Ok.. I was putting my intake manifold back together and I herd this metal clank sound and it could have been anything. It is possible
that something fell inside the engine. Is there any thing I should do to figure out if this is what happend. My friend suggested rolling the
car in 5th and seeing if the engine flows freely. I was wondering if there any other idea out there.

 

Only turn the engine as a last resort- these aren't like piston poppers, where you have plenty of cylinder bore room before you hit TDC...Which manifold were you putting on? If UIM, take it back off and take a good look inside the LIM- sometimes when something falls into the LIM, it doesn't make it into the engine...

 

My friend brian used a shop vac and suck out a nut he dropped in his motor during assembly.

 

It was the LIM that was exposed. I was trying to put on the UIM. I didnt see anything and I felt around. I will try to see if I shop vac it. If that doesnt pull anything am i to try turning it slowly.

 

big magnet- I droped a 10mm wrench down the LIM....... that sucked.... got it out though.

 

heh... that sucks so bad its kinda funny.

losing nuts in the mani is probably worse because its harder to get/less likely to get stuck... but it still sucks

 

better safe than sorry, take off you lower manifold and take a peak in or probe with a magnet. Ifthat doesnt work go throught the exhst ports. If you still cant find it still crank the engine from the main pulley very slowly with a socket wrench (no impact wrench)

 

Been there...it sucks

 

get a shop vack and tape a a little hose at the end and stick it in there and see if you can fish something out
