Last night I dropped the pan.
And I found the source of the noise.
The crank is badly buggered at the #4 rod journal.
Oh sh*t! Oh sh*t! Oh sh*t!
And the rod bearings are already 20 over.
Perhaps this engine has more than the indicated 86K miles.
I haven't pulled the head and pistons but I have a feeling the #4
cylinder may be damaged too.
I'm looking at some major work here.
What's my next step? Pull it out and see if the crank can be reground?
Or what? I didn't sleep very well last night.
