Low Compression?

Is there anything else I need to do? Like disable the ignition or anything else for testing compression?[/Quote:710a27240a]

Go ahead and remove the PGM-FI main relay. Then do your dry and wet check, makes sure you remove all the sparks plugs and mark the wires and also block the throttle plate wide open-[/quote:710a27240a]

Can I just hold down the gas pedal all the way when cranking the engine instead of blocking open the throttle? Also when doing the wet test, do you recommend using any special oil like marvel mystery?[/Quote:710a27240a]

You cannot be in two places in one time get a helper while you look at the gauge-10W30 will do it.

You need to puff it atleast 5 times[/quote:710a27240a]

So is that a yes, it will be sufficient to have a helper press down the gas pedal while cranking and me looking at the gauge?
How much oil am I supposed to put into each cylinder?
Thank you for your responses, I really appreciate it.[/Quote:710a27240a]

Have the helper do that
Put oil in a squirt bottle and hit it 5X[/quote:710a27240a]

I have bled my brakes twice now, and when I press on the brake pedal I still feel it sinking to the floor slowly. Could this mean that my brake master cylinder is bad?
Thanks

How should I find out whats causing that cylinder to be low? I dont wanna just tear into the engine and have to buy replacement gaskets for everything if I dont have to.

If your foot is sinking gradually it points to the brake Master Cylinder-[/quote:e4b2754571]

I just ran the compression test. For the dry test the results were: cylinder1: 195psi (6 cranks) 2: 200psi (7 cranks) 3: 200psi (8 cranks) 4: 200psi (8 cranks)
wet test results: cylinder 1: 220psi (7 cranks) 2: 230psi (8 cranks) 3: 230psi (8 cranks) 4: 230psi (7 cranks).

I know you told me that it should be reading 125-135psi on the dry test. Why do you think it is consistently reading so much higher?

My 93 honda civic ex has the d16 1.6 liter sohc vtec motor with 185k babied miles. The car was parked for 2 years and only run occasionally but with no problems. It was last started and driven a month ago and ran like a champ but now it turns over but will not start. It's getting fire and fuel so I pulled the plugs and have no compression in any cylinder. I checked the timing belt and it is in good shape and has not jumped time. When I turn it over with the valve cover off the cam is turning, valves are opening and closing but for some reason will not start. Also oil is pooling on top of the head by the no. 4 cylinder and not draining back to the engine. Ther is no coolant in the oil or oil in the coolant so I don't think the head gasket is blown. I am a decent diy mechanic but am stumped by this problem. Any feedback will be greatlly appreciated.

'91 honda civic, 160,000 mi, 4 cylinder. My '91 civic has no power. Friends tell me that its my piston rings or valves. They say it would probobly be best look in junkyards for a newer engine. Does anyone know what engine would be a good choice? A more modern civic engine? I don't know what would fit/bolt on the same way. I know nothing about cars.
