HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

LS6 PCV setup...

Post  docwyte on Tue Nov 15, 2011 12:22 pm

So I'm about to do this as I use too much oil on the track. Apparently this is a known fault on the LS1 motors, Chevy fixed it on the LS6's. If you track your car I recommend you do this swap.

Found a nice DIY here: [You must be registered and logged in to see this link.]

I ordered the parts from [You must be registered and logged in to see this link.] They were extremely reasonable, $55 for the valley cover and $6 for the cap, which admittedly is a bit much. However the dealer wants $100+ for the valley cover, Summit Racing wanted $90 for it, so I'm ok with spending the cash on the cap.

Access on our cars is easier than on the F body, the motor sits more forward in the bay, so getting to the rear of the engine is pretty easy.

Hopefully I'll knock this out in the next week or two.

I did this on my car.

You will still need to run catch cans. You will still suck some oil from the LS6 valley pan, for mine it is 2 tablespoons or so for each 20 minutes of running.

I have a catch can already, so I should be good. How do you have yours plumbed?

I have two small cans set up.

1. Out from the LS6 valley pan to the can then to the intake located just above the LS6 valley pan outlet.
2. I tied in all the ports from the valve covers, these go to a can and then to the top of the throttle body.

Sorry, don't have a pic handy.

Where's the pvc valve mounted in relation to the cans?

Just one more part to fail and it is not really needed.

If your running the updated LS6 valley pan you dont need a PCV valve, it uses a metered hole instead.

I installed this PCV directly to the rear driver's side head and have not had any more oil blow-by into the intake.

I plugged the 2 passenger valve cover ports and routed the rear driver's head port (with pcv-1009) to the throttle body and have had zero issues....

Uh, so, this is why I was down almost 2 quarts after about 1500 miles after both of my last 2 oil changes?!

I was blaming it on operator error (me).

Man, is that a load off my mind...

I am running the LS6 PCV valley cover and my oil consumption is nothing. The oil level has been the same since I first cranked it over.

I also have an extra one (new in box) if someone is looking for it.

Most likely acorad. Apparently this is a wide spread problem with the LS1's, I have the same issue with losing oil. That's why I'm doing this...

I ran for 90+ minutes at the track today, I think I collected less than 100ml of oil in my catch can.

Nice! I'm looking forward to getting this on the car. I'm slowly checking off the off season project list on it. After this is basically just normal maintenance like fluid flushes and new front brake rotors.

Misc needed parts and tools bought yesterday, LS6 valley cover supposed to arrive tomorrow. I have military duty this weekend, but will hopefully get enough free time to install it this weekend.

After that the car gets an oil change, new front brake rotors, brake fluid flush, a muffler/resonator installed to quiet it down and an alignment and corner weigh.

Got a nice day today and my buddy and I tackled this project. It's not hard, but it is time consuming. It took about 6 hours to get it done, although an hour of that was spent waiting for some rtv to dry.

Everything is easily accessible, I've got a write up with pictures coming that I'll post...

Actually not that many beers. Took two trips to the auto parts store, had to wait an hour for the rtv to dry, took about 30 minutes to cut the block down, then I had to bend this coolant hose dealie around the LS6 PCV barb.

Time just kinda flew by...

What do you guys think of this?

(On page 5 of this thread: [You must be registered and logged in to see this link.]

"The simpleist way that I have found to eliminate the oil consumption problem is this:

Mount the PCV valve vertically in a line running from the back of the passenger side valve cover fitting to the driver's side valve cover fitting. Basically, you run a hose from the fitting on the back of the passenger side valve cover to the 90 degree (plastic) fitting on the driver's side valve cover. Cut the hose & install a "T" fitting. In the vertical leg of the "T", is a 1.5" or 2" long 3/8" hose poining upward. The PCV sleeve mounts over this piece of hose & clamped to the 3/8" hose. The PCV is mounted fat side down into the sleeve & clamped (if you have no sleeve, use a 1" or so piece of hose with an ID large enough for the PCV base to fit into). Now run a hose from the top of the PCV valve to the throttle body & secure the PCV against the firewall ensuring that it is vertical & you are done. The car remains plumbed as it was intended by GM & no more oil consumption. No catch can, breather cap, plugged holes, or small orificed PCV valves. Cost is for a "T" connector, some hose clamps, & a little bit of 3/8" vacuum hose.

If the short line from the passenger side valve cover, this is the second line toward the front of the engine I am describing & not the line discussed above, continues to allow oil into the intake, a small fuel filter can be installed in that line. Mine does not."
