M50 Valve lifter tick

If anyone has the sticky valve syndrome, which shows up as a medium pitch ticking at idle try using a detergent like marvel mystery oil. It worked wonders to remove the varnish build up.

My tick was there all the time. I left the oil in too long and varnish got built up around the lifters. I was seriously thinking about replacing the lifters and perform the pelican camshaft removal.

Anyway, no need now.
