Gordon, at about 1 minute in, look at the main bearing shells.

 

Have you ever had to do that?  I add 2 holes on the cap side, and they

seem to do just fine.

 

The quality of the aluminum castings is very.... British...

Also, just before the injection pump is set, stop and look at where the coolant is piped in, the third freeze plug hole, via a segmented elbowed welded tube.

Neat video, Gordon.

There's a 'recipie' for adding holes to various main bearings to help evenly distribute the oil across all mains and rod journals; the lore - as I've heard - is the pattern was developed by Korman. I make those mods to every M10 race and performance engine.

 

At the 4:00 minute mark I dig the CCR on the radio (and later, classic German music). -KB

I can't say who started the extra holes in the bearings. I do know that Mike O'Hara was building race

02 motors in the late 70's. Mike did my first ITB motor with the extra holes and I have been doing

the same since then. G

Hmm.  I had not seen that many before.  But maybe I don't spin fast enough.

 

Great video, btw.  Marc Surer- a name from when I was a kid...

Mark,

 

take a look at the guy with the glasses sitting on the left at around 0:25 in your video. That is Mr Kaerner whom I´m still trying to persuade to get me in contact with Mr Schlachter you´re searching for. Listen to his strong bavarian idiom while he´s speaking, really funny.

 

He was very excited to meet again with all the former BMW Formula 1 personalities while dynoing the rebuilt engine. I think he told me during a phone call that even Paul Rosche (Nocken-Paule) was present in Buchloe. To him (Kaerner) that was a real nice reminiscence back to his younger days when he was already dynoing the original F1 engines at Alpina in the original times. He once has shown me quite impressive contemporary pictures from his private collection when I paid him a visit at his home - bellbottom jeans, long hairs and muttonchops and the still red-hot header on the M12. Sorrowly he didn´t allow me to make some print copies or scans.

For the event shown in the video he was joking around a bit concerning the "fearful BMW pussycats" because they didn´t allow to go for full boost with the turbo on the rebuilt engine, he had to stop at a point that he only considered as "upper midrange" of the possible power output.

 

Got your email and will an answer a bit later on concerning the Tecalan fuel lines.

 

Best regards, Lars.

The S14 bearings come predrilled which is what I use.. Jeff Ireland might have them too... Its easy, if you PM me I will scan the Korman pattern and send it to you.  Mark
