knocking sound

[letemlaf]

hey guys

i have a 33 gtst and i havnt driven it for a few days.

i went to start it just then and theres a really loud knocking sound comming out the engine somewhere.

it sounds like its top end but i dont know if its a bad thing or maybe if its hydrolic lifters (if they have them) or anything that is gonna cost me $$$.

could this be because i havnt driven it in a few days?

I had the same problem about 2 months ago. I think its cause i didnt drive it as you say. Change the oil, start her up and put ur foot on the gas a bit when u turn it on. I did this 2 times and it was ok. U probably have a bad smell coming out of ur exhaust if u have 1?

im a little worried to let loose with my foot on the gas incase i damage something

but i hope thats all it is.

cant smell anything, and theres no smoke.

wish i had some spare oil and id change it now

would you not recommend driving it around the block tonight?

i would not drive it until u change the oil. i let my oil drain overnight. Thats what my mechanic told me to do and it worked. It will take a couple of minutes till sound deadens. Dont drive it hard for a while after u do the oil change. My mate had the same problem in his vl after it had not been driven. He just booted it a few times and it was ok after. I would not do that.

ok ill give that a try

ill change it tomorrow morning and then try that night (12hrs later or so)

did the sound go away before you driven it?

this happened to me. i let my car sit for 6 weeks (had an operation on my arm) and i started it and it was knocking. put a bit of oil in it and it got a bit quieter. I let it idle for 10mins and it was ok after that. Did an oil change afterwards too. Freaked me out for sure!
