'95 engine ticking - any suggestions? - Land Rovers Only

discovermike · 10-18-2005, 06:41 PM

There is a ticking noise coming from the engine of my '95 Discovery.
Just wondering if anyone has any ideas what it might be before I
take it in to be diagnosed. I'm new to the forum, and it's great to
be here - very informative, great site. - Mike

Welcome To LRO, Mike!

We'll need a bit more info on the issue to really help you out...

The ticking comes from the top of the engine block and
when it's most prominent when it's idling. When I press
the gas, the sound is much less noticable.

Mike,
I had a similar issue with my '95 . The cause was the ligher oil that was used when the weather warmed up. It would tick after the engine warmed up particuarly at idle. I changed out to a heavier oil, 5/50 or 20/50 synthetic and the tick went away. When I picked up the rover the origianl owner had 5/30 synthetic but it was in cold weather. Once it warmed up it was just too thin. That was 2 yrs ago, no problems since switching oil. I hope that helps.

Common problem with the 95's. The 3.9L motor has an issue with the rocker arms. When they start to wear, they get just enough "play" in them to cause a tick. It's nothing to be real worried about, but can be fixed.

Some people have luck by just re-torquing the rocker shaft assembly. Just pull the valve covers (they prolly leak anyway, right), and re-toque the bolts.

Worse case, you need a new rocker assembly set. You can pick them up pretty cheep used, <100.00.

Or, as mentioned, add thicker oil to cover the problem up....

Right now, she has 68,669 miles.

I just bought it last week, and it probably hasn't
been driven in a while.
I only have a 60-day engine/transmission warranty.
But I also want to be able to work on it myself.

I changed the oil and put 10W-30 synthetic blend.
Should I have used full synthetic?

I'll retorque the rocker shaft assembly.
How many foot-lbs should the rocker arm assembly
be torqued to?

I really appreciate it, Mike

Mike, check for leaks on the following,

the heads, the valve covers, the timing cover.

if it is bad try to get them to warrantee it.
