Smoking when cold and at high rpms

[hype8912]

I just wanted some advice before I start tearing my engine apart. The problem is that my car smokes any time its cold and at high rpms. Not just a little smoke, I mean like a James Bond smoke screen. At first I was thinking rings or head gasket, but I did a compression test monday. The reading were
#1 - 200 psi
#2 - 210
#3 - 210
#4 - 210

So after getting these numbers I didn't think too much anymore that that was the problem. I noticed when I took the #4 spark plug out that it was totally saturated in oil. I looked down in the chamber and there was oil everywhere. So hooked everything back up and did a timing check. Timing was at like 17 1/2 so I bumped it back to around 15 - 15 1/2 advance.

I was thinking that maybe the valve stem seals are allowing blow by. What do you guys think could be the problem?

Also an update on my h22 build-up. I completely ran out of money as to what I was building. Times got hard, so I ended up selling it all. $4500 in parts sold.

Sorry bout your H22 project bro...I don't like hearing that, I know how exciting it can be to start it and see it through.

In regards to your question, I too am having similar probs on my 90 EX manual with 254K miles. I have not done compression check, but I should & will when I get time to work on my car. Been working on our other family cars now. Anyhow, I'm glad you have good compression, you don't have to worry about piston ring oil blow-by. Compression check will determine valve leaks too...don't they? I forget which is which...leak down vs compression test. Anyways, the oil in spark plugs it most likely your spark plug tube O-ring. You have to remove the valve cover, remove rocker assy, but keep it together by ONLY completely loosening bolts, but not taking them out of their holes...you'll know what I mean when you do it...otherwise the end caps will pop out sideways & you have to push it back together. Look under the rocker assy where the spark plug tube ends & you'll notice an O-ring for each tube...replace these. Replace spark plugs with new, since old are wet w/oil. While under valve cover...replace valve cover gasket and washer-like seals on top of spark plug tubes (cheap parts). Reinstall everything & torque rocker assy in criss-cross pattern with proper torque & valve cover as well...look procedure up in manual.

dude just follow the manual and i will show you what kind of test u got to do to see if the car has the valve seals or if are the piston rings.
i think u got to put some oil in the pistons and check the preasure. something like that. just follow the manual and see what it says.

Your compression numbers look good, a little high but good. According to my book standard is 178 psi.
As long as you did the compression check properly it would seem that your rings, valves,and head gasket are in pretty good shape. You didn't list it in your original statement so i'll ask you right now, if you could list exactly how you did your compression test, because if you did it wrong you could have gotten some false readings.
The proper way of doing it, is as follows.

1.The engine Must be at normal operating temperature, and the battery must be fully charged.

2.Clean the area around the spark plugs, then remove All the spark plugs.

3.Block the throttle wide open

4.Detach the coil wire from the center of the distributor cap, and ground it on the engine block.

5.Disable the fuel pump circuit

6.Install the Compression gauge in the spark plug hole

7.Crank the engine over at least 7 compression strokes, and watch the gauge.

Now how the compression builds is extremely important, because it can tell you some things that may be wrong.

The compression should build up quickly in a healthy engine.

Low compression on the first stroke, followed by gradually increasing pressure on succesive strokes indicates worn piston rings.

Low compression on the first stroke, which doesn't build up during succesive strokes, indicates leaking valves, or a blown head gasket.

Cool info. But do you imply cranking over engine using the starter motor? I've read that cranking for more than 30 seconds at a time can wear out your starter solenoid because it will cause it to overheat.

Could someone please confirm this? Is it better to just crank no more than 30 seconds at a time or crank it over by hand?

[hype8912]

7 turns on the engine is like 10 seconds. Then its going to take you a few minutes to switch over the gauge to the next hole.

I did the compression check exactly how you described. I disconnected the coil plug on the coil. Disconnected the main fuel relay. I know everything was warm cause I did the test as soon as I got home after driving it. The tests would build up to about 180 to 190 on the first stroke, then slowly go up from there. I took all the spark plugs out and left them out till I was done with the test.

180-190 psi on the first storke, is very good, and it would seem that your problem isn't with your piston rings.

One thing i would do is replace your PCV valve if you haven't recently. I have actually had some cases where a car was burning some oil because of a clogged PCV valve.
But not any cases where there was a ton of oil being burned, but it doesn't hurt just to replace it.

[hype8912]

PCV valve is good, that was one of the first things I tested. I just put my finger over it a few time to see if the idle changes. Also cleaned it with some degreaser to get the oil off.

I only have oil burn out of cylinder 4. I may just take the head off next weekend and do a visual inspection. I was already thinking about taking the intake manifold to clean the egr ports.

mine does that too, changed the valve seals and it still does it so it is probaly the rings

yea i have the same problem too my car has just had the valve gasket replaced and the rings around the spark plug area replaced and when i was driving home from school my friend driving behind me said he could see it smoking ,and every month i have to add 1qt of oil for some reason i don't know.(maybe it is burning the oil but when ui start it off i don't see it there is no blue smoke. maybe only when im driving.
my f22 pisses me off i want to get rid of it for an h22 this summer hopefully i can pull it off.(heh)
