Don't know if you have sorted this out with the induction kit but if not your oil catch can hoses are all wrong. You need to move the blue hoses so that it is catching the blow by vapours from the rocker cover. Just now you are sending clean air via the catch can into the crank case which a simple hose from the rocker cover to intake could do just the same. Just now your catch can is catching clean filtered air! No point in having one if you are using it like this....

Good spot mate!

To be honest I haven't sorted it yet... I did look at it thinking it was never gonna catch oil from the intake or the crank case inlet but I figured it wasn't killing anything so I left it to look at later.

I started looking for diagrams online to see where else to hook it up to but a lot of them mentioned running it off the PCV, and some mentioned welding in new fittings. All sounded a bit complicated and nothing was straightforward. Probably a noob question but where would I catch the blow by vapours from? Is there an existing outlet?

Yes run the catch can between the PCV valve and the inlet manifold. The small pipe on the top right of the valve cover which has a black vacuum pipe between it and the inlet manifold should be removed. Then put one of the blue pipes onto the rocker cover pipe and the other one on to the inlet manifold and connect the catch can in between. Looks like the catch can is securely in place in the photo so it should just be a case of connecting the pipes as described. Make sure you replace the pipe between your intake and valve cover.

filtered Air is drawn into the crankcase from the intake and is blown/drawn through the crankcase and out the PCV into the inlet manifold to be reburned. You want the vapours to be drawn into the catch can while the cleaned up air goes back into the inlet manifold.

Fed my car some v-power today for the first time since she's been in my ownership. I put £40 of total excellium (97 Ron) in when I first bought her and totally forgot that I was meant to stick some octane booster in and the fuel light just came on today. Anyway, I must say it does seem to be running a bit better. It's only day 1 so I'll give it a bit of time for the new fuel & redex to settle in but it still has a few issues...

It takes a while to start occasionally and it stalls at low idle unless I apply a bit more fuel but this is all usually ok once it has warmed up. Now I've noticed a new thing - when it's warmed up the revs sometimes bounce up and down when I stop at junctions etc. Any ideas what might cause this (assuming it isn't just the fuel)?

I've still got an oil change to do and I've got some intake & carb cleaner to spray in too but whilst I'm at it what else should I do?

check your water level

did you do a reset?

Rich · Post by **Rich** » Sun Jun 10, 2012 12:33 am

Not that I know of. Had a flat battery before I started using it though so I disconnected everything & swapped it for the one out of my bb3.

I think the water level thing might be it... I noticed some liquid under the front of the car the other day & assumed it was oil so was gonna put some stop leak in when I do the oil/filter change, but come to think of it - it was quite clear & I'm pretty sure my oil is old & black. So I guess I've got a radiator leak to sort out... great!
