Gen 3 Motor Issues - Piston Soak - Blowby Pressure

Yup:

e85 cleaning as posted above, cleaned intake ports, intake valves, fuel injector tips, poured some e85 through the lower pcv connection to clean out the built in oil trap, and did the open air crankcase ventilation conversion with the open air breather can and 5/8" breather lines ran as short as possible, and swapped to high mileage full synthetic 0w-20 motor oil changed every 5k.

I would say the breather can probably didn't do much, so it may or may not be useful to follow that one.

But the e85 cleaning as i did and swapping to high mileage full syn changes every 5k are huge. Extra cost on these is like $5 for the cleaning and maybe $2 every oil change.

 

Per an old post from me:

"I was gonna add that I did a piston soak at 203k. Made the car like brand new again. Basically as good as most average new cars can be.
Went from:
Consuming 1/2 quart: every 400 miles on the interstate. Maintaining 75 mph through 15% grades is tough.
Around town 1 quart: every 4000 miles trying to keep the car at 2100 rpm for pulse n glide like driving.
Averaged (55% city, 45% hwy): A quart every 2500 miles if it was a busy tank on interstate 1500 miles.

After piston soak at all rpms and all conditions car now consumes a quart every 10,500-11,000 miles. But oil is changed at around 5000 miles so it ends up being around a little bit less than 1/2 quart every oil change. Now I can strap kayaks to the roof, do interstate trips, and tow the occasional trailer with a fridge or jet ski no problem.
Also, installed an oil catch can and swapped to high mileage motor oil to combat weepy oil seals.

Car runs like brand new now."
