@cheaterboy16 Try using BG fuel system products.Adding BG to the crankcase oil will help de-carbon the internal of the engine.when you change the oil add a bottle of BG oil stabilizer.replace the fuel filter,with a full tank of fuel add a bottle of Lucas or BG fuel injector cleaner.inspect the engine mounts.clean and replace the PCV and box,which is bolted to the rear (under the intake manifold) of the engine block. rebuilding is not worth it.follow the instruction on products

@tsiskkkoj Find someone who is experience in head gasket repair.This engine feature a aluminum cylinder head. careful cleaning the head gasket,make sure the head and block is straight. You will need a complete upper gasket kit from fel-pro,change engine oil and anti-freeze.

Hi steve. I have a 94 nissan sentra 1.6 liter, 103,000 miles.

I checked to see if it has a blow by and it does. It's exactly like you show in this video.

When i have the engine rebuilt should i replace all the pistons and valve's or just the bad ones?

@cmariscal69 Most Hard Parts can be re-use,except for friction parts.Rebuilding an engine is surely rely on care-full inspection.The cylinder walls must be hone with the correct stone so the piston ring will seat itself seal to the wall.Most four stroke engine smaller than a 2.2 will experience blow-by due to a small circle of the piston rings.The small ring is not strong enough or can`t maintain its tension along the cyl wall during operation. So with time the blow-by will return on a rebuild.

@SteveXnycperformance Thank you so much steve. I really appreciate you're great videos and your advice.

No hard feeling. 4 cyl engine are econo-box not performing art(performance).If you are looking for performance look at cars with V6 engine are not likely to see blow-up like 4 cyl, cause V6 feature larger piston ring with more cylinder for even distribution of power making the engine last longer that OVER-HARD Working 4 cyl engine.

i have a 96 nissan altima gxe 2.4 liter i jus fix the valve cover gasket and the DISTRIBUTOR had oil in my DISTRIBUTOR but i no i have blow-by how do u fix it do u got to take the hole engine apart

[SteveXnycperformance]

@chris96nissan Yea, you will have to rebuild.whats the mileage?.maintaining a proper engine oil level is the only way to reduce blow-by cause by worn-out piston rings.
