So yeah. I finally got the car out of the garage today. I didn't even plan on leaving the neighborhood, I just wanted to drive her once around the block to see how everything was running. She had no hood and was extremely dirty, nevertheless it felt great.

I was in second gear and wanted to see if I got the vacuum lines and turbos in right so I gave it a little gas only hitting 4 or 5 psi. The exact moment I hit 5 psi I heard a huge pop from the engine bay (i know a backfire when I hear one and this was no backfire). The idle still seemed smooth and the map sensor is still connected.

I am under the impression that if it is an apex seal, it would idle like ****. What can I check besides obvious compression test?

damn man sorry, i just took my single turbo which is no where near ready out for a spin and its havin all kinds of drivetrain alignment issues (I THINK, didn't check my bushings, though)

Rebuild coming your way or what?

Black1993rx7

yeah. the good news is that after I rebuild the engine, I will have rebuilt everything (transmission, turbos and engine).

Going single huh? Let me life vicariously through you until I complete my rebuild!






Seriously.

What does your boost/vacuum gauge read?

If your idle is still smooth, i doubt you blew a seal. You'll know right away at idle if you lost an apex.

Now a cracked apex, thats a different story. Ill let the vets chime in on that one.

Will they crack if they weren't warm enough but got too much pressure?

Black1993rx7

Car was completely warm before I boosted at all. ALWAYS!



Anyway, one of the intercooler pipes popped off, thank god. Scared the **** out of me. Atleast I'll be able to hit 10 psi before a seal goes.

ive had the IC pipe slip because of too much oil gettin past the turbos and eventually the seal became very slippery. a loud shotgun like sound.. what did yours sound like?

Black1993rx7

yup. a shotgun would best describe it.

Hit me up when you get your car running. I would like to take a look at it. What side of town you live on?

No.

These motors don't blow that freaking easily guys . As soon as I read the first post I knew what had happened.
