Chuck, in away has done us all a big favor identifying
this

mode

of engine failure. I think we should all send him a
check for what ever we can afford to help him pay of his

engine over haul. He is going to need a

new rotor

housing and a new rotor for sure. Probably at least one
new

end

housing.

What is your mailing address Chuck?

    It's going to take time and money to examine damage and
come up with a fix would like to donate too.
    Let us help you (help us) the rotary engine is evolving,
stuff happens in the process and this seems to be the forum to

find the answers.  thanks for all the effort everyone, doc
maglaughlin

 Thanks for the offers, but I am in this with eyes wide open, if

anyone

finds my experience valuable, just consider it a trade for all
the

tips

and valuable knowledge I get from everyone on this list.

Here are a couple of photos of the damage. The center housing
was untouched, the end housing had a small amount of metal
displaced at

the

edge of the inlet port, may be repairable by enlarging the
ports. The rotor and rotor housing are history. It was a new
rotor housing, rotor and end housing was used parts when I built

this motor. I had about 80 hours on this motor, with Paul's TES
oil O rings looking like new,

will

likely reuse them.

Chuck have you notified Pineapple Racing about this failure? The
least they could do is help you out with the rebuild.

BTW it far, far better for us to contribute to your engine
rebuilding cost than to the Chuck Dunlap Memorial fund :)

Chuck, let me know if you're in need of any hard parts.  I may have
some here that you can use for your rebuild or can find them easily.
Also, great news on the TES oil control ring
o-rings; I've been waiting for a practical, positive review to come

out.

They
should be fully re-usable.

Do you have a picture of the end plate that got nicked near the intake

port? I'll tell you if it can be removed from porting work or not.

7/20/03 I emailed Rob Golden at Pineapple Racing a description of the
failure, no response yet.
I have already repaired the end housing damage, it look OK to reuse. The
only photo I took was the one previously uploaded,
endhousing_rotor_damage.jpg it shows the damage pretty well.
I have ordered new rotor housing and seals from Mazdatrix, should arrive
next week.
I have always had a spare motor, I can use a rotor from that but I would
like to come up with another rotor to keep the spare motor parts intact.
Brian, can you find a 86 NT rotor for me?
Thanks

Chuck Dunlap

Some of us are profoundly upset by your engine failure and near death
experience. It would make us feel better if you would allow us to help
you out with the rebuild.

An 86 Non-turbo rotor?  I believe they're the same as the 87 and 88 ones,
correct?  9.4:1 compression?  I'll see what I can do today.  What weight
code
range do you need?

Chuck, I have a 1988 N/T rotor is good condition.  I'll not be using it if you interested let me know.  No charge you pay for
shipping.
