Honda crv 2002
I changed my head gasket now my compression is
at 120 120 120 and 90 still blowing smoke and
spark plugs are still white what's going on
The Head is cracked. Who ever replaced the head gasket should have checked this before replacing the head. Best of luck
Still a problem on the cylinder with the 90 lbs, as Sixfoot suggested the head might be cracked or a real sloppy job of head shaving when the heads went to the machine shop for testing and milling.
I see no visible crack at all :( anyone no what the compresion should.be on a 2002 2.4 Lee honda crv
From what little I could get from Hondatech it should be no lower than 135. You may not be able to visually see a crack, that's why they need to be checked and milled.
Could the PCV valve cause this when I bought the car compression was even at 150 now replaced head gasket and I'm at 120 120 120 90 I don't get it it runs awsome just smokes horrible
How can it run awesome with one cylinder below minimum compression. A PCV valve is not even active during a compression check, even if it was stuck wide open you might get a higher idle and a code for unmetered air.
That why I am confused I bought the car and compression was at 150 150 150 150 she said the head gasket was blown which I confirmed stuck.it.in a trailer hauled it home replace head gasket and valve guides start it smoked heavily took it around the block twice smokes horrible shut it down checked compression it was 120 120 120 90 but the engine sounds and runs great that's why I am confused
So were the heads checked for cracks and then milled or no check before they were milled?
Everything was checked :( im so confused
Then though it pains me to say but your going to have to tear it back down and find what went wrong or was missed. Could be anything from a creased gasket, too missing something during the head work. UGGH sorry
Valve in bottom of intake got stuck
I'm surprised it even ran with that open.
Okay so we are up and running but now I have new questions lol I'm getting a knock sensor code what's that and also when idle the oil light flickers but the car runs prefect rims are great no smoke help me :)
It could be the knock sensor wire is not connected, look around for a wire hanging loose, oil light flickers could mean low oil pressure or just a bad sender, you might have to install a manual gauge to verify if it is low oil pressure or just a sender malfunction.
Replaced knock sensor also replaced oil.pressure switch wish me luck !!!!!
Thanks for all the help were up.and running with no issues
