Stevenkan7: ok
Stevenkan7: its not oil starvation
Stevenkan7: the assembly wasn't balanced
Stevenkan7: either wrong counter weight or something is throwing it off
Stevenkan7: because oil starvation will cause the entire assembly dry
Stevenkan7: and damage everything
Stevenkan7: i thought it was the entire motor
Stevenkan7: but what you're seeing is an unbalanced assembly
Stevenkan7: either the rotors were off balanced
Stevenkan7: or counter weights were wrong
Stevenkan7: the hot spot on the side housing was cause by the bad rear bearing
Stevenkan7: the rotor was touching the side housing
interesting that steve kan says this, and rob discovered my flywheel was heavily distorted (factory defect)

What were the symptoms of the flywheel "defect". A warped flywheel wouldn't cause an imbalance it would cause the clutch to chatter while engaging.
Did you use the correct counterweight? I agree with Steve, if the bearings starved your turbos would have starved to. Everything in the system would be starved.

Are you sure it's the o-ring banzaitoyota?
How long have you had the motor? modifications and type of use?
I'm starting to feel vindicated for buying a Malloy reman instead of getting a motor clear across the country from rotary rebuilders in CA or Oregon, inasmuch as I just wanted a reliable rebuild without porting.

yeah, i had the upgraded water seals, they looked nice
i just called joel and he said hie'd measure my counterweight and both rotors, maybe one is off spec
we'll see

Waiting on ROB to call me back, he's "BUSY"
Not sure what seals ROB (or however was assembling his engines in June 2002) used. This is an email telling me the highlights of the engine I bought:
"John, we are working on more info for the website.
Thanks for the input! The difference between the 2yr
vs. 5yr is the 2yr is a quality replacement rebuild.
The 5yr has in addition to the new rotor housings,
apex seals, bearings, oil rings/o rings, spngs etc of
the 2yr: spark plug eye brows machined for ease of
alt. plug use(like cold race plugs), new corner seals,
side seals, cryo treated oil control rings/bearings,
stage 1 oil mods, port cleanup, applying of thermal
barrier to the plug hole(to help prevent cracking).
These are the big highlights."

haha, that means he's in the porting booth...doesn't like to be bothered when he does that
maybe he's working on my ports
seriously though banzai, sorry to hear that....keep us posted
perhaps one of your irons failed, in that case, it's not necessarily the engine builders *fault*, but it would be warrantied

I will, I am just disappointed I "apparently" have one of the "bad apples" to leave his shop in the summer of 2002. Plus I am missing the LAST AUTO-X of the season next week.

I have NO question about the components that went in it. BUT: IF ROB knew he had a problem with a "certain" employee's assembled product during a certain time period, I think he has an obligation to let his customers know and not wait for the problem to appear.

eh, i disagree slightly
while you are obligated to know there was a problem, etc, you should have been notified, etc
i'd say from his perspective it's better to take the gamble and eat the rebuilds than it is to worry people for no reason
it's not like an assembly line where one machine screws up the same thing over and over again and they can isolate the problem
if it's one bad builder all together, the problems can vary and the only way to fix the situation is to prioritize the re-rebuilds and warranty them

I was worried when rumors of the rash of bad engines surfaced. Now my fears have been realized.
here is a video from 2 weeks ago when I started to supect a problem.

but i ran the racing beat flywheel, which had its own counterweight.....
joel just called me back, all rotors are within spec, and counterweight matches 3 others they have there
rob is going to call me tomorrow, he's uber busy today- so we'll wait

A quote from a private email I received talking about Evan's coolant.
"Evan's is absolutely worthless for a 3rd gen. Only benefit is high boil point by which time you will have destroyed a rotary. All other claims are either misleading or fraudulent depending on your viewpoint (used to work in the process water chemical business and hold a Ph.D. in science- not guessing)."
