Default PCV = SMOOOOTH



Did a new PCV and gatorback belt this afternoon. Aftermarket exhausts on 3800'* seem to be very crackily, atleast without a resonator. After installing the PCM i get no crackles, and it seems to rev quicker, and rev down quicker when i get off it.

Might be some power as the pressure in the crankcase is correct. And it'* EASY on the Vin L engine... No tools needed (cept to maybe fish out the valve).

Belt was easy too! 5 minutes! After someone bothered me asking if I needed a jump...

No whine, i'm still getting my low RPM, Low speed whir i guess. After the engine'* been in an open loop for a long time, and i'm just cruising around 10-20 i hear a lil whir when i give it easy gas..

I replaced the belt in my mom'* '95 with a gatorback and it sounded like she had a jet engine under the hood !

PCV, pressure control valve i believe. It regulates Crankcase Pressures, so you don't have too much air under the pistons, or not enough... Seems to helped out some by getting back some power as well.

$3.
