Engine Won't Rev above 2krpm and Smokes!
Hey YotaTech,
I've always appreciated the help I've received on this site and decided that it would be more than worth it to try to get more. Let's start with the back story:
My 86 Turbo Runner has 175k miles on it. I've done 99% of the work on it myself since I've owned it (it's been 4 years). Recently, the auto transmission started skipping 2nd and 3rd gears. It went from 1st straight to O/D. However, there were no issues with the motor. It did overheat a bit during the summer due to the fact that I couldn't find a fan shroud that would fit, but it was running very well for a 30-year-old truck.
About 6 weeks ago, I was driving the truck to work and it went from running well to running like complete s**t in a matter of seconds. I limped it home going about 10mph. White smoke was pouring out of the pipe and it wouldn't rev above 2,000 rpm without a pinging noise coming from the engine bay. I drove home at 1,100rpm. It honestly sounded like a misfire.
I took all of the plugs out when I got home and found quite a bit of oil on each of them, meaning that a fair amount of oil had found its way into the combustion chambers. I checked the radiator level and it was a little low but there didn't seem to be any oil in it. I checked the oil and found it to be a healthy color and consistency.
My questions are simple: What could this be and where should I start? I've done research on a blown head gasket and worn piston rings but the symptoms don't exactly match. What could cause oil to get into every single cylinder at once? I figure that doing a compression test will help out, but I wanted to see if the answer is obvious for the other, more experienced techs on here.
Thank you all for your help.

Sounds like a typical blown head gasket. The question is, how does it smell? As in the "white smoke" coming from the exhaust. Like coolant? If so, case closed.
Not sure why it even matters to know at this point. Best way to find out is to disassemble it. Which is bound to happen anyway. If you want it to run right again.

9n my truck which is a 91 3.0 one time I had it to where it wouldn't go over a certain rpm and it was smoking too was because I had gotten water on the computer and I guess it messed up the connection or something. But I unplugged all the plugs on it and let it sit for a couple days to dry it out then it worked perfect. This probably isn't what's wrong with yours being a different motor and all but I figured I'd share it just in case

Well...were delving into the short gap in my 86-95 Toyota knowledge which is the 22R-TE. But the 88 FSM shows a No. 1 air tube/air cleaner hose(air outlet to the throttle body, not the inlet from the air cleaner box). Which is where I'd start(if that's what you mean by turbo manifold, then yes, there). That should be how/where all the oil is getting into the intake. If I'm guessing correctly that it's turbo related. It's something I've only heard of happening. But never seen(other than googled pics), or have any experience with. Nor would I have a clue how to fix. Since the 88 FSM doesn't cover it. It just says replace as necessary(as in the entire turbocharger unit).
From the 88 FSM:
Good luck!
From the 88 FSM:
EXCESSIVE OIL CONSUMPTION OR WHITE EXHAUST
(possible cause) FAULTY TURBOCHARGER SEAL
(check procedure and correction method)
Check for oil leakage in exhaust system.
(possible cause) FAULTY TURBOCHARGER SEAL
(check procedure and correction method)
Check for oil leakage in exhaust system.
- Remove the turbine elbow from the turbocharger and check for excessive carbon deposits on the turbine wheel. Excessive carbon deposits would indicate a faulty turbocharger.
- Check for axial play in impeller wheel, and replace the turbocharger if necessary.

I hard to say. I might be totally wrong on every guess so far. It kinda seems like there may be a few things going on. Possibly any or all of the above? I dunno. I'm definitely interested in finding out. But that ball's in your court.

Yeah...there's a shop right around the corner. I might see if they'd be willing to come to a leak down test to see exactly where the issue is coming from. I'll keep you updated! Unfortunately, my motivation to freeze my a$$ off outside isn't exactly on par with my willingness to get my truck running again. This might be an early Spring deal...
