[T3] update on cross threaded plugs

[<veedub@apartment101.com>]

<x-charset iso-8859-1>As everyone may remember a few weeks ago I had a problem with a cross
threaded plug on my Notchback.  I thought the problem was fixed but all of a
sudden I noticed she started running funny upon acceleration and she doesn't
have the get up and go.  Also, I think I hear a very, very faint tapping on
the left.

I check the valves, none were tight, none were loose. all were .006, and the
plugs looked clean.

I ran a compression test wet and dry and here's what I found:

Cylinders 1,2,3 =3D 110-112# (consistent)
Cylinder 4 =3D 92# (this was the cross threaded cylinder)

I squirted some oil down the cylinder and the compression jumped to 110# on
cylinder 4.  So, I am guessing that I cracked a ring.  Would this be =
possible if my spark plug was cross threaded, and that cylinder was running
lean?  Or would this have been a previous problem waiting to happen?

I will take the engine out and get a better inspection tomorrow.  In the
meantime, I appreciate any thoughts you could send.

P.S.  Thanks for the tips earlier, Jim.=20
