So this was a system that sprayed the water as you drove?

Yes. Once boost came on, the pressure turned on a pump, putting a small amount of water in the intake. Some people used a mix of methanol and water. We used a mix of acetone and water.

Water, acetone, and methanol injection, as an anti-knock method, was developed before WW2 in supercharged airplane engines. It allowed higher manifold pressures, especially for combat power.

I have caught a good bit of what looks, feels, smells and pour's like pure oil in my last 200 miles. I have caught probably a couple of ounces. I could not even fathom that going into my intake. The Customer service and individualized attention I got from Steve at EE was some of the best I have ever received post sale. I would like to get Blackstone to analyze a sample of the stuff for s***s and kicks

I tend to think the 0-20W oil is too light and making it easier for oil to travel to the intake. But then again I used to put straight 90W to slow down oil burning Vegas.

A friend of mine that was an engineering director for Honda, use to have a couple questions when engineers provided a position without explanation. "Why do you say that? And, how do you know that?"

 

When people think about it, they often can explain the first question. The second question is the tough one.

That reminds me, I need to change the oil in the truck. M1 0-20w is in stock in my garage. Interesting...I went to the Mobil 1 site and it has a search engine for finding the recommended oils for my truck. I punched it in and the third oil in the list is M1 AFE 0-30w

0-30 sounds better for warmer weather. It's 95 here in Ohio today. So do I put catch cans on my trucks? Seen minus 9 here last winter?

100 degrees here today,0-30w would be good for this weather. Seen minus 9 past winter colddd! My trip to work is 6 min but I let truck warm up. I guess my question is do I need a catch can?

Here is an article from gmauthority.com with information from Super Chevy that talks about oil in the intake manifold on a Corvette. I realize the engine in the article has a dry sump, but it is basically the same engine used in our trucks. Thought you guys might find it interesting.

I found a bunch of oil in my intake tube when I recently opened up my airbox. Even with my catch can. This was all clean-side blowby.

 

Needless to say, I got ahold of a RX clean-side separator kit ASAP. I will be installing it this weekend. Video to follow.

Yes, do it. I had the same issue until recently. I was going to change my airbox filter and found a nice pool of oil in the tube and even in the airbox. and a bunch of dried oil on the actual filter. You can hear the surprise in my voice when I open up the airbox haha

      J&L OIL SEPARATOR CO

      By Grumpy Bear · Posted

      Just did an injector/HPFP replacement on Pepper at 192,400 miles; close enough to 200K, RIGHT? (If 200K is considered life end and to me it isn't). But hey, to each his own.    Have never run a catch can on this vehicle. Back side of every valve looked like a new valve spray painted semigloss black. Port walls looked 'neat' (all a normal result of passive EGR via VVT) Zero build up even in AFM cylinders. Just color. It uses no measurable oil and never has.    At 155,000 I put her on E-85 and a borescope of the cylinders at plug change showed very clean pistons and valve faces. The replaced injector tips looked new. (It was the pump piston seal that was leaking). Oh well, have six good backups.    Still gets 28 mpg on gas (highway average) and over 20 (highway) on alky. UOA's look good and runs as good now as it did when I bought it. Better in fact.    What improvement would a Catch Can provide this motor?     And given all this I expect that IF I installed one I'd see some water/gas/oil vapor accumulation. Byproducts of normal combustion.   Having said that, IF my motor used an appreciable amount of oil I'd consider it a useful 'crutch' until I had the situation corrected OR if bore polished, until I junked it or rebuilt it to stave off repeated plug fouling.    I'm not telling you what I THINK. But what its DONE.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By Grumpy Bear · Posted

      Love the look. I'm a SCSB lover myself.    Two items. 1.) A spacer changes scrub radius but this also changes when we use wheels of different offsets. A little isn't a big deal. 2.) Steel wheels, alloy wheels all have different thickness. Same effect on the stud and lug nut as a spacer. When hub centric the wheel isn't supported by the stud. It's supported by the hub. The stud just keeps it all together.

      2016 Sierra 5.3L L83 new injectors now runs rich.

      By JAI3 · Posted

      I had a evap sol go bad a couple weeks ago. . I replaced it.  While watching live data at the time I saw I had some cylinder 1 misfires. No MIL but on live data I could see ~50 at startup and about 70 more after an hour a drive all on cyl 1.  I also noticed that the LTFT were -5% to -15% always.  And that bank 2 is always -3% richer than bank 1. Even across all driving modes, city, highway, etc it’s always 3% richer than bank 1. So I start with the misfire. Swapped coil, plug, and plug wires from 1 to 3. No follow. I got an Injector reseal kit, pulled the D/s injector rail, swapped #1 and #3 injectors, resealed them, reinstalled and retested.  The misfire followed to 3. So I ordered and replaced all 8 injectors, spark plugs, and plug wires. Also replaced the 1 time use fuel pipes under the intake manifold.  Injectors that were in the truck since new were  Part # 12668390.  I replaced them with # 12742701 Got from RockAuto. Pretty certain they’re genuine and the correct ones. I called a friend at a parts store who told me “the 12742701 were the correct superseded part # for the originals I was replacing”. So started truck after replacing all that and it’s running -15 - -30 LTFTs. I reset the fuel trims with GDS2 and drove it for a 60 miles trip each way. There have been no changes in the LTFTs.  I checked if the HPFP was leaking into the crankcase. I removed the pvc and watched the trims. No difference.  I checked the alcohol content and it was at 10%  I’m out of ideas here. Truck seems to run great. Just always rich on the fuel trims.  Anyone with any help or ideas would be greatly appreciated.  I ran an injector balance test just for the heck of it and it came back this. I’m confused.  I have gds2 and some other diag tools if anyone knows of anything I should test next.
