engine taredown results,REBUILD. - 09/26/10 09:44 PM

she just needs barings and head gaskets and i will get head studs as i think it is time for the bolts to be replaced.

i will give the parts a good cleaning and start to reassemble for next yr.the head bolts were not as tight as thay should be but i have not had to retorque them in the past and have checked them.

I aint never had that much intrusion of combustion gases onto the face of a copper gasket....like you were saying either not enough tension on the bolts or some serious detonation..though pistons all look fine, correct...with the amount of water getting into the cylinders also you must have had a sealing problem.....I always use permatex 300 slathered on all 4 surfaces and never a water, oil or cumbustion leak before.

thanks for the link she was leaking bad forsure.
i have to clean the cylinder wall before i pull the pistons to try to save the rings that are new.on some pistons all in the quench area on the carbon buildup only you could see signs of detonation on 3 of the pistons.looks like i got lucky.

about 4 dyno pulls and 7 passes.i am sure the head bolts were loose from the start and i should have noticed it on the dyno.the head bolts[ARP] are older[10 yrs] with about 8 retorques.

Sorry to hear about the problems Metal Storm, hopefully they get resolved soon so you can get that thing running again

Just reinstall those old head bolts with lockwashers on them, and you'll be good for another 10 years.

I'd be lookin' at why those bearings don't show a little more even wear across the surface. Crank flexing, block flexing, caps walking, tapered or hourglass journals... gotta' be a reason. I'd mic that crank all over all its journals, maybe set the block up for a light swish with the line hone to see if the main line is still straight.

i was just looking at the clevite site trying to figure out what is going on.i did have low oil psi.[40psi all rpm]

Re: engine taredown results, - 09/29/10 01:47 AM

the block is new Koleno and hope it is correct.thye line bore was measured with a bore mic.the crank is fresh back from moldex[440source] from being corrected .010/.010 and heat treated.Thanks for saying something!your thaughts appreciated!

Are those bearings from the crank after it came back from moldex or before ?

after! all of the barings are like that!

I've seen that on a direct from the source crank.

That is caused by the crank contacting the bearing , which it shouldn't , I'd be showing those to Moldex and asking what the bleep.

i am waiting for a call from the engine shop to see if thay call or me.i will call monday i am sure and get the ball rolling.

Re: engine taredown results, - 10/02/10 03:14 AM

Mike,not good! Do you know if Whitey is still employed at Moldex? He did the machine work and measurements on my forged factory crank back in 2000! He was the MAIN MAN! He might be retired by now,as he was getting up there in years back in 2000. He did VERY GOOD WORK for a lot of racers...and for a lot of years!

Posted By: blownzoom440

Re: engine taredown results, - 10/02/10 03:34 AM

i think that is who looked at the crank but maybe not the work.looks like i will need a new crank unless it is all welded and reground if that is doable.

i wont pay for the work!if i get a new crank,

Posted By: blownzoom440

Re: engine taredown results, - 10/02/10 03:49 AM

this wont be over any time soon i am sure.the koffels were very helpfull getting the crank there,back last time.now proving the defect and resolving will be a whole nother deal.

Posted By: Labratt

Re: engine taredown results, - 10/02/10 03:58 AM

Unfrigginbelievable!

If Whitey did indeed check it..hard to believe he'd let it out the door!

Sorry for your misfortunes! And hopefully they resolve it accordingly!

Re: engine taredown results, - 10/02/10 07:48 PM

but wait,there's more!

i cant even get this baring off the cam.i think that is where my oil psi went with that leak.

Posted By: hemi-itis

Re: engine teardown results, - 10/05/10 01:52 AM

i was just looking at the clevite site trying to figure out what is going on.i did have low oil psi.[40psi all rpm]

What was the oil pressure on the dyno??O/P told you there was a problem.Who installed the cam,was it tight from the start?

the psi on the dyno was 65# after putting restrictors in the heads to the rockers.with having full time flow to the heads witrh the koleno block it is needed.the psi dropped after i ran a test tune the week befor the classic.scott koffel installed the cam barings and cam and it was tight from the start. i believe the baring had came partialy out taking out the cam and re installing it and it finished at the track.

edit:only # 3/5 baring are effected with 5 came out and 3 has a lot of wear.the block where #5 goes looks in good shape.

Re: engine teardown results, - 10/05/10 03:34 AM

Well Mike,you'll know next time the o/p drops for any reason to just turn the key off and pray!

i cut the bearing off.nickedup a lobe but i hope i can still use the cam.i cut it off the cam.

what you want to see the scratch in the cam lobe?there is a pic 4 posts up of the bearing on the cam.enough for now with the pics.thanks for wanting to look at things though.thanks everyone for your help.this is going to take time and i am sure people here are tired of me.i will get her fixedup.

Posted By: blownzoom440

Re: engine taredown results, - 10/15/10 09:23 PM

i had the crank looked at today for taper and it checked good.i will have the rod big end looked at next week to see if we can find a reason for the bearing wear pattern.i will get some cam bearings this weekend and measure for the rear bearing if it needs fitted.stay tuned.

Posted By: blownzoom440

Re: engine taredown results, - 10/21/10 10:32 PM

i have all the parts to get her back togather.just the block work left.

Posted By: blownzoom440

Re: engine taredown results, - 10/23/10 09:50 PM

fitted new cam bearings at koffels and it all looks good to clean,assemble.

there was some pinch from the oil hole being drilled it looks like pushing down on the bearing and making the cam tight but it still turned.the bearing bore in the block is fine.cam turns by hand.

all winter to get it togather.see ya in the spring with results.

It's PAYBACK time and i'm bringing he ## with me "THE CLANTONS"

picked up the block with a fresh hone to cleanup some scrapes.only took .001 so i can start to assemble with new rings this weekend and install in the spring.no dyno time as it should be good to go with no bugs to workout.
