is there any way i can check the operation of the pcv valve without all the drama of changing it? the reason i ask, is my v6 vt has a code 36 i cannot locate. the engine was replaced (not for this code), O2 sensors replaced all plugs and leads no manifold or injector leaks. no tb leaks or iac, tps or dirt issue there egr valve works ok (tested these parts with tech II). no hose or egr pipe leaks.
the car idles a few hundred rpm high. then when the fan comes on, it sets of the code 36 (vaccumm leak). it also flares up to nearly 1500 rpm then back to 200 rpm too high again, in park, after this code happens. the mechanic i have looking at it installed the lpg system (oh, its duel fuel ). they are thinking its a tossup between the pcv valve, the pcm, or (and they suspect this mostly and want to work this next time) the wiring loom. the reason they said they suspected the wiring loom is, that they had to swap the injector wiring from one bank to the other side to get the car to run on petrol (before i replaced the motor prior). i guess they are thinking that the wiring change is stuffing with the pcm (can they check the entire pcm funtionality with a tech II tool also?)
anyway, hoping there is some simpler test i can do to check the pcv valve...... maybee blocking a pipe to the valve or something similar. that could at least eliminate that possibility, and i would feel more confident in their wiring loom idea. if i pay for another $300 job and it doesnt fix this ill sceaaammmm!!! (in my mind )
i hope someone knows some test trick anyway.
cheers all :blah blah:
