+1 for seafoam!!

ok, so i needed to change my oil and i've had this nagging suspicion/fear that i have some sludge buildup in my engine. so, i bought some seafoam and put about 1/4th of it in the oil and drove 20 minutes to my parents house to change the oil. before i shut the engine off i take a hose and start giving the engine the magic stuff. ended up sucking down the rest of the bottle, oops ohwell. 'bout 30 minutes later when the oils changed and everythings all buttoned up i go to start the engine and get all the crap cleaned out, take it for a ride and hold the engine at 4500 for 15 seconds (in the FSM) and continue on to town to get my hair cut. the car felt a bit "peppier" but i didnt really notice how much power it gained until i floored it from a standstill and smelled the wonderful aroma of tire smoke... LOTS of tire smoke. i tell you, that engine hasn't done that in a long time. seafoam is a MUST HAVE.

I think I would seafoam the intake, THEN change the oil.

Don't matter which you do first, or that you do all 3 steps, but there is 3 steps.

Step 1 is 1/3 of it in the crank case as per the instructions (cleans internals)
Step 2 is 1/3 down the Throttle Body. there's a vacuum hose on the top of the TB you can use. (cleans intake system, valves and cylinder heads)
Step 3 is 1/3 in an 1/4 tank of gas, fill the tank, drive (this cleans the fuel system)

I haven't done Step 1 yet, but I have done step 2 (but used MCCC) and step 3 with seafoam. Definitely a noticeable difference.


The only thing dependable about the future is uncertainty.

Yes, but to clarify my comment above, Seafoam is a cleaner not an lubricant. So do all your cleaning and then change the oil rather than the other way around. Also I wouldn't run Seafoam in the oil for a long time. Pour some in before your oil change, run it some (perhaps 100 easy miles) and then change your oil.

Seafoam FTW!

(Just dumped some into the gas tank last night, as a matter of fact!)

1G engines put out a very prolific amount of smoke when run through the intake, BTW.

I just did this to my car after reading this thread, my first time. The idle seems a bit smoother and the car seems a bit more responsive when accelerating from a standstill. It still didn't fix my hard starting problem, probably the fukin fuel pump..

Sea Foam saved my butt when I did my 2.7 timing chain a couple of years ago. I did my valve stem seals at the same time, and used compressed air to hold the valves up. My compressor doesn't have a trap or drier on it, so a good bit of moisture went into the cylinders while I did the work. When I went to turn the engine over by hand near the end of the job, the pistons would hit a soild wall just before TDC. Took a bit of head scratching, but i finally figured out that the carbon on the pistons and head absorbed moisture and swelled so that there was interference. I had trouble believing it, but that's the only explanation. I poured a measured amount of Sea Foam into each cylinder, let it soak for a few minutes, then used a plastic tube taped to a vacuum hose and stuck down each spark plug hole to suck out the Sea Foam and dissolved carbon - repeated 3 times. The dark black stuff going thru the hose got clearer each time. Darn if that didnt eliminate the interference.
