tap...tap
Hi there today i was going over my engine and when i first started her i could era a tapping sound...so listerned a little closer and it sounds like it coming from the middle of the engine and i goes a little quieter when warm.
Any ideas what this tapping sound could be or what i can do myself to stop it. Also when the cars warm its idleing just under 1k rpm is that normal... I'm planning to do a oil and filter change the weekend so what oil would be the best. its a 98 uk impreza 2000 turbo. thanks daz. |

Sounds like the good 'ol cold weather piston slap. Not uncommon on any engine when the temp. drops. It was a known characteristic on '98 cars. As long as it quietens down as the engine warms, it's ok. Warm the engine gently during this period.
It should idle at around 750 rpm when warm. Use a good quality 10w/40 Do a search for oil change procedures, it's a bit of an emotive subject on here! JohnD |
big help

JohnD Thanks johnD for the reply it does die off when warm... I have noticed the posts on here about oil change procedures, is there a special way to do them on a scooby, i've done loads of them on other cars... Anyway thanks again big help. |
As soon as the temperature drops the piston slap comes around. As above if it goes away after a few minutes, it's nothing to worry about.

However, filling the oil filter prior to fitting it, and disconnecting the crank position sensor (or pulling the ECU power fuse) so you can rotate the engine on the starter and establish oil pressure prior to allowing it to fire, are easily done, eminently sensible ideas that will do your engine no harm, and protect it from any cumulative, harmful effects it might otherwise suffer as a result of being temporarily being starved of oil for a few seconds as you start it up for the first time. |
thanks for the info splitpin i will remember them simple procedures when doing my oil and filter change.
first ever scooby so a bit well lets just say under educated so every bit of knowledge welcome... thanks daz. |
