Firing order was wrong?
Hi,
Off hand I would check and see if the firing order was correct, roller cam is 13726548 and old 302 is 15426378. That broken piston looks like it fired on the wrong stroke. The engine would run, just down on power. Good Luck, Perry. |
N O T I C E ! ! !
The picture of the SINGLE BROKEN PISTON is NOT the one that came out of the engine this thread is about. It was posted by HOTFINGRS and is out of a totally different motor! Ralph |
Perry, that's normally good info, but since Karl is running a Chebby, it won't help this time. I know, he's strange..
|
Well that's the problem!
Chevy's are a different animal, it still wouldn't hurt to check the F.O.
Perry.:MECOOL: |
Karlos and Boys,
So what did you find or what are the strange things you found. I know it is real easy to spend your buddies money but I might be able to help, give me a call. |
Jeff
I think we are gonna pull the engine today. Not sure if we will have any info tho. Everyone else: Sorry if I didn't explain this is a Cobra that Karl wrecked about 3 yrs ago. He decided to keep it and rebuild it. 4 of us have been working a few half days a week for about 2 1/2 yrs. We have done just about everything from the frame up. We put the original engine, bored 454 chevy, back in it, It hadn't run all that time but seemed to run fine when we got it started up. All Karl has done is drive it around for maybe less than 100 miles when this happened. Sorry for the confusion. |
Thanks Dave,
You may never find the turd that went through the cylinders but check in the intake and exhaust. I hope the left bank is not hurt any worse than what you already found on the right bank. A little solvent poured behind the valves will quickly check for bent valves. A new 540 or 572 would sure test all your suspension modifications. The 540 combo has been refined to a volumetric efficiency level that pump gas yields 700+ flywheel HP. |
What kind of gasoline are you using? Has the fuel been sitting around for 2 1/2 years?
|
It's a chevy engine?
Then, who cares? Just kidding! :LOL: |
Fuel is new. Like I said he has drivin it a little less than 100 miles.
I agree about the Chevy but it is what it is. The other head looks better but it is still beat up some. Gonna tear down the engine on Mon so we will see what other damage there might be. |
Carl.
If you guys ever need any welding done..Let me know..I do it for a living and I am cheap..Only a couple of beers for club members is the normal charge! ;) |
Hey Jets, thanks for the offer. I'll certainly keep you in mind. Where are you located?

Jets, ya better keep Karl's contact info handy, if he ever gets his beast runnin' he'll be needin' a hell of a lot of welding services from ya! :eek:
Been told, he can't control all those chebby ponies under his hood!**) Ralphie, the controller!:p |
Is it possible that some significant moisture got into some cylinders while it was sitting? I'm trying to read the gaskets and they may have failed while the engine sat allowing water to drain into in 2 or 3 cylinders.

Hey Jets, I do remember you, now that you refreshed my memory. Haven't heard or seen anything from you in a long time. Glad you're back on line. If you'd like to send me a PM with your phone number, I can get in contact. Thanks, K.

Tinner. That might get him a 100good miles.or so but what would he do after that?
|
The #2 cylinder may have got cleaned by steam. In other words, a water leak.
Detonation seems like a good explanation. Have you inspected the plugs closely? There may be some evidence on them. |
