I recently installed an oil catch can on the pcv side only. Since the catch can went in the engine will not turn over after a short trip (3-5 mi or so).

If I drive 20+ miles the engine will turn over no problem.

Judging that this symptom began after the catch can install. Would this be crankcase pressure related? Or a completely separate issue?

FYI Im currently running 2 pcv valves one at the stock location and one on the return line from the catch can near the intake manifold. The idea was to not pressurize the catch can and long lines.

Mods are
Cams, springs
Stock turbo
Full exhaust
Tune

Any ideas??

Thanks

 

Do you mean the engine won't start or won't crank. Won't turn over means no crank - the engine is locked or the starter is broken.

 

The engine cranks, battery and starter are fine...

 

Murphy's law says it's to do with the last job you did on it.

Probably ALL of the jobs.


Pulling the plugs out is always a good start.
Take photos....post them up.

 

maybe put it back the way it was and see what happens?

 

My guess... during the install.... you did something else.
Usually from my experience 98% of the time
