Big Al XLT

The longest interval was just under 4,000 miles. Most of the rest were 1600 to 1800. One was 600 and still had 4% fuel.



Just about every drive I take is at least 25 miles. On a rare occasion I will drive the 2 mile trip to a local store.

Same issue summer and winter.

They need to look at the hpfp oring where it mounts. If it fails it will leak fuel directly into the head/engine. Its an easy one to do for a tech.

But since the OP states he had it replaced wouldn't that mean the oring was replaced?

FWIW, a catch can solved my fuel in oil issue. My oil level rose just like you mentioned. Pull the dipstick and it smelled strong of gas. Installed the CC and CSS at 4K after my first oil change. My oil level no longer rises and the oil smells like oil, no gas smell whatsoever. The stuff in the can reaks of fuel. If it's not the HPFP, depending on engine break-in, rings can seat poorly and allow more blowby. A properly operating CC can help extract fuel mixed with the blowby.

There are as many CC naysayers as believers. I've experienced the benefit and seen what gets caught. I also run one on my LLT V6 DI Camaro (solved the same fuel in oil issue, although it wasn't as bad as the EB) and LS2 (port injection, so no fuel in oil issue, but known for dumping a lot of oil in the intake). The stuff caught in the two DI engines is similar (more water in the EB since it's mounted out front) while the port injection is purely oil. IMO, any DI engine can benefit from running a CC.
