I have forwarded a message that I posted regarding my friend who switched his
318 Dakota to synthetic oil before breaking it in (27 miles) and who ended up
with rings that never seated. Just thought some people would enjoy the tale
of the rebuild!

Related note on my friends 1997.
When we tore down his 5.2 for a rering at 77,000 miles or so, the engine was
spotless. His cylinders STILL had cross hatch down the entire length of the
bore, measuring the bore indicated a .0001 wear yes that is 1 ten thousandth
of an inch. Bearing clearances were still a little tight according to the
FSM so we left it alone, there was not one measurement on the reciprocating
assembely that was not 100% in spec for a NEW engine. We reused the
bearings. We did install ARP rod bolts and reconditioned the rods. We
installed a 2x roller timing chain, and a MP R/T Cam. His heads I ported
using the MP templates and installed Hughes Engines 1.6 roller rockers.
Valve springs were replaced with the suggested R/T springs seals were new
felpro valve stem seals. Heads were milled .010. Then the whole thing was
reassembeled with felpro gaskets. His truck has a K&N Gen II, MP computer,
headders and exhaust. We wish we would have installed the M-1 intake and
4bbl throttle body at the same time, but we didn't. He also installed a
custom ceramic clutch at the time of the re ring. The rings used were
Hastings stock replacement rings. He now has 157,000 miles on the engine and
truck which puts roughly 80,000 miles on the rebuild I did, still uses NO
oil, (well it did the first 3-5000 miles until the rings seated, but this was
using regular oil) and is VERY powerful. Clutch was made at Ted's Clutch in
Redford Michigan. Just thought I'd share my story with everyone, I'm proud
of this engine that I built :o) mostly because it has run a LONG time!

PS the truck is a 1997 Regular Cab Short box 2wd Dakota with the 5 speed.
