so, ive been replacing stuff this past month, getting ready for winter, and as ive been replacing things, ive noticed oil consumption going up, fuel mileage going up a tad, and no more coolant leaks

 

ive been getting alot of blowby/pcv smoke lately, and slightly more smoke show on long right turns, but in the last 2 days its gotten worse. its gone through 2qts in the past 1k miles since ive replaced a bunch of things.

 

the underside of the car is bone dry for the most part, only evident leak is a bit from the VC gasket.

 

 

things ive replaced in the past month:

 

oil filler cap (i got tired of the grime all over the filler neck)

cam seals

front crank seal

oil pump seals and mickey mouse gasket

pcv valve (autozone, should i go get oem?)

pcv hoses (no, i don't have a reroute kit yet)

timing belts and pulleys

 

 

it smokes worse than usual on right hand turns, and smokes under load going uphill(that just started today) and i noticed quite a bit of oil on the driver side pcv hose, passenger side has mild residue.

 

so, my thoughts, either the pcv valve took a dump, or a clogged cat maybe? or do i truly need the reroute kit? or is it my worst fears (rebuild) at the start of winter when i need this car the most?

 

 

also, why do they have both sides connected? how do you even apply a vacuum to the crankcase if it has a 1/4" or 5/8" hose leaking atmospheric pressure to the system? could anybody fill me in on that one?

Hey man.

 

Do a search on the PCV system. I seem to remember GD covered the subject pretty well.

 

I had a similar issue with my PCV system. the manifold was dragging oil through in high vac situations. But not when on the throttle.

 

Hopefully this is the issue. Other causes could be worn valve guides and or rings.

 

Good luck

i've been searching this for the past 48 hours, and the problem is that anybody with a problem close to mine never follows up on their thread and its left with no answers.

Wish I could help you, but don't get discouraged. Somebody will chime in with something helpful eventually, just gotta be patient for the gurus to take notice.

ok so i went to check a few things on the car today.

 

 

manifold vacuum is ~20"hg at idle with the tiniest bit of fluttering in the needle (less than 1"), and strong vacuum present at the pcv valve. the little hose was clogged so i cleaned it out with a coat hanger and brake cleaner.

 

 

also, ign timing was at 24* (last time i set it, i unknowingly had loose timing belts to throw it off.)

 

is it possible when i did my timing belts i ************ed up putting the dipstick back in and now its not all the way in and im overfilling it?

okay ive gotten it taken care of.

 

i made my own reroute kit with pvc T-fittings from the hardware store and some pcv hose. i also picked up a pcv valve from the dealer, and ran some seafoam through her. oil consumption has all but gone away except for the leaky valve cover gaskets.

Surprised nobody else jumped in here to offer assistance, but glad to hear that you managed to somehow take care of it yourself. Persistence is key with these cars lol

yep, persistance is definitely the key with these cars...

 

also, i updated this thread for others who might have the same issue and ran into a billion unresolved and unfinished threads. i hope more people can do the same for the old gen community so that we can keep them on the roads and out of the yards.

okay, so the oil consumption is not gone... am i missing something here?

 

 

i checked underneath the car for oil leaks, i'm not getting any leaks other than the valve covers.

 

 

is it possible for the valve covers to leak so bad that you go through a quart of oil every other tank of gas (~6-700 miles)??

Just to clarify, you're noting the smoke coming out of the tail-pipe?

Does the car ever sit long enough for you to tell if it's leaking only while running?

i let it warm up usually when im about to leave work, and i don't have any (that i can see) leaks while running. only oil spots i ever see are directly below the valve cover seam. i just ordered the valve cover gasket kit.

 

i don't really notice any smoke out of the tailpipe, and i only smelled oil burning when i didn't have a pcv reroute yet, and hit right corners hard enough.

 

so, the question is, should i start thinking of a rebuild when it gets warm?

valve guides and or rings is worn out...

try check compression tester.
