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 …

Oil fouled plugs - Catch Can needed?

Post  acorad on Tue Oct 16, 2012 6:07 pm

After sitting for a month or so I started my car and it had a bad miss. Code P0307, cylinder #7. The coil and plug wire was fine, so I pulled the (pita!) #7 plug and it was coated in a thick mess of oil. Checked #1 as well as it is easy to get to, and it's also pretty oily.

I read that some people have added "catch cans" to their engines, would that stop this oil fouling?

Catch cans will definitely help, but i think the best solution is to switch to an LS6 PCV. I don't have the information handy any more as i did mine a while ago, but IIRC the parts came in under $100.

I might be crazy but i thought i might have done a writeup on it here...if not, i remember reading someone else's writeup at one of the camaro boards, you'll just have to google it. Just make sure you get the latest of the PCV setups, i think it was all from an '04 Corvette.

Oil problem

Post  fliermike45 on Tue Oct 16, 2012 7:15 pm

Contact xschop, he has a method of replumbing the PCV placing it at the rear of the engine. I followed his advice and have no problems with oil reaching the TB and Intake.

There is a commercial fix that puts a catch can in the line to the forward PCV.

Here is the link: [You must be registered and logged in to see this link.]

The LS6 valley cover has a built in air/oil separator that helps, but if you are racing or have more extreme circumstances you may also need a catch can or some other setup.
LS oil consumption issues weren't really fixed until the LS3 design was released. And still, its not perfect.

I installed a catch can from the beginning and have not had any problems.

You can see it bottom left

Was getting a miss and pulled the DS plugs and the #7 was oil fouled again, the rest were clean white-grey.

Do you think this is due to a bad valve seal?

The tell tale sign of bad valve seals is excessive smoking on start up? I know as I am often fogging for mosquitos!

I replaced all my valve seals about 2 tanks of gas ago, I have not had time to pull the plugs to see what effect that had on combustion yet.

Or you could be smoking on deceleration like me. Figure it's the rings and I'll rering and rebearing the motor this off season.
