+ you have a compression tester. Rotary one -- home made or otherwise.


Let's talk. Shoot me a PM or reply within. Located in Everett.

 

Or either a block tester or coolant pressure tester. Need help with diagnosing what's going on w my turbo FC.

 

remove a plug from the front rotor, pull the efi fuse, and have a friend try and start the car. It will sound pretty obvious if one of the seals is blown. repeat process for back rotor. You should hear 3 even "pshhh" noises...if it sounds more like a "chugggg" then its blown.

 

Did that w a piston checker. ~93 psi each face both rotors.

 

93 psi sounds allright for compression , what kind of problems are you having?

Went to the track two days ago + she was amazing. 4th 30 min session I forgot to pop the hood open. Came back to a peeing overflow bottle. Vented the cap, the filled her w more water. Coolant temp was good the whole time too. On the way home everything was fine.

Start it up the next day, warm it up, go to boost + nothing. No pulling. Below boost feels normal. I also hit 15 PSI. But the whole time at the track + after, I never had it overheat + never heard a pop (motor blown)


Someone suggested clogged cat, so once it stops being stupid hot I'll put the test pipe back in.

 

Do you have a red FC I think I saw you leaving the track last Wednesday. Nevermind I just looked at your other thread and I was down there the 22nd
