so adjusting the valves won't make a difference?

 

Eleven years later, and the valves still aren't adjustable because they use hydraulic tappets.

 

I pinned all 8 about 3 years ago following the lead (and posts) from others on this forum. The loud ticking at idle immediately disappeared and has not returned. A few years before pinning, I was able to keep the ticking at bay by installing new bearings (not sure that made any difference), running straight distilled water, and an in-line t-stat mod - but it eventually came back. She’s been crazy quiet since the pinning operation - currently over 260K (only pistons, rods, and cam bearings are still original). I did it with a right angle drill without removing the engine, but did remove the crank and replaced all bearings again while I was in there. In hindsight, it would have been cleaner and easier to pull the motor, pin, and rebuild.

 

What year model is your truck and at what mileage did you pin the liners? Thanks!

 

‘04. I’d say I pinned her at about 210K - 50K ago? High mileage.

 

I have a 2004 disco 2 that ticks when idle... am I screwed? Been that way since I bought it about 3 years ago.

 

Its either slipped liner, low oil pressure, or exhaust leak. You can test for hte last two, if it is not those you can pin the liners.

 

I am pretty sure the last two arent the issue, had those checked recently. Any idea on how much that kind of job would cost? Just like to know so I don't get a bad deal/ripped off.

 

vacuum leaks can also cause the tick, especially at idle.

Slipped liner sounds like a hammer on an anvil.
