I have been fighting this problem since months and finally it solves.


As i promise to take some pic's of Catch Can:



.

To collect oil from catch can just disconnect hose from bottom and u can see a red color lever just turn down, in my case got some drips of oil not much.

Just remember i connected both Hoses coming from both valve covers to bottom of Catch Can, and Hose coming from intake manifold connected to top of catch can.

Top of Catch Can= Intake manifold hose +vacum canister hose (connected as Y shape underneath of TB as shown in pic).

Bottom of Catch can= both hoses from VC's + hose from TB (there's T connecter at tB area and T connector at bottom of catch can. Hope this helps this is the best setup i got and car runs awesome and holds vacum steady at 17.5 hg). Iam very happy with this.

Catch Can plus NEW valve seals just on #1 and #2 cyl (causes oil plug foul), both these together solved my oil consumption issue. Now i can sleep better. Many thanks to pete K and his friend Chris who actually replace Valve seals. Perfect and finally hard work pays off.

Many thanks to pete k and his buddy (now my buddy) Chris (a 9 Sec camaro).

Glad to hear you got it worked out.

Drove only 400-500 miles (this includes drag racing too) checked oil level before and after, result = 0 oil consumption, It used to drink 1 Qt of oil every 500-1000 miles.

Your an artist.

Did the oil catch can catch any oil after the 400-500 miles? Or is there virtually none and the valve stem seals were the major culprit?
What kind of oil rings do you have on your pistons, low tension or standard? Sorry so many questions.

Slalom4me

Are the heads still the Dart 200's?

Do the LPE valve covers have rectangular oil separators inside
like OEM covers? If not, were the Moroso 68772 PCV Grommets
that also act as separators already mentioned as a possible way
of helping?



I wonder whether it is feasible to mount your separator high enough
or plumb it in a way that accumulated oil will return to the sump by
gravity?

I still dont know what rings, the only thing i know its Speed pro moly rings, low tension or standard. I called the builder but he forgot now its been a while.

After 400-500 miles yes i did unplug hose from bottom of catch can, found probably 10-15 drips of oil collected, but i guess its normal, just keep in mind during this 400-500 miles i did drag race too made 6 runs on that day, so i guess valve seals and catch can both together improve perf and oil issue,

Also i used to have 2 PCv valves instead just 1 on passenger side, now i corrected that at the same time. U dont need PCV valve on passenger side.

Plus i hooked both hoses from VC's to intake manifold, observe near TB.

Steve u might try this, is ur plugs getting fouled?.

sami85L98

Slalom: yes i still have same Dart 200 heads,
Lpe VC's: are u referring to baffles?. if yes than it has baffles inside just like factory style,

I dont use moroso grommets, i bought from Last detail Stock style grommets and pcv valve (only one u need).

I dont know if i can raise catch can up more, thats the best location i got. It was a tough decision where to install this one. Infact it came with bracket and H/W but cant use, so i install using bigger tie's holds pretty tight and firm

I have heard people sue this breather too, as it is a oil seperator. http://www.partsamerica.com/ProductD...tnumber=B23165

My plugs arent fouled. I am going with a catch can, here it is.

Who buil tthe engine. Mine were JE low tensions Plasma moly's.
I have one PCV valve in the intake, as it is an LT1, and a tube coming out of the opposite side of the engine going from valve cover to throttle body as this is where the PCV system gets fresh air.

I've tried the moroso baffled gromet, and wasn't happy w/results. I am using a Billet Specialties product that raises the inlet for the hose with the pcv inside the assembly held in w/a snap ring(other side matches but empty). This allows some (very little oil) to sit in the top cup area and not get sucked into the intake. (you can see them in my pics. )

I dont know about moroso grommets, its new for me, learned something new, but let me tell u, this oil issue/oil plug foul whoop my azz.

I tried different spark plugs, infact always stock 2-3 sets of spark plugs as i was replacing #1 and #2 plugs pretty much every week, now no more.
Did comp test: mini 192 and max 202 perfect.
Did leak down: Less than 5% all cyl, i know **** on motor.
Did fuel pressure: bought so many tools to test FP, holds pressure .

Ignition: bought couple of whole ignition setup inorder to solve this issue.


All to all i might have spent atleat 1000 to just detect this problem. thanks for all who appreciate. Just sharing my exp.

sami,

What are your ideas on why the stock crankcase ventilation system wouldn't accomplish the job on your engine?

sami85L98

Well its 383 not a monster motor but still bigger than factory 350 with beefed up cam/head/intake and other mods, plus hard driving, racing,
all these leads to upgrade to ventilation too, people dont pay attention or spend more on this mod b/c u wont get extra HP, and so the products available like catch can, electric evapotaors, blah blah.....i guess u need these when u want to hit the pedal.
