A bug engine I bought from NWCR lasted only 22,000 miles. 
Jerry replaced it for free and I've been a loyal customer ever since (30 years).I would put the blame on Northwesty before NWCR. 
You know what I mean.

​RE: NW Connecting Rod Rebuilds
Jerry does a 2.2 and a 2.3L in addition to stock 2.1L rebuilds.  Although
NWCR has a stellar reputation a close friend is have to replace her 2.1L
NWCR rebuild at just 50k miles, serious problems with it.  Installed by
Northwesty just a couple of years ago.  Zero compression on #1 and sucking
a quart of oil per tank of gas.  So Jerry's engines are not bullet proof.
And her situation is disappointing.  She has had a lot of running problems
in the last couple of years and Northwesty was never able to get that
engine in tune so don't know if the problem is the initial rebuild or that
the whole system was not set up right.  And about three years ago another
friend had NWCR go through her GoWesty 2.2L and when it was back in zero
compression on #3!  Jerry made it right but disappointing with their
reputation for good work.  Even my 2.3L had to be pulled after install to
correct a leaking seal.  Jerry stood by that and reimbursed my shop for
that extra work.
