Importance of checking Piston to Valve Clearance on Engines

[NTIman]

Go ahead, make fun of me for listening to my Dad about how he thought it would be OK.

Long Story, more details later[/img]

yep, pretty important....

[NTIman]

Yeah, months ago when I put it together, I was waiting for a coworker to loan me his checker springs. Dad was in a hurry, so he decided It would be ok to finish up the engine, and not worry about it. Huge cam, stock everything else. Not good.

I hope nothing like this happens when I get the Daytona going. It seems like it has been so long sense I started putting stuff together...I hope I didn't fuck anything up.

Is (was?) that a rocker arm?

Damn.

Damn.

Pushrod throwing you off? :wink:

[NTIman]

It was and kind of still is, a rocker arm.
I also pulled the intake rocker off of cylinder #2 and its pushrod is also bent, but the rocker looks ok.
I stopped there, because I figure the rest are fucked too.

DO NOT CUT CORNERS ON ENGINE BUILDING

Pushwhat?

[Dave]

what did that come out of?
I have no idea what I'm looking at, but I'd say it is royally F'ed. Bummer dude

you're looking at the pushrod side of the rocker, and as bad as it is, i don't think its royally fucked. the disadvantage to pushrod engine- pushrods, the advantage- pushrods take the beating and can be replaced, a lot of time no other damage occurs.

I had planned on getting roller rockers anyway, so the rocker is not a massive loss, however, the valves may be bent.

Just a question: Would anyone like for me to do a How to post about cam selection, degreeing, and checking piston to valve clearance on a V8 engine?

[Jeff]

I would like to learn more about that. Our 318 in the Challenger does not run because of to hot a cam and nothing else done. So I would like to learn more about why and what I can do to fix it.

That would be cool. WTF is a checker spring? I thought you guys adjusted valve clearance with pushawhatsits.

[NTIman]

Checker spring is a lightweight spring that you replace the valvespring with to check Piston-Valve clearance. It simply allows yo7u to push down on the valve with your hands.

And you can adjust Lash with short pushrods, or adjustable Rocker armns
