Okay so I think I am getting some Crankcase pressure.. Because the other night I was out having a few spirited burns with my mate in his KPro'd DC5 as over all winter we have been having banter as on who's was quicker. But any besides the point we had, had a fair few digs during the night, and at the end of it I went to head home with my brother who was in his EK4 I give it a little bit past his window and all of a sudden smoke came from the engine bay - lots of it. Pulled up and the dipstick had been pushed out of where it should be. And oil was accross my whole bay - yes it took a while to clean haha.
But I know for a fact it isn't because I have to much oil in there also I do know that the dipstick was pushed in properly.
So the last thing it could be is P crankcase pressure. So I took the valve out which goes into the inlet behind the head. As it should rattle. It vaguely rattled but after a good ole clean it rattled a lot more freely. And I did the blow/suck test one way and all was good! Now if this isn't the problem, as I have not driven it yet. Does anyone else have any ideas?
Btw my engine is a built B16 with a stroker Kit. It's mapped at 220 by romain at Eurospec so it's not your standard engine! Any ideas/help would be great!
Thanks!
 
Never mind that,
Who won the race? 220hp ek9 or kpro'd dc5?


I'd give it a good run out now you've cleaned that valve.
Have you done compression test since? So you can cross blow-by off the list of possibilities.
 
Well previously i had beat a stage two VXR which I put a video up of.. And my mates KPrd'd EP3 which is fully stripped with buckets.
And my mates DC5 had too.. So was the big one, Haha.. And to be fair it was a bloody good burn up, if I am truthful I would say 1st 2nd 3rd and 4th I am edging all the way, probably by like 3/4 of a car, but if we done a run all the way through the 5 would have the upper hand. I have video footage of about 2 or 3 of the runs which I will try get up! And you can see the proof in the pudding! Haha

Anyways.. Back to PC pressure.. I do need to take it for a run after cleaning the valve have also cleaned the pipes that all lead to the oil catch tank.
I have not done a compression test no, would you recommend?
 
If its running fine then its probably not worth bothering about tbh.
Was thinking blow-by is building up pressure which in turn forced your dipstick out. But if the car is running as it always has I can't see it being that tbh.

Stage 2 VXR is around 290-300hp depends where it was dyno'd so FairPlay! Take it you run shorter gearing aswell?
I've seen stage 2 VXR and similar power Astra's run 13.5 on quarter mile. At speeds of 105+
So your civic must really motor along

Yeah mate! Check the video bud! It will be on my old posts! Admittedly we went from first gear dig! And mine was gone! Maybe from a 3 rd gear run through would be a closer run.
Thanks for the help anyways man!
 
As for the breathers! Is it easy to add them in?
Only posted as this his never happened before and it gets some stick every time it goes out tbf!
 
Do you think this is from blow by? Have you checked your compression?
 
Iv seen the vid against the Astra and it pulls pretty hard on it!!
Putting breathers in the valve cover isn't hard, I got an engineer to do mine with the fittings. Didn't cost much!

I'd be checking the compressions as well. Also, depending on the setup it maybe a idea to install a breather kit. You shouldn't have problem like this though a that power output unless you have loose ring end gaps or a poor piston ring seal.
 
With a stroked engine you would get a little extra crankcase pressure just due to the pistons moving a further distance than standard, but if you've this setup for a while and it just blowing the dipstick now,something must be up. I'd check compression and do a cylinder leakage test if there is a loss of compression. Or it could just be something silly like the one way vale you were on about (PCV valve), about 30 bucks from Honda for a new one.
 
Umm i think you have a issue here buddy, you have to think logical,

has it done this before

Was it driving any different before/after the problem happened?

I think you have escaped it lucky with just a boy of oil going over your bay could have blown a hole through you block in the worst case. My advise to you is get it proper checked out before you go on a sprited drive as this could be the start of a small problem turning into a full rebuild.
 
Okay! A lot of people saying I need to install more breathers! Well.. The cars been out today after cleaning the PCV valave.. And it has performed as it always has. No change in performance at all! So may have been PCV....

No wasn't driving any different before or after this happened.. Which I found strange no dip in performance.
Yeah that's true mate.. What would you get checked? Compression test? Leak down test? Water pressure test? As I did have some over hearing issues a few months back thought if sorted them and now it happened again today.. But I have never had a change in performance although today couple people did say it was smoking a little and it's never done this before! It's a strange one! As to drive still feels the same
Could be something simple I need to sort.. Any ideas/opinions people all welcome

It won't blow a hole in the block lol. The oil pressure will be a lot higher than what he's experiencing.
 
Check compression first, than make plans or not after you get the results from the test.
