If your engine suffers from Blow By like I suspect it does, sea foam won't really do anything other than remove a little crap from in there - but it's not doing anything to put off the inevitable.

I did this, and now my engine is giving me a blue screen with lots of white wording, is that good?

Just had to...

BoostedE21 what do you mean by"suffers from Blow by"? Never heard that before.

its bad to drive around with seafoam in the oil. not as bad as driving around with dexron in there, but still, i wouldn't do it. Remove and replace the filter and oil.


blowby is everything that get's passed from the combustion chamber to the sump and oil after by passing the piston rings [and possibly leaky valve train]. it is BLOWN passed the rings BY the compression and exhaust stroke, and into the precious, beautiful motor oil. blowby is made of different states of matter, and the idea is that the engine once warmed up boils off the solid/liquid stuff and once this is gaseous, and mixes with already gaseous blowby, it is sucked into the PCV device and run to the intake manifold where it will be mixed with the air-fuel mixture to be burned away, and blowby.

I hope my engine doesn't have that blow by thing,it's bad and dirty enough as it is.Strangely it runs fine,no noises or smoke and it's smooth.Soon i have to do an emission test,hope this damn thing will pass,I plugged the scanner today and has no codes (only ABS which i hate anyway).Is the grade of gasoline going to make a difference for the test?I use regular on it and it's fine,no detonation or knocking.

Blowby won't really make any noise or make you fail an emissions test (so long as you have the PCV system in place). The computer won't detect it by itself, so it won't throw any codes. The problem with BlowBy is what it does over time. If your rings are worn, then you're letting combustion gasses through to the bottom end of the engine. That's going to contaminate your oil and make that mess in your engine worse. And since combustion gasses are getting out through the engine and not all through the exhaust valves, you're losing compression, and therefore fuel economy and power. You'll still be able to drive on an engine with blow by, but you might want to run periodic compression tests to see where you are. Once one cylinder starts getting a lot worse than the rest or they're all quite low, you might want to start looking for an engine to swap in. If you're asking if the grade of gas will affect whether you pass your emissions test, probably not. Though I'd recommend premium gas, I would imagine the car's timing is set for 93-ish.
