Excessive Blow By


Recommended Posts

hey there,

i got r33 gts-t 372hp atw on standard internals, and lately there is a lot of blow by oil coming through air filter, i installed catch can but its a dodgy one where oil and air are not separated so oil just gets sucked back into air filter and leaks through air filter...its like prolly at least half a litre of blow by, but when reving the car at neutral there is not any traces of oil so prolly happens on high boost (16psi through high mounted t-57 ITS turbo)...is the engine on the way out? car still seems to go same as before, is it time for rebuilt?

regards

That happened in the first motor we had before we found out the ringland was cracked on the piston. Infact, we were making roughly the same power too, and the car would still pull and idle find. It didn't even seem as though there was an issue at all. I would go to a leakdown or compression test immediately.

    • I am currently going this route. I am curious how much horse power you put behind the cut bell housing? Collins was telling me I am going to crack it and bluh bluh bluh. Because I didn’t buy the custom fly wheel from him. I am looking for somewhere around like 500 hp
    • Forgot to mention that these are the before pics when I first got it!
    • Thanks @PranK for the updated member status, much appreciated! 👍🏼 Now, about those pics… Unfortunately I could only find ones that I took in the dark. I was soon to discover that underneath it wasn’t in the best shape, but it was mine and that’s all I cared about at the time 😆
    • Oh, and only having done this task yesterday, I've now driven the car ~60km since, and while it is hard to avoid placebo effect and confirmation bias, I reckon that some annoyances I had with the way the car has been behaving have improved. Which....kinda makes sense, I guess. If the bushes were really stiff and resisting rotation, they would have been contributing to the effective wheel rate. And if it was more so on one side (which it was, because one side was worse than the other) then.... you might imagine that the additional rate would be asymmetric, and potentially even different between compression and rebound. And so... the car has been twitchy at higher speeds - like freeway on ramps. It really shouldn't be. The wheel alignment is good and there are no (other) known problems elsewhere in the suspension. But at 90-100 on a long sweeping ramp, tiny steering wheel motions would make it feel like it wanted to rear steer. Quite nervous. At lower speeds it would heave about in a manner that it didn't use to. Didn't want to put power down, etc etc. Now...seems to behave better. Am going to have to concentrate on the various corners where it has exhibited weirdness, on the rare occasions when I can get a decent run at them without Methanial getting in the way in his D-Max/Ranger/LDV Van/etc.
