Oil catch-can
After reviewing the many pictures of engines that have been posted on CF for a verity of issues by members over the past 7 months, I have not noticed any oil catch-can installed. Since I will not do any mods to the base engine and my aggressive driving days are gone, I am wondering whether an oil catch can is necessary. I would appreciate any thoughts from those that have them and those that do not.

I recently installed an elite engineering catch can. I am driving my car in an HPDE event in a few months, so I wanted the protection. From what I read... If you are not using wide open throttle, I don't think you will get much benefit... maybe a little less deposit on the exhaust tips over time?

I have an Elite Engineering catch can installed on my stock '03. I do not use the car for any track events nor do I drive aggressively out on the road, but the catch can does work in keeping oil from entering the intake manifold. I empty the catch can every so often and it does have oil in it. To me, it was worth the expense.

The oil in the catch can is after a 200 mile trip with some spirited driving (entering interstate passing slower cars on 2 lane roads). It's only about a teaspoon, but it didn't get into my intake. I like the EE catch can, easy to install and empty.

Quite frankly you will be surprised with the amount of oil you will gather with the catch can, whether you drive hard or not. The catch can really should have been a stock item.

I recently purchased an Elite from a forum member basically because the price was too good to pass up. I installed it and went for a drive to Tombstone from Phoenix this past Saturday. 80MPH on the interstate, six speed, 1.600 RPM. 16,000 miles on the car. 400 mile round trip. Enough oil to cover the bottom of the catch can 1/16". Might not sound like much but multiply that by ? over the course of time going into the intake. Well worth the investment in my non humble IRISH opinion.

I, also, have found about 1/2 inch of oil in my Elite catch can. I drove about 3000 miles before checking it. I do wind my car out once in a while, but nothing too wild. My car is a 2001 6 speed with 39000 miles. The catch can seems to be doing its job and well worth the money.

Yes. Causing build-up on the valves. With a port fuel injected engine, as long as you are using a top-tier fuel, it's not an issue. It's an issue for DI engines. You also need to be careful because if the hoses aren't fit perfectly, you're going to run lean at WOT because unmetered air will get in and cause issues, and this condition won't be as noticeable when not running at WOT. Only real way to tell is to use a datalogger and check air/fuel ratios throughout the range before and after installation. A/F should hang around 14

. Especially if OP is running 91. Most ive seen is mid upper 12's. LOW 13's depending on timing. I wouldn't dare go 14's on pump gas.

So, I have a c7 Stingray with Z51 pkg and don't race or track and only once in a while really get on it, and if it matters use 76 Gas or Costco, why cause Costco has 5 times the min required and 76 has 2 1/2 times the min required cleaning additives . Whats your advise to my scenerio?
