Clogged PCV tube
 

Took advantage of the nice weather to finally replace my PCV tubes and hoses
on my '95 GC Limited (143K miles). Just as I thought......99% clogged! I
took a deep breath and blew on the tube and could barely feel an airstream
coming through the other end - of course, a much weaker vacuum pressure
would be useless. Here's a pic:

The front intake tube had some sludge but not totally clogged like the rear
tube. It was the only crankcase ventilation I had, as evidenced by the
oil-stained air filter. I guess I will have to check these tubes more
often. I was noticing some engine power decrease at low rev and a few rough
idles over the harsh winter, but since I dont have a garage I played ostrich
and tried to ignore it until warmer temps would allow me to tinker and
explore.

The question I have now is - should I buy a bottle of oil dye and see if
there are any leaks caused by this PCV cloggage?

That won't cause an oil leak, just excess oil on your air filter.
No reason to use dye.

So the excessive crankcase pressures are just a myth? I've perused some
websites that seem to indicate long-standing PCV cloggage can cause massive
oil leaks anywhere it can find a way to escape. The only leakage I've seen
so far is around the outside of the oil dipstick tube.

All major gasolines use PCV cleaner additives, what are you
burning?
