4AGE popping dipstick

[Nikkojoe]

Did you happen to read my post above? It doesn't vent into the intake directly so to speak, it vents into the throttle body. The fitting on the intake manifold doesn't go straight into the air chamber, but goes in a little channel on the side of the manifold to the port on the throttle body.

-Cut and shut will block off the breather
-Using rwd bigport intake manifold WITH fwd throttle body will block off breather (fwd have the port on opposite side - you could drill it out though).

Oh, now it makes sense. I thought it just went straight into the main chamber.

My manifold is a RWD one. But someone has been messing around with the throttle body so it could be blocked... Will have to check that out.

[Nikkojoe]

I had a look at your build thread, your t/b is a fwd one (can tell by the direction of the vac ports on top - both point forward on fwd where as rwd will have on forward and one to the side).

Also you could put a fitting onto the intake pipe between the filter and t/b and run the breather into that.

Its really easy just to mod the FWD to work the same as the RWD. Works out a bit neater than trying to route it in somewhere else too.

dig from the stoneage, Just got my rebuilt smallport running 'again' and went for a couple laps of the local streets running the car hard.... got home to find my dip stick popped and oil everywhere..... Now I have had this engine running quite a bit without actually putting it under any load as I was trouble shooting other problems... I did notice that it became quite smokey out the exhaust and the top of the pistons were oily when I took the plugs out (plugs were reasonably clean though)

Could this be an issue where the rings didn't bed in and now its got blowby issues? do I still have a chance of been able to run it in so it fixes itself so to speak... ?

Should I just vent the cam cover breather to atmo and continue driving?

What did u do with the breather? They need to either plumb back into the inlet or the atmosphere.

Does the 16v have a pcv valve in it?

[Sam-Q]

how many km has it done? what's your break in procedure?

[NIZLAH]

just over 20 km Sam, first proper drive was today, (the first time I got it running the rear main seal popped out (could be related) I just went for another drive with the cam cover breather venting to atmo and the manifold port blocked off (was hooked up like factory), although I didn't drive it as hard the dipstick seemed to stay in its home this time round... drive was cut short though due to my epoxy bypass pipe repair failing..

Break in is just drive it and keep it under load and what not, Ive reached the point where my care factor has gone out the window so I'm just driving it in typical fashion...

Smoke seems to have gone from exhaust, not sure about when driving but cant see any major plumes behind me..

[Sam-Q]

being so new I would say give it some time, don't rev it over 5000 yet and use 3/4 throttle as much as possible. It should be good yet.

[Matt]

Its pretty normal to have blue smoke for the first few kms...

I'd stick a compression tester on it.
