K i did a comp. test on my b18c1 "oilguzzler" and they were all around 210 (209, 210, 210, 211). All of them got to 180psi easly in 4 compression strokes. So im guessing thats good? And one cylinder is really oily. So im guessing its the head? such as valve stem seals, or cam seals? Or even just bad oil rings?

So what exactly is your question? I see a few question marks, but nothing that can be referred to as a question in anything resembling correct English.

the compretion test is good is real good, about the oil it could be the O rins try changing then and see it you still got an oil leek..

 

Well my engine is guzzleing oil thats the problem. So o-rings as in the seal between the cylinder and head? its a vtec, so i dunno. Are leakdown tests that expensive?

Leakdown tests don't cost more than compression tests because they take about the same amount of effort. However, since your compression test results are good, a leak-down test may not show anything wrong either but it does not hurt to try.

 

But leakdown test tst the head for leaks right? as in valves, valve seals, gaskets, etc?

LOL, that's what I was saying when I first read it.

Compression seems fine. The oil could be from the valve cover gasket part that goes around the spark plugs leaking. Get a leakdown test the see what happens.

Mostly for the head, yes. If the problem is, however, coming from the little spark plug hole rubber seals, then a leakdown test would not show that.

 

what kind of sparkplug hole seals you talking about? like the ones where the valve cover connects to the spark plug "tubes"? Would it burn that much oil then? Like when i first got it it wasnt that bad dont think, but it just got worse and is still getting worse. I started it up cold and took the oil cap off the head and a good amount of air was coming out, like alot. then it warmed up and not as much was comeing out but a fair amount still comes out.

 

Your compression sounds fine. Try adding some oil in in each cylinder then doing the test again. If your numbers jump, that means your rings are shot. A

 

I have almost the same problem. Engine just rebuilt&gt;

My readings are:
1st cylinder 220
2nd cylinder 220 and up the compression tester pops if i crank it more than 5 times at 220
3rd cylinder 220
4th cylinder 130
miles of break in 500 miles so far lose about 1/2 quart to a quart of oil every 200 miles

Spark plugs look grayish

morning start up black stuff spits out of exhaust.

 

I have the same problem. they just did all the seals in the head, my plugs look nice and tan 'cept for the one cylinder which which looks white and flaky. I dont know, all the readings are good, all 210. One cylinder has a major "leak", if i drive it hard i loose at least 1 liter a tank. Itrs really bad when im in vtec. What do i do?

 

MAYBE BAD HEAD GASKET? IS THERE LOTS OF SMOKE COMING OUT YOUR EXHAUST WHEN YOU GET ON IT?

 

easy with the caps there buddy. Ya its real bad when i let 'er loose. Everyone that i race complains b/c all they see of me is a cloud of smoke. But its only in one cylinder that i can see, and the oil is IN the clyinder.

 

If it was the headgasket wouldn't you be losing coolant? Which would cause the car to overheat.

 

Ya, my teg hasnt lost a drop of coolant, and never overheats.

 

try a valve cover gasket kit. comes with grammets and all. maybe tha's what the problem is? worth a shot. you can do it urself. and they only cost about 30-40 bucks if you shop around for good parts! good luck

 

If it was a valve cover gasket, oil wouldnt be able to enter the cylinder would it?

Correct. The valve cover gasket is just that... it s the gasket between the head and the valve cover up top. The Head Gasket is between the head and the block and usually when that goes you loose coolant.

As for smoking a lot, in my old car it was a bad valve seat. The valve was a little bent and over time it chewed up the seat where the valve sits and oil was able to get into the combustion chamber so I smoked like a *****!! and burned oil.

So it may not necessarily be the rings but instead the valves on the head.

But the only real way to tell is to get a leak down test to eliminate the rings as the culprate. If that comes up fine then I'd say tear off the head to see if the valves are okay. Your compression #'s look good though.

Good luck!

 

A leakdown test would find out if the head was leaking though. Compression test is for the rings, leakdown is for the head. If i did a leakdown test it would find out of the valves were leaking or something else with the head was. I know its not the rings now, unless its just the oil rings but i highly doubt that.

 

It could be the rings

 

Even with the compression that high? Im thinking valve guides....

 

looked at my manual and it said for my b18c1 stock compression should be 270psi? and its 210 isnt that bad? Like loosing 60psi is prettty big difference isnt it?
