E28 Alpina Build - by Pedi

7 minute(s) of a 417 minute read

Back to business, I have been on vacation etc lately...






Time to install the filter housing back to the block.







Maybe it was the plug? - see item #3:







Pics do tell it is in place. Damn....







Measuring how to isolate the head from block.






Random shots of oil channels..






Oil channel to pressure switch.:







Custom made item to stop oil come into head... This will make oil only into block area.






This is how it looks like






My thought::






Mounted...










Cranking the engine makes an oilpressure in block 0.7 bar, 0.2 bar towards head. Way too little... Filmed a sequence of engine cranking, sorry bad quality.







Engine started: 1.2 bar @ warm engine 1800 RPM in filterhousing, 0.2 bars measured @ head. Strange?? PS! Pic shows 0.5 bar to head, pressure lowered as engine got operating temp.






My thoughts now::


I cannot understand anything else than the thought of oilpressure dropping in block now.

SÃ¥ what to do?

Change block?

I guess that that would be the best thing to do.


Anyone else with similar experiences?

Oil pressure is supposed to be (BMW spec):

Cold engine idle: aproxx 5 bar
Warm engine idle: 0.5 - 2 bar
Warm engine 4000 RPM: 4 - 5 bar

Cranking engine: 1 - 1.5 bar

The Alpina-block is based on a M106, so yes, the oil nozzles are present.

They should all be there... Hopefully... I only have one picture of them (not on my laptop here @ work), and those who are visible are present...

EDIT: I found it on page 2 in this thread... :

Just wanted to share some pictures again

I have decided to do something with my shadowline, as I do not feel comfy with the Sepang Bronze color and the original Shadow black. So....





Airfilterhousing needed some paint also :





Rear lights too:





Windows front/rear:









































Aaaand:














Even one of my cats enjoys the Comfort of BMWs








Pure porn...




Pictures from today, 25th of july...























Hopefully I will get this car in ONE color in the end of next week...
