Jeremiah...I won't get into the badging wars, nor diesel or not wars...
I spent a ton to time reading up on diesel when all of my buddies with diesels
said it was the best...better than my 7.4L...even though I could keep up and
toast them when driven as a 'car'
Spent another ton of time on the famous thread here on the Bosch CP4. Learned a
few and contributed a few
Could see how the Bosch engineers added band-aid after band-aid till it is now
just BARELY making the cut...even then at any moment...it can blow up to spew
debris into the fuel system
Common sense and a good free association talent are both missing in a
large measure with both Bosch management and engineering
DCL is a wonderful coating in the RIGHT application...but...using one of the best
known non-stick coatings on a VERY HIGH PSI interface that then has a VERY, VERY
poor lubrication medium (diesel) is just asking for problems. Non-stick as in
asking the VERY POOR lube to have very high film strength to coat that best
non-stick material coating... Betcha the DCL coating is 'dry' most of the time.
Then that they had a 'floating' piston rod NOT connected to either the cam nor
the piston bottom. Think if an ICE's piston floating without a wrist pin and the
rod not connected to the crank shaft. Pure dump engineering. They should have
and still can, employ a 'caged desmodromic' setup on the cam side and capture
the piston to rod (IIRC...the piston might be captured to the rod, but it's been
a while)
I did not and still do not like the onerous SMOG measures and can only hope
that they will make a big discovery to bring back the MPG of old, along with
the power of diesel
My issue is the weakest link continues to be the Bosch system no matter which
vehicle badge
More so for long term owners and used buyers...ticking time bomb IMHO
