Heard about a hg job that went bad, loud knocking after assembly. Being that it was out of a 93 240 i figured i should take a look see.

Grimy old motor

Looking at the head i saw a new valve cover stud installed just over the intake port for cyl 1. Can you guess how this happened?

DING DING DING.

Thinkin i'll just mic out some pistons i have laying around and see how much abuse it will take.

Could be a good motor to learn how to tune on when i get the 242 running.

Rather blow this up than my fresh rebuilt B230FT.

I did that in a old 460. It sucked the aircleaner stud in. Cept it knocked the piston sideways and cracked the cylinder.

Just to be clear, iIdidnt do that. I showed up to work and my first job was to strip that block down and see what caused the noise. Since the piston is junk i get the pile for scrap value.

If that's the original cross-hatching in the cylinder, I don't think it'll be out much.

If this a dd on a budget, smooth out all the damage throw in used pistons and go.
reminds me of this thread from a long time ago. I am sad that the videos are no longer on that server. I am sure they are on my desktop at home somewhere though!

This engine will be a fun experment for my drag/auto x 242. I rebuilt a b230 with low comp turbo pistons and spent alot of coin so i really dont want to push that one too much. I think this block will be a good way to play around with higher CR and learn some tuning. Really have nothing but some time invested.

How the hell does one get a valve cover stud inside the engine ?

During the HG job, intake off, ports are exposed and the vc stud was broken. Must have fallen from the extractor into the number one port.

Have a buddy I rally with who had a similar thing happen to his foreign race car. The odd thing? It was an SAE bolt. Just like the ones another guy in his class (who ran a truck) used. Buddy now locks his hood closed when he's not around.

:lol: I did the same thing to my 73 tbird's 460 when I was in highschool.

I was at the track, pulled the aircleaner off, and dropped the nut in (not a wingnut)

I tried to get it out of the carb, but I pushed down the butterfly valve in the carb and it dropped into the manifold.

I started it and headed to the staging lanes. It made some mean noises and then nothing. I guess it destroyed it or kicked it out the exhaust. I pulled the heads later and there were some good nicks on the piston and head
