hi there peeps,i wonder if anyone knows the problem i got?

i changhed the hydraulic lifters and oil and is still doing a weird tapping noise,it does it on idle when its cold,when u rev the engine a bit the noise goes but when it comes back to idle it starts doing the noise again,

weird thing when the engine warmps up the noise goes.

i got the lifters from matt lewis and the oil is good silkolene 10-50

what u reacon peeps beacause its doing my headin.

please help me..................................

 

Can take a while sometimes for the lifters to fully fill up with oil - I've had a noisey lifter that lasted I'd guess a good 30 mins of use. Other times they've gone quiet within minutes.

well i left it running an took it out for a drive lastin about 1 hour all in all,but i started it in the morning an the noise is still their.

could it be the cams?

 

dont wory about it,i did but it always soon clears up,my last ones took 1500miles

 

Check the timing and line the bottom pulley with the lug and pointer not the groove and pointer, when lined with the groove the valve can kiss the pistons and it will sound like tappet rattle.

thanks guys,ill keeep on driving it rouns and hopefully the noise goes......

when yours was tapping,did the noise dissapear when u reved it up.

 

If its valve to piston contact it will stop once its made a big enough dent in the top of the piston i would check all timing is as above before driving any ferther

hay really appreciate this info.....

if it was to be that will the noise go after the engine is warm?

 

It could take a few hundred miles to fully settle, mine did, despite the oilways etc being clean, as flushed out oilways etc.
My car still sounds cammy, but is actually(on mine) piston slap, as it's a bit tired 120,000 + miles now!!

What oil are you using mate??

 

using silkolene 10-50 guys,

hay tabetha,does the noise go after the engine warms up on yours?

 

if it is piston slap,how can it be fixed?

 

rebuild the engine!using 4x4 pistons or con rods cant remember which way round!but piston slap is nothing to worry about fella!persume yours is a 2wd?

 

it's a 4x4.do u reacon it could blow up easy?

 

little ends on the way out??? Worn cam profile??

 

in all truth fella i would not worry bout it!unusual for a 4x4 to get pistonslap!but u have to remember its a cossie these are basic old things really and generally noisey old things when cold!give your tappets a chance to settle in!

 

My noise gets a lot less when warmed up but sounds like a tractor till then.
As said use of 4wd(tractor!!) pistons cures it mostly, but due to the inherant design there will always be a little bit when cold, but a lot more so on 2wd, the gudgeon was moved on 4wd to counter this.
Piston slap causes no harmful effects, and is just a characteristic rather than a fault.
Personally unless it is drinking oil(like mine!!) I would not do anything.

thanks peeps really appreciate this again....
