Positive Crankcase Ventilation (PCV)

[griszi.81]

I bought a car from someone who had modified a Nissan Stanza.

I took it in for an oil change and they got kind of excited and asked if they could use their hand vacuum pump to (see something) about my engine.

the car made a cranking sound and lifted and sat higher on the suspension.

from that point on the car had Waay more power and it idled at like 25 MPH/.

They said since I don't have a valved oil breather cap .. that it was going to loose this.

can anyone shed some light/.. the car is on the side of the road and i think i need to perform this to get it going again? .. thank you..

Hmm, what is the question really? Which exact car are you asking about?

[curtis73]

Umm... no. Just no.

ok..

basically the car jumped into what seems like neutral on the hwy. the only pluses I am thinking are that the gear down shifted as i coasted off the exit i just couldnt get it out of neutral its an automatic. the Transmission fluid was low and i havent gotten it to go into gear since.

Did you add fluid?

Low fluid level will give you a gearbox full of neutrals. They need adequate fluid levels to function properly. But do not overfill them. Check the level with the engine running, as described in the owners manual.

I remember reading that. i think im gonna go out there and try that. i pryed open the crankcase trying to examine or fix something, in haste, causing a pretty significant leak, but i found a good gasket at pick n' pull. i gotta grab a tourque wrench, that gasket.

its good to hear it described like that, i appreciate it. thank you

Is this guy for real, or a kid playing on Mom and Dad's computer?

You don't pry open the crankcase and you don't get gaskets from the salvage yard. I revert back to Curtis73's post above.

ok.. i unbolted the top cover, then pryed it open.

i would have to assume that a salvge yard gasket, is better than that friggin' glue crap at the kragens..

do you mean you are not alloud to grab micro fiber gaskets at a salvage yard.

[shorod]

So you're referring to the the valve cover, not the crankcase?

Many of the new models use only the RTV gasket maker, no cork or rubber gasket, which I suspect is the "friggin' glue crap" you refer to.

I'm not sure what you are referring to as a micro fiber gasket. If you are referring to a standard cork gasket, you do not want to reuse an old cork gasket. Save yourself the headaches and purchase a new gasket from the parts store. In the long run (and possibly even the short term) it will more than pay for itself by preventing oil leaks that will cost you in adding oil between oil changes. Of course all of this assumes you are properly installing the gasket.

A bucket of compression? perhaps?

yeah it wasnt the crankcase.. i think it was what you said or the differential cover? poosibly, or something like that.. its leaking ATF now. i was trying to see if it was burnt.

so ill go with the RTV gasket .. salvage yard is out. thank you for all your help. i was stoked about a month ago to fix my radiator leak replacing the "Hose".. new hose clamps and all. i can change the brake pads but i can't talk shop and i barely know anything.

i was just getting mechanics suggesting new transmission, burnt clutches , etc "but i'd have to take a look first" kind of thing.

thank's you's guy's
