The compression test will show if you are leaking compression, and if so, the leak down should help you identify whether or not the leakage is an issue with the rings or the valves. You should be able to borrow the leak down tester and compression tester free using the AutoZone, Advance Auto, or other major auto parts store's free tool loaner program.
If the compression test shows good compression on all 4 cylinders, oil may be bypassing the valve guide seals and being sucked into the engine during the intake stroke and making the smoke.

Ed, once again you prove to be the voice of reason and wisdom and that is 100% right. If budget is a concern then wouldn't make any sense to do that without a need to do so, I was kinda just thinking of my own preferences which is to take things down and confirm so that I know what is in there and going on instead of wondering, apologies if it came out any other way.650ed wrote: Pulling it apart is fine if there's a problem, but to me before doing that one should try to identify and diagnose the problem. For example - once the cylinder head is removed it's too late to test the compression or do a leak down test to diagnose the problem (assuming there is a problem), so if in this case the smoke is caused by bad valve guide seals one might end up boring; honing, replacing rings. etc. even though those items might be perfectly ok. Even though doing that extra work might not hurt anything, it might not be a good thing to do if the budget is tight. Ed

Not necessarily; but it might smoke. It would depend on the severity of the problem. Ed
