TR2 stuck rings update - appears that AC Delco product works
sort out the TR2 and was reading with interest about
ways to improve
compression on an engine that's been sitting for a
squirting marvel mystery oil or engine oil - depending on
what I had open in
to the cylinders every 2 years or so and rotated
the engine by hand to make
sure things were coated.
My Triumph club (TCOC) and I started it last year
and it ran but
poorly- we did a compression test and got: Compression in
-- pre test - 130, 130, 110, 80.
Fast forward to today - I put
more marvel mystery oil in it over the
past year - and got essentially the
same compression readings as last
year. I tried some ATF and got some
improvement 140, 140, 120, 90.
There might have been some residual oil as the
140's seem quite high.
I tried kerosene, pb baslter; areokroil and wasn't
improvement. That was all cleared out of the oil when I pulled the
oil pan last month (but maybe that's why the inside of the engine
My friend in the Triumph club, Paul, said he'd tried a product
ACDelco X66-P Carburetor Tune-up Conditioner on a T250 that had sat a
and it really did the trick.Wasn't sure if they even sold it
of us has any financial interest here.
He called me the other day and said he
dropped by a garage and they
gave him a dusty can. It had a 1995 sticker on
it but was full. I
took compression readings again (cold) and got 135, 130,
110, 90 . I
put 2.5 oz in each cylinder and let it soak a full day. I figured
cylinders with the good compression likely had gunk that could benefit
from a cleaning, too. Paul said he waited 3 days but I'm impatient.
I stuck a
screwdriver in each plug hole and there was no liquid - so
'26 hrs later, I
put the plugs back in and gave it a spin - I probably
should have changed the
oil but didn't. I ran it up to temperature
and did some 3000 rpm rev's from
time to time to make sure I was
burning what was left over.
After about 30
mins I went out and made another test - warm - 135,
130, 120, 130. I decided
that maybe I should check the valve
adjustment and while doing so realized I
was still running a hand
ground rocker arm adjustment screw I'd made years
ago. I pulled down
the rocker arm assembly and replaced the parts from a unit
I bought on
Ebay a few years ago. -- From my old notes I was setting at .010
intake and exhaust -- this time I set intake at .011 and exhaust at
Another compression test - went 135 130 125 130. my manual
says they should
average out at 120 - so I think I'm doing well for an
engine that has not had
any major work for at least 40 years.
I made my first run out of the
neighborhood today - A run to the post
office, grocery store and wine store.
It ran well and idles much
more smoothly. Since I had balanced the carbs with
compression - looks like I'm due to repeat those steps as well. Oil
pressure at speed is 70 psi - is that too high? - at idle - 45 psi.
