How long will my HF motor last? I am worried

Oh yea, it has to be added every oil change or it gets washed away with the fresh oil!

crx hf's are commen for engine swaps, it's sad but it's true, the positive side affect of this is a surplus of good used engines, I was quoted about $300 to swap out engines in my CRX that has the same problem, it's been burning a 2 quarts of oil per 350 miles due to having been abused in it's past life, combined with the engine only being designed with 2 pistion rings insted of 3, I ended up buying an engine, and good transmition, $40 for the two, from a guy who was doing an engine swap, but due to a lack of time and ambition, and that my brother is now useing the car, it's still running on the old oil burning engine, I've owned the car for about 40,000 miles now, done a 7,000 mile road trip where I went thru a case and a half of oil, and it's still a solid car, fixing it will make it use both less oil, and less gas, and increase it's value, so take that in to acount, but as a short term fix, thicker oil, and aditives all help.

Well on the positive side your exhaust system is well lubed and will last a long time.

Have you checked your PCV valve operation? I've seen a plugged PCV valve on an old chevy cause oil to blow back up the PCV air inlet line getting oil into the combustion air. Its easy enough to check.

You could try some of that high millage oil in a bit heaver weight than you normally use and it should be good for a long time.

The HF motor has the same number of piston rings as every other D-series motor. That's 4, technically speaking... Two compression rings and two oil control rings.

Hi guys thanks for all of the great advise. I replaced the pcv valve about 1000 miles ago. It was clogged and dirty. I added a treatment of restore today. Hopefully this will help. I also bought a gallon of oil from Napa and will just keep on adding oil like some of you have said.
