So, I have some housings but I'm not too sure if the flaking is acceptable. Can someone chime in and let me know if they're still ok? These pics aren't the best. My cam sucks ****.

That's all I needed to hear. Thanks for the clarification.

 

It's not the flaking, thats acceptable by most standards. Its the entire chrome sleeve scaring chiping away on the lower portion edge of the housing, it is not uncomon.

That was the portion that I was questioning.

 

I can't tell jack ish by looking at your pictures even on my 21" widescreen monitor. Based on what you did circle I would say certainly not.

Looks like someone used some rotaryaviation apex seals on the last build...that, or they had a coolant seal motor that they let water sit in for too long.

 

My cam sucks. The resolution is horrible. I really need a new one. But besides that. I guess I got my answer. Thanks for the speedy reply gentlemen.

 

RA seals can do that?? I knew that they were sketchy, I didn't know they were that bad.

 

ra seals < oem seals

 

Is there a difference from the front housing vs the rear housing other than one is stamped F and the other R?

I read there was because of the EGR ports, but I can't see any differences at all between the two housings.

Does it really matter when rebuilding an engine.

I have two motors and out of the two I was able to salvage 2 good housings. They were both stamped "R" for rear. I've been told that the engine may work but may not pass emissions

Both motors are S4 13bt's

 

use 'em

 

if you swap the housings the motor will run fine however the egr ports will be blocked= no passy smoggy

 

All you have to do (even if you want to pass emissions) is plug the one hole and drill out the other side. Look at your front rotorhousing and notice which side the passage is drilled on. The rear housing will have it drilled in the opposite place.
