carrots 1 Posted April 21, 2010 ive got a 1.8kr.the tappets make a noise untill its got to its normal temp.ive been using 10w 40w semi in it.ive been thinking of useing 15w 40w mineral .has anyone else used this.i thought it might stay in the tappets longer Quote Share this post Link to post Share on other sites
dbug 0 Posted April 21, 2010 just use the cheap 10/40 from gsf in my kr. its normally a semi synthetic. noisy tappets will probably mean they need swapping out, but if you have used fully synth then it will have been too thin an oil and you want to drop it quick before you do any perm damage.

carrots 1 Posted April 21, 2010 its got semi syn in it now,but thought 15w 40w mite be beter as its a bit thicker Quote Share this post Link to post Share on other sites
Jim 2 Posted April 21, 2010 My previous 16v had noisy tappets till I got em replaced but did find a swap to 15w40 did help quieten them down a little. There's no way round it though.. if you don't want noisy tappets, you need new ones :( Quote Share this post Link to post Share on other sites
carrots 1 Posted April 21, 2010 i think i will try the 15w 40w.when you think about it i bet they put that in it when it got seviced when it was new Quote Share this post Link to post Share on other sites
steveo29 0 Posted April 22, 2010 surley thinner is what you want if you want to get around the problem...the noise goes away when the oil gets hot and thinner ive had success with running atf oil mixed in for a few hundred miles,it cleans them out ...not everyone is a fan of flushing oils though Quote Share this post Link to post Share on other sites
dbug 0 Posted April 22, 2010 surley thinner is what you want if you want to get around the problem...the noise goes away when the oil gets hot and thinner nah - it works the other way round with oil you want it thin when cold and stickier when warm so it coats parts rather than just bathing it. ok it does get runnier when hot and you normally warm it up to drop it out but its the physical property of the oil not the fluidity that does the magic bit. hope that makes sense. synthetic oil is very 'thin' when cold due to the tight tollerences that are found in hi-po engines so thats why you use it in V engines, but in our 20 year old 4 pot lumps they didn't build them to the same tollerence and thats why it costs us £10 for a gallon not £45 :clap: hope this helps.

carrots 1 Posted April 22, 2010 shall i try some 15w 40w then,i reckon it wont drain out the tappets as quick when the cars standing Quote Share this post Link to post Share on other sites
__Andy__ 0 Posted April 23, 2010 shall i try some 15w 40w then,i reckon it wont drain out the tappets as quick when the cars standing new tappets buddy, if uve been using the fuchs titan xtr 10w40 from gsf its very good oil, a thicker oil may quiet that tappets down a little but at the end of the day corrados are old cars and will need things replacing... if its overly excessive tapping then check your oil pump!
