I like the red one but you might need three arms.

I wonder if it was conventional oil and not synthetic?

For at least the first three years, our oil was spec'd as a blend and then they went to full synthetic. The dealerships "should" be using full synthetic to stay in the good graces of GM.

Im passing on the red one, they wouldn't be delivered till December. But they are copies of Texas Speeds. They are out of stock on their site. And yeah I just thought of the three arm thing that wouldn't work.

A little cheaper--View attachment 262190

This one for all ls or just ls1 style? I need either one of each or a combo.

Synthetic. Same oil used in my wife's equinox that requires the dexos oil.

I was just curious because the head and valve cover looks kinda dark/carbon caked compared to mine.

Here is mine with 260k miles for comparison and I run 13k-15k mile OCIs with Mobil 1 extended performance oil...

This was my original valve cover on the bottom and the Updated valve cover on the top...

Improved Rocker Cover - 12642655

Stock springs or LS6 springs should be fine. Glad it wasn't something inside the motor!

Summit doesn’t get any of my money anymore since I have to pay taxes with them. Even with the crappy pro discount. It does not pay to shop with them anymore.

I have only had it for a year and half. Who knows what the owners before me did.
