Re: [MBZ] do I have bent rods?

[Kaleb C. Striplin]

One other thing I noticed looking down into the intake ports the top of 
the valves and the valve stems have quite a bit of carbon and junk in 
them.  Engine just seems like it runs too go to have the bent rod 
problem, no noise, no nothing really, just runs great.

Kaleb,
I do not have direct experience with this engine, but I can say that from the 
years of diesel experience I have (and gas, for that matter as well,) that the 
numbers you posted are all within 10% of each other, meaning that more likely 
than not there is no rod, piston or bottom end problem.  For that matter, I'm 
willing to bet you just have a leaky head gasket between a pair of the 
cylinders and coolant is seeping into one of them.

Might only happen when it's cold, possibly.

I don't think there is anything significant going on here in my opinion.  
You'll get the full story when the head is pulled, but I still wouldn't expect 
a major failure IMHO.

Quick backstory for those who might
have forgotten.  92 300SD, been using oil for a while,
no big smoke but you can smell it from time to time. 
Started using cooling maybe 6 months or more ago.  Been
getting worse to the point it uses about as much coolant or
more than oil.  Probably have to top it off once every
couple of weeks.  About the same with the oil. 
Anyway, Top radiator hose does not seem to get real hard
like some of them do, as was discussed before.  There
is also quite a bit of oil seeping out from somewhere near
the front passenger side, above the alternator area. 
Hard to tell where its coming from.  So today, I pulled
the manifold to do compression check.  Seems like some
oil in the #1, #2, and slight bit toward #3 area of drivers
side head.  Here are the numbers

#1 410
#2 430
#3 420
#4 450
#5 440
#6 415

Also, the number 1 glow plug had a little bit of a white
crust on the tip (see pic)  maybe its burned
coolant?  So, I am probably going to have to pul the
head.  First of all, would a compression check even
turn up bent rods?  If so, can you tell anything from
my numbers?  #1 and #6 are the lowest, but dont seem
real low to me, still seems like good numbers.
