On a side note, Toyota did have a sludging issue with its engines due
to restricted cooling system passages on these cars, and so did many other
models from this time frame. The use of restricted cooling system passages
was in response to meet stringent EPA tailpipe emissions standards.
Restricted cooling system passages increased engine-operating temperatures
and resulted in engine oil sludging. Toyota extended the warranty on these
engines.

So keep a watchful eye on the engine oil. If you observe excessive oil
consumption, then contact your dealer. They will replace the engine under
the extended warranty action from Toyota. I wish you success.

Dear    Tom,

Q I own a ‘98 Honda Accord V-6. Every time I get the oil changed, I’m

told that an oversized drain plug is needed (and that’s okay, because it’s
relatively inexpensive). However, I’m also told that a new oil pan would be a
good idea, and they are really expensive (about $300 to $400)! Seems to me
that there ought to be an easier fix than a new oil pan. Got any ideas?

Samantha,

A The reason for the oversized drain plug is because the OEM threads in

your oil pan have been stripped. This happened as a result of someone cross
threading the drain plug back into the pan and forcing it against the resistance
of the threads. Oh well, that’s water over the dam; however, I suggest you go
to a different place for oil changes. There is no way around this problem
except to replace the oil pan or use an oversized self-tapping drain plug. If a
good quality plug is used, this is an acceptable solution to the problem. Best
to you.

Tom
