Engine build

Just for giggles I checked to see if any of the head bolts lost some torque, but they were all tight.

Dag nabbit!

Well, knowing you (speedy), you'll have the thing back together yesterday.

LOL

Well time is running out, I need this damn thing working for the summer months, I gotta trailer to haul!

Actually what I really need is a spare truck so I can just switch em out when they break.

So something has been bugging me...........why cylinder #1?

Rod popped out of #1 in my old engine, and blew a gasket on #1 on the new engine.

This is a completely different engine, crank, cam, block, heads, injectors, so what is the culprit?

Just a coincidence, tuning related, or engine design?

[cleatus12r]

I'm hoping it's just a coincidence for you. I can't see any common denominators at this time.....like you said....everything's different.

We can always blame the CMP sensor.

I was reading about fuel bowl deletion. They stated that one of the cylinders gets starved of fuel with the fuel bowl. Also do you have a blow off valve?

I see one common denomonater....
















... the loose nut behind the wheel

[907DAVE]

I do have a regulated return setup, along with a fuel bowl delete.
No, I do not have a blow off valve.


The only thing I can think of is crank flex. Not sure how much these crank's twist, but if there was any, #1 cylinder would have the most advanced timing.
