Hello I just bought a car from someone that said the motor was fully built the car is not tune. Me being dumb I drove it to make sure it doesnt die out or overheat. It was fine so I bought it the next day I was changing my oil I notice the oil was milky... so I changed the oil and did a compression test number was 40, 60, 70, 80 acceoss the board. But the motor idle fine and sound fine....

its not fine do not run it anymore blow headgasket and hopefully not ruined piston rings

 

So you think its the head gasket? If so I will run to autozone and rent the tester for the head gasket checker

 

theres nothing to test if your oil is milky then its blown

 

Replace gasket replace oil do an oil flush

 

you also might want to double check if the autozone hg will work. correct me if im wrong, but a b20 hg wont work on a 84mm gsr block

 

I will just order the golden eagle brand

 

my motor is idling fine and not over heating when park but what I dont understand is would I hear are notice anything wrong if compression test number was 40, 60, 70, 80?

 

I called the guy I bought the motor from and he said it never over heated on him, he said the car sat for 2 month only before he sold it too me but that doest explain the very very low compression test it doest make sense

 

Healthy MINIMUM compression numbers are 135psi. Your numbers are beyond past bad at this point or you messed up the compression test badly. A blown headgasket doesn't necessarily have to cause the engine to overheat either. Keep driving it like that and you'll be sorry. Change the damn headgasket.

 

Hahahaha guy selling was so stoked you didn't pull out any test equipment and baught cause it ran :p

 

just remove my head at least the guy was right about the block is being built...

will finish puting the new gasket on next sat hopefully it will bring the compression back up. What is a good compression for 8.5:1?

 

Does those look like Darton sleeve?

 

Check the block and head with a flat edge, make sure the block or head isn't warped.

 

How do I know if the sleeve are sunking?

 

They would be sinking.

 

I know that.... the sleeves are lower then the block how will I check it?

 

Precision straight edge and feeler gauge.

 

so I do it from the block over the sleeve? if so the sleeve part is lower then the block already.

 

Just A thought, I wonder if you can get the block resurfaced to the sleeves (if in service limits)? If anything you need to find out how much lower the sleeves are, Im sure this is bad...

 

Should it be flush or not?

 

Your spelling and grammar makes me want to beat retarded children...

Those are dart on sleeves, everything looks fine, clean all of that **** out of the cylinders and put the new gasket on already..... the questions you're asking we can't answer unless we can physically touch the damn motor

Install the damn gasket already and go from there

 

looks like GE sleeves to me.

 

Clean it up nice with air and rags. I hope it works out for you. Nice block.
