I just changed some seals and timing components on my 1990 240sx.
started right up except for the fact that it wasn't running on all four, so i swapped plug wires 1 and 4 and it runs on all 4 now, (which is strange because i never took the wires off the cap)
and so it's running bad, like laggy, not powerful like it did before,
and now there's like a metal on metal sound like a knock or a tick, like the head is being starved of oil,

anyone else had this problem before?
