01-05 ping

[Tom @ Fast Forward]

We have had a couple of hotside 01-05 cars and a couple coldside 01-05 cars over here lately with ping that we were unable to correct. We did leak down tests on them hot and found in all cases one or more cylinders that had poor numbers (good cylinders would be 95%, bad cylinders would be 80-85%). In all cases we also found carbon build up on the pistons. Two of the cars we found the carbon buildup was there before the coldside was installed. If you have ping that wont go away on a hotside/coldside, the main things to look for are:


Carbon build up on the pistons.
A stuffed up cat.
Bad compression/leak-down.

I have seen it also on 2 engines 01+ where the owners have been running 87 octane instead of 91. in the long run this is the right way to ping and make dammage to the engine....

I just don't understand why anyone would cheap out on gas like this. How many times have people posted on M.Net asking whether or not they should run 91+ gas in their 01+ cars? Most of the time the poster is from an East Coast state where they have 93/94 gas!

[kompressorz]

Lol there are more CHEAP people out there than it looks like....

[Tom @ Fast Forward]

Well, in all fairness, it IS $0.10 a gallon more for 91 than 89.

There used to be a commercial (oil change?) that was based on "Pay me now or pay me later". What I think we have learned in the last couple months is that, 01-05 especially, looking for a three or four year old car with extremely low miles is not a good thing. They really don't like sitting around and doing nothing for long periods.

A quick and easy way to remove carbon deposits....

Remember how clean the cylinder is when you have a blown head gasket...

a little water inj. nothing elegant required, misting nozzle and washer bottle...

squirt it in AFTER the MAS and it steam cleans your engine.

I had a pinging problem when I first installed my coldside. I made a number of all at once so I am not really positive what got ride of it. One of the things I did was to use a product called Sea Foam, available at NAPA and most auto part stores. This product is said to remove caron deposits from internal engine parts. I actually got two bottles and treated my engine twice. I really think this is what cured my engine's ping.

Here is their product info:

SEA FOAM MOTOR TREATMENT for Gas Engine Applications

100% Pure Petroleum
Use in All Engines in All Seasons
2 Cycle, 4 Cycle, and Diesels
Treats 3 Critical Areas: Gas Tank, Fuel Systems, and Crankcase


Cleans fuel injectors
Cleans carburetor jets
Cleans carbon
Stabilizes fuels
Upper cylinder lube
Removes moisture in fuel
Removes warts and unsightly moles
De-icer
Frees sticky lifters
Frees sticky rings
Removes moisture in oil
Prevents bloating, passage of mucus or straining with bowel movements
Cleans P.C.V. systems
Cleans catalytic converter odors
Oxygen sensor safe


How Many Mechanics Use SEA FOAM
In Tune-Up of 4 Cycle Gasoline Carbureted or Fuel Injected Engines
Autos, Trucks, and Tractors
With engine warm, slowly pour 1/3 to 1/2 pint through carburetor or throttle body throat. (If vehicle is port injected slowly pour SEA FOAM through direct manifold vacuum line that will feed all cylinders, possible sources are P.C.V. valve or brake booster line.) This will pull SEA FOAM down on top of the pistons and to the back of the intake valves to dissolve carbon. Turn ignition off. Restart engine after 5 minutes. If severe carbon build up is apparent, use more Sea Foam as previously directed. Make sure exhaust is well ventilated when using Sea Foam in these various ways, as fumes will be extreme for a short time.
Pour 1/3 to 1/2 pint into oil crank case to clean rings, lifters, dirty parts and remove moisture.
Pour 1/3 to 1 full pint into fuel tank to clean injectors, carburetor jets, fuel lines and remove moisture.
Immediate Results: Smoother idle, increased R.P.M.'s better throttle response and improved performance. See label on can for detailed results for use in each area.
FUEL TANK, CARBURETOR, INJECTION and OIL CRANKCASE.

For Peak Performance, Use SEA FOAM Every 2,000 to 5,000 Miles

A 100% pure petroleum product for use in all gasoline and diesel type engines, both 2 and 4 cycle. OXYGEN SENSOR SAFE.
Cleans dirty engine parts internally by removing harmful gums, varnish and carbon. WORKS AND PERFORMS INSTANTLY.
Removes moisture from oil crankcases and fuel tanks.
Stabilizes and conditions fuels. Use for engine storage.
Cure hesitations, stalls, pings and rough idle due to carbon buildup.
Helps pass emissions test. EPA Registered.
When Used Thru Injection or Carburetor

Cleans carbon build up
Cleans intake valves and pistons
Gives smoother idle
Cleans catalytic converter odors
Cures hesitations and pings
Restores power and pickup
With warm engine running, SLOWLY poor 1/2 pint through carburator, throttle body or direct manifold vacuum line that will feed ALL CYLINDERS. Possible sources are P.C.V. valve or brake booster line. Turn ignition off. Restart engine after 5 minutes. Be sure exhaust is well ventilated. Fumes will be extreme for a short period of time.
For use in injector cleaning machines, use 50% SEA FOAM and 50% fuel.
Fill diesel filters with SEA FOAM to clean injectors fast.

One pint treats 10 quarts of oil (avg. 1 1/2 ounce per quart).

When Added to Fuel Tank
Cleans fuel injectors and carburetor jets
Cleans carbon as you drive
Lubricates upper cylinders
De-ices and removes moisture
Diesel full conditioner and anti gel
Stabilizes fuel
One pint treats 8-25 gallons of fuel (average 1 ounce per gallon).

In Injector Cleaning Machines

I have also used Seafoam to clean the pistons. It works great. However, find a place where nobody will care about the smoke. :) I simply pulled one of the vacuum lines and dropped the vacuum hose into the can and let it suck it into the manifold. As soon as the engine stumbles, pull the hose out of the can and put your thumb over the end to stop the vacuum leak.

Last time I did it, I went out into the desert off the US 60 highway. I ran a whole can through the engine. When I was done and the smoke cleared, I rolled back to the highway. Traffic cleared so I pulled out. As I put my foot to the floor, the world behind me disappeared in a cloud of white smoke. As luck would have it, when the smoke cleared, I could see the red/blue lights flashing a lot more clearly. ;) We have a "gross pollution" law here and he thought I fit the bill. I explained what I had done and he had me rev the engine and drive away hard. As no more smoke appeared, he let me go on my way. The moral to this story is, when you think the smoke is all done, there is still some Seafoam hiding somewhere ad, when you make boost, it will appear (or disappear as the case may be). Do it someplace where nobody cares. If your neighbors come around to investigate, simply explain that, although it is winter, you are fogging for mosquitos and getting an early start.

What a coincidence! I just got home from the local autoparts store with a can of seafoam. I was debating whether to add to the fuel take, or do the vacuum line feed for cleaning the cylinders.

I was wondering if it has any effect on the coating on the supercharger rotors? If added to fuel, it is injected after the SC. If it is fed through a vacuum line, it can go in before or after the SC. Which is the "recommended" method?

[Tom @ Fast Forward]

Put half of the can in through a vacuum line. On the hotside it would go direct to the intake manifold and bypass the SC. On the coldside you could still use the vacuum line at the front of the manifold on the side (the line that goes to the PC-Pro). Put the rest in the gas tank if you wish. If you inject it pre-blower, I doubt it would have any effect on the rotors as it is mostly diesel fuel/kerosene. Under vacuum, going in pre blower just goes in the BTB adaptor and through the bypass anyhow so not much would even get to the rotors.
