I'm taking my motor apart to investigate a problem, and I have a real quick question. One of the bolts I removed came out just dripping oil and I just find it funny there being so much oil in the bolt hole. It's either the very front one or the one next to it on the passenger front of the intake. I've already removed the intake and the actual bolt hole shows signs of alot of oil and none of the other bolt holes have even a drop.. The problem I'm investigating is that out of nowhere It just started smoking blue smoke like hell. I mean it went from 0 smoke ever period to blue smoke pouring out the back. It baffles me because it happened so quick and you would think rings would be a slow gradual smoke but hey what do I know All input and help appreciated.
It's a 94 z28 stock and I have the obd1 cable if any data is needed also funny is no ses light and 0 trouble codes

 

What codes would you have thought would show up for oil being burned?

I have yet to see an engine with bad rings. Don't waste your time looking there.

If you have oil at the intake and you are burning oil, wouldn't it make sense to look at the plug near that intake bolt to see if it has signs of oil fouling?

Sounds to me like you had a bad intake leak. And that would point to the gasket. Bad rings would not show oil at the intake as it would not get past the cylinder.

 

The intake bolts screw into the heads but are open to the lifter valley on the inside. Oil can be in that area in normal operation. However, the oil there should only be a mist and not a heavy dose. That and the fact that you have heavy oil consumption indicates a problem with crankcase pressurization. Vapor from the right side valve cover is sucked into the TB and then into the engine to be burned. The PCV does the same thing from the lifter valley but feeds it into the intake manifold...

If the PCV were clogged or sealed shut, crankcase pressure can rise leading to oil being in unusual places..like on your manifold bolt. A clogged PCV valve would force the valve cover breather to try to evacuate all the oil from the crankcase and it likely couldn't keep up....

Your oil burning problem is harder to diagnose. While Mr. Speedy hasn't seen an engine with bad rings, I sure have. Rings can break, in their bores and cause oil to leak past. A leakdown test would tell you right away if that's a possibility or not. At this point, if the heads are still on, do a compression test on all cylinders and look for one or two with readings off by 15% or more when compared to the others...that's likely where your problem lies.
