About a tank of gas later my oil catch can....

[Karl]

About a tank of gas later my generic oil catch can has caught the following. Look and you will see the trapped oil. Not bad!

[scottfab]

Hard to see what the scale is. How much would you say that is?
Teaspoon? Tablespoon?

[Karl]

At least a teaspoon and a half. Oil catch can is from Ebay. $16 & free shipping. Time will tell if it is a good value or not.

This picture shows the best shot. I brought the can inside and as it warmed up the oil began to settle at the bottom.

[Paul Workman]

I would say that is not bad. Just one less teaspoon less oil to cake onto the secondary valves and foul the plugs.

$16??? Dayam!! Do tell (please)... I won't even admit what I paid for the Moroso unit I just bought this past winter at Winner's Circle (in Joliet)...[sigh]. (However, I was told mine would also lick my genitals too, so maybe there's that - it better for what it cost me!!)

What a deal. Just ordered one.
This is one of those mods I've been studying for years.
It's easy to back out and offers a real benefit.

Glad I waited. What a deal !
Thanks for sharing.

No problem. I mounted mine in front of the ASR assembly and used some simple zip ties to strap it to the hard a/c lines. I also have the clear tube facing the opposite direction of the exhaust. So far so good.

And for the record this is about 3 tanks of gas and not one! I remember getting this unit last summer/fall when it was still hot outside. Needless to say I am satisfied with results and the cost.

Anyone know what filter to use on this catch can when needing replacement?
I use this catch can and the one issue I ran into w it was a vacuum leak. At the bottom of the glass was a pull valve that would empty out the oil from the bottom. After a while it stuck open creating a small but perceptible vacuum leak.
Another one of those things that I discovered while just looking at stuff and noticing the idle smoother when I closed the valve manually. Now it's JB welded shut.

Dominick, do you use the same catch can as I do? There is no filter in the one I use. It is hollow. I have considered stuffing stainless steel wool in it but I see no reason why. Plus i'm paranoid about the engine sucking in some loose material.

PRv8, I bought one without the filter media as well but put a short down tube in the inlet side to force the vapors to travel downward first. then I added stainless steel Brillo pads as a medium for the vapors to travel upward thru the SS pads to the exit port. I believe the pads will capture a little more of the oil as it presents a surface area for the vapors to attach to. I haven't done any driving yet but will soon as the weather is getting better. Good stuff on this forum...:)

[Paul Workman]

This is the Moroso oil separator filter section; basically some course stainless steel wool in a separate internal container.

Really nice unit - and better be for $130.

[Karl]

Paul that makes me feel better. When I get my car back I will stuff it with stainless steel wool. I picked up some from the hardware store the other day.

[chriskinzel]

I mounted my rather stout can under the left headlight. It took 3 different installs to get it low enough that the light wouldn't hit it. I moved the 'vacuum ball' over by the horn. Haven't driven enough to see if it has caught anything yet. Mine has a dip stick.

Just my opinion but that thing is almost too nice to hide. Some braided line and A-N fittings would really set it off.

[USAZR1]

Looking at some of these on ebay,there is a good selection to choose from at a wide disparity in cost. Maybe it's just me but I really don't care for the cans with sight glasses.

Here is a picture of my 'stout' catch can.

Yep. Purdy it is, I guess.

I'm thinking I want to avoid cluttering the engine bay or the motor as much as possible: tough to improve on the LT5 appearance as it sits.

My thoughts wander to intercepting the junction between the rubber PVC housing and the vent pipe, but using as much of the original vent pipe as possible, so-aZ not to alter the stock look any more than necessary. (Neither side of the bay is exempt from consideration, either.)

[scottfab]

Great location. I'll be doing a black paint rattle can job on mine and hide it in this location. Looks like it was designed in that way. Good job!

My tanks has a dip stick. When it's time to empty, just unscrew the bottom half and dump. No oil anywhere.

I don't have my car now so I can't take pictures. The picture I posted earlier is the best shot I have.

Btw check with the seller in Ebay they have other colors. I like the purple, plus you can barely see it.

Mine has the screw at the bottom also for easy oil removal too. Only thing I plan on doing is stuffing the catch can with stainless steel wool.

[Karl]

Here is a video I took yesterday of what my catch can has accumulated so far. I am guessing around 1500 miles give or take a few.

More would have come out if the can was warm. I also spilled some out the top before shooting the video.

I removed the clear read tube (John Guest Fitting) because it started to leak. I also stuffed the catch can with steel wool.

One other thing I noticed is the car does not consume oil like it did without the catch can. Anyone know why?

Karl,

I'm going to guess that the larger catch can reduces the crankcase pressurization which would force the oil into the cylinders. IOW, its breathing easier. That's the reason I decided to try a new one.

[Schrade]

I'm getting slightly more blue puff at startup.

Last O/C, I was gonna' do a double change; put in house brand 30wt syn, and was gonna' run a few CL cycles to move it through, then did a second drain fill with the cheap syn, and it's still in after 75 miles, 6 weeks.

Seems like the lighter stuff is more likely to go into vapor phase???(and pull through PCV plumbing / Separator as well )

[Karl]

I relocated my catch can to under the headlight and just drained it from this year's driving. So far it has caught lots of oil.

With the can further away and the length it has to travel back to the throttle body seems to really influence the amount of oil it has caught.

Every ZR-1 should have one of these.

I wish there was an easy way to let it drain from the catch can back into the sump. I guess that would require a new fitting in the oil pan. Maybe not to difficult to add.

And maybe a check valve to prevent the oil from flowing back into the catch can. Sounds interesting.

