Once again I call on the combined wisdom of Team.Net
A friend brought his 1994 Nissan Maxima V/6, with 120,000 miles to my
garage. #2 cylinder not firing and it had a slight knock that sounded like
it was coming from the distributor.
Everything in the distributor was OK. The Cap, rotor and plug wires are
less than 50,000 miles old. There was no play in the rotor shaft.
I ran a compression check and #2 was very high in comparison to the others.
We put a new plug in #2 and fired it up. The engine now sounded like someone
was wacking around inside the head with a ball peen hammer. As you brought
up the revs the sound fluttered and went away.
A pro mechanic friend took off the valve covers and checked for bad lifters,
broken springs, bent valves etc. He found nothing. He also did a compression
check and his readings showed #2 very low in comparison to the other
cylinders.
Before we take the heads off, we are going to try one of those top end
engine cleaner kits that go in place of the fuel line, in the hope that it
is carbon in the cylinders. Still, this is weird. Has anyone on Team.Net
experienced anything like this with this engine? Inquiring minds want to
know.
Thanks in advance guys.
