i know the oil pumpp works as i turn on the engine without the cover and lots of oil start to came out. lol promise i wont doit again...

That won't hurt anything, it's a good check for the oil delivery system.

whats next? what should i check for the white smoke?

Unfortunately the next step would be a compression check but I'm assuming your access to equipment is limited. You can also stick your finger over the spark plug hole and see if it pushes your finger off when you crank it. That might tell us if the compression is really bad. Hey, make sure the crankcase breather tube is open to the air and not plugged. That can cause all sorts of problems.

so what if i skip the comresion chek, unmount the head and piston and change rigs? wouldnt that give me better compretion and fix the white smoke issue? i have done that on my preview motorcycle, but it was a 2 stroke, if i do decide to do that just tell me wht should i be carefull for?

You should only have 750 ml ( about 3/4 quart) of oil in a GY6 engine..putting in a full quart will over pressurize the sump...and either blow gaskets and seals or cause blow-by etc.

Compression check first...just takes a minute and you can get a guage cheap at Harbor Frieght etc...make certain it has an adapter for a lawnmower sized plug...that is what these engines use...

Do the diagnostic first, these engines are far more complex than a two stroke...and get a shop manual, there are some on this forum. Do you know how to set the ring gaps and stagger them on the piston or hone the cylindar walls, set top dead center and mark the cam chain, align the cam sprocket, disengage the chain tensioner?...yes it matters...read the shop manual first...

Also see Bashan's tear down thread...

too late, a decided im messing with the engine to see if i learn somenthing, a took the head out and the piston, now im buying some rings to ut them on, any advice on the gaps?

[abispax]

Where you at there on the pic in question? It's the cam tunnel but I can't quite get oriented......the cylinder I assume. Can you back off on the shot a little and sharpen the focus? Rich

[abispax]

if i compare with your picture,should be at the bottom of the chain

2 questions...
1 on the piston, i see the word in, where does it have to face to the top or the bottom?

I bought some rings that are marked d and dy one its black and the other silver, does the black goes at the bottom and the silver at top?

and the camshaft holder, does the e x goes at the bottom?

thanks for any help...

I'm sorry, I still can't figure out what you're referring to in that picture. There's the lower cam chain guide slot but other than that there's not much there. I looked on a cylinder and head downstairs and didn't see any cracks, that can't be a good thing on yours.

IN is for intake side and it faces UP, EX is for exhaust side and it goes DOWN. Same for the cam bracket but it can only go one way, it hits the intake valve if you have it the wrong way.

Black compression ring goes in the middle of the piston, the silver on top. Any markings on them point up. Rich

how thick is the oil? and does it have a gas smell to it? maybe your valve seals/seats are bad and causing excessive oil leak? need more info...

its there a way i can check on those now that i have the head open?

[abispax]

ITS THERE a poorS mAn method to calibrate the valves without a the correct tool< i do not have a calibration tool>>> maybe use a can of soda? would that be thick enought? thanks for any sugestions

[Bashan]

You mean feeler gauges? Doing what you're doing you need them....pony up. Rich

[sprocket]

I have used Soda cans they are generally .003 ..from the side of the can...OK for valve gaps if you have nothing else, but feeler guges are like $4.00
