I have lots of blowby, like you explained and the truck still runs great, Ive put 20K miles on it since I bought it and never had any power issues. I drove it 1100 miles a day for four days a month ago and it performed without a hitch, even towed some cars around in there on full metal trailer like there was nothing behind the truck.

I dont think blowby is all that much of an issue, even though it does seem concerning. And maybe it is not just blowby, perhaps its just because of your good pressure causing oil fumes. I too have high pressure. The first OPS I had showed about 45psi constant but when I changed it I now show 60-70psi most of the time.

Well, I think the blowby is typically either:

1) Oil deposit build-up
2) Worn out rings.

It's a pretty good bet that it is #1. Why don't you try the AutoRX stuff? My understanding is that it is a oil-miscible slow-acting solvent. You mix it in with regular oil change, run it for 3000 miles, repeat, then change over to normal oil. It costs a few bucks, but if it is #1, it should dissolve all the build-up and voila - all better!

I'd say it's worth the less than $100 gamble.

That's what I would do.

Missy's idea is essentially the same- the ATF has a very high detergent/solvent ability, and could help to remove oil buildup, varnish, etc. However, I like the AutoRX concept - it acts slowly, over a period of weeks, instead of harshly over a few days.

I have NOT tried the AutoRX product, but the approach makes sense to me.

Good luck!

My only issue with motor fulshs is sometimes it's better to leave sleeping dogs lie...No tellin what ya might loosen up..... Wanted to work on the fuel leak but I got started welding the floors in my big rig and now I'm commited(and should be !!)

 

[Acesneights1]

I should add that if I cut the 94 up, the 4L80e would also eventually go in the CUCV. It "seems" to be in good order although while out would probably freshen it up.

Couldn't agree more Kenny. I've seen that happen before with bad results...
Dump the 1/2 ton! or keep it for parts.
BTW, I voted for you to get a straight jacket...or whatever that choice was...):h

meds, not ready for jacket yet...

The perfect burb slipped through your hands, and there must be another like it somewhere. You got the 6.5 for a good reason, their easy enough to work on, and you know how to get it running if it does die on you. Not sure its the same story on the more expensive trucks.

Need to find an immaculate cab/interior and devote yourself to it, even if it means putting in a fresh engine. These trucks are cheap, find the one you like.

I agree. However, this is not a traditional motor flush. With a traditional motor flush (like Rislone or Sea Foam), you dump a bunch in, run the engine for 30-45 minutes, and the massive amount of solvent tends to slough off anything that might be clinging inside the engine. This, as you say, might be quite a bad thing - you loosen up a hunk of gunk, and next thing you know, you plug up an oil passage and everything grinds (literally) to a halt!

My understanding is that Auto-RX is a very dilute, slow-acting solvent. It takes 5000-6000 miles of driving to remove deposits, the idea being that the deposits end up being very slowly removed, and filtered out by the oil filter.

Again, I am not a user nor an apologist for AutoRX. Who knows if it actually does work? However, there are literally dozens and dozens of postings at "Bob is the Oil Guy" forums where apparently hundreds of people have tried this stuff, and it appears to work as advertised, especially on 'oil deposit buildup'-caused blowby.

Ill give that AutoRX stuff a try. For a few years before I bought my truck it was only driven once a week and just around town and move it to the other side of the street. The womans husband was injured on the flight line and didnt drive anymore so they had the truck for years for no reason. Then I bought it, and IP went out 2 months later and when mechanics and dealership couldnt diagnose the problem I let it sit for 8 months without running while I just kept driving my Camaro as usual. So I can imagine I have plenty of deposits in there causing a lot of what seems like blowby. Only 95K original miles on this engine, plan to have it for many years.

What I do not recommend is that compression restore stuff, I tried that, another reason I want to flush the system.

Ouch! That compression restore stuff, as I understand it, is some kind of semi-metallic product that is designed to 'melt' and to coat the sides of the cylinder wall in order to help the rings seal up and allow you to wheeze along for a bit longer before a ring job or a rebuild. I've never heard anything good happening from putting that kind of stuff in. Yikes!

There is a good chance the motor is just tired. I doubt this truck was well cared for judging by other things I see. I guess I'll make my final decsion when I have the CUCV in my possesion and can put the two side by side to see if stuff will fit. I'm not sure the serp belt setup will even work on the older style although I can't see why it wouldn't. I know the 4l80e will work with a standalone controller cause I saw one on craigslist that was setup with that. He used the compushift. Said it works fine although a manual valve body would be cheaper and some nice Lightening Rods....

I loosely toyed with the idea of ripping the cab and nose off and putting it on the CUCV. Then I reminded myself that I'm not 20 yrs old anymore. My wife hates my trucks, all my trucks except the Dodge. she was the one who liked it. No wonder it's been a POS....

Kenny, if you've been married as long as I have, you may finally be realizing that the truth is, your wife doesn't really hate your trucks. See, Kenny, after being married a long time (to the same woman)... Your wife actually just hates you... So thats the good news. YOu get to keep the trucks.

True...She's got pig flu right now, I told her to go visit her mother. That didn't go over well...

I have a neighbor that is restoring a 1963 Ford falcon. It has the original 170 CI 6 in it, and he tried Auto-RX to clean it out, as the instructions called for.
I was standing there when he started it up after the last drain and fill with fresh oil. The motor sounded like it had no oil in it, and had NO pressure. He shut it down after 20-30 seconds. Pulling the oil pan showed that the inlet screen to oil pump was so clogged up with deposits, no oil was getting through. After swapping out the oil pump, cleaning out pan, etc.. oil pressure is fine, but still has the blow by coming out of the draft tube constantly.....

Fix the 6.5 and sell it....talk to me about 6.5 parts for your CUCV later...I have a pile of 'em...
