So my eg8 has a d15b7 in it, I bought it, it kinda sat and I drove it here and there, got it legal and radiator went bad drove the car home hot as hell that day. So bought a new one, got it replaced it, elementary car stuff, started it and drove around the block like twice. Note: I did notice it started rough, where I went it started rough, when I went to leave....no start.. Oil had gotten into my spark plug cylinders....great.. So bought basically brand new ignition parts (spark plug wire set, spark plugs, valve cover gasket and grommets with the rings too) Next day....started rough still got to WORK..worked all day then clocked out to go home.. Car wouldn't start... Now keep in mind when radiator went out I haddddd to get home so she was running hot lol. And I went through every fuse, main relay, fuel pump works and is working properly with pressure too, grounds are good, everything's sparking...timing is good....anddddd found it.
my civic has no compression...
Not sure how which cylinders but by the way it was starting rough all those times something might be fried or what??
I wouldn't know what to replace when compression goes bad! Head?
Or is it in the block? Pistons etc?
Is it fairly cheap to go ahead and rebuild? Or is it ready for a d series swap that way I'm saving money from a b series having to get new everything when I'm already running d series... Thanks sorry it's a lot!

 

How exactly do you know it has no compression, but not know which cylinders? That makes literally zero sense. Do a proper compression test, and tell us your numbers for each cylinder. Then, do a wet compression test and give us those numbers. Since you overheated it, though, there's a good chance you blew the head gasket.

 

Could not have said it any better.

 

theres a 100% chance of a warped head. d15's are notorious gasket blowers, and you drove yours overheated. pull, machine, win.

 

Hmmm so you "lol" at the fact you warped the living **** out of your cylinder head?

Must be nice to have that kind of $$ to just waste on rebuilds...

You need to do a proper compression test as posted above, but we all know you blew the head gasket and/or warped the head.

Next time when the temperature needle of any car you are driving starts climbing past the middle market, stop the car and figure it out or call a tow truck.
