Need Help Find Timing Marks On 1986 Olds Delta 88 ?
Engine Size 3.8
requested timing marks 86 88 3.8L
ignition timing or valve timing?
The picture in the previous post was the camshaft to crank shaft timing marks
There may be no ignition timing marks - I think the 1986 3.8's used either DIS or C3I ignition systems thus had no distributors and no static ignition timing adjustments
