no compression
99 honda accord 2.3L. this is my brothers car. he said he was driving and it died out. now its a crank no start. i thought broken timing belt so i pulled valve cover, the belt seems ok and the valvetrain looks like its moving as should. checked compression found 0psi in all cylinders. what would cause no compression on all cylinders all of a sudden. i think its a cylinder head issue but cant pinpoint. the one thing that scares me is theres no oil on the dipstick. not sure exactly how low oil is. any info appreciated.thanks

Seems kinda odd that it would have 0psi on all cylinders instantly like that. So it went from driving fine to not driving at all?
Have an air compressor? A leak down test will let you know where the air is coming out.

yeah he was driving it yesterday when it died. towed to my house and its cranks but sounds weird when cranking and has no compression all 4. ive turned it over manually and valvetrain is moving and pistons moving. rotating assy seems to be in sync. i cant imagine it jumped that far out of time to get no compression at all. i dont have a leakdown tester at home with me.

do you mean a second compression gauge. no i only have one in garage other at work. or do you mean another test method ie leakdown test

1. Like above, I'd also try to get a 2nd compression test gauge or somehow verify that the one you have registers.
2. and I'd go buy 2 qts of el cheapo 5w-30 oil and add it to crankcase.
why I don't know, seems like damage has been done, but $6 would be worth some peace of mind.
(You say it sounds weird when cranking ... hhmmm no oil at all sound?)
luck.
