Just changed my oil again... after only 200 miles the Oil was very dirty. Like I said b4 I dont think the previous owner changed the oil much.


I used Gunk engine flush and I put in Moble one synthetic along with about 2 ounces of SEA FOAM in the motor.

When i started It up after the change I noticed a liquid discharge from the exaust with a dark black Crud in it. WHAT THE HECK WAS THAT????

 

prob all the carbon build up you had.

 

sea foam does that.. it eats all the carbon and sends it out the pipe.. you can pour water down the carb like a 1/4 very slow and it does the same thing

 

you can also try runnning a can of MOA with your next oil change. that stuff works great.

 

what is MOA?

 

NM i found it...

 

should i put more that 2 oz of sea foam in the motor?
it calls for 8 but i am not so sure about that.

 

I have used Sea Foam for a couple years now in various engine types. I love the stuff personally. WOrks better that any of the other bottled cleaners I have used, and actually does what it says.
Normally I suck it into the engine and stall it with the sea foam through something like the brake booster vacuum hose. Let it sit in the warmed up engine for the recomended time and start it to watch the fun. Burns of massive amounts of crud in some engines.

When it comes to putting cleaners in your oil, BEWARE!
If the engine has large amounts of sludge, you can cause a STROKE in the engine. Breaking free clumps of sludge can block flow in heads and low pressure areas. I start cleaning engines on a regular basis after rebuilds. This insures that there will be no build up.

Making sure that your engine runs hot enough and you use a good grade oil prevents this all from the beginning too. But, I think like me, that most of us on here are not the original owners. So who knows what the last idiot did.
