hey everyone , new to the forum and new to 350s. looking to get some help from the experts.
so recently i bought my first 350, 80 k on it and excellent condition from what i can tell.

anyway i bought it saftied and etested and was pretty confident with the purchase with the pretty low km.
car seemed to run great and sounded good too..
2 days in of having it i started to notice a slightly rough idle but didn't think to much of it but then my aces light came on. since then its gone off them came back on twice. some times it idles fine some times it doesn't.
i contacted the seller he and thought the intake got wet or it needed a plug or something. so i ordered a cover for the intake and got the code checked . p0300 , so random misfire. i took it to a local shop and the used a camera scope to check it out and they said they could see all the cylinders misfiring randomly. they checked my spark plugs and some of them had oil on them
. immediately he said to go any further he's going to have to risk breaking the wiring harness to find out for sure which is approx 800 to replace for parts and labour. he said without checking he thinks its a bent valve..ouch. but after doing some research i fund out it could be many other things like seals. Im no car expert but i feel like id be noticing a lot poorer performance from a bent guide? not to mention it has low km and has never been raced or on a track (apparently).
i looked up videos on replacing seals and it looks like a pretty big job compared to other engines iv seen.
does anyone have any similar experiences or and ideas of what it could be or if they agree with that mechanic? i know I'm probably going to have to get someone to start digging for the problem regardless. but the shop told me id be looking at approx 2300 bucks for parts and labour for bent guide.. i could almost get a new engine for that.. maybe he's just taking me for a ride? i don't know .. any input at all would be greatly appreciated
Rob.
