Was there an issue with oil starvation around the cam?

Potentially - this is just a way to keep a small bath of oil in the head to assist the lube of the cam

These little gizmos are a must in a CIH engine Opel GT.  In the GT the engine is tilted around 5 degrees towards the passenger side (LHD) and then tilted downwards towards the rear of the car, resulting in potential oil starvation to the cam and lifters.

never seen one to that design,usually they are just a tube .or the ones ive seen are .

they were fitted to later 2 litre engines .not sure about the last year or so of 1.6 ones. and never heard of a 1.6 wearing out its cam lobes but seen many an early 2 litre do it.usually on cylinder three for some reason so definately a worthwhile mod.

Got one that style on mine. Seen a few of the German companies doing them like this now.

Pretty sure these fit into a drain hole in the top of the head. To help keep a puddle of oil sat on top.

just wondered if they just pressed or hammered in. My worry would be it coming loose and bouncing around the top. 

Sounds to me like a piece of pipe the right size would do the same job.

Did some years ago a overhaul of a 1.9CIH Manta A head, was original no stemseal head but milled it so stemseals did fit. Pulled that pipe out a 2.0 head  and it looked as a sheet of 

metal that whas wrapped. So it gave some tension in the hole where it belongs, you can find it when you open that cover on the back of the head:

I have been  after  one of these  since I had my engine  fully refurbished  years ago. The guy who did my engine  recommended  them as it helps save excessive wear and premature failure of the  camshaft. 

So  recently  purchased  one off ebay  for my  1900 coupe. 

Fitted  it yesterday. 

Nice easy  job. 

Got engine  up to temperature  and removed  rocker cover..Then carefully  tapped the  oil level raiser into  the oil return  hole  at the back of the  cylinder  head. 

Then refitted  the rocker cover. 

Job done.😁👍

 

Just make sure  you have your tools handy  to do the job and to gain access  as quickly as possible. 

As you need  the head as hot as possible  so everything  has fully  expanded. Easier  fitment of oil level  raiser...

Just be careful  not to burn yourself 🤞🤪.

 

Good luck.

Just thought I’d check mine now I know where it goes, only to find it’s already there. We’re they fitted to later models from standard ?

Can it be seen through we cam removal hole in back of head, without removing the rocker cover?

Seems the easiest route?

Old school guy once told me CIH GM engines died at high revs due to oil starvation, when driven at  9/10ths. Heads would warp! Thats oil starvation cured!

Any upgrade for coolant flow?

They do the job nicely. 

Makes a big difference on starting the engine. Oil already  at the top  end...

Alot quieter and I thought mine was  quiet to start off with anyway 👍.

Well worth the money and time 😁.

Can this mod also be done on the 2.4 CIH engine ?

 

It will fit all cam in Head engines, fitting can be done with engine in the car, rocker cover off. It's quite simple.

 

Many engines already have a version fitted, I used to fit a length of copper pipe to any I encountered that did not have it .

These always came as standard fitment for all Irmscher conversions, even as far back at the late seventies. When I bought a new Enem cam for the i200 in 1990, the Oil bath raiser tube was part of the kit.  I have just made a small order for half a dozen of them, so we can put a few on sale via the club shop.
