hi first post and all ready having problems, imported a 97 leggy gtb from japland when it arrived all was sweet. has been sitting around for 6-7months when i started it up earlier in the week there is a tapping/knocking noise sounds a little like big ends, but it's there all the time and does not get louder when u hold the throttle and let off slightly. just tapps faster at higher revs. is this terminal?

 

hi,
i had this same problem. my 93 wrx spent 2 months on sitting on the boat. when i started it a few days after it landed, it sounded like big end was knocking and it also had a loud tick from a tappet.
i was that convinced engine was knackered that i booked the car in to have the work done and left it in my garage for a few weeks. then when i drove the car down to the garage to have the work done noise slowley disapeared! The car would still tick for a few days but that cleared too!
I just kept it topped up with oil and ran it for a week or so and now the car runs sweet as a nut.
I do still get a pistonslap noise in the morning but it clears when warm.
Try running it for a bit off bost (check oil level) and see if it clears. mine did.

 

wont go mad pulling it to bits yet then! need to get it regestered and on the road so i can have a drive and investigate further if it does not clear up.

 

i just rebuilt mine and it taps alot when cold not sure what it is though it dosent sound like bigends

 

sounds the same as my problem i had.....took to afew garages and they all said engine was fooked get ready for a 4 figure sum so last call went to subaru montys of sheffield glad i did because after leaving #219 over night they rang me up and said all is fixed it was the coil pack which was fooked £100+ish was music to my ears

 

was the coil pack causing a knocking noise then? how?

 

yep deffo coil pack....got told one of the leads was adrift (number 4) and was not doing its job or summut like that...but soon was sorted....

is the noise coming from round the coil pack/washer bottle area ?
