Sorry to hear that Brian. I hope you caught it before it did major damage.




Will know more when I get the engine out and on the stand where I can tear the rest down.

Sorry to hear about the damage. We have issues as well. I'm about to the point of selling it all.

If it's not one thing, it's another....

Good luck with the fix.

The culprit of the loose valves was destroyed lifters. One completely gone roller....found three pieces of it, no shaft and only five needle bearings up top. Number 1 cylinder is scored and I need to see how bad it is. I am dreading having to re-bore this and buy new pistons for an engine with so few passes.




I'm going through a complete rebuild right now because of a trashed lifter. The oil pump driveshaft was cracked. If that would have went it woulda been far worse.

It amazes me how well they'll run with something going wrong. From now on I'll check things closer if it slows down a tenth or so.

Good luck with it.


Yeah, it's got a smallblock.

havent looked yet to see what the problem is... that'll
wait till I get that engine on the stand... I'll
put the W-9 back in

That sucks but now you know the importance of checking valve lash after every pass. if its loose its a pushrod or lifter or rocker, if its tight the valve is pulling through.

Don't get depressed if it was easy to go fast everybody would be!

Brian sorry to hear about the problem. Hopefully you caught it before any of those little needles did any real damage to things. I am pretty religous about lash. Even once it is stable we still chack it at every race. That does not guarantee no problems but we rarely let it go more than 10 passes without checking it out.

Believe me I feel your pain. Checking mine at a race after it was not running the number it should, and we are talking a few thou off is how we found the bad LSM cam. Cam apparently lost its heat treat and was peeling material off, found it by lash on two cylinders being off. Caught it before it did much damage but I always check it over if it falls off for any reason.

Sorry to hear of the damage Brian! Hope it's nothing too serious!
What lifters are you thinking about dropping into there to replace these ones? You were running Crane Ultra Pro's?

Sorry to see that,Brian!! I know that needle bearings are all the rage but I don't care for them...I thought someone said Harland Sharp was coming out with one that did not have needles on the wheel but I have not seen one yet....Good luck,man!!

They were Crane Ultra Pro's. Don't know what I will use next. Possibly Morel since they have a direct replacement for the Crane with the offset that I need. The offset narrows down my selection and I know the oil holes in the bushings work with the crane (pushrod oiled).

As far as serious, probably nothing $3-$4K won't fix.

Strange thing Al is that it ran the quickest/fastest it ever has on the last pass. I just can't believe that nothing could be heard. But, yes I did fall off of my normal maintenance routine. That won't happen again.

FWIW I have been running Isky EZ Rolls and have had zero isues with the lifters. Plus no needle bearings

The fact that it picked up might say something about the engine combo and camshaft selection Less lift and less duration and you went faster. Then again the few engines I have had that went BOOM, usually ran thier best the previous pass

Sorry about the problem. Those rollers can sneek up and bite you right in the butt.

Its good you found the problems before it cost alot of $$$$, its easy to understand how some things can run well but still have issues.

Take tractor pulling for instance, everytime we brought home first we would find the most damage on post evenet inspections. Or the top fuel guy who wins but burns two pistons doing it

Highly disappointed in the findings from tearing down this engine. Seems there are problems at every turn so far.

The heads are at a professional shop to get checked out. If you are reading this and missed the first part, the easy thing to check for me was the valve springs were set up with a installed height that was over .200" from coil bind. Further inspection is finding the following: wrong length valves for the heads, tips of intake valves beat up, intake valves with less than acceptable margin, valve guides with up to .007" clearance, several exhaust valves not even sealing to the seats, etc..

Remember this engine has only about 60 passes on it. I don't think it would have stayed together much longer (in the valvetrain) and it seems that it is a good thing that the improper spring set-up caused the lifter failure or I might have run this until a catastrophic failure occured. These problems didn't just happen in 60 passes....they were there from the start.

It will be put together right this time and should finally run to it's potential.

Wow.....

Lucky that thing didn't really hurt itself.

sorry to hear of your loss. I definately know what you're going through as our latest W5 combo banged in two passes. Question for the engine guys watching this: So you are at the track, pull the covers after a few passes and find a rocker that is loose. How "loose" would it take to pull the plug on the day and tear it down hoping to possibly find something?

I was wondering how long of a valve do you run? What is the installed height? And, you should check you lash more frequently, after every time out, don't be lazy and assume everything is ok.
