1999 Civic D16Y7 Head Leaking oil / Burning oil
 

Ok Here is the long story 6 month ago, blew the head gasket and it was blowing coolant out of the radiator. Had the head resurfaced, valves resurfaced, all the good stuff.

While putting the head back together I forgot to put the valve seats / retainers prior to putting the valve seals on. So I did the dumb thing, and pulled them off and put them back on. I dont think it ever sealed just right.

Just the other day I was driving down the road and saw I was blowing smoke everytime I was accelerating. So thought I had a problem with the #1 piston where I installed those bad valve seals. tried the easy repair and swapped the valve seals.

Here is the bad part went from #1 burning oil to #2 and #3 also.
So I went ahead pulled head took a look inside and found had some oil in the intake manafold. Thought ah hold on maybe the oil is coming up from the pcv valve. Grabbed the pcv valve and it was clogged. went down to honda and picked up another one.

So here is where I am Right now. Head was all put back together with all honda parts from the dealer, valve seals and head gasket.
Trying to figure if I have a crack in the head or am i leaking threw the valve guide. I dought that I would be leaking threw the new valve guide seals.

I will post some pics in a little bit

here are some pics, this is after running the motor for about 30 minutes trrying to bleed the coolant system.

anyone have any ideas??
 

still trying to locate the problem, wondering if anyone has any ideas. going to look at the valve guides again to see if loose thi8nking that is the only thing that really makes any sense of where the oil is coming in from.

I'd start by compression testing the cylinders (wet versus dry, see link in my signature) and, if dictated by the results, a leak down test.

here is an update
 

compression ch shows #1 cylinder is down about 5-10 psi compared to the others. doing a leak down test showed they were fine also. but i pulled the valve springs and played with the valves and hooked up my leak down tester. Granted it is only a cheap one from harbor freight I threw about 90 psi on the cylinder and was feeling a slight blow by on #5 head bolt in the tightening down process. little worried about over torquing the head already at 55-maybe almost 60 lbs. I will post pics later of the bolt.

What were the raw psi values of each cylinder in the compression tests?

Also, I was not clear what you meant by:

But yeah, based on your test results, I would agree that bad valve seals or guides are probably the cause of the oil burning and leakage.

sorry I pulled the vavle springs wanting to check to see if the guides were allowing the oil leak. the dry and wet checks were about 5-10 difference on psi on the #1 piston compared to the other 3 cylinders.

oh ya, sorry forgot to post about 155 on the 2, 3, 4 and about 145-150

Yeah, focus on the valve guides and seals.

Smoke that gets a lot worse when you floor it is usually the rings. Compression test may or may not show that. If you get any increase "wet" (after putting a small amount of oil in the cylinder), really consider that possibility. A couple of people here have reported a similar situation. They replaced the head gasket after an overheating incident, only to find the engine burns a lot of oil from bad rings. Overheating is bad for the bottom of the engine too.

Drive a little then let the engine cool, remove the spark plugs and compare them to each other. If one has a lot more black stuff or raw oil on it that is the cylinder that is burning most of the oil.
