Yeh, the bottom of the block makes for a handy storage place for dropped parts. Keep'em, you never know when they come in handy.

A clogged PVC system can create 'breathability' problems which can mess up idle speed and top end speed, along with blowing seals. Your engine runs on vacuum parameters, and the change in vacuum will make the computer think the engine is either running faster or slower than it really is.

Knock sensors do die, but many mechanics install new ones with the wrong orientation and that overloads the computer with false readings. So be careful when you put the new ones back in.

The crumbling wire harness covers can be corrected with large vacuum lines slit lengthwise and a few wraps of electrical tape.

Next month is my turn to open the bonnet and take a looksee, I do need to wait for the ice to melt on the garage floor.

Currently engaged in the SAS bypass.
