After cleaning my housings I noticed some damage along the edges. Please take a look at these pictures and let me know if this is enough damage to warrant new housings or if you've rebuilt motors using housings in this condition and how they are running now.

The front is worse than the rear housing - but they are both damaged similarly. I also noticed that the exhaust port on the front housing has a spot where the steel is worn, possibly all the way through.

Little bit of chatter there...

I think the consensus is that if the plating is going, then they're no good...but I've been known to be wrong before.

I had one good housing when my motor blew...but I ended up just getting new housings anyway. Better to be safe than sorry, especially for a big build.

 

i'd say, based on the flaking around the exhaust port, that the housings are on their way out. if your budget permits, get new housings.

 

if those are in fact S6 rotor housings then they must have a ton of miles on them, chrome flaking to that extent warrants replacing the housings.

 

The one with the chrome flaking around the exhaust port is definitely a junker. The other one is so-so - might be worth using for a budget rebuild, but if you want a nice motor I'd get something better.

Just noticed this on my intermediate housing:

 

IF that is a large chunk of chrome gone around the exhaust port, that's the first time I've ever seen that happen to any 89+ rotorhousing. That type of flaking is usually reserved for the older 85 and prior housings with the weaker coating. I probably wouldnt use it, even though the chrome surface condition on the exhaust "area" doesnt have anything to do with how much compression the engine makes. It could be used with little consequence.

The rest of the wear and surface are normal of any rotorhousing with more than 50k miles. Its not desireable, but it is normal, and reuseable. If housings like these were used, you could probably expect 110-115psi of compression depending on the rest of the build specs.

 

I would not use those housings if I were you... play it safe... unless you don't mind openin' up your engine again and very soon... pm me i'll get you good cheap housing

 

that sucks that the coolant ring channel broke out on the intermediate housing. it should be cheap and easy to find one though.

as everyone else has said, i wouldn't use those rotor housings in a nice build.

however, don't toss them yet. don't forget that there are companies/individuals out there that are recoating housings (ceramic and some i have seen are using chrome). if the coolant channels are in good shape and there is no warpage, then they would make good cores for resurfacing.

 

who resurfaces housings with chrome? I havent seen anyone other than JHB do it.

 

Pineapple, I believe, is resurfacing with chrome. Could be wrong though. They mentioned that they were starting to do it at a seminar they had a couple of years ago.
