Stu Posted March 26, 2009 Share Posted March 26, 2009 Checked oil level? Link to comment Share on other sites More sharing options...
Zapnut Posted March 26, 2009 Author Share Posted March 26, 2009 Yep oil is at max, wouldn't a lack of oil mean the tapping wouldn't always stay there? Link to comment Share on other sites More sharing options...
ScORTED Posted March 26, 2009 Share Posted March 26, 2009 its the tappets filling up it takes awhile to get the oil up, try an engine flush and some good quality oil Link to comment Share on other sites More sharing options...

escort4x4 Posted March 26, 2009 Share Posted March 26, 2009 oil pressure relief valve, these have a tendancy to loosen off, good chance its that mate or you are using thin oil Link to comment Share on other sites More sharing options...

escort4x4 Posted March 26, 2009 Share Posted March 26, 2009 take the sump off job mate Link to comment Share on other sites More sharing options...
mar_k Posted March 27, 2009 Share Posted March 27, 2009 take the sump off job mate no its not. you need to remove the bottom part of the timing chain cover, remove the oil pump chain and you will see the oil pump. you will need to lower the engine slightly on the drivers side to gain access to the pump, as you look at the pump on the top left you will see the pressuse release valve, remove the pump and then remove the valve, give it a good clean with petrol then apply locktite and refit. you will need to fit a new seal to the pump and another new seal to the lower timing chain cover once your ready to refit it. its not as hard as it sound. does sound like this will be the cause of your problem though. ill try and post up some pics later Link to comment Share on other sites More sharing options...
mar_k Posted March 27, 2009 Share Posted March 27, 2009 i forgot to mention you will need new oil seals for the oil pump and timing chain cover Link to comment Share on other sites More sharing options...
speedy Posted March 27, 2009 Share Posted March 27, 2009 practicaly imposible to diagnose online without seeing and hearing the problem but more than likely lifters loosing oil Link to comment Share on other sites More sharing options...
escort4x4 Posted March 27, 2009 Share Posted March 27, 2009 my apologies, so its not a straight n simple job, and also like said not diagnose on the net, but if ya like do a aoil change and use thicker oil, if this shuts the lifters up then you should be ok Link to comment Share on other sites More sharing options...
mar_k Posted March 27, 2009 Share Posted March 27, 2009 no your right you cant diagnose a problem over the net but i put 99% on it being the relive valve, every rs2k suffers from this at some stage. dont really hear of them losing oil as such just low pressure Link to comment Share on other sites More sharing options...
speedy Posted March 28, 2009 Share Posted March 28, 2009 best bet is to get an engine flush run that to clean any Shite out the engine change the oil for some high quality stuff not just whats cheepest in halfords then put in with the new oil a valve lifter treatment if it gets better its the lifters if not then as above be worth looking into the relive valve Link to comment Share on other sites More sharing options...
Zapnut Posted April 6, 2009 Author Share Posted April 6, 2009 Thanks for all the help, i have given it a good clean and fluch and and oil change, seems better now still makes the noise a bit so will take a look at that valve. Thanks again! Link to comment Share on other sites More sharing options...
