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

[EthanolTurbo]

A very simple mantra to follow is "if it ain't broke don't fix it". With time all those bullshit ass "upgrades" come to light as being shit ass upgrades. Take the radiator for example, with people wasting their money on csf garbage only to discover their car overheats and paying for the privilege of it doing so. No wrong has ever been done by sticking with oe parts. Conversely look how much it costs people who cheap out on parts to save a buck and it causes long term damage to their engines unknowingly, or, eventually knowingly after the fact the damage has been discovered. Even cubieman had an issue with a beisan oil pimp disc which was a 30+ page thread in and of itself.

Yeah and the stupid CSF radiator adds 5 lbs of front weight on a car where you want every lb of weight off the front.

I don't disagree with the above, my point was that the issues of the plastic impellers, that was resolved 20yrs ago, still pushes people to be scared of plastic impellers to this day.

And a BMW pump has a limited lifetime warranty through BMW. Covers the cost of the part for the life it it fails.

I’ve had to learn this lesson a couple of times…🤣

And it’s possible the radiator was one of those lessons. And the worst part is it even costs more than the OE part.

Only the person that had removed the rocker rods (to replace the rockers)

That's the thing - in my ownership I've never had anyone touch the rockers - so what's worse, a shop forgetting to replace them? or shops not catching they were missing in the past 5 years of my ownership? 🤦♂️

[Anri]

One of the rocker arm has odd damage and was replaced with
a good one I have in stock.

Moving forward

[Anri]

The chain cover was cleaned to like new
condition.

The crank snout was cleaned as well from the old
grove.

New seal was installed and pushed in deeper so that
on the next crankshaft seal replacement the seal can
will be installed 1.5mm less that means the grove will
remain after the seal not before the lip of the seal!

New Chain, all new guides are already in.

Head is ready to be installed.

They are in the very back of the head, while I agree it SEEMS like this should have been caught I think its unreasonable to expect a shop to do so without being in the affected area and a valve adjustment isn't "being in the area" IMO.

What do you do to counteract the potential failure from mixing and matching follower on cam lobes?

Hill,

With a risk of having people jump into an argument
I must say that it's not a problem at all as long as the
rocker arm is in a good condition. I have done it many
times. On every S54 I rebuild I do polish the rocker arms
before I install them back.

I'm learning here.
But I think if the cam lobe and the new used follower are polished then they should be paired safely.

I can't see the old groove mark by the oil seal on this pic; did you do any polishing or only cleaning? I'm surprised that the oil Teflon seal didn't cause any wear on the meatal sealing surface.

I've done it before too, I laid out all my concerns and the customer wanted to roll with it... It is still running but certainly made me nervous.

Sapote,

Thanks for your replies.

This is cleaned surface already.

Bellow is how they look like before I clean them up

Gents,

I am wandering why people still use silicone
around the engine ?

I have seen silicone on water pumps, cams
sensors, water pump tube etc..

In my shop I don't have silicone. I use only
compounds and guarantee no leaks!

Head is on, moving forward.

Because it is in the TIS instructions to use Drei Bond 1209 silicone sealant in those areas you have pictured.

Slideways,

Do you make a difference between the Drei Bond and RTV silicone
used in the pic as everybody using ?
