THE M3 IS GETTING THE ANRI BUILD TREATMENT - Blown headgasket to build thread

[sapote]

The oil pump disc remained with oem size holes. The welded drive pins are
lose in the hole which is resulting rattle at around 2000-2200rpm range from
both camshaft back/torque operation.

I thought the driving pins on these non-OEM hubs are larger than the stock hub pins to minimize the plays.
Maybe the Tig weld is to prevent the stress-riser at the sharp 90* angle at the base of the pins compared to machined hub?

I am always intrigued why some engines have such a dark brown staining inside, while others look very clean like bare metal.

Cobra,

Thanks for your comment.

It's very easy.

Cars which started life in freezing temperatures
do not do well with that. That means the oil from
freezing temps will heat up to 210F and back again
to freezing for min 6 months of the year for the passed
15-20 years let say.

Every single engine I have worked on from cold
States they have that without exception unless
the car is driven only in summer time.

Even if you change the oil every 2000k miles one
will always have that black oil burn deposit.

Say California cars never ever have that heavy black
oil burned deposit.

Anri

Diving in:

Few things to note the Concept applied from whoever performed the service
for this engine perviously.

I always say their isn't a wrong concept by one choosing what to do, but
their is not an optimum set up!

- The exhaust side hub design is very goofy...the biggest downside
of this design is that the hub is TiG welded!!! TIG welding parts is great
because the heat penetrates very deep resulting the parts to warp
for sure. Delicate area/s like the helical gear may/will be affected, one never
wants to have welded parts which are warped. I mean we are talking very
little just few thou and that is all you need to have wobbly part/s..In areas like
let say suspension, roll cage, 1-2-3-4thou it won't make absolutely any difference..

I am sure they will argue till the cows come back from the grass field which
may be months that its not a problem but in my engine I will prefer to have
the OEM or Beisan hub machined from 1 solid piece

- Next, one spent all of of that bloody labor and did not replace the 8.8 cam
flange bolts ?

Moving forward.

Anri,

To be clear this is the fan clutch? From a e36?

Yes and make sure you don't tell anybody.

Keep in mind that if you install the Sachs and you blow up
your gasket next month don't speak negative that it does
not work...Say the car ran for 100k miles with Behr and the
abuse is already done on the gasket...

It's a good upgrade, can't go wrong with that one for sure.

Well crap, I bought a Behr back in 2019. No issues but darn it.

I've never thought I'd be so happy to see the confirmation come in that the head gasket is actually the culprit, and that a fan clutch was the culprit - thank you for the update!! Hoping nothing else is the matter once it's opened up 🤞

Gents,


Let this all begin.

I am a bit crazy and tools like leak down tester and compression
tester I always have 2 different gauges and I always take measurement
with both on let say cyl#1 to make sure the reading I am getting is spot
on and then I continue with the Longacre to test the rest.

I use old school but NOS Made in USA Matco and also
I have the Longacre which shows me the exact % which I like better.

Most people will use the Matco style which shows in "wide window range"
also the increments are in 5% range but I like exact accuracy in numbers.

The leak is escaping between the bores. I confirm the fan clutch is lazy
and I was making a point in other post how the Behr fan clutch is not good
compared to Sachs. I will point again the system works opposite as on the
older BMWs and this is the result from running hot, not overheating but running
hot resulting tired head gasket.

Inline-6 engines, 5-6 run always hot and why you can see those cylinders
suffer the most damage from the rest.

You guys can compare the numbers taken from the previous test.

Regards,
Anri

WestBankM4, 0-60motorsports - Thank you guys, I appreciate it - I have a feeling the car is going to be even better than when I first bought it. Let's see!!

M Coupe - Thank you for the reply man - that's exactly what I went with Anri in the first place. I was thinking to myself like damn it, it sucks that this happened, but I love the car so much I need to make sure it's done right the first go around because I don't want to open the motor up ever again if I don't have to. After weeks of research, Anri was 100% the guy for the job, and local to California as well. I mean the amount of calls we had leading up to the pickup, explaining the steps, answering my thousands of questions, etc. also let me know this guy was going above and beyond. I've never been able to connect with a shop at the level of customer service Anri has given me thus far - needless to say I'm excited for the outcome.

[M Coupe]

Anri would be the man I would be shipping my S54 to as well whenever it may be due for a rebuild/refresh. I hope he keeps doing his amazing work for many years to come!

[0-60motorsports]

Good Luck. Hopefully you get the issue resolved.

[WestBankM4]

It's going to come out amazing man, SUBSCRIBED!

Can't wait for Anri's breakdown.

11.20.23 - Update - Car was picked up tonight!!

After some timing setbacks for pickup, Anri came to pick up the car tonight - It was great to meet him and he felt like an old friend of mine haha - So excited to see it loaded up and on its way.

Plan is the following -
Step 1 is to see what's going on in the motor, double-check the compression and do another leak down
Step 2 will of course be the conclusion of that test, and more than likely the start of the tear down of the engine.

Edit: I wanted to add some things that I noticed about the car that might help others trying to diagnose their head gasket -
- The car started right up after sitting for 3 months, no smoke, nothing, just as it would usually
- Regular driving felt totally fine
- While getting onto the highway on an on-ramp, I heard a single ping noise in second gear and third gear, come from the engine while Anri was in the car. One could say this could sound like a single marble hitting the inside of a tin can. He flagged that as a sign of the HG and the sharing compression in each cylinder potentially causing a single detention. I had never heard this before prior to this drive and thought to add it. As Anri has mentioned to me it's really good that I caught it this early without it getting any worse, and this is a clear other symptom of what most likely is a blown head gasket,

More to come as I have updates!
