Intake clean. WOW!

[SlavO]

Lets see a pic of your trip from today to next week. In a week. Any 1 can ho drive 4, 20 miles on the highway and and start a trip vount going 50 mph like im dure your doing an get those numbers. .... show me miles after a week

No I did not. Did really feel like taking the intake manifold off again if you know what I mean.

 

 

Yes there was oil covering the inside of the intake.

 

 

I thought about doing something like this too but I think it might be pretty difficult. On the inside of the intake manifold, the runners aren't easily accessible because of a cylinder that starts at the throttle body and goes about half way back. Here is a picture from PickUPS in the "Oil Catch can?" thread showing the inside of his intake manifold. This is on a 4.3 but the 5.3 is similar. I don't want to discourage you from trying to get a camera down to the intake valves but just wanted to let you know that it might be tricky. If you get it to work let me know as I would be interested in getting one of those cameras then.

 

 

I know what you mean. The runners intersect the plenum at a right angle to the throttle body inlet also. It's a longshot, but I ordered a $35 borescope 1 meter long. I can always pull a plug and look at a valve that's open to see how bad my engine looks. More toys.

Huh?????

[SlavO]

Huh?????

Sorry, ive big fat fingers trying to type on my phone. All im asking is for him to to a trip counter with more then 400 miles a week average

[nahulu77]

OK.. I'm getting a catch can. There a thread for this? (I'm sure there is.. but.. I need to know how to

Just got a call from the dealership, they're ordering me a new a catalytic converter.

got this from the FAQ on the seafoam website take it for what it is worth......

I added a can of Sea Foam to about 12 gallons of gas in the tank of my 2002 Grand Marquis, then used ½ can of the spray in the intake. Now my car shows a “check engine” light that was not previously on. Did the Sea Foam somehow cause this? What should I do about it?

Jim’s answer:

Adding Sea Foam Spray Cleaner and Lube directly into the intake will, in some cases, trigger the “check engine” light due to misfires that occur while you’re spraying. The misfiring was only temporary, and you should be able to easily turn the light off by clearing the error code.

Grabbed 2 cans doing my wife's sonata and my truck now

Ok after reading this, but having now issues I tried it..... It was pretty easy but very nerve wracking to say the least. I used the CRC product since it is specific for the Valves. I sprayed it right into the Throttle Body while my Wife did the Throttle. While letting it soak, I did spray and wipe out the throttle plate area.

 

After the soak, I started the Motor but it started like shit. I backed out garage and when I drove off it was very sluggish and lots of crap out the Exhaust! My Driveway is 1200 feet long and just took it easy going down, but again very sluggish. I stopped and pulled out onto my country road which It bobbled a couple of times and get much better as I was just driving normal. Took it for a 15 drive at varying speeds and it seems fine.

 

I will no what and see long term if it had any affect...... Again, very easy but nerve wracking!!!! lol

I did the CRC before my CC install. Same conditions as you. I believe they recommend a good freeway drive after.

Strange thing happend with my wife's sonata. She has 30k miles I just put the can on. I did a whole can of crc let it set an hour and went for a spirited ride. Started normal. I pulled out into my development and when I got up to just about 3000 RPMs. I heard the loudest clicking noise as if somebody dropped a pin screwdriver or a pencil or something inside the motor. I was scared shitless but I don't normally I have no check engine lights or anything. So I made it out of the development of on the road and still when I had about 3500 RPMs a few click click click. I drove about 3 miles down to a country road and I was going to walk to see if I can hear it again. There was nothing so I got on it for a spirited ride and a few 80 mile an hour passes. No clicks no issues can't even tell the car is running at a stop sign. The same thing to my truck only get a half can since I only had 10 K miles and it had an oil CATch can on the last 5K. No issues at start up no clicks no noise in some fun country road driving it feels like the day I bought it. I am curious though about my wife sonata and that clicking. Couldn't have really been that gunked up in something broke off

Probably hard particles of carbon floating around in the cylinder

This is sort of what mine did. The first start after the soak was slightly delayed, it had to turn over a few more times than it normally does on a prepped start. It was also boggy at the beginning of my drive. The more I drove it the better it got though. The 2nd drive it was a totally different truck.

Sorta on the topic, but I have a theory on the 6.2 vs 5.3 mileage. The V4 mode in the 6.2 has a larger displacement as compared to the 5.3 in the same mode. In fact, the 5.3 has the smallest displacement of all:

 

4.3: 2.87L

5.3: 2.65L

6.2: 3.1L

 

So, the theory may hold that the 6.2 may be able to produce the greatest power in V4, and would, therefore, be able to enter V4 and hold it longer since the move to/from V4 is based largely on engine demand vs output. The 6.2 maaaay have sliiiightly higher pumping/frictional losses in V4, but I bet this is negligible.

 

As V4 mode is a big player in mileage, I wonder if this is actually a GOOD element with respect to the 6.2?

The normal driver is in V4 modes 10-15% of the time - not a big contributor. So 80-90% of the time the 6.2L is gulping gas. You're assumption that the 6.2L gets better mileage in any situation but maybe towing is incorrect. You are not accurately representing highway mileage when you reset your trip computer as you enter the highway on-ramp and then use cruise control for 20 miles. I can get the same or better results with my 5.3L. If you do a quick Google search or go to FuelEconomy.gov, you will see that highway mileage is actually calculated/tested as a doorstep-to-doorstep type scenario. There are stops, starts, cruising at various speeds (slow and fast), passing, running of the AC, etc.

 

Unless you run the same test several times with similar/controlled conditions before and after your cleaning, there is no way to prove that your intake cleaning was of any significant benefit. To simply put your cruise control on 70, reset your trip computer, take a snapshot and compare it to the 5.3L is misleading.

[darkfox1]

My 5.3 with 3.08 gears on the highway, reset trip meter once at cruise speed (78mph) for 150 miles gets 19.9mpg while going down hill and 19.1mpg while going up hill. (about a 1000 ft decline/incline over 150 miles.)

 

Oddly enough, if I reset the trip meter and tool around my daily driving. I get about 19.0-19.4mpg right now.

 

Prior to the cleaning I was seeing about the same highway, but around town was 17.9-18.4mpg.
