First thing I noticed was plastic/teflon pieces trapped in the pickup tube screen. Then I saw that one of the guides, driver's side chain, had come apart, where the pieces came from, but also the chain was flopping coming off the crank gear and the crank gear also drives the oil pump and that contributed to the oil pressure needle fluctuation. The pressure was good but the fluctuation was causing problems with the VVT solenoids and setting a correlation code, that I was chasing. It's all fixed now and running fine.</p></blockquote><p></p>
