I found too much engine blow by today I mean it was like fan you could feel the wind from the top of the hood. This was found this week i never notcied it before but I did get a oil change at fire stone last week aswell. They said they wanted to by syntic oil but i wanted the cheaper regular oil that was on sale for 20$. Quakers or some brand like that.
What i think im gonna do is go get the compression tested and see what i can learn from it. Also maybe switch the oil to syntic but i think its too late for that anyways the damnge has been done. But yet again I dont know how long this has been going on for . The car is a 2007 honda accord VP with only 120k miles 4 cyl v tec. anyone know what kind of oil i should have in it and would it fix my blow by problem ?
post ur comments below !!! ::(

If the engine has a ring induced blowby problem then the oil type is not going to matter much. You could run a heavier weight oil but that may then cause problems with the variable valve timing mechanism.
I’d get the compression test done and go from there. You should run both a dry and wet test. If the numbers are abnormally low and if they take a jump upwards during the wet test this means the piston rings are gone.
Ideally, what you want on a good engine is about 180 or more PSI per cylinder.

I guess I’ll give it a try I hope autozone lets me use it for free ! Also what oil would i use for the wet test ? the same one already inside ? I saw on eric’s video he used some red fuild which i assume is tranmission fuild.
You can use any type of oil on the wet test. Do not use too much though. A teaspoon of it should be enough.
Blow by is a mechanical internal engine condition where compression and combustion pressure gets past the rings into the sump. Changing to a different oil won’t fix it, and you don’t experience it as turbulence in the engine compartment.
The first thing I would check would be to see if the oil filler cap was re-installed in the top of the valve cover during the oil change. If that’s OK, then I’d suspect the electric cooling fan at the radiator was on when you were looking under the hood.

To make a point though, the engine probably would not have blow by unless it is run with no oil or no oil changes at all, overheated and warped or anything major like that. The only way engines would have that from normal wear is if it is really high mileage. If you drive the car and it doesn’t feel like you have to feed it a whole gallon of has to get it to advance just 5 mph higher on the highway, you probably do not have blow by. IF you really do have blow by to where it feels like a turbine under the hood, you would have oil all over the place and your car would not get vary far without having major issues.
