Any opinions, thoughts, comments, tips, criticism, guesses are greatly appreciated.
Will follow up on result.
Carb turbo 2.3 engine recently suddenly burning way too much oil, very visible smoke on accel.
Dipstick level checks after 50 miles since June confirm it is an oil problem.
Have read up and refreshed knowledge on diagnosis and repair. In this case, more is better.
Turbocharger and its oil feed have been disabled and eliminated as source of oil problem.
Idle steady idle vac steady 18-20.
Engine power normal, no noises. Compression 180-190 all cyl. Plugs not wet.
Coolant normal temp and level.
Cannot detect any oil in intake, pcv, vac lines.
No leaks other than usual seeping from gaskets. No drips on ground.
Engine otherwise appears to be sound, vg fuel econ and power even after 150k, rebuild by me. Not raced.
Stock config engine, total rebuild in 2000 with durability, material updates, daily driving shared with Ranger.
At this point, plan is to change out one valve stem seal in car successfully and DRIVE it.
.
Will be trusting air to hold valve up. Rope was considered. Compressor holds air for weeks. Max 125#, kicks on at 95#.
Will have breaker bar and socket on crank to hold cam timing, crank at #3 TDC, verify with dist rotor position.
Have correct air hold, valve spring tool, magnets, towels, rags. Aim for total control of and not losing the valve keepers.
Have the stem cover in kit for valve stem tip and will lube it with drops of oil. Will seat seal per Ford shop manual.
Never did this particular task before on car. Will be replacing with same type from 70373 Felpro set.
Overcoming paranoia, anxiety, on dropping the valve is a challenge. Will use thick rubber band on stem.
Goal is to avoid much more work pulling head or even replacing engine.
Overthinking the situation can eat ya up. Taking time not to guess on anything, overlook details, overall procedure.
Have repainted valve cover and cleaned the beautiful no leak Felpro blue PermaDry gasket to keep calm.
Am working outside. Perfect weather here. Going for it.
Have i found something?
Is #3 exhaust, 2.3 engine.
Looks like piece of valve stem seal rubber missing, exposing valve stem under bottom seal ret ring.
All other seals look fine and seated far as i can see with digital inspection snake camera, inspection mirror, magnifying glass.
