blew my engine
Well sadly my engine blew today. i just purchased the car a week ago and it gave up on me. the guy i bought it from daily drove it and it seem fine. i test drove it and it seemed fine. so today i was warming up my car to take my friend out for a drive. it warmed up to 180ish and the fans turned on. i reved it up and around 7k the engine blew and died. antifreeze was gushing out of the engine. i jacked it up and found the problem. the center intake housing cracked. the crack is right below the spark plugs. its a hairline crack that goes horizontally and is about 3 inches long.
i was shocked at how that happened and that it wasnt the apex seal that died. i havent pulled it out yet. im hoping that the housing just cracked on the outside.
has this happened to anyone? do i have to rebuild the whole engine or do i just buy a center intake housing.

Still got it.

Post a picture of the damage.
Plates being cracked can be caused by binding of apex seal fragments, rotors, plates & housings trying to occupy the same space at the same time, while not meshing (something was out of place.
I've seen a rotor housing break out a 2" chunk in the load zone.

How many miles were on the engine? If it isn't locked up do a compression test before you pull it, then you'll know for sure if it's fuber with a 0 - 0 - x psi reading. What was the compression on the engine the last time you tested it?
Sorry it happened, I've been through it myself recently

I'll take a picture of it tomorrow. It supposedly had 30k on the motor. It has 3mm apex seals and it was a new shortblock. The engine is locked up now. The compression test were normal. Above 7psi on both rotors

If I am reading understanding correctly.. from what you wrote in the 1st post... and that you say the motor is now seized..
Sounds like you had a catastrophic engine failure.. where the rotor internally comes off the stationary gear and crashed into the rotor housing.. breaking/cracking the rotor housing..
I have seen an engine that this happend to before. I broke it down (was not easy to do.. had to beat it apart with a serious hammer) all of the internals were destroyed..
The shortblock was all trash..
You where free reving the engine to 7000 rpm?
Why?
