Had to pull the old 4runner over this morning and have it towed to the shop. It's making a godawful lot of clunking sounds, stops by itself all the time and I fear the worst. Before it happened, it had a bad regular klunking, knocking sound, but it was definitely worse at light gas or when I was letting go off the gas pedal. Any advice is always appreciated, but I'll probably hear later today or early tomorrow what the dealer thinks it is.

 

Does it sound like this?

I had the exact same problem happen to me about a week and a half ago. Turned out my rear main seal went out and was pissing oil out. I am in the process of finding a remanufactured engine right now. Good luck!

 

Nope. A lot more violent sounds with irregular intervals. Funny thing is, it seems like the engine purrs like a kitten except for the clunking.

Oh, no smoke or leaks as far as I can tell.

 

Rod knock. Common.

After you spend a bunch of time figuring out what a rebuilt 3.slow will cost, do the 3.4.
You'll be way further ahead than if you screw around with the 3.turd

If you've read this far, consider a labotomy

Obviously, the labotomy didn't work. Go back to chapter one.

 

Can you explain what this actually is? What does it take to fix it?

Thanks.

 

After reading a bunch of threads on the subject, I'm rebuilding the baby. Wish me luck. It's a small step up from changing cv boots and rear coils maybe
