98 TJ 4 cyl ticking when cold

A buddies son at work has a 98 TJ with the 4 cylinder and it is ticking when he first starts it up. It ticks for a minute then stops and runs fine. I assume that its the lack of oil thats causing the ticking and as soon as the oil pump gets oil to the top of the engine it quits. Is there something that he can do to stop the ticking? It just started doing this. He has checked the oil level and it is OK.

Re: 98 TJ 4 cyl ticking when cold

If it doesn't do this when it's warm, I'd bet when it gets cold, the oil is thickening...you could try:

1. Engine pre-heater.
2. Oil accumulator.
3. Pre-oiler.
4. Lighter viscosity oil.
5. Synthetic oil.

If it stlll ticks... it's time for new lifters.

Re: 98 TJ 4 cyl ticking when cold

Some oil filters have an anti-flowback device in them that keeps the oil from draining back into the pan. This may help that. Although that is the type of filter I use and it still ticks somewhat when I start it. Rick

What filter has the anti-flowback device?

I buy Fram ToughGard filters. There is a little gasket/valve inside the holes that keeps most of the oil from draining into the pan. This is just a thought. LEVE probably has thought it through with all of the options. Rick

Everybody forgot about the best option. Get rid of that 4 cyl and drop in a 6 or 8.

Are you sure that it is even a lifter noise? I would check the rear exhaust manifold stud, and see if it is still there or broken off. This is exactly the noise a 2.5 will make when the stud first breaks. It may still be covered under warrenty. (80k)

Definitely make sure it is not exhaust manifold gaskets. A blown gasket will sound exactly the same as a bad lifter.

Re: 98 TJ 4 cyl ticking when cold

My '95 Trooper does this as well, has for about 90,000 miles now, and it's a common problem with the lifters in the mid-90's 3.2L Isuzu engines. The Isuzu "remedy" is to run Mobil-1 0W-30 oil in it, they call for that oil specifically. However, I tried it and it got a lot worse, so I went back to 5W-30. It does it a lot more when it's cold, and not at all in the summer. Eventually I'll just have it rebuilt, sorry I can't help more. I looked for a remedy years ago and came up empty.

None of the "quick fixes" or "snake oils" worked either, I tried a number of them.

Re: 98 TJ 4 cyl ticking when cold

Mine ticks too at startup. I'm waiting for it to puke so's it'll give me an excuse to swap in an 8. I don't worry about it..it's not that bad to me. My Toyota's got a solid valvetrain, so it ticks ALL the time.
