Ben C34 Posted February 5, 2014 Share Posted February 5, 2014 There's an oring behind that bolt. theres oil in there fot the vct to work. Check it out and replace it. I cant see hiw overfilling it would damge it, how much overfill are we talking?

walky01 Posted February 5, 2014 Author Share Posted February 5, 2014 when you're revving at 7500 i guess it has to come out somewhere.... Link to comment https://www.sau.com.au/forums/topic/438720-rb2530-de-cam-leak-need-help/#findComment-7190326 Share on other sites More sharing options...
Ben C34 Posted February 5, 2014 Share Posted February 5, 2014 So its a pretty serious build? Omly reason I ask is I can see a bolt blocking off a small coolant line in the photo I doubt the leak has anything to with revs or overfill. Its just a leak.

r31 25t Posted February 5, 2014 Share Posted February 5, 2014 I thought there was a cover over that bolt through the centre of the vct gear, has an oring too. Bolts on using the four small bolt holes you can see.

walky01 Posted February 5, 2014 Author Share Posted February 5, 2014 I never knew that. It's never leaked before considering I had the engine rebuilt 2000km ago you'd think that would get changed.

Ben C34 Posted February 5, 2014 Share Posted February 5, 2014 True, I was thinking if the neo vct which has a plug that seals it off, pre neo uses the plate.

89CAL Posted February 5, 2014 Share Posted February 5, 2014 no seal between the bolt and the cam. Should have the bolt with a washer behind it. Then a spring and plate with o-ring on top of the bolt. Ive had that one off quite a few times when building my engine Id expect a little bit of leakage past the bolt but nothing major. How come the cover is off?

walky01 Posted February 6, 2014 Author Share Posted February 6, 2014 It's not a cam seal though it's an oring that sits behind the Bolt holding the can gear on, oring on that or am I wr Link to comment https://www.sau.com.au/forums/topic/438720-rb2530-de-cam-leak-need-help/#findComment-7191469 Share on other sites More sharing options...
Ben C34 Posted February 6, 2014 Share Posted February 6, 2014 The neo engine has a different vct setup that uses an oring behind a bolt to seal, which is what I was thinking of. Pre neo is different as 89cal pointed out 2and the image I posted shows that. You are missing the cover and the seal.

Dose Pipe Sutututu Posted February 6, 2014 Share Posted February 6, 2014 wait you're missing the cover, spring, seal and those 4x 6/8mm?mm bolts that's why it looks funny, also if that's the case how does your VCT function properly? I'm sure that spring in there to shift the cam sprocket Link to comment https://www.sau.com.au/forums/topic/438720-rb2530-de-cam-leak-need-help/#findComment-7191593 Share on other sites More sharing options...
walky01 Posted February 7, 2014 Author Share Posted February 7, 2014 Now thats what im thinking, its gone through a few guys on the forum as far as i know it never ran it, it only started leaking now after 2 years? im so confused lol Link to comment https://www.sau.com.au/forums/topic/438720-rb2530-de-cam-leak-need-help/#findComment-7192012 Share on other sites More sharing options...
Dose Pipe Sutututu Posted February 7, 2014 Share Posted February 7, 2014 yeah needs a washer, spring, 0-ring, plate and 4x plates I wouldn't be surprised if your VCT is not working Link to comment https://www.sau.com.au/forums/topic/438720-rb2530-de-cam-leak-need-help/#findComment-7192018 Share on other sites More sharing options...
