[Vwdiesel] Ring Break-In and Oil Consumption

[Rudy Petersen]

I use a fine Jewelers Rouge heated and mixed with a heavy oil.  Remove head
and paint a swipe around cylinder low in the bore.  Works good in small
Diesels to dry them up.  We use it in Sprint Car engines to help seat Chrome
Rings.

Its a funny thing. Loren mentioned it the other day & I find it to be true
also: engines that are babied use oil. German engines any ways. Same thing
was true at BMW dealer. Beat the piss out of those cars & they loved it.
As for your 1.6 N/A, it may be too late, but worth a try. Use fossil oil,
like 15w40 & go on a long trip. Lots of high speed & long mountain grades.
Keep motor singing. If you can get a couple thousand miles in like this,
your motor may be OK.
As a last resort - this old guy I knew (even older than me - lol) would
build Bultaco motors for racing bikes. Built motor real tight, closer than
factory clearance specs. Then start it up & chuck Bon-Ami into intake. Sink
scouring powder. Polished everything, seated rings. Worked amazingly well,
but I've nevr tried it myself.
Try long trip first. Good luck.

As you guys may remember, last summer, after lots of fussing around and help
from this list, I completed installing my rebuilt 1.6 liter NA engine into
my Rabbit.

The outfit that did the rebuild wanted me to use regular lube oil for the
break in.  I followed this recommendation rather then to use a non-detergent
oil that does not contain friction reducers.

The engine got very good mileage when I drove it up to Hagar's place
in BC.   Now it has 5000 miles on it.  By checking the oil level with
the dipstick, I estimate that the engine is using roughly one quart of oil
per 1000 miles, which is not much better then it was at zero miles.  This
causes me to think that I have a serious problem with the rings not seating.
This is my first 'new' engine that required breaking in, so I am relatively
ignorant and there is lots of stuff that I don't understand about the
break-in process.

So, what I can expect to happen over time?  Will the oil consumption slowly
improve as the rings wear, or will it never get much better?

What are the consequences of having high oil consumption?  Will this mean
more deposits in the cylinders or more crap getting past the rings and
effecting the proper operation of the rings?

What can a guy do short of honing the cylinders and starting over?  Is there
any point now in running non-detergent oil?

Lots of questions.
