Test run without exhaust


Recommended Posts

A moment of truth .. I am finally about to perform a test run for my Carrera 4.

I would like run my engine for five minutes without exhaust, can I do it safely? Would it affect my Durametric readings significantly? All other parts are connected, cats and o2 sensors included.

My car has been unused in an ocean ship container and later on my garage on jack stands for five months now. I have performed various maintenance work including IMS upgrade, RMS, tensioners, AOS etc. People seem to have conflicting opinions should one prime oil pressure by cranking engine by pulling coils, spark plugs and C4 fuse out, I think I'm going to crank my engine such way for 8 secs before doing it for real.

I'll soon post interesting video material of wrenching :-)

Running it without an exhaust system, but with the headers in place, will not harm anything other than your hearing.

To get oil pressure, pull the fuel pump relay and crank the engine until oil pressure comes up on the dash. Plug the relay back in and you are good to go.
