This is my second or part II post.
About a week ago, as I was running tests on the engine to
determine the cause for the smoking issue, as I was starting
the engine I heard a pop and then the engine ran normally.
Yesterday, in anticipation of today’s disassembly, I started
the car, heard a thump and then the engine ran normally
As you look at the pictures on my website:
You have got to ask yousrself, am I smoking a whacky weed or
what? I can assure you that I am not. After seeing the
damage, I too find it hard to believe the car was even running.
I have read about exploding distrubutor caps caused by a
buildup of oils in the vacuum line leading to the AAV tube.
I have inspected the line and it is clear.
Now for some head scratching.
As you can see, the ‘‘T’’ from the AAV is melted. Thus would
cause no vaccum to be extracted from the distrubutor cap.
Why did it melt? I dont’t remember it getting caught
This might cause other problems, but not an explosion.
Now for the kicker.
When I wrote my post last week, before I began my
investigation about the smoking issue, I noticed I had a
major fuel leak on the #2A injector. I guess the new hose
had not sealed properly, or maybe I had cut it too short.
Anyway, I had seen the leak before and it went away, but
this time it was a major problem. I cut a new hose about
1/8’’ longer and replaced the hose. The leak went went away
I started the car, heard a pop. Investigated, saw nothing,
and started the car again. The car ran smoothly after warm up.
So unless anyone says different, here is what I think happened.
The accumulated gas pooled around the distributor. The pop
I heard came from within the cap as the fumes ignited. I did
not see anything, but there might have been a fire inside
the cap, which went out after the fuel was consumed.
The distributor cap was destroyed, but I could not see it at
I believe the ‘‘T’’ fitting had nothing to do with the
destruction, and as stated I think I would have seen other
problems. I also think the ‘‘T’’ melted as the flames were
being sucked back into the engine.
Why the car even ran is beyond me. I guess the plug wires
were holding the cap remains just right.
