been saying the same thing since March.

The solutions are in this thread - start half way though -

well it stopped and then it started as of two days ago hence why posting back. to be fair I am starting to use it more often now compared to before maybe why I am noticing now

 

read it and it does seem you need a mechanic and costly solution by drilling oil galleries etc

 

does that means everyone here with 400+ bhp does this ? It is strange how no one lists this problem

when I look on net, pretty much every one says it is valve problem

There are many people with modified engines contributing to the oil control thread so hardly "no-one"

In my experience SAU, while not infallible, is more likely to solve a problem than any other single website.

Quoting you drifter17...

"one question though, i seem to be going from high to low on dip stick every 200 miles or even less so burning around 200 ml "

 

Not the same thing being said.

Wich is it?

Compression figures?

OP has had an oil control problem since at least early March. If you read this thread from the beginning you will see he has compressions of 165 but his leak down test is 10%. The person carrying out the leak down test should have been able to tell him whether it was leaking from the rings or the valves but by the symptoms he reports it could be both.

If you read the oil control thread (say from half way through) you will see that there are ways of managing the problems.

Drifter17, if its not burning oil like it was, why?

What else could it be burning?

If your compression is still the same after driving it around losing oil then not and add blowin allsorts of smoke i would think thats amazing, but after so long seeing wich cylinder(s) are the culprit shouldnt be hard to tell, re test compression, pressure test coolant system and leak test inlet manifold.

My guess is that if your motor seems fine , maybe its a small leak water jacket/intake of the inlet manifold gasket .

Just a guess.

Goodluck!

I am new to this forum but have solved all my problems through this site over the last 5 years owning gtr's.  I had this same issue on my 93. I removed the large custom catch can setup the car came with, reinstalled a new pcv(was blockled) and fitted a Nismo catchcan. motors runs great to this day and like you I thought I had blow by issus and a bad motor. I see very little oil in my turbo piping now. hope this helps. don't give up motor could still be ok.

    • The two diagrams are equivalent. The R32 one is just one sheet out of about 3 showing everything in the whole car all at once. And without knowing the functionality that occurs in the modules, they are both equally opaque.
    • 8v - 2.48ms 9v - 2.15ms 10v - 1.74ms 11v - 1.41ms 12v - 1.15ms 13v - 0.99ms 14v - 0.89ms 15v - 0.82ms 16v - 0.81ms I'm running these values on my RB20 Neo with 570cc Denso R35 stock jets and it's great. Also bought a set for my Legnum VR4, love these injectors!
    • Thanks for your reply,  Those blue/green wires running to the actuator aren't attached to anything, so I'm not sure how the central locking is still working. I will have to take a good look tomorrow, I don't have the car with me. After googling it seems like a pretty common aftermarket actuator which even uses the same green/blue wires the immobiliser required. i'll test everything tomorrow and if it's working i'll melt the solder, strip it, resolder and neaten it all up with some heat shrink. I don't have to understand it if it works hahaha I just don't want a fire/ short circuit. That R32 diagram looks more like a continuity chart? Can you make sense of this form the R34 manual? 10V is probably due to very flat battery, i'll recheck as well tomorrow, I did have to jump start it haha. Thanks again!  
    • So, COM doesn't mean comms. It means common. What common itself means will depend on the type of device. For a two directional actuator (ie, one that can push and pull on the same output rod) then the common will typically just be the earth connection. There will be at least 2 other wires. If you put 12V on one of the other wires, then the actuator will push. On the other 12V wire, it will pull. Can't quite make out what is going on with the wiring of your actuator. It appears to have several wires at the actuator plug, but there only appears to be 2 wires where its loom approaches the door control module, with at least one of the others cut off. I don't know these actuators off by heart. I'd have to look at a wiring diagram for one before knowing what the wires were about, and that's despite me having to replace one in my car not all that long ago. Just not interesting enough to have dedicated memory set aside for trivia like that any more. That actuator is an aftermarket one, not the original one, which probably died and was replaced. That might require some sort of bodge job on wiring to make it work. Although nothing should justify the bodginess of the bodge job done. As to the soldering job on the door module's loom plug. Ahhahhahaha. Yes, very nasty. Again, I cant tell you what any of those wires do. You'd need to study the R34 wiring diagram (if you can find one that shows the door module). I don't think I have any. I'd have to study the R32 diagram to start to understand what mine is doing, and again, even though I've had a problem with mine for the last 25 years (where it locks the passenger door when the driver's window reaches top or bottom of travel) I'm just not interested enough to try to to work it out. So long as it's not burning down, it's fine with me. Here's the R32 GTR diagram, which, confusingly, has rear door lock actuators and window motors on it!! As you can see, unless you understand the functions of the door lock timer and the power window amplifier, you'll never be able to work out how it works just from the diagram. I don't imagine that the R34 one is any better. Hopefully an R34 aware bod can help. FWIW, the two wires that are cut and joined look like they are both power supply - so hopefully it is not fatal to join them. The 10V you measured on the cut off free end of one of them is concerning. You'd expect 12V, and it might be the reason for the bodge job joining them together.
