Bad cylinder no copression at all....

[jimmybean21]

I'm picking up the wagon today they say I got a bad cylinder. I believe they said cylinder 3 I'll find out for sure once I get it. They said no compression at all in that cylinder. Is this a easy fix or do I need another motor? The say I'm better off getting another motor. What do you think, any idea's???

[f22a1accord]

they are prolly right. you should pick up another motor so you dont have to go through paying out the ass to fix the old block.

there pretty much right your either gonna need a new head or block depending on why theres no compression,could be pricey or it could just be one or two bent valves! only way to find out is to take the head off and see whats wrong!

perform a leakdown test to find the part causing the lack of compression.

as above, could be something small. better to check then to just toss the engine.

I'm at the shop no where I did my swap in my LX to get that leakdown test down he is thinking the same thing. I'm praying its something simple not thrilled about buying another motor right now. If I have thinking bout another H22 that will give me a auto and 5 speed H, but we will see.

i just left the shop got the leakdown test done. he saying i got burnt valves and i can fix it by replacing the head. anybody gotta opinion on this?

[madwagon]

replacing the head (with a good, used unit) will almost surely be cheaper than rebuilding the one you've got. (Cause if you're gonna rebuild it you may as well redo the valve guides too (unless they're magically in perfect condition) and that adds a lot of expense.)

thats what i did when i burt a valve in my cb it fixed the prob so good luck man

ok thanks sounds good. will a F23a1 head fit?

Check and make sure you dont have a burnt valve first. If its just that then replace it and call it a day until the next problem occurs.

a1/a4/a6 will all fit. the a6 has a slightly different cam that's good for a little HP boost. (2-3hp with no other mods done to engine)

it a A6 in the car now. how hard is it to replace the burnt valve and how do i figure which one it is.

[Mitch]

Your best bet is to get the machine shop to replace the valve and resurface the head if thats what it is.

it was cheaper for me to get a used head that get it worked. i would go pull a used one look at the valves make sure they all look good and give that puppy a good cleaning i used oven cleaner the crap just fell off it looked new
