Hey guys :

The weather has been cold up here in Candada forthe past 3 weeks. between -4 and -10 My disco started making clapping/tapping soundz on startup . i did an oil change and switched to 5w 30 the sound is still there on startup. but it goes away as soon as the engine warms up. is this a valve clp/tap and should I be concerned?

 

I assume that you are using a synthetic 5W30. In cold weather synthetic flows much better than Dino oil.

 

No i am using dino oil and have for 2 years . with no problems.. Anything ring a bell as far as the tapping tapping sound?and why it stopps when the engine warms up?

 

Good evening,
Have a couple of questions?
1. What is your oil pressure like?
2. How many mile on the Disco
You might need to do the ATF treatment to the motor......Just a thought.

Dont worry about it.
DII's are known for this, apparently the rocker arms are aluminum with steel liners in the cup that the lifter goes into and these liners wear/come loose and rattle.
The good news is it will get worse and do it all the time, the bad news is it will do this for the rest of its life.
If you switch to full syn you can prolong the onset of a full blown lifter noise when your truck is running.

 

The tapping noise comes from your lifters, rockers , tappets, etc. After it warms up the noise goes away because the lifters are able to receive oil pressure to build up the gap. Thinner oil flows better in engines that have sludge issues. RoverTCV8 has a point with the ATF treatment, as ATF is a detergent and it helps clear up sludge.

 

Thanks guys Your the best!!!

for the love of god put synthetic in there,,,

its sitting right on the shelf next to that archaic crap called conventional motor oil. your engine will thank you for it.

 

Im going to do this very soon

After all..
Its not a Rover if its not Leaking..

And I want to be part of the CLUB!!

 

then there must be something wrong with my 04 then because i swapped to synthetic as soon as i bought it and it does not leak[:-]
