Default Compression help

Block is at TDC cyl #1 and this is what the pulley looks like,Cams look as though they are on time. I remember reading about crank snout problems but I thought that this was only from the earily ones. I would have love to see a broken timing belt =( 0 compression. Any help would be amazing. Cams 100% in time. But I think the crank pulley moved? I honestly do not know. Car just cranks with 0 compression.

For a question like this you need to be more specific. does your guage work? Did you test with a guage or are you guessing it has no compression, timing belt may be stretched to all get out, you may be checking the marks while turning the engine anti clockwise instead of clockwise, no pulley can slip.

The harmonic balancer can which will show correct timing when it isnt, but its easy to tell, put a screwdriver into the no1 plug hole and crank manually until its at tdc with the cam marks lined up, no wyou will know if the balancer slipped.

car cranks like no spark plugs are hooked up. intake has a nice amount of oil.
i did a leakdown on cyl#[email protected] with out plugs in the motor, there was air coming out of cyl #2s plug hole. Then i realized there was a good amount of air coming out the intake with #1 both lobes pointing out.

Do you have stock cams/gears in it? Got any pics with the valve cover removed?

You can try disconnecting the belt and turning both #1 cam lobes up away from the valves then try a leak down again.

It could also be jacked up valves, but kinda unlikely on all four cylinders?

They look closed. How's the lash? If your getting leakage from the intake, it has to be in the valves.

Indeed, while it's certainly possible to remove the engine while leaving the transmission in, it's very annoying to get the two separated in situ. To be specific, a couple of the bellhousing bolts are in a really awkward spot.

Some folks actually prefer to pull the whole engine / transmission combo just to do a simple clutch job.

So cylinders 1&3 are filled with oil, 2&4 are ultra clean, I know the car ran without a radiator fan for a while and the is some heavy tan sludge in it. Going to pressure test the head and go from there.
