S52 finally!

[parkerbink]

Until today I had no misfire. 2&3 are misfiring after I replaced the oil & filter. Leakdown tester came, I'll test tomorrow.

The SC has its own oil cooler system.

Just began trying to do the leak down test yesterday & my 12 year old compressor died.

Picked this up today.



Tucked away.

[parkerbink]

It's official, motor is toast. I'm soooo thrilled.


Extraction has begun, I'll disassemble it once it is out.

What tune are you running?

[parkerbink]

First Active Autowerke tune. I never got over 5.5lbs & never redlined. The motor was already going (IMHO)

[parkerbink]

On the way out.

[parkerbink]

It's out, I'm freaking dead.


The clutch, flywheel & pressure plate look very good. I'll be getting a new clutch & pressureplate.

Nice work 💪

Going to use a lightweight flywheel?
One data point: I have a friend with a supercharged S52, and he says a lightweight flywheel drops the revs too fast when combined with the SC drag.

It's probably personal preference though. I always go for the lightest flywheel I can find, which was a 7.5lb RHD unit that's behind my M52.

[parkerbink]

Thanks, I'm leaning towards using this one as I had no intention of this job & want to spend as little as possible, also, it's a street car so drivability in traffic is a concern. I have not gotten that far, right now I'm focused on finding out if I need another motor.

My guess is ring ends touched breaking ringlands.

Doing another "Stock" 2.8 build?

[parkerbink]

Except the Viktor R (they are crap) gasket I see no issues.

Doing another "Stock" 2.8 build?

S52 cams, otherwise stock.

[parkerbink]

Here are a few more, WD 40 in the head to see if it's not sealed.

[parkerbink]

Mystery solved. Piston #3 has a crack.

Looking for M54B30 pistons, rods & a crank, going 3 litre stroker.

[parkerbink]

I paid a down payment on a fully rebuilt S52 last night, should have it in 2 weeks.
