Oil Leak (and other) Opinions Requested
Written by unlikelylogi... on 7/31/2009 at 02:40 pm

Yes, camshaft plug leaks can make quite a mess. It doesn't take much oil to
attract a lot of dirt and with all of the Tupperware you don't tend to notice a
problem until it drips.

Ideally you would clean the engine and then run it to determine where the
leak(s) start. In its current state the wettest vertical areas might be a clue.
The wettest horizontal areas are just where oil has pooled.

I replaced the camshaft plugs by pulling the head covers. It really isn't that
bad once you've dug that far into the matryoshkas. If you want to, um, screw it
then you'll want to bevel the edge of the new plugs just enough to get them
started into the heads. It's easier than trying to bevel the heads, less likely
to introduce metal shavings into the engine, and doesn't provide a larger
working area for oil pressure pushing the plugs out.

Other alternatives that don't require a hammer:

a. Expanding rubber plugs.

2. Epoxy or silicone artfully applied about the offending area(s).

iii. Earmuffs. Just pop a pair across each head. They'll absorb the oil.

Other maintenance:

- General cleaning.

- Check all electrical connectors for corrosion and apply dielectric grease.
Ensure grounds are clean and tight. It wouldn't hurt to perform the stator
tests while you're at it. Murphy says you'll get it all back together and then
... .

- Remove the coolant overflow tank and clean it. (Some dish soap, a handful of
6-32 nuts, a little water and vigorous agitation.) Then highlight the low and
high level lines with a permanent marker before replacing the tank.

- Replace the sub-air cleaner filter. Near ref (8) at:

- Check the auto fuel valve for leaks. Ref (5)/(12) at:

- Check the water pump weep hole for signs of leakage.

- Electrical farkles, e.g. adding relays to the headlight circuit, adding a
voltmeter, built-in garage door opener, low-tone horn, ... .
