HI ALL!

Anytime the my car's engine is cold, i get this tapping noise. I do not know if its a Tappet/Lifter or what!!?? But when the engine is up to temperture its fine......any info would be great! 2002 WRX

 

possibly piston slap, without hearing it i would assume its that

 

is that anything to be worried? thanks

 

Which oil are you using?

Tony

 

castrol magnetec 5/30......this is where u tell me its the wrong one?

 

No you can use it, but only the fully synth stuff, I wouldnt use it myself personally, i stick with a 5w40 fully synth as its not noisy on startup

Tony

 

Yes. Well I dont go back to work untill the 4th so I might drain the old stuff out and give the 5/40 a go!

Thanks Tony

 

I thought all magnatec are semi, its the edge that is fully synthetic

 

piston slap isnt really that bad, its quite common

 

Yes its common on forged engines, never had the issue myself with 4 scoobs, 97/98 engines suffered from it badly due to a piston issue, the rest should be ok, especially cast pistons which shouldnt suffer.
It will be down to the oil and the noise will be the tappets.

Tony

 

Lots of engines that seem fine in the summer start to show a bit of slap in the colder weather. It's just audible on my 03 STi just after start in this cold weather.

nowt wrong with abit of slap

 

you should hear my engine on a cold start up, my pistons slap harder than my mom lol but only because i went ott with the piston/bore clearance

 

Its says fully synthetic on the one I have

 

hey thanks to the rest of you lot tho!
