Wow! Thanks for all the replies!
427Z06- I've considered that myself, the Auto-RX, as I have an unused bottle right here I've been itching to use. However, at the rate this thing leaks oil out the valve cover gaskets, I'm not really sure how effective it'd be. Of course, I have my dad's recollection of how much it leaked, which may not be all that accurate. It's pretty much sat for at least a year now, so I think I'll change the oil in it and check in with them every week at first to see how bad it's really leaking it. If they can go 500 miles without it burning off a couple of quarts, then I'll risk an Auto-RX run on it, it'd be interesting just for the sake of intersting at least.
Frank D- Nope, didn't overtighten the filter. I put it on just like every other filter I've put on, it hits the base, and I go a turn and a half. Incidentally, my Plymouth Acclaim had the same fate happen to me with, you guessed it, a Fram. I lucked out on that one though: I came out of class and was parked nose up on a slight incline. I got to see bunch of my brand new Mobil-1 Tri-Synthetic on the ground. Again, Thanks Fram! I guess I just personally have bad luck...
mcrn- I don't either...but like I described to
427Z06, the rate of seepage from the valve cover gaskets may make Auto-RX impossible to use here. We'll just have to see...
Gary Allan- Thanks for the opinions! It may very well be either of those conditions you described, however I'm not a mechanic so I cannot comment for sure. I know previous to my little low oil highway jaunt, the engine ran with no noises at all, very smooth (for a Ford 4.0L OHV V-6). However, after the incident, it now has like a cyclic (in period and duration) sort of tapping or knock or something like that. Tomorrow night hopefully the battery will be charged enough I can get a guage on what it sounds like again...it's been a year at least since I've heard it because we never run it.
dwendt44- Yep, it's RWD, however the engines in Aerostars are like buried
way back in the engine bay. My dad asked the local mechanic who we trust mostly how much it'd cost to fix it (because other than the smoking done at stoplights from the oil leaking out of the gaskets, it's a great runner), and the mechanic shot him a look and said something like, "Oils
lots cheaper. I don't think you want to know how much it'll take to fix it...I'd have to drop the engine just to get to the problem." Suffice to say, we've been going the add new oil route.
JohnBrowning- I don't think it's varnished lifters...whatever the low oil situation caused, it caused in about 5 hours/280 miles. Unless varnish can form that quickly, it's not varnish. MMO I'd be willing to try, do you know how long it takes to work?
ziggy- I'm not really up on the high mileage oil bit, you don't happen to have a short synopsis of what's good or a good link do ya? If not that's cool, I'll do some searching here too. Do the high milages have some better benefits for an engine like this? The 5W-40 diesel oils I'd be willing to try, like Shell Rotella T Synthetic 5W-40, however any of the true synthetics I wouldn't, as their just going to leak out and be expensive smoke coming from underneath the van.
hotrat- Interesting advice, and another vote for MMO. Looks like it may be going in this ride... You think a 10W-40 PCMO over a 10W-30 or 5W-40 HDEO would be a better choice?
KieferS- I've seen 15W-40 flow, albeit in Chicago cold winter, and it was
not flow inspiring. Unless I need to go up to a 15W-40 to stop the tapping - which I will if I have to - I'm not going that route.
Maybe an option for this thing, depending on how fast the seepage is, is to use like a 10W-30 HDEO and a quart of Redline in it for the esters (polarity) and the Moly. Or, something like SLOB or VSOT, cheap and carries high loads of anti-wear.
I guess at this point all options are open until I find out how bad the leakage really is.
Thanks again for all the opinions!