[RussMcB]

It's pretty common in race car oiling systems to have the catch can(s) higher than the sump, so they'd just drain via gravity (the same way 'used' oil in engines normally returns to the sump). I don't think a check valve would be needed.

The biggest part of the job would be adding one or two fittings to the oil pan. Kind of like aftermarket turbo systems have for returning oil from the compressor housing.

throw that oil away. it's got lots of moisture in it and not worth saving.

the "crud" kinda comes to the top and not the clean and pristine oil you want in the pan.

also, I would go with a higher quality baffled catch can which doens't need any steel wool.

just me but I don't want anything breaking lose and sucking into the intake and the baffled solutions are better.

just look at the air breather box.

also, the little crappy filter in the cam cover, guess what falls apart and ends up everywhere.

I found some interesting garbage attached under the oil pick up screen when I just went though a total rebuild - broken up plastic filter from the cam cover and parts of ground down plastic from cam chain guides.

How many miles on that rebuild you mention?

There are two small locator pins (one each side) of each piston rod end attached to crankshaft (rod bearing). The two pins locate each half of the crankshaft piston rod (rod bearing). I found one of those pins in the oil pan one time and the engine had never been taken apart. It must have came that way from factory. ALL Rod bearings were in great shape including the one rod bearing associated with the piston/liner I was removing. That piston rod bearing had both pins installed.

I didn't find any locator pins in the oil pan when the motor was disassembled for the first time last year.
What we found this time, running a magnet through the crankshaft oil galley, were pig tail looking steel bits. These didn't look like shavings from offset grinding (what do I know-could be...). Could have been from original crankshaft manufacturing resulting from tapping to thread for plugs or could have been from regrind. Either way, made sure oil galley was cleaned out and plugs, both threaded and press fit, are installed properly.
Now I have 80 psi pressure when cold and 40-45 psi when warmed up at idle.
I certainly learned a few things having gone through this twice.

How many miles on the engine you rebuilt having the worn chain guide parts in the oil pan?

[secondchance]

How many miles on the engine you rebuilt having the worn chain guide parts in the oil pan?

Only about 10,000 from the last build. I think operating pressure from the chain tensioner is such that the chain guide wear occurs at the beginning. Once broken in, probably stops wearing further.

Are the pins you are talking about refers to parts of the bearing that are pressed out to fit into main bearing and rod bearing caps? If so, only way they would separate is if the pressure on the bearing was such that the bearing rotated resulting in pin shearing off.

Was just curious as you said "parts of ground down plastic from cam chain guides" leading me to believe the chain guides had or were failing not just wearing in.
I concur with your assessment that once the chain links wear the groves into the chain guides the rollers will be supported for a very long time with very little additional wear on the chain guide.

Yes...that be the pins and I concur with your assessment which leads me to believe somehow one got dropped in the oil pan during engine assembly. It was just a very unusual find.

[Karl]

Well life has been good I guess and I am on my 2nd ZR-1 and of course there is a catch can.

This one is installed low on the frame rail. It sits a smidgen higher than the header.

This one is off eBay and has a few of my minor personal modifications to it. Nothing too special.

One note if you install a oil catch can make absolutely sure the line coming from the MAP sensor is pointing downward. If not oil will puddle and cause a backfire at start up and a poorly running car.

This is the can I use off eBay.

Karl,

I have the exact same one (except its polished aluminum) and its installed in the front left of the car, where the AIR system was located. Do u have any steel wool in there, or are u simply using gravity to have oil drop out of suspension?

I am using a combination of steel wool tucked under home Depot aluminum gutter guard. I use the gutter guard to keep the steel wool packed in.

I also made the inlet line about 2 inches longer and it points to the catch can wall...if that makes any sense.

[Karl]

This is the gutter guard I use.

Ok, that looks like something I could do. My catchcan is attached to the frame rail by the horn assembly. Its tipped at about a 40* angle so the headlamp buckets can rotate freely. Have been using it for a number of years now, and the plenum still gets oil in it altho never as much as previously. As I said, I am using it as an air oil separator. Do u think that since I have no steel wool in there, that oil may still be getting sucked into plenum?

[Karl]

Odds are probably yes there is still oil getting past the catch can. It is just a hollow shell. And with all the air and turbulence the oil needs to be separated some how.

My '92 had the catch can mounted under the driver headlight but decided to move it low after doing some homework.

I will be at Marc's BBQ this upcoming weekend so you can see the car there and chat more about it.

[Karl]

See post #21 for the modified catch can inlet

http://zr1.net/forum/showthread.php?t=29346&page=3

[Ccmano]

Haibecks theory is that very little oil comes from the PCV system into the plenum. This is what he thinks is going on.

“I noticed that the inside of the plenum was always soaked with oil. In fact several drops of oil can usually be poured out of a typical LT5 plenum when it is removed from the engine for service. I tried to reduce the oil consumption by installing a two gallon accumulator tank with a coalescing filter on the vacuum line where the PCV tube connects to the plenum. The accumulator would collect only about 10% of the oil that the engine lost. I believe that this proves that the oil loss problem is not through the PCV system. If oil catch cans are installed on the crankcase vent tubes that connect to the air horn, they do not collect oil. I believe that the oil gets past the piston rings and moves up the intake air ports via reversion. My theory is that the rings loose control of the oil through some combination of poor cylinder bore geometry and piston ring flutter.”

I tend to agree. My catch can only picked up a couple ounces in the last 1000 miles and yet when I pulled the plenum to change injectors recently there was oil in the plenum.
