Old dog, new tricks
...until I replaced a few o-rings!
I've been chasing leaks on the old 7.3 Powerstroke for about 2 years. After a considerable amount of research and advice, I finally chased the engine oil leak to the HPOP fittings. Thanks to the fine folks at dieselorings.com, I now have a leak-free truck! But wait...that's just the beginning...The damned old thing RUNS better than it has since I've owned it (about 3-1/2 years)! The idle is much smoother, the acceleration is quicker, the engine just SOUNDS better. Healthier. Definitely a palpable improvement in driveability!
All I can surmise is that the oil leak was causing reduced oil pressure to the injectors on at least one cylinder bank, and that increasing the pressure, by eliminating the leak, brought the old beast back up to *****. That's just a guess...I'm not a diesel mechanic or an engineer! Suffice it to say, though, that I'm one happy camper (yes, I do drag a 30-foot travel trailer around with it).
One of the o-rings (can't remember which) looked more like a hardened piece of plastic or cardboard upon removal. Of course, I'll assume that it was the one causing the majority of the problem. No matter, it's a done deal now. Pain in the butt, but DONE!!!
Cheers...
