I just had a great weekend at Summit Point, perfect weather, four days =
and lots of track time, some quick laps and good racing. =20
After my last session, I noticed some dripping oil as I put the car in =
the trailer.
Got it home to find a half full catch can (1 pint?), and evidence of oil =
blowing out of the valve cover cap vent hole.
Tonight I ran a compression test and leakdown test. Cold engine =
results:
1 - 200 and 2%
2- 180 and 6%
3 - 180 and 9%
4 - 195 and 0%
5 - 190 and 0%
6 - 185 and 0%
Note - I suspect my longacre leakdown gauge may not be reading quite =
right, as when i have the air side set to 100, the leakdown % on the =
last three is slightly below zero. So, perhaps the leakdown on the =
first three is higher.=20
There was no excess oil until the last session. Oil pressure is about =
50 hot at idle and 65 - 75 at speed, depending on RPM.
EGT readings remained in the 1200 - 1250 range across three monitored =
cylinders at top speed
What do i have - failing rings? =20
Any diagnosis or tests you recommend before I start pulling the thing =
apart would be appreciated.
Triumphs racing - I=E2=80=99m sure I=E2=80=99m missing a few but this is =
who I remember.
TR3 - John Hasty, Henry Frye, John Styduhar
GT6 - me, Paul King, Jason Sukey, Jay De Pol until his diff case broke
Spitfire - Russ Moore, Marty Sukey, Jeff Govert, Kent Bain, others=20
Tr4 - Mark Wheatley, Allen Goode, I=E2=80=99m missing at least another =
one
