Saving a S54 From Parting Out.

Cylinder head gasket:

Well, after removing ~0.55mm from the deck height
the stock gasket will not work for sure.

I ordered MLS Cometic, I was not sure why I thought that
they were made differently for each engine and make..

In the Cometic casket design I don't like 2 things......
I made a quick call to Cometic and started asking question
in regards of my concerns and I kept having the same answer
over and over again which was "we never had any problems..."

I was on a cross road to make a decision either risk it or go
with something I feel more comfortable to use.

MLS/Cometic was dropped from the list.

So the choice of mine will remain Proprietary for now.

What were the 2 things you did not like about the Cometic gaskets?

Great work!

Anri, thanks so much for sharing all the great build content and expertise!

Anri,

Where are you located? Do you only take local jobs?

Hi Eacmen,

At present 80% of my engine projects are out of state.

I am in So.California.

Love it Anri!

Thank you sir.

Gents,

Too many engine projects are on the pipe line and had to concentrate
to get this project going on the road asap.

Engine is completed up and smooth running

After the initial start I have my own cup of tea procedure how to
break-in the motor and after 10mins engine was off.

All 6 spark plug out and checked the leak down and I am at "0"
also checking the lash quickly.

Well 0 does not exist !!!!!! but I am getting 1% leak down which
is absolute like how E46M3 rolled out from the assembly line back
in 2000 from Munich.

I have attached short videos on all 6 cylinders to share with you guys.

Again, this is for only 10min of engine break-in. Let the engine sees
1000 road miles and it will improve around 0.2-0.3% so I will end up
with around 0.5% leak down.

I do make sure before the engine goes back to the customer/road
I have great holding cylinder and head pressure. Its not nice the
Customer to check the leak down on its own and check the work
of the engine builder like what happened recently with our member.

Every engine I put together comes with 2 Years Unlimited miles Warranty.

Anri

Anri, What machine are you using?

Hill,

I will sent you PM.


I forgot to mention very important point, the concentricity must be taken from
the 45 degree angle not the top/last as I think the guy in the video I linked
took.

Anri, What machine are you using?

[Anri]

Anri Thanks for posting his channel, some good info in there even if it isn't specifically BMW. I watched his 3x videos about concentricity and started watching his series about building the BBC, lots of food for thought that can be applied to any engine.

Hill,

I don't know the guy at all it was just quick sample to demonstrate another
CNC-Newen type of a work. Nothing new to me in this machining world
any more...

I personally have done 50+ S54 cylinder heads, not counting the S38
S14, S65 etc.. I personally install guides, I personally hone them, I personally
cut the seat with 0-1" thou Concentricity. My standard is max 1' thou.

On the Serdi web site I watched their video of presentation on one of their
valve seat machine. In few days I will post and provide data in comparison
I have in mind.

Anri.

I don't care if its the machine or the operator. Where is the QA? This is exactly why machine shops and engine rebuilders get a bad name, most want to tell you how their all first rate builders but Anri up in here straight walking the walk.

Oceansize,

Thank you for the kind words. I have noting to hide. Every Engine I build for
a customer comes with massive pictures and notes. To further up the quality
build I am in a process to make mounting hardware so I can put the engine
to do break-in procedure before being installed in the car, or I have option
for Engine Dyno as well.

Anri.

I don't think the NEWEN CNC machine to be blamed, but who set the valve guide as the center with 8 thou off center error

Sapote,

The guide has nothing to do you need to understand how it works and it
will be easier for you see it.(I can tell you got the comment from the guy in the
video and that gave you some food to chew) Again, trust me it has nothing
to do, I wish you are next to me when I am on top of machine so I can explain to
you and show you and then most important is I can demonstrate to you by going
Reverse-Machining...so you can see it with your own eyes how bad it will
go...Remember I made the correction on the same guide....



I looked earlier today at Serdi CNC valve seat machine and they talk about improving
the Concentricity ! Improving concentricity in 2023 ?... I made a video for us here
to share the data and the result personally I can do with the manual machine..Sapote
the machine I use is also Newen...lol
