I have a 2000 Toyota Tacoma 4wd, extended cab, manual shift, 2.7L with 163,000 miles. I have only had it a short time. It has a slight oil leak at the front of the engine
which I think is in the vicinity of the oil pump?
The main problem however is that the engine has a pronounced ticking sound that is worse when cold, seems to go away when at high RPM, usually but not ALWAYS returns at idle.
Here is the bad part. twice now when the engine is warm, I have started it and the ticking is more pronounced. It will drive, but will engine will quit when I let up on the accelerator. It will restart when I let the clutch out and compression start it. If I stop and let the engine sit for a couple minutes it will then start and run fine, as if nothing happened. Yesterday this happened, I was in traffic when it quit as when I pushed in the clutch, I let out the clutch to compression start and the tires skidded as if the engine was locked up. Again I let it sit and it restarted fine. I pulled into a parking lot, let it sit for a few minutes more with the engine shut down. I then restarted and the engine ran fine and I drove the truck 45 miles home. Except for for these incidents and the leak, the truck runs fine, idles fine, and develops full power.
The leak, the ticking noise, and the problem just described may not be related. I think the leak is separate issue. This can't be a one-off, I would bet it is a known issue.
